RESUMO

OBJECTIVE: To assess the feasibility and results of introducing a policy of universal screening for preterm delivery (PTD) by mid-trimester cervical-length (CL) measurement. METHODS: In this retrospective cross-sectional study of singleton pregnancies, transvaginal sonography for CL measurement was performed at 20-24 weeks of gestation. Vaginal progesterone therapy was offered to women with CL ≤ 15 mm. The incidence of spontaneous PTD (sPTD) according to CL and the distribution of CL measurements were assessed. Rate of PTD before implementation of screening was compared with that after. RESULTS: A total of 10 506 singleton pregnancies were assessed. The decline rate was 1.32%. sPTD < 32 weeks, < 34 weeks and < 37 weeks occurred in 0.51%, 0.82% and 3.90% of pregnancies, respectively. CL measurement was best described by a mixture model distribution comprising a 'short' and a 'long' component. The percentage of the two components varied between subgroups of PTD, with the short component being greater the earlier the birth. CL, history of miscarriage, smoking status and prior PTD were independent predictors in the construction of a model predictive of PTD < 34 weeks (area under the curve = 0.74, P < 0.001). The rate of sPTD < 34 weeks in women with CL ≤ 15 mm receiving progesterone treatment was 20.4%. In the progesterone-treated group, a plateau was observed in the increase in risk for PTD for CL 9-13 mm, whereas below 9 mm the risk increased exponentially. Following the introduction of mid-trimester CL measurement, there was a trend for reduction in the rate of any PTD < 34 weeks of about 20% in comparison with the prescreening period (odds ratio = 0.81; 95% CI, 0.59-1.13). CONCLUSIONS: Universal screening for PTD by transvaginal sonographic measurement of CL at 20-24 weeks is feasible and well accepted by pregnant women. This policy identifies a very high-risk group that may benefit from intervention. Copyright © 2018 ISUOG. Published by John Wiley & Sons Ltd.

RESUMO

PURPOSE: Delineate whereas ADAM-12 levels at first trimester of pregnancy may be used as a marker for hypertension-preeclampsia (PE) and intrauterine growth restriction (IUGR). MATERIALS AND METHODS: The present is a case control study. Serum ADAM-12 of women presenting for routine assessment of risk for chromosomal abnormalities at 11+0 to 13+6 weeks of gestation was measured. The study group comprised of 98 pregnancies that subsequently developed pregnancy-induced hypertension (PIH) or PE or small for gestational age fetuses (SGA), and were compared to 100 uncomplicated pregnancies. RESULTS: There was no statistically significant difference of mean log multiple of the expected median (MoM) of ADAM12 between control group and the group that consisted of all women with complicated pregnancy (PE, PIH, and SGA). ADAM-12 levels in women who developed PE during pregnancy were significantly lower than in womien of control group (mean log MoM: 0.109 vs 0.008, p = 0.010). Similarly, ADAM-12 levels in women who developed PE and/or PIH were significantly lower than in women of control group (mean log MoM: 0.066 vs 0.008, p = 0.015). There was no significant difference of ADAM12 levels between controls and pregnancies with SGA fetuses. CONCLUSION: Maternal serum levels of ADAM-12 at the first trimester are significantly lower in women who later develop PE when compared with women with uncomplicated pregnancies.

