RESUMO
The aim of this study is to evaluate the relationship between three-dimensional (3D) ultrasound measurements of placenta at 11-13(6) weeks' gestation and maternal serum levels of pregnancy associated plasma protein-A (PAPP-A), free beta human chorionic gonadotrophin (fßhCG), Doppler parameters in early pregnancy. This prospective study consisted of 334 singleton pregnancies at 11-13(6) weeks' gestation. Placental volume and placental volumetric mean grey values were evaluated. The placental volume (cm(3)) was analysed using the Virtual Organ Computer-aided AnaLysis (VOCAL) imaging program and 3D histogram was used to calculate the volumetric mean grey value (%). Mean maternal age was 28.35 ± 7.55. Mean gestational age was 12.29 ± 0.68 weeks. Placental volume was 77.04 ± 35.74 cm(3). Mean grey value of the placenta was 34.38 ± 8.02%. Correlation analysis revealed that placental volume was significantly correlated with the crown-rump length (r = 0.173, p = 0.002), gestational week (r = 0.116, p = 0.036), ductus venosus pulsatility index (r = -0.101, p = 0.04) and maternal weight (r = 0.099, p = 0.037). There was a significant relation between the mean grey value of the placenta and maternal age (r = 0.131, p = 0.02), nuchal translucency (r = -0.109, p = 0.048), PAPP-A (r = 0.108, p = 0.04) and fßhCG (r = 0.104, p = 0.042). Volumetry of the placenta can be carried out with a high percentage of 1st trimester pregnancies. Volumetry during the 1st trimester could be helpful because of the less advanced state of placentation. This examination is easy to perform and the measurements can be acquired correctly and quickly.

We aimed to evaluate the volumetric and echogenic alterations in placentas between the intrauterine growth restriction (IUGR) and normal pregnancies using three-dimensional ultrasound and virtual organ computer-aided analysis (VOCAL) software. This case-control prospective study consisted of 48 singleton pregnancies complicated by IUGR and 60 healthy singleton pregnancies matched for maternal age, gestational age and parity. Placental volume (PV) and placental volumetric mean grey values (MGV) were evaluated. PV (cm(3)) was analysed using the VOCAL imaging analysis program, and 3D histogram was used to calculate the volumetric MGV (%). PV was 278.50 ± 63.68 and 370.98 ± 97.82 cm(3) in IUGR and control groups, respectively (p = 0.004). MGV of the placenta was 38.24 ± 8.41 and 38.24 ± 8.41 in IUGR and control groups, respectively (p = 0.30). receiver operator curve (ROC) curve analysis revealed that area under curve was 0.731 for PV. Correlation analysis revealed that PV was significantly associated with estimated fetal weight (r = 0.319, p = 0.003), biparietal diameter (r = 0.346, p = 0.002), head circumference (r = 0.269, p = 0.019), abdominal circumference (r = 0.344, p = 0.002) and femur length (r = 0.328, p = 0.004). PV was inversely related to the umbilical artery pulsatility index (r = - 0.244, p = 0.017). To the best of our knowledge, this is the first study evaluating volumetric MGV in IUGR placentas by comparing them with healthy pregnancies. Our study showed that PV diminishes significantly in IUGR pregnancies, whereas volumetric MGV does not alter significantly.

OBJECTIVE: To evaluate the outcomes and management options in pregnancies with early onset oligohydramnios. MATERIALS AND METHODS: The file datas of all pregnancies diagnosed as oligohydramnios or anhydramnios before 27 gestational weeks between January 2006 and September 2013 were evaluated retrospectively. The underlying pathology and associated anomalies, karyotype analysis, the outcome of the pregnancy (either termination or labour), and gestational week at the time of diagnosis were analyzed. RESULTS: A total of 54 pregnancies were evaluated; mean gestational week at the time of the diagnosis was 19.8 ± 4.6. Mean maternal age was 27.28 ± 6.03. Thirty-seven pregnancies were anhydramniotic, 13 fetuses had associated anomalies, five of them had multicyctic dysplastic kidney, five had bilateral renal agenesis, one had hypoplastic right heart syndrome, one had clubfoot, and one had ventricular septal defect and cleft palate. Karyotyping was normal regarding the fetuses with structural anomalies. Nineteen patients had premature preterm rupture of membranes and 39 patients had termination of pregnancy. CONCLUSION: The prognosis of early onset oligohydramnios is poor. Main determinant is gestational week at the time of the diagnosis.

