Abstract
PURPOSE Miscarriage is one of the most common complications of pregnancy. Although chromosomal abnormalities of the embryo is a well-known cause of miscarriage, a lot of cases remain unexplained, with immunologic and vascular growth alterations being considered as probable causes. Chemokines are produced by a variety of cells and exhibit several functions including both pro and anti-angiogenic properties. In this study, we investigated the role of the angiogenic and angiostatic chemokines in placenta and decidua tissues from spontaneous and induced abortions. METHODS Total RNA was extracted from the placenta and decidua tissues, which was then purified and converted into cDNA. Real-time PCR was then performed for the expression of the angiogenic CCL2, CCL5, CCL20, CXCL1, CXCL2, CXCL3, CXCL5, CXCL6, CXCL7, CXCL8 and CXCL4, and the angiostatic CXCL9, CXCL10, CXCL11, CXCL12 and CXCL14 and results were then statistically analyzed. RESULTS Regarding the placenta, CXCL7 (2.29-fold, 2.16-2.38, p < 0.05), CXCL4 (1.01-fold, 0.74-4.447, p < 0.05), CXCL9 (0.87-fold, 0.43-1.34, p < 0.05) and CXCL11 (0.31-fold, 0.22-0.45, p < 0.05) were altered in spontaneous abortions. CCL2, CCL5, CXCL2-3, CXCL8, CXCL10, CXCL12 and CXCL14 were not statistically significant altered. Regarding the decidua, CXCL7 (7.13-fold, 6.32-7.54, p < 0.01), CXCL8 (11.02-fold, 8.58-13.45, p < 0.05), CCL20 (1.21-fold, 0.29-1.89, p < 0.05) and CXCL9 (5.49-fold, 3.67-6.39, p < 0.05) were overexpressed in spontaneous abortions. CXCL2-4, CCL2, CCL5, CXCL10-12 and CXCL14 did not show any differences. The expression of the chemokines CXCL1, CXCL5-6 was absent in either tissue or group. CONCLUSION Our results show that the overexpression of angiostatic and diminished expression of angiogenic chemokines takes place in the placenta and decidua of spontaneous abortions, suggesting that dysregulation of angiogenesis could be a contributive factor to the pathogenesis of miscarriage.

Abstract
OBJECTIVE The aim of this study was to examine the role of growth factors associated with angiogenesis and oxidative stress in the pathogenesis of spontaneous miscarriage. METHODS We performed a comparative mRNA expression analysis of VEGF, PlGF, Flt-1, Angiogenin and Endoglin using Real-Time PCR, in the placenta and decidua collected from 12 patients presenting with spontaneous abortion and from 14 women undergoing induced abortion, during the first and second trimester of pregnancy. RESULTS The mRNA expression of Flt-1 was significantly upregulated in the placenta of spontaneous abortions (5.17-fold, IQR: 2.72-9.11, p < 0.01). The placental expression of the soluble isoforms of Flt-1, sFlt-1 e15a and sFlt-1 i13, was also significantly upregulated in spontaneous abortions (sFlt-1 e15a: 2.35-fold, IQR: 0.98-2.83, p < 0.01; sFlt-1 i13: 3.47-fold, IQR: 2.37-5.08, p < 0,05). Placental tmFlt-1, PlGF and Endoglin showed a tendency of higher expression levels in spontaneous abortions, although they did not reach statistical significance (tmFlt-1: 7.42-fold, IQR: 3.58-14.32; PlGF: 2.36-fold, IQR: 0.90-4.12; Endoglin: 1.97-fold, IQR: 1.18-2.43). VEGF and Angiogenin mRNA expression in induced, as well as in spontaneous abortions, did not convey any statistically significant difference. In the decidua, the expression levels of Flt-1 and its splice variants sFlt-1 e15a, sFlt-1 i13 and tmFlt-1 did not show any statistically significant differences, as was the case for the rest of the herein examined growth factors. CONCLUSIONS In this study, we observed higher levels of sFlt-1 mRNA expression in the placenta of spontaneous abortions, while expression of other growth factors in placenta and decidua remained constant. This suggests that an imbalance of sFlt-1 expression in the placenta might contribute to the pathogenesis of spontaneous abortion, probably via oxidative stress, providing a possible biomarker for prompt identification of this condition.

