Increased C4d and Bb immunoreactivity and decreased MBL immunoreactivity characterise first-time pathologic first-trimester miscarriage: a case-control study.

The role of the complement system in first-time pathologic first-trimester miscarriage was investigated. In this case-control study, tissue samples of 126 women with pathologic miscarriage and termination of normal pregnancies were assessed. The pathologic pregnancy group consisted of 40 women with missed miscarriage, 13 women with incomplete miscarriage and 10 women with a blighted ovum. The control group consisted of 63 normal-appearing pregnancies. Immunoreactivity for C4d, Bb and MBL was evaluated in the deciduas and villous trophoblasts separately using a semi-quantitative histological scoring system (H-score). C4d and Bb H-scores were higher and MBL H-score was reduced in the deciduas and villous tissues from pathologic miscarriage compared to termination of pregnancies (p = .003 and p = .001; p = .011 and p < .001; p < .001 and p < .001, respectively). C4d and Bb activities were increased and MBL activity was decreased in human first-time pathologic first-trimester miscarriage. We suggest that three complement pathways may play a role in human first-time pathologic first-trimester miscarriage. Impact statement Previous studies focussed on complement proteins related to a single complement pathway in cases often associated with antiphospholipid syndrome (APS) or recurrent miscarriage. In APS-related cases, the classical pathway is activated. In antibody-dependent and in antibody-independent mouse models of foetal loss, classical and alternative pathways are activated, respectively. Lectin pathway deficiency has been reported in some recurrent miscarriage. The complement pathway or pathways, which have a role in human pathologic miscarriage was the starting point of this study. There has been no study done till now reporting the role of the three complement pathways in human pathologic miscarriage. In this study, we found increased classical and alternative complement pathway activities and decreased lectin pathway activity in tissues from first-time pathologic human miscarriage.

Prenatal diagnosis of a 22q11 deletion in a second-trimester fetus with conotruncal anomaly, absent thymus and meningomyelocele: Kousseff syndrome.

A 30-year-old nulliparous woman was seen for a detailed ultrasound scan at 20 weeks of gestation. The scan revealed a male fetus with truncus arteriosus, membranous ventricular septal defect, absent thymus and sacral meningomyelocele. A 46,XY karyotype with a 22q11 deletion was detected. The parents chose to terminate the pregnancy. The pathological autopsy showed normal facial structures, minimal ventricular dilatation in the brain and a sacral meningomyelocele. Overlapping toes and a left claw-hand were also noted. An aplastic thymus with absent parathyroid glands was detected. The cardiac examination was consistent with the ultrasound diagnosis. The parental karyotypes were both normal. Kousseff syndrome is caused by a chromosome 22q11 deletion. It includes sacral meningomyelocele and conotruncal heart defects, unlike DiGeorge syndrome. Obstetricians should consider this a not so rare entity when they detect conotruncal abnormalities and a meningomyelocele as part of a 22q11.2 deletion syndrome.

The effects of resistance training on cardiovascular disease risk factors in postmenopausal women: a randomized-controlled trial.

Our aim was to determine the effects of resistance training on cardiovascular risk factors in postmenopausal women. Forty-five women were included in the study. Resistance exercises were done with an intensity of 60% of 1-Repetition Maximum, for 12 weeks. Heart rate, blood pressure, estimated peak VO(2), lipid profiles, and homocysteine levels were evaluated. There were significant time and group interactions for body mass index (p = .02), heart rate (p = .04), systolic blood pressure (p = .03), estimated mean peak VO(2) (p = .00), and total cholesterol (p = .00), but there were no interactions with other evaluated parameters. Resistance training has beneficial effects on particular cardiovascular risk factors in postmenopausal women.

Analysis of perinatal outcome by combination of first trimester maternal plasma homocysteine with uterine artery Doppler velocimetry.

OBJECTIVE: To analyse the pregnancy outcome by combining plasma homocysteine with uterine artery Doppler velocimetry at 11 to 14 weeks of gestation. METHOD: A prospective cohort study with 103 healthy pregnant women. Uterine artery Doppler velocimetry was performed at between 11 and 14 weeks of gestation. Abnormal blood flow was defined as average pulsatility index >1.5 and presence of unilateral or bilateral diastolic notch. Doppler scores were calculated by a modified scoring method of uterine artery flow velocity waveforms. Serum for measurement of homocysteine, vitamin B(12) and folate levels were collected when the ultrasonographic measurement was performed. RESULTS: Pre-eclampsia developed in five, gestational hypertension in three, intrauterine growth restriction in two and preterm birth in eight patients. There was a significant difference between mean plasma homocysteine levels at different Doppler scores (p<0.001) and a weak positive correlation between Doppler scores and occurrence of pregnancy complications (r(s) = 0.232, p<0.05). Mean homocysteine level increased with increasing Doppler scores. Any uterine artery abnormality had a sensitivity of 88.9% in predicting obstetric complications. Addition of hyperhomocytenemia to Doppler scores did not change the sensitivity. CONCLUSION: Maternal serum homocysteine level is increased in 11 to 14 weeks of gestation that is complicated with pre-eclampsia, gestational hypertension, intrauterine growth restriction and preterm birth. Addition of homocysteine determination to uterine artery Doppler in the first trimester does not add any advantage in predicting adverse perinatal outcome.