AIM: The management of gynecological cancer patients mainly aims at prolonging survival but modern therapy focuses on good survival combined with a good quality of life (QoL). The aim of this study was to evaluate QoL and identify its associated factors in Turkish women with gynecologic cancer. METHOD: The study included 119 women diagnosed with endometrial, cervical, ovarian or vulvar cancer and treated at the Gynecologic Oncology Department of Celal Bayar University Faculty of Medicine. The data were collected between January and June 2011. QoL was measured with EORTC QLQ-C30 version 3.0. Relationships between clinical and socio- demographic characteristics and QoL scores were analyzed using the Mann-Whitney U, Kruskal Wallis and t-tests. RESULT: Global health status, physical and role function scores were found higher in women under the age of 60 years. Role function scores were found lower, and emotional and social scores were found to be higher in single women than in married women. Physical scores were found higher in women who had graduated from secondary school or above. Women with ovarian cancer had the highest while women with cervical cancer had the lowest global health score (65.3 ± 24.7 and 43.0 ± 24.1, respectively). Women with endometrial cancer were found to have better role function, and social well being than those with vulvar, cervical or ovarian cancer. Global, physical, role function, cognitive and social scores were found higher in women who had been treated with surgery. CONCLUSION: Gynecological cancer and treatment processes cause significant problems that have negative effects on physical, emotional, social and role function aspects of QoL. Health care providers play a key role in the identification and treatment of the complications of cancer therapy. Minimizing the effect of the symptoms of gynecologic cancer may positively impact on patient QoL.

AIM: The postmenopausal period is associated with increased risk for coronary atherosclerosis, and the effect of hormone replacement therapy in reducing this risk is controversial. Previous studies reported that nitric oxide synthetase (NOS) level might be important for the development of atherosclerosis, but no study has shown the interaction between hormone replacement therapy and endothelial NOS and inducible NOS intensity on coronary arteries yet. Our goal was to find out the immunostaining intensity of endothelial NOS and inducible NOS in ovariectomized rats which received oestradiol and norethisterone treatment. METHODS: We performed bilateral ovariectomy in 15, female, 90-day-old Wistar rats with an average weight of 250 grams. After waiting for 4 weeks for the menopausal state, they were divided into 3 groups to receive either placebo, 0.1 mg/day 17-beta-oestradiol (group E2), or 0.1 mg/day 17-beta-oestradiol + 0.1 mg/day norethisterone acetate (group E2-NETA) for 5 weeks. Another group included 5, normal, adult, female intact rats and served as controls. At the end of the treatment, all rats were sacrificed and coronary arteries were stained with inducible NOS and endothelial NOS polyclonal antibodies using streptavidin-biotin technique. RESULTS: The immunostaining of inducible NOS was prominent in perivascular connective tissue of the ovariectomized group but not in the control group. The inducible NOS immunostaining immunoreactivity was not detected in either treated groups. Immunostaining intensity of endothelial NOS did not differ in any 4 groups with similar staining. CONCLUSION: The present findings indicate that hormone replacement therapy down-regulates iNOS expression in coronary arteries of ovariectomized rats, and reduced iNOS may likely be involved in estrogen's beneficial effects.

The objective of the study was to determine the changes in the plasma activities of protein C and protein S that occur during normal pregnancy In this prospective cross-sectional study, plasma activities of protein C and protein S were measured in 32 normal pregnant women in the first, second and third trimester and 6 weeks after delivery There was a significant fall in protein C and protein S activities during normal pregnancy compared with the post-puerperal period. The activities of protein C and protein S also gradually decreased throughout pregnancy (p < 0.01). Increasing plasma volume during normal pregnancy and its dilutional effect might play some role in the low activities of protein S observed. The normal falls in protein S and protein C activities make it difficult to diagnose protein S and C deficiency during pregnancy. Based on our findings, if a woman has a thromboembolic event during pregnancy, testing for a definitive diagnosis of protein C or protein S deficiency or functional failure should be delayed until at least 6 weeks postpartum.

The aim of this study was to compare endometrial leukemia inhibitory factor (LIF) levels in spontaneous and clomiphene citrate (CC)-induced cycles of patients with unexplained infertility. The patients were followed in two consecutive cycles. Endometrial samples were obtained 7 days after ultrasonographic evidence that ovulation has occurred during the spontaneous cycle, then the patients were induced with CC from day 5 to day 9 during the subsequent cycle with 50 mg/day, and ovulation monitoring and endometrial biopsy were performed in the same manner. The samples were obtained using a Pipelle biopsy device without using local anesthesia, and kept in formaldehyde solution until the day of measurement. Then they were homogenized in phosphate buffered distilled water, and LIF levels were detected in the homogenized fluid by ELISA method. Endometrial LIF levels were 470 +/- 52 and 501 +/- 45 pg/1 gram wet tissue in spontaneous and CC-induced cycles respectively, revealing no significant difference. Ovulation induction with CC did not adversely affect endometrial LIF levels.