Abstract
Uncertainty exists concerning the type, adjunct, or dose of regimen to offer in frozen cycles in infertile women undergoing IVF/ICSI. Current systematic reviews have failed to identify one method of endometrial preparation as being more effective than another, whereas many IVF Units use variable and mixed protocols mainly based on their experience and convenience of use. Thus, we performed a four-center two-arm retrospective cohort study, encompassing 439 cycles in 311 women. The modalities analyzed were: Modified natural cycle without and with luteal support (Groups 1,2) and Hormone Replacement cycle (HRC) with and without GnRHa suppression (Groups 3,4). Various schemes of progesterone and estradiol were used and compared. χ2 tests for categorical data and t-tests for continuous data were employed, stratifying by exposure, along with univariate and multivariable Logistic Regression models and subgroup analyses, according to the number of embryos transferred (1 vs. ≥2) and day of transfer (d2 vs. d5). Group 3 presented with statistically significant higher live birth and miscarriage rates in comparison to Group 4 (RR = 5.87, 95%CI: 2.44-14.14 and RR = 0.19, 95%CI: 0.06-0.60, respectively), findings that persisted in subgroup analyses according to the day of transfer and the number of embryos transferred. Progesterone administration through the combination of vaginal tabs and gel was associated with lower clinical pregnancy rates when compared to tabs (RR = 0.19, 95%CI: 0.05-0.71). The stable estrogen protocol compared to increasing estrogen at day 5 was associated with a higher positive hCG test and clinical pregnancy rate, while the progesterone through vaginal tabs was linked with lower miscarriages compared either with gel or combinations. In conclusion, HRC with GnRHa appears to be superior to HRC without GnRHa, concerning live birth and miscarriage, especially when the number of embryos transferred are ≥2 and irrespective of day of transfer. The use of progesterone vaginal tabs compared to gel or combinations is associated with better outcomes. Age is a significant predictor of a negative hCG test and clinical pregnancy rates. A properly conducted RCT is needed to evaluate the optimal frozen embryo transfer preparation strategy.Abbreviations: SD: standard deviation; BMI: body mass index; PCOS: polycystic ovarian syndrome; IQR: interquartile range; FSH: follicle-stimulating hormone; LH: luteinizing hormone; TSH: thyroid-stimulating hormone.

Significance of changes in inflammatory parameters following uterine artery embolization in pre-menopausal females. Exp Ther Med 2020; 19:3684-3690. [PMID: 32346432 PMCID: PMC7185183 DOI: 10.3892/etm.2020.8652] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2019] [Accepted: 12/19/2019] [Indexed: 12/29/2022] Open
Abstract
The purpose of the present study was to describe the course of changes in laboratory inflammatory markers following bilateral uterine artery embolization (UAE) as a treatment for leiomyomas and adenomyosis. The body temperature was measured and blood samples were collected to determine white blood cell (WBC) count and C-reactive protein (CRP) levels in 270 patients on the day prior to UAE and for up to 4 days post-embolization. Aside from a single case with a non-inflammatory complication, none of the other cases had any complications. Post-UAE leukocytosis with a mean maximum value of 10.8±3.5x109/l (range, 5.9-18.6x109/l) was observed one-year post-intervention. The mean leukocyte numbers were indicated to be higher on day 3 post-UAE. The CRP level was also increased post-UAE, with a mean maximum value of 7.75±3.5 mg/dl. Maximum levels were reached in 8 patients on the 2nd and in 11 patients on the 3rd post-operative day. The maximum pain score was ~5.5 and reached its lowest level at the end of the 12th week post-intervention. The present study did not consider an association between the embolic material used or uterus size with the level of treatment success. No complications were observed post-UAE; however, a significant increase in the WBC count was observed within the first 3 days, indicating mild leukocytosis.