RESUMO

OBJECTIVE: Limited data exist concerning the presence of polycystic ovary syndrome (PCOS) in premenopausal women with nonalcoholic fatty liver disease (NAFLD). We aimed to investigate the prevalence of PCOS in overweight and obese premenopausal women with NAFLD. DESIGN: Prospective, observational, and cross-sectional study. METHODS: We studied 110 apparently healthy, overweight, and obese (BMI: 25.1-49.1 kg/m(2)) premenopausal women (age: 18-45 years) reporting no or minimal alcohol consumption for NAFLD with abdominal ultrasonography after excluding causes of secondary liver disease and for PCOS (Rotterdam criteria) with clinical examination, biochemical evaluation, and pelvic ultrasonography. Insulin resistance (IR) was assessed by homeostasis model assessment of IR (HOMA-IR), and free androgen index was calculated. RESULTS: NAFLD was detected in 71/110 women (64.5%). Women with NAFLD compared to women without NAFLD were more commonly diagnosed with PCOS (43.7% vs 23.1%, respectively, P=0.04), metabolic syndrome (30.2% vs 5.3%, respectively, P=0.003), and abnormal lipid profile (81.1% vs 51.3%, P=0.002). All women with abnormal glucose metabolism had NAFLD (P=0.01). Although PCOS was associated with NAFLD (OR 2.6, 95% CI: 1.1-6.2, P=0.04), in a multivariate analysis higher HOMA-IR values (OR 2.2, 95% CI: 1.1-4.4, P=0.02) and triglyceride levels (OR 1.01, 95% CI: 1.00-1.02, P=0.04) independently predicted NAFLD, after adjusting for age, BMI, and waist-to-hip ratio. CONCLUSIONS: These findings indicate an increased prevalence of PCOS in overweight and obese premenopausal women with NAFLD, although it is not supported that the syndrome is primarily involved in NAFLD. Evaluation for PCOS may be considered in these women.

RESUMO

Objective. To reevaluate the long-term effectiveness and safety of laparoscopy in benign ovarian pathology. Materials and Methods. 1522 women with benign adnexal cysts, laparoscopically treated in the 3rd Department of Ob/Gyn, General University hospital "Attikon" and "Lito" Maternity Hospital between July 1998 and December 2006, were included. Results. The diagnosis in 1222 (80,6%) cases was endometriosis of the ovary, 60 (4%) hydrosalpinx, 51 (3,3%) serous cystadenomas, 44 (2,9%) dermoid ovarian cyst, 38 (2,5%) borderline tumors, 35 (2,3%) unruptured follicles, and 33 (2,2%) paraovarian cysts. In 174 cases (11,5%) laparoscopy was converted to laparotomy due to technical difficulties or suspicion of cancer. In particular, laparotomy was performed in 119 (8%) women due to severe adhesions and 18 (1,2%) women due to bleeding that could not be controlled safely by laparoscopy. In 36 (2,4%) women frozen section during operation revealed malignancy and laparoscopy was converted to laparotomy. A few operative complications were recorded like post-op fever, small hematomas at the trocar entries. Conclusions. Laparoscopic surgery seems to offer significant advantages such as reduced hospital stay, less adverse effects, better quality of life, and superior vision especially on surgical treatment of cases like endometriosis.

RESUMO

Women with polycystic ovary syndrome (PCOS) are often characterized by adiposity and insulin resistance (IR). Recent studies in patients with obesity and diabetes mellitus type 2 (DMt2) indicate that adiponectin and resistin may play a role in the pathophysiology of IR. The aim of this study was to identify a possible correlation between the plasma levels of adiponectin and resistin and IR in patients with PCOS. Thirty-one women of reproductive age were enrolled in this prospective study after being diagnosed with PCOS and IR according to Rotterdam and American Diabetes Association (ADA) criteria, respectively. Every patient was treated with a daily dose of 1275 mg metformin for 6 months. Adiponectin, resistin, and the primary hormonal and metabolic parameters of the syndrome were evaluated at entry and endpoint of treatment. Adiponectin plasma levels were reduced after metformin treatment, but resistin levels were not significantly affected. Our study suggests that circulating levels of adiponectin should be evaluated with skepticism in patients with PCOS. The adipokine's role in the manifestation of IR in PCOS remains unclear and needs further investigation.