Abstract
PURPOSE To investigate the possible association between ABO blood types and breast cancer in Greek women. METHODS 202 female patients with breast cancer and 139 healthy women as control group were examined clinically and with breast ultrasound and those older than 40 years, also with bilateral digital mammography. RESULTS In the case-group, 26.7% had blood group O, 5.5% had blood group B, 61.9% had blood group A and 5.9% had blood group AB. In the control-group, 47.5% had blood group O, 13.7% had blood group B, 31.6% had blood group A and 7.2% had blood group AB. Usage of diagrams with the percentages of frequency, the average control, Pearson, Spearman, Student's t-tests analyzed with SPSS statistical software showed a significant correlation between breast cancer and blood group A (p<0.01). CONCLUSIONS Although in the literature it is controversial whether ABO/Rh blood groups have association with breast cancer, the results of our study show a significant correlation between breast cancer and blood group A.

Abstract
To compare the effects of the administration of low-molecular-weight heparin (LMWH) in subfertile patients with two or more unsuccessful IVF/ICSI cycles. In this six-center two-arm retrospective cohort study, the study population (230 women) underwent a GnRH-antagonist protocol and was classified into two groups, according to the couse of LMWH or not. Groups were compared regarding the clinical and IVF/ICSI cycle characteristics and reproductive outcomes, whereas clinical pregnancy and miscarriage constituted the primary endpoints. Logistic regression analysis was performed to determine the potential predictors of clinical pregnancy, miscarriage and live birth rates using the Enter method. Baseline characteristics were comparable in the two groups. There was no statistically significant difference between the two study groups with regard neither to clinical pregnancy and miscarriage rates (33/133 vs. 20/97, p = .456 and 15/133 vs. 9/97, p = .624, respectively), nor to the secondary outcomes preset for this study (all p values >.05). Logistic regression revealed that age of the woman and ICSI and dose of gonadotrophins used were predictors of clinical pregnancy and live birth, respectively. In conclusion, there is no evidence to support the standard addition of LMWH in patients with two or more unsuccessful IVF/ICSI cycles.

Abstract
PURPOSE Ovarian cancer is the most common cause of gynecologic cancer death. Considering that diagnosis of ovarian cancer is done in advanced stage in most cases, the purpose of this study was to construct a "new risk malignancy index" (NRMI) to assess the risk of ovarian cancer in women with a pelvic mass. METHODS The index includes the classical vaginal ultrasound and CA125 tumor marker along with risk and protective factors for ovarian malignancy. RESULTS Compared to the original Risk Malignancy Index (RMI), NRMI found retrospectively a greater number of patients with ovarian cancer. CONCLUSIONS NRMI seems to be a promising tool for the early and reliable detection of cases with ovarian malignancy in an effort to maximize surgical benefits.

Abstract
To evaluate the effect of endometrial injury on clinical outcomes in subfertile women with repeated implantation failures (RIF) undergoing assisted reproduction. In this prospective nonrandomized controlled trial, 103 subfertile women with RIF were included. Fifty-one underwent endometrial injury through hysteroscopy in the early follicular phase of the previous cycle and 52 underwent the standard protocol without any intervention. Live birth and miscarriage were the primary outcomes. Clinical and in vitro fertilization (IVF) cycle characteristics, were also compared between groups. Both groups were comparable in terms of baseline and cycle characteristics. Live birth rates were significantly higher in the study, compared with the control group (18/51 vs. 8/52, odds ratio (OR) = 0.25; 95% confidence interval (CI) = 0.10-0.64; p = 0.020), although miscarriage rates were similar (7/51 vs. 10/52, OR= 0.25; 95%CI= 0.12-0.66; p = 0.452). The rest of the outcomes parameters were comparable between groups. Logistic regression analysis revealed that endometrial injury and duration of subfertility were independent predictors of live birth after control of other variables (OR = 2.818; 95%CI = 1.044-7.605; p = 0.041 and OR = 0.674; 95%CI = 0.461-0.985, p = 0.042, respectively). Endometrial injury induced through office hysteroscopy in the preceding cycle in subfertile women with RIF improves live birth rates.

Abstract
PURPOSE The aim of this preliminary study was to evaluate and compare MTAI andMTA3 antigens expression in normal and preeclamptic placentas in order to demonstrate their possible functional relationship during pathogenesis of preeclampsia. MATERIALS AND METHODS A series including 20 paraffin-embedded placentas, ten of which originated from normal patients and ten from preeclamptic patients, that were examined by immunohistochemistry using the polyclonal antibodies MTAI and MTA3. RESULTS The results of this study showed a positive nuclear staining reaction against MTAI and MTA3 in both normal and preeclamptic placentas. However, in preeclamptic chorionic villi, cytotrophoblast and syncytiotrophoblast cells demonstrated increased expression of MTAI and MTA3 than in normal ones. CONCLUSION The present observations indicate a potential role for MTAI and MTA3 for normal human placental function, playing an essential role in the pathogenesis of preeclampsia. Nevertheless, the precise relationship between these antigens' expression and pathological pregnancies remains to be elucidated.

Abstract
Homer's syndrome (HS) is based on dysfunction of symphathetic nervous system at the cervical canal. The signs of the syndrome occur on the same side as the lesion of the sympathetic trunk and include: a constricted pupil, a weak-droopy eyelid, apparent decreased sweating, and with or without inset eyeball. HS has been observed as a rare complication of epidural anaesthesia in obstetrics during labour or cesarean section. In parturients, it warrants further investigation as other serious causes must be excluded, such as pancoast tumours, thoracic aortic aneurysms, carotid dissection, neuroblastoma, and brainstem vascular malformation. Management involves early diagnosis of the underlying benign condition while treatment is based on appropriate conservative observation, as most often the syndrome resolves spontaneously. However in very rare cases immediate medical or surgical management is needed.

Abstract
Aim The purpose of this study was to examine various hormonal, biochemical and environmental factors (i.e., smoking and alcohol intake) and to investigate their possible correlation to the development of polycystic ovary syndrome (PCOS). The main objective was to evaluate the associations between hormonal profile and the antimüllerian hormone (AMH) levels in PCOS patients and their relation to environmental factors. Patients and Methods In two gynecological clinics, 38 women with PCOS (defined according to the Rotterdam criteria) were enrolled and observed in relation to AMH, follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T), Δ4-androstendione (Δ4-A), dehydroepiandrosterone sulfate (DHEA-S) and glucose plasma concentrations. Obesity, smoking and alcohol exposure were also studied. Results AMH, T, Δ4-Α, DHEA-S, LH and FSH were increased in 76.3%, 50%, 31.8%, 23.7%, 21% and 18.4% of the patients, respectively. The LH/FSH ratio and glucose concentrations increased abnormally in 18.4% and 15.8% of the patients, respectively. AMH and T levels were both increased in 47.4% of the patients whereas both AMH and LH levels increased in 21% of the patients. Smoking, alcohol intake, obesity and glucose concentrations were not associated with AMH concentrations. On the contrary, high levels of T and LH were linked to higher levels of AMH. FSH concentrations were not increased in these patients. Conclusion AMH is an important hormonal parameter for the diagnosis of PCOS. Larger clinical controlled studies are necessary in an effort to further investigate the inclusion of AMH measurement in the diagnostic criteria of PCOS.

Abstract
PURPOSE We sought to examine whether a preoperative assessment with usual means, available in most hospitals (preoperative histology, pelvic MRI, serum CA-125) can confidently exclude from a full staging surgical procedure low-risk endometrial carcinoma (EC) patients according to ESMO-ESTRO-ESGO criteria (stage I endometrioid EC, grade 1 or 2, myometrial invasion <50% and negative lymphovascular space invasion). METHODS We retrospectively identified all EC patients that underwent total hysterectomy with bilateral salpingo-oophorectomy (TH-BSO) plus lymph node dissection (LND) as primary treatment for endometrioid tumors from January, 2000 to December, 2010. Extensive review was made through patients' medical records. Having set the final pathology report as the "gold standard", we applied the ESMO-ESGO-ESTRO criteria to classify patients into risk categories (low-risk and non-low risk). We also evaluated preoperative risk status using combined data from preoperative biopsy, pelvic MRI and serum CA-125. We classified patients according to the following criteria: grade 1 or 2 on preoperative histology, myometrial invasion on MRI <50% and serum CA-125 <35 IU/ml, in low risk group. Receiver operating characteristic (ROC) curves were plotted. The area under the ROC curve (AUC), quantifying the overall ability of the combined preoperative assessment to discriminate between patients at low and non-low risk, was the primary outcome of our study. False negative rate was the secondary outcome. RESULTS Preoperative data on histology, MRI and CA-125 levels were available for 292 patients. The sensitivity and specificity of combined preoperative assessment to discriminate between low- and non-low risk EC patients according to ESMO-ESTRO-ESGO criteria were 96.1% and 73.6% respectively. AUC of the corresponding ROC curve was 0.849. False negative rate was 3.8% (9/235). Among the 9 patients falsely classified as low-risk, one patient had nodal metastasis (1/9, 11.1%) after full staging. CONCLUSION A selective LND strategy for EC patients based on preoperative assessment is possible and would probably be cost-effective, while not jeopardizing patients' survival or patient quality of life (QoL).