RESUMO

OBJECTIVES: To examine the distribution of cervical length (CL) in the late second and third trimesters of pregnancy and construct survival models for spontaneous delivery. METHODS: This cross-sectional study included 647 women with a singleton pregnancy who had routine CL measurements taken by transvaginal ultrasonography between 24 and 40 weeks' gestation. Only one measurement per patient was included in the analysis. Exploratory data analysis revealed that the distribution of CL measurements was a mixture of two Gaussian distributions, and subsequently a mixture model was applied to describe the distribution of CL. Changes in CL in relation to gestational age were examined by regression analysis and measurements were converted to Z-scores. Survival analysis was applied to the subgroups identified, to describe the probability of delivery throughout gestation. RESULTS: CL was best described by a mixture model of two subgroups with Gaussian distribution, one including women with a long cervix (73.85% of the study population, mean CL of 28.2 ± 4.45 mm) and the other including women with a short cervix (26.15% of the study population, mean CL of 12.3 ± 5.14 mm). CL was dependent on gestational age (GA), therefore conversion to Z-scores was employed in the analysis. Women with a short cervix had a higher probability for spontaneous delivery (hazard ratio (HR), 1.807; P < 0.001) than did women with a long cervix, after adjustment for GA at the time of measurement (GA HR, 1.115; P < 0.001). In both subgroups, the probability of spontaneous delivery was predicted by the GA and CL Z-scores. Survival models for the prediction of spontaneous delivery were constructed separately for the short-cervix subgroup (GA HR, 1.085; P < 0.001 and CL Z-score HR, 0.819; P = 0.003) and the long-cervix subgroup (GA HR, 1.130; P < 0.001 and CL Z-score HR, 0.864; P = 0.005). CONCLUSIONS: CL follows a mixture of two Gaussian distributions, one for a short and one for a long cervix. Late second-trimester/third-trimester CL measurement may be of value in estimating the probability for spontaneous delivery at any given gestational age.

RESUMO

PURPOSE OF INVESTIGATION: The aim of the present study was to record how the treatment of female cancer may affect sexuality and interpersonal relations in the couple. MATERIAL AND METHODS: From September 2008 until February 2012, the authors prospectively studied 67 patients with breast cancer (Group A) and 43 with gynecological cancers (Group B). As control groups 33 patients with benign breast and 30 patients with benign gynecological lesions (group 0a and 0b respectively) were used. Sexuality and interpersonal relations were evaluated by a questionnaire. The authors also evaluated interpersonal relations focusing on sexual function at the time of diagnosis and a year after the initial treatment for cancer. RESULTS: A significant reduction of the "sexual desire", "sexual Arousal", and "orgasm" dimension was found in both cancer groups, in contrast to the control group, revealing no significant change. The "sexual enjoyment" scale was significantly decreased in gynecological cancer group but not in breast cancer group. While the score on the "relationship quality" dimension significantly increased in both cancer groups. In all groups, there was a significantly positive correlation between sexual function and enjoyment; on the contrary, there was a significantly negative correlation between relationship quality and sexual function and enjoyment. CONCLUSION: Sexual dysfunctions is a clinical problem which should be evidenced at the beginning of therapy, from the oncologists in order to provide integrated treatment to their patients.

RESUMO

Reactive Oxygen Species (ROS) are produced as a normal product of aerobic metabolism. Naturally, there is an array of protective mechanisms that neutralize ROS, while any potential imbalance between ROS and antioxidants results in oxidative stress. In an In Vitro Fertilization (IVF) setting, existing literature suggests a favorable outcome in terms of oocyte quality/maturation and fertilization rate with increased ROS levels, while other study groups have presented significant data on the detrimental effect of increased ROS concentration in the quality of embryos exposed and their potential to advance. In this study, we examine the conflicting views of the role of ROS in fertilization and embryo quality, especially through their concentration in the follicular fluid of subfertile women undergoing IVF. The current debate could possibly be attributed to the different assay methods and end-point outcomes employed by each research group, along with the noted limited number of the relevant studies published on the subject. Properly conducted studies can further validate and elicit the exact role of ROS as well as their association to female reproduction, and especially to women undergoing IVF.