Abstract
Endometrial cancer (EC) in postmenopausal women is usually associated with abnormal vaginal bleeding. However, asymptomatic cases of EC have been reported. The incidence of EC has been estimated to 1.3-3.05 per 1,000 screened postmenopausal asymptomatic women, the most significant ultra-sonographic feature being the thickened endometrium. We reviewed the literature on the accuracy of endometrial thickness measurement by transvaginal sonography (TVS) in predicting EC in asymptomatic postmenopausal women. The use of endometrial thickness as a sole screening test was found not to be of high predictive value and it should be combined with the evaluation of EC risk factors and followed by hysteroscopy and biopsy in suspicious cases. The lack of a universal cut-off value for endometrial thickness that could be correlated to EC is pointed out.

Abstract
INTRODUCTION We undertook a prospective cohort study to compare the effectiveness and safety of 50 µg misoprostol versus 3 mg dinoprostone in two vaginal doses 6 hours apart, followed if necessary by oxytocin for labor induction in low-risk post-term (> 40 weeks) pregnancies with unfavorable cervix (Bishop score ≤ 6). METHODS Labor induction and subsequent management were conducted using a standardized protocol. The primary outcome of the study was labor induction rate. Secondary outcomes included mode of delivery, time interval from induction to delivery, maternal complications and neonatal outcome. RESULTS 107 patients received misoprostol (Group A) and 99 patients received dinoprostone (Group B). Compared with group A, more women in Group B needed a second vaginal dose of prostaglandin or oxytocin infusion in order to proceed to labor (21.5 vs. 43.4 %; p = 0.01). Misoprostol alone as a single or double vaginal dose was more effective than dinoprostone alone in inducing labor without oxytocin administration (85.0 vs. 50.4 %; p = 0.04). Overall, the rate of successful induction of labor did not differ between groups (91.6 vs. 85.8 %; p = 0.75). Vaginal delivery, operative vaginal delivery and Caesarean section rates were not significantly different. Time interval from induction to delivery however, was shorter for Group A (median 11 hours vs. 14.1 hours; p < 0.001). Though emergency Caesarean section due to fetal distress was more frequent in Group A (16.8 vs. 4.0 %; p = 0.007), low Apgar scores < 7 and NICU admissions did not differ significantly. Maternal complications, mostly not serious, were higher in Group A (31.8 vs. 2.0, p < 0.001). CONCLUSION Misoprostol is a more effective agent than dinoprost in post-term pregnancy for labor induction with few maternal adverse effects.

Abstract
Amelanotic malignant melanoma of the vulva is extremely rare. The authors describe here a case of amelanotic malignant melanoma of the vulva, occurring in a 71-year-old woman without any clinical symptoms. The woman had a small nodular lesion in the left labia majora. Local excision was performed. Histological examination revealed an in situ malignant melanoma without any evidence of invasive disease. All suspicious lesions in the vulva region, even if there are no clinical symptoms, should be biopsied, and if an in-situ melanoma is identified, partial or total vulvectomy should be considered.