RESUMO

BACKGROUND: Hormone therapy (HT) is the treatment of choice for the alleviation of menopausal symptoms; concerns, however, about its concomitant long-term health risks have limited its use. DT56a is a unique enzymatic isolate of soybeans. The purpose of our study was to evaluate the efficacy and safety of DT56a, compared to HT, in symptomatic post-menopausal women. SUBJECTS AND METHODS: Eighty-nine post-menopausal women were studied prospectively. Women with climacteric symptoms were randomly assigned to receive eitherDT56a (no.=27) or oral low dose continuous combined HT (no.=26). Symptomatic women not wishing to receive any treatment served as controls (no.=36). Menopausal symptoms as assessed through the Kupperman index, serum lipids and lipoproteins, calcium, as well as bone mineral density (BMD), endometrial thickness, and mammography were assessed at baseline and at 12 months. RESULTS: Patients receiving HT and DT56a showed a significant and independent decrease in menopausal symptoms (mean difference in Kupperman score, DT56a group: -3.98, HT group -5.601, no treatment group +1.76, p-value <0.001). Lumbar spine BMD T-score was significantly lower in women receiving no treatment, as opposed to the two treatment arms which showed no significant change (No treatment, baseline: -0.60, final: -0.85, p=0.001; HT, baseline: -84, final -0.99, p=0.79; DT56a, baseline -0.51, final: -0.76, p=0.75). No differences in femoral bone density, ET or mammography classification were detected in any of the treatment arms. Likewise, serum lipids or lipoproteins did not differ between the three groups. CONCLUSIONS: DT56a decreased menopausal symptoms significantly and in the same degree as HT.

RESUMO

AIM: To determine the prevalence and frequency of non classical congenital adrenal hyperplasia (NC-CAH) due to 21-OHD at the time of clinical presentation and at the peripubertal period in a substantial sample of Greek women with acne and to investigate the correlation of serum T, 17-OHP and DHEA-S with acne appearance at the time of clinical presentation. METHODS: One hundred and twenty-three unselected women with hyperandrogenemic symptoms were examined. After the ACTH stimulation test, 6 (4.9%) women were diagnosed with NC-CAH due to 21-OHD. RESULTS: There was not any statistical significant difference in the frequency of peripubertal acne between NC-CAH group of patients (6.4%) and patients with hyperandrogenemia of other aetiology (93%), mainly ovarian (P = 0.41). However, there was a statistical significant difference in the prevalence of acne at the time of clinical examination between the two groups (P = 0.04). Acne was present in 83.3% of women with NC-CAH vs. 41.02% of women in the hyperandrogenic group without NC-CAH. A statistically significant decrease of acne from the peripubertal time to the time of clinical examination in the group of women with hyperandrogenemia of other aetiology (-21.37%) was observed compared to women with NC-CAH (P < 0.001). CONCLUSION: We have shown that acne persists from peripubertal period to adult life in NC-CAH women whereas it tends to diminish in women with hyperandrogenemia of other aetiology. Acne is a prominent finding in women with NC-CAH. Serum concentrations of 17-OHP after ACTH stimulation (17-OHP6O ) should be investigated in women with persistent acne in adult life.

RESUMO

OBJECTIVE: Recently, it has been debated whether the new polycystic ovary syndrome (PCOS) phenotypes, according to the Rotterdam criteria, share the same metabolic risk with the classic ones (National Institutes of Health 1990). Our study sought to compare the prevalence of metabolic syndrome (MS) and glucose homeostasis disorders in Greek women with classic and new PCOS phenotypes. MATERIALS AND METHODS: Two hundred and sixty-six Greek PCOS women were recruited and divided into groups according to two of the three Rotterdam criteria that they fulfilled. Two subgroups were formed; the first represented the classic phenotypes and the second the new phenotypes. The clinical, biochemical, and ultrasound characteristics of both groups were explored. All subjects were evaluated for MS and underwent a 2-h glucose tolerance test to assess insulin resistance (IR) as measured by the homeostasis model assessment (HOMA-IR), quantitative insulin sensitivity check index (QUICKI), and MATSUDA indices. RESULTS: 62.4% of PCOS women were classified as classic NIH phenotypes of which 32 women had MS (prevalence 19.6%). Only 4 patients categorized in the newer phenotypic groups had MS (prevalence 4.1%). Among the subjects with classic phenotypes, 11.7% exhibited impaired glucose tolerance (3-fold higher percentage compared to patients with newer phenotypes). Regarding IR indices, HOMA-IR was significantly higher and QUICKI significantly lower for classic phenotypes. CONCLUSIONS: Greek PCOS women with classic phenotypes are at increased risk for MS and impaired glucose homeostasis compared to women with newer phenotypes. A subclassification of PCOS permits the earlier recognition and closer surveillance of women whose metabolic profile indicates potential risks for adverse health outcomes.