Abstract
Purpose: Despite the widespread screening programs, cervical cancer remains the third most common cancer in developing countries. Based on the implementation of cervical screening programs with the referred adoption of improved screening methods in cervical cytology with the knowledge of the important role of the human papilloma virus (HPV) it's incidence is decreased in the developed world. Even if cervical HPV infection is incredibly common, cervical cancer is relatively rare. Depending on the rarity of invasive disease and the improvement of detection of pre-cancerous lesions due to the participation in screening programs, the goal of screening is to detect the cervical lesions early in order to be treated before cancer is developed. In populations with many preventive screening programs, a decrease in cervical cancer mortality of 50-75% is mentioned over the past 50 years. The preventive examination of vagina and cervix smear, Pap test, and the HPV DNA test are remarkable diagnostic tools according to the American Cancer Association guidelines, in the investigation of asymptomatic women and in the follow up of women after the treatment of pre-invasive cervical cancer. The treatment of cervical cancer is based on the FIGO 2009 cervical cancer staging.

Abstract
Brenner tumours of the ovary are uncommon neoplasms and mostly benign. There is general agreement that Brenner tumors are derived from the surface epithelium of the ovary or the pelvic mesothelium through transitional cell metaplasia. It is essential to categorise these tumours as benign, borderline or malignant type as the biologic behaviour and choice of surgery differs in all of the three categories. The authors report a case of Brenner tumour that had only a single area with a beginning indistinct stroma vessel invasion. However the presence of characteristic epithelial nests, fibromatous stroma, and marked cytological metaplasia without atypia provided important clues to the correct diagnosis--proof of a benign tumour.

Abstract
OBJECTIVE The object of this study was to investigate the efficacy of vaginal administration of misoprostol versus dinoprostone in neonatal outcome. MATERIALS AND METHODS The first Group A included 77 pregnant women, who requested pregnancy termination one week after labour term and received vaginally misoprostol 50 µg, while the other 69 pregnant women in Group B were vaginally administrated three mg dinoprostone. According to the authors' protocol this procedure was repeated after six hours for a maximum of two times. RESULTS The labour duration was longer in Group B (p = 0.000), while the APGAR score was better in Group A (p = 0.015). In Group A the labour modus was as follows: 86.9% normal vaginal labour, 3.8% vacuum extraction, and 9.3% cesarean section, while in Group B it was 82.83% normal vaginal labour, 3.07% vacuum extraction, and 14.1% cesarean section. CONCLUSION Misoprostol has advantages according to neonatal outcome compared to administration of dinoprostone.

Abstract
RATIONALE To elucidate the prepubertal risk factors associated with the development of Polycystic Ovary Syndrome (PCOS) and determine the special clinical manifestations of the syndrome in this transitional time of a woman's life. OBJECTIVE To propose therapeutic targets and regimens, not only to prevent the long-term complications of the syndrome, but also to improve the self-esteem of a young girl who matures into womanhood. METHODS AND RESULTS A systematic review of literature was performed through electronic database searches (Pubmed, Medline and Embase). Studies published in English-language, peer-reviewed journals from 1996 to 2013 were included. The selected studies focused on the risk factors, the unique features and treatment options of the PCOS in puberty. The pathogenesis of the PCOS was hypothesized to be based on interactions between genetic and certain environmental factors. The diagnosis was usually difficult in young girls. The syndrome was related to a greater risk of future infertility, type II diabetes mellitus, the metabolic syndrome and cardiovascular disease. Early treatment was crucial to prevent the long-term complications of the syndrome, especially infertility and cardiovascular disease. DISCUSSION The recognition of the early signs of PCOS during or even before adolescence is of great importance. It is essential to establish the correct diagnosis for PCOS and rule out other causes of androgen excess in young women with hyperandrogenism. The type of treatment applied should be considered on an individual basis. ABBREVIATIONS PCOS = Polycystic Ovary Syndrome.

Abstract
Ballantyne's syndrome, the combination of maternal generalized edema and fetal ascites, is rare and alarming in gestation. Early diagnosis might be useful in providing proper management of the fetus and aiming at an improved clinical result. The syndrome is an indication that HF is there, it has already started expanding the fetal torso and endangering the child-bearer's life. Despite the detailed investigation, no apparent cause for the emergence of the hydrops was identified.