RESUMO

There are little systematic data reported in the literature on complications observed after transvaginal oocyte retrieval (OR) guided by ultrasound. We report our experience in 542 in vitro fertilisation cycles. The frequency of severe complications in our patients was 0.72%; of these, two cases were bronchospasm during anaesthesia (0.36%) and two were cases of intraperitoneal bleeding (0.36%); minor vaginal bleeding was the most frequent complication (18.08%), which was treated easily. Through this retrospective analysis, it is evident that clinical suspicion is of particular importance in detecting post-OR complications on one hand, but on the other these complications are rare and most are treated conservatively.

RESUMO

OBJECTIVES: To assess the performance of third-trimester fetal biometry and fetal Doppler studies for the prediction of small-for-gestational-age (SGA) neonates, and to explore contingency strategies using a first-trimester prediction model based on maternal and fetal parameters and third-trimester ultrasound. METHODS: This was an observational cross-sectional study of uncomplicated singleton pregnancies. Risk assessment for chromosomal abnormality was carried out in 4702 pregnancies using a combination of ultrasound markers (fetal nuchal translucency thickness (NT) and nasal bone assessment) and biochemistry (free beta-human chorionic gonadotropin (ß-hCG) and pregnancy-associated plasma protein-A (PAPP-A)) at 11 to 13 + 6 weeks. Maternal demographic characteristics and method of conception were recorded. Third-trimester (30-34 weeks) fetal biometry (biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC) and femur length (FL)) and umbilical artery (UA) and middle cerebral artery Doppler studies were performed routinely in a subgroup (n = 2310). Reference ranges for birth weight were constructed using the cohort of 4702 women, and neonates were classified as small (SGA, ≤ 5th centile) or appropriate (AGA) for gestational age. First-trimester, third-trimester and integrated first- and third-trimester prediction models for SGA were constructed using regression analysis and three different contingency strategies of rescanning in the third trimester were investigated. RESULTS: According to the areas under the receiver-operating characteristics curves (AUCs), AC (AUC = 0.85) and ultrasound-estimated fetal weight (EFW, AUC = 0.87) were equally good predictors of SGA. The model was marginally improved by the addition of UA Doppler, smoking status and first-trimester indices (free ß-hCG and PAPP-A multiples of the median) (combined model, AUC = 0.88), but the difference was not statistically significant. A contingency strategy of rescanning 50% of the population in the third trimester according to the risk estimated by a first-trimester prediction model yielded a detection rate of 79% for a 25% screen-positive rate. CONCLUSION: Third-trimester ultrasound is effective in screening for SGA in uncomplicated pregnancies. The use of a contingency screening policy can reduce the need for unnecessary examinations.

RESUMO

OBJECTIVE: To measure the intracranial translucency (IT) and the cisterna magna (CM), to produce reference ranges and to examine the interobserver and intraobserver variability of those measurements. To examine the possible association of IT with chromosomal abnormalities. METHODS: Prospective study on pregnancies assessed at 11 to 14 weeks. IT was measured retrospectively in 17 cases with aneuploidy. RESULTS: To produce reference ranges, 465 fetuses were used. IT and CM correlated linearly with crown-rump-length (CRL) and were independent of maternal demographic characteristics and biochemical indices. IT had a weak positive correlation with nuchal translucency. For IT the intraclass correlation coefficient was 0.88 for intraobserver variability and 0.83 for interobserver variability. For CM the intraclass correlation coefficient was 0.95 for intraobserver variability and 0.84 for interobserver variability. The IT multiple of the median was significantly increased in the chromosomally abnormal fetuses (1.02 for the normal and 1.28 for the chromosomally abnormal fetuses, Mann Whitney p < 0.001). IT multiple of the median was a significant predictor of chromosomal abnormality (Receiver Operator Characteristic curve analysis: Area under the curve = 0.86, CI=0.76-0.96, p<0.001). CONCLUSION: Intracranial translucency and CM can be measured reliably at the 11 to 14 weeks examination and the measurements are highly reproducible. IT appears to be increased in fetuses with chromosomal abnormalities.

RESUMO

The molecular epidemiology of human papillomavirus (HPV) infection in a sample of Greek women (n = 2952, mean age 42.2 ± 13.3 years) was examined. HPV prevalence was 50.7% (95% confidence interval, 48.8-52.6). The most frequent HPV types were HPV 53, 51 and 66 (10.2%, 9.4% and 9.3%, respectively). HPV positivity was associated with age, age of sexual debut, number of sexual partners and duration of sexual relationship, while marriage or multiparity protected against infection (all p <0.001). Follow-up of this cohort will assist in predicting the effect of vaccination with the new HPV vaccines on future screening with HPV-based tests for cervical cancer.

RESUMO

BACKGROUND: The detection of high-grade cervical intraepithelial neoplasia (CIN2 or worse) among patients with low-grade cytology (LSIL) is challenging. The aim of this study was to assess the efficacy of p16(INK4a) in the risk assessment of women with LSIL cytology. METHODS: Consecutive liquid-based cytology specimens of 95 LSIL smears were selected and stained for p16(INK4a). All patients had colposcopically directed punch biopsies or large loop excision of the transformation zone of the cervix. The endpoint was detection of a biopsy-confirmed CIN2 or worse. RESULTS: The overall sensitivity and specificity of p16(INK4a) for diagnosis of CIN2+ among LSIL smears were 41% and 86%, respectively. The positive predictive value of the biomarker was 62% and the negative predictive value 72%. CONCLUSIONS: The study shows that p16(INK4a) has low sensitivity but acceptable specificity for evaluation of LSIL smears harbouring high-grade lesions. The marker needs to be further assessed as an adjunct to other tests in an attempt to improve the triage of LSIL cytology smears.

RESUMO

OBJECTIVES: To develop a model for the prediction of short cervix ( ≤ 15 mm) at 20-24 weeks by combining maternal history and transvaginal ultrasonographic measurement of cervical length at 11-14 weeks. To explore the value of an additional ultrasound examination of the cervix at about 17 weeks. METHODS: Longitudinal prospective study in 800 unselected pregnant women presenting for first-trimester ultrasound assessment by nuchal translucency and serum biochemistry. Cervical length was evaluated transvaginally between 11 weeks and 13 weeks and 6 days (cx1), at 16-19 weeks (cx2) and 20-24 weeks (cx3). Backward multiple logistic regression analysis with cx3 ≤ 15 mm as the dependent variable was used to identify the predictors of a short cervix at 20-24 weeks. RESULTS: Cx1 and history of preterm delivery were significant independent contributors of a short cervix at 20-24 weeks [area under the curve (AUC 0.808, p < 0.001, Model) 1]. Furthermore, the cx1/cx2 ratio was a significant independent predictor of a short cervix at 20-24 weeks (odds ratio = 58.325 p = 0.012). The addition of the cx1/cx2 ratio improved the model (AUC = 0.878, p < 0.001, Model 2). CONCLUSIONS: A short cervix at 20-24 weeks can be predicted at the 11-14 weeks scan. The addition of a cervical measurement at about 17 weeks can improve the prediction model.

RESUMO

OBJECTIVE: To determine how the proportion of the cervical volume excised affects cervical regeneration. DESIGN: Prospective observational study. SETTING: University Hospital. POPULATION: Women planning to undergo excisional treatment for cervical intraepithelial neoplasia who wish to have future pregnancies. METHODS: The cervical volume (and dimensions) is calculated with magnetic resonance imaging (MRI) before treatment. The volume (and dimensions) of the cone is assessed before fixation by a volumetric tube and a ruler; the percentage (%) of excision is computed. Cervical regeneration is estimated by repeat MRI at 6 months. MAIN OUTCOME MEASURES: Cervical regeneration in relation to proportion of excision. Statistical analysis was performed by box plots and analysis of variance. RESULTS: A total of 48 women have been recruited; 29 have completed 6 months follow up. Both the total cervical volume (from MRI) before treatment and the volume of the excised/ablated cone varied substantially. The estimated proportion of excision varied significantly between 4% and 39% (median 11%). Multivariate linear regression revealed that the proportional deficit at 6 months post-treatment was determined mainly by the proportion of the excised volume. CONCLUSIONS: Careful assessment of risks and benefits of treatment is essential when deciding to treat women who wish to have future pregnancies. Assessment of the proportion of the cervical volume and length excised might identify those that need further surveillance during future pregnancy.