Abstract
OBJECTIVE The effectiveness of pelvic and para-aortic lymphadenectomy in the morbidity of patients affected by early-stage endometrial carcinoma (EC) is the subject of this study. STUDY DESIGN Ninety-two cases with endometrial cancer that underwent para-aortic and pelvic lymphadenectomy, from June 1995 to June 2006, were studied and compared with 30 cases of patients with endometrial cancer without lymphadenectomy. RESULTS According to the results, systematic pelvic and para-aortic lymphadenectomies improved disease-free and overall survival rates among the patients with endometrial cancer. The mean number of removed para-aortic lymph nodes was 19.01 +/- 5.88, whereas the mean number of removed iliac lymph nodes was 32.94 +/- 6.69. Forty-two and 31 metastatic iliac and para-aortic nodes were found, respectively. No surgery-related deaths and major intraoperative injuries occurred. The frequency and the type of postoperative complications were not affected by the performance of lymphadenectomy. The morbidity rate was 6.2%, similar to the group without lymphadenectomy (5.79%). No recurrence occurred in the group with lymphadenectomy, while in the other group the recurrence rate was 23.3%. CONCLUSIONS Lymph nodes metastases can be observed in early stages of EC. Pelvic and para-aortic lymphadenectomies seems to provide profound information about the Stage of the disease and the patient's survival, identifying which patients are suitable for supplementary treatment, without significant clinical increase of morbidity.

Abstract
PURPOSE To detect the incidence of CMV infection in spontaneous abortion in Thrace. METHODS Genetic material from 143 fetuses aged from 11 to 39 weeks was examined. The material originated from various regions of Thrace. All fetuses and the respective placentas underwent routine histopathology. DNA was isolated from sections of paraffinized tissues. Detection of CMV in the DNA genomic samples was performed using a commercial PCR-based detection kit. RESULTS From the 143 fetuses that were examined, two were found to be CMV positive. Pathological findings related to inflammatory corruptions were observed in the placentas of 97 embryos, including the CMV infected ones. CONCLUSIONS This study indicates CMV-DNA infection in 1.4% of aborted fetuses. CMV infection incidence in aborted fetuses is similar to this reported in other European regions. The molecular technique of PCR applied on paraffin-embedded biopsy material is proven to be an accurate, valid and fast method for investigating the CMV infection in aborted fetuses.

Abstract
BACKGROUND Trisomy 16 is a very frequent autosomal anomaly accounting for about 2% of first trimester abortions. In most pregnancies the chromosomal genome found in the fetus is also present in the placenta. Confined placental mosaicism is frequently detected in the placental region along with a structurally normal fetus. CASE We present the case of a 39-year-old primigravida with confined placental mosaicism diagnosed with chorionic villus sampling. Amniocentesis showed a normal karyotype (46, XX). Detailed scanning revealed no structural fetal anomalies, but severe oligohydramnios. CONCLUSION Diagnosis of trisomy 16 does not necessarily mean that the newborn has anatomical abnormalities.

Abstract
BACKGROUND Borderline ovarian tumors account for 15-20% of all ovarian epithelial tumors. Since their original description in 1929, our knowledge of their natural history and molecular pathology has advanced most dramatically over the last two decades. This improved knowledge of BOT has permitted to drastically decrease the therapeutics of these tumors, which remains mostly surgical. METHOD We studied the available literature on surgical management of BOT accentuating the most important aspects on this topic: radical vs. conservative treatment, fertility preservation. RESULTS Although there are conflicting reports about some of the aspects of surgical management of these tumors, since BOTs commonly affect women of reproductive age, who have not completed childbearing, have an excellent overall prognosis and the majority of them (approximately 50% to 85%) are stage I at diagnosis, conservative surgery (unilateral salpingo-oophorectomy or cystectomy) can be safely performed after comprehensive surgical staging, in order to preserve fertility. CONCLUSION Conservative surgery could be safely performed in young patients treated for BOT, provided that they are carefully followed-up.

Abstract
Introduction: Peritoneal washing cytology and imprint cytology of pelvic lymph nodes samples were used to evaluate the rapid cytologic detection of peritoneal and retroperitoneal spread of endometrial cancer. Materials and Methods: We undertook a study on 194 endometrial cancer patients who underwent primary treatment in the Gynecologic Clinic, Democritus University of Thrace. All patients were subjected to peritoneal washing (PW) cytology and imprint cytology performed on lymph node sampling. The cytologic specimens were stained by May-Grünwald Giemsa (MGG) and Haematoxylin eosin (HE) techniques. Cell-blocks prepared from peritoneal washings (PWs) and the lymph node samples were sent for histologic examination. The cytologic findings were correlated to histologic results. Results: Rapid intraoperative cytology provides a useful diagnostic technique for the assessment of endometrial cancer spread. HE and MGG stain presented different values of sensitivity and specificity in the detection of peritoneal and retroperitoneal spread of endometrial cancer. Conclusion: Cytologic assessment of intraperitoneal and retroperitoneal spread of endometrial cancer is a rapid, intraoperative procedure, which provides the surgeon with useful information regarding the stage of the disease and the subsequent therapeutic approach.

Abstract
OBJECTIVE We measured first trimester plasma leptin concentrations in 37 women who subsequently developed pre-eclampsia and 53 normotensive controls to determine the interrelation between leptin and body mass index (BMI) in both groups. We further investigated the association between the risks for pre-eclampsia with maternal leptin levels. METHODS Bloods samples were collected at 13 weeks. Non-parametric tests, Spearman's correlation, linear regression analysis and multiple logistic regression analysis were applied in our data. RESULTS 1 kg/m(2) increase in pre-pregnancy BMI was related to a 2.747 (95% CI: 3.242-2.252) ng/ml rise in leptin concentration among cases and 2.502 (95% CI: 2.873-2.131) ng/ml rise in leptin concentrations among controls. Increased leptin concentration (>or=25.3 ng/ml ) in lean women is associated with a 18.8-fold increased risk of pre-eclampsia (adjusted OR: 18.8, CI: 1.8-194, p = 0.014 ). Leptin treated as a continuous variable is a significant predictor of pre-eclampsia (adjusted OR: 1.08, CI: 1.018-1.133, p = 0.009). CONCLUSION Increased leptin concentration can definitely contribute to the prediction of pre-eclampsia in lean women, but this is not the case in overweight women. Further research in terms of longitudinal case-control studies is required to clarify the predictive value of pre-eclampsia.

Abstract
OBJECTIVE To determine the connection between maternal first trimester serum leptin levels and newborn weight. METHODS The study included 37 preeclamptic women and 53 normotensive women who considered the control group. Maternal blood samples were withdrawn at 13 weeks of gestation for the measurement of leptin concentrations. Birth weights were transformed to z-scores according to maternal and obstetrical features, based on customized centiles. Non-parametric tests, student's t-test, Pearson's correlation, Spearman's correlation and linear regression analysis were performed in our analysis. RESULTS Pre-pregnancy body mass index and first trimester maternal plasma leptin levels were significantly higher among women with preeclampsia (p=0.015 and p<0.001, respectively). Birth weight z-score was negatively correlated with leptin levels (r= -0.570, p<0.001), in preeclamptic group and in control group (r= -0.477, p<0.001). The regression modelling demonstrated a significant negative association between birth weight z-scores and leptin for both groups. CONCLUSION Maternal first trimester serum leptin demonstrates a significant negative association with neonatal weight in preeclamptic pregnancies and to a lesser extent in normotensive pregnancies. A possible leptin's involvement in pathophysiological adaptations that define the foetal growth potential can be supported.

Abstract
Vascular endothelial growth factor (VEGF) is a major angiogenic factor and prime regulator of endothelial cell proliferation. During pregnancy, VEGF is essential for the proliferation of trophoblasts, the development of embryonic vasculature and the growth of maternal and fetal blood cells in utero. In cases of pre-eclampsia and in some circumstances of preterm labor-raised umbilical cord serum, VEGF levels might be correlated with the clinical development of the above pathological disorders. Genetic alteration as 936C/T VEGF gene polymorphism has a statistical significant correlation with the severity of pre-eclampsia. The same VEGF gene polymorphism, which has been associated with lower protein production, has an increased risk of spontaneous preterm delivery in a Greek-studied population. Homozygotes were found to carry the greatest risk with a lesser proportionate risk associated with heterozygosity, whereas women with the -1154 allele of the VEGF gene have an increased risk of recurrent pregnancy loss. In this review, we present evidence that demonstrates an implication of VEGF gene polymorphisms in the pathological disorders of pregnancy. However, further genetic studies are needed to confirm these data.