Prenatal detection of Peters plus-like syndrome.

Peters plus syndrome is a rare congenital disorder that includes ocular anterior segment defects of the classic Peter's anomaly, and is mostly associated with craniofacial and skeletal defects. A 21-week fetus was referred for further evaluation due to a suspicion of fetal hydrocephalus. An ultrasound examination revealed hyperechogenic lenses, microphthalmia, hypotelorism, retrognathia, mild ventriculomegaly, absence of the cavum septum pellucidum, and short stature. Amniocentesis and further microarray analysis revealed normal chromosomal copy numbers including the gene B3GALTL. In utero mort fetalis occurred at the 23rd gestational week. Ultrasound and fetal autopsy findings were suggestive of Peters plus syndrome, but the absence of the B3GALTL gene mutation made the diagnosis Peters plus-like syndrome. Obstetricians should consider Peters plus-like syndrome with prenatal detection of ocular anomalies along with craniofacial and skeletal anomalies with the absence of B3GALTL gene mutation.

Fetal Nasal Bone Length as a Novel Marker for Prediction of Adverse Perinatal Outcomes in the First-Trimester of Pregnancy.

BACKGROUND: Adverse outcomes of pregnancy are a challenging health-care problem. Prediction of adverse pregnancy outcomes is important to prevent the morbidities of the foetus and the mother. AIMS: To study the clinical interest of fetal nasal bone length in predicting adverse pregnancy outcomes in the first trimester of pregnancy. STUDY DESIGN: A population-based retrospective cohort study. METHODS: Data from 868 women with first-trimester fetal nasal bone length and birth records available were enrolled. Fetal nasal bone length percentiles were determined and evaluated for their ability to predict adverse pregnancy outcomes such as preterm birth, preterm labour, preterm premature rupture of membranes, early preterm birth, gestational diabetes mellitus, gestational hypertension-preeclampsia, small-for-gestational age foetuses, macrosomia, oligohydramnios, polyhydramnios and fetal distress. RESULTS: Fetal nasal bone length >95th percentile was significantly associated with preterm labor and preterm premature rupture of membranes (p=0.02, accuracy 0.91 and p=0.001, accuracy 0.94, respectively), whereas nasal bone length >99th percentile was significantly associated with preterm labor and oligohydramnios (p=0.006, accuracy 0.95 and p=0.014, accuracy 0.97). CONCLUSION: Fetal nasal bone length at high percentiles in the first trimester of pregnancy may aid in the prediction of adverse outcomes such as preterm labour, preterm premature rupture of membranes and oligohydramnios.

Fetal gender affects maternal serum total and placental alkaline phosphatase levels during pregnancy.

OBJECTIVE: To analyze whether fetal gender affects total alkaline phosphatase (ALP) and placental ALP levels in normal pregnancy, and to determine the gestational age at which the difference occurs. METHODS: In this longitudinal study, serum total and placental ALP measurements were carried out in 30 normal pregnant women during different ranges of gestational weeks. Infant sex was recorded at the delivery for all women included in the study. Total and placental ALP levels were compared between pregnant women bearing female and male fetuses. RESULTS: At all gestational weeks studied, both total and placental ALP levels were higher in pregnant women carrying female fetuses than in male bearing pregnant women. Particularly, both total (260.9+/-110.2 versus 239.9+/-102.3; p=0.03) and placental (73.1+/-22.4 versus 61+/-18.2; p=0.04) ALP levels were significantly higher in the female group than in the male between 24 and 28 weeks, and the significant difference persisted between 32 and 36 weeks (p=0.02). CONCLUSIONS: Fetal gender seems to affect total and placental ALP levels in healthy pregnant women, particularly during the second and third trimester of pregnancy. Higher ALP levels in pregnant women with female fetuses than in those with male fetuses may suggest that knowledge of the fetal gender may be in particular importance for the studies using ALP as a marker for the prediction of variety of diseases and complications seen during pregnancy.

Primary dysmenorrhea and uterine blood flow: a color Doppler study.

OBJECTIVE: To examine pulsatility index (PI) and resistance index (RI) values in the uterine and arcuate arteries of patients with primary dysmenorrhea (PD) by color Doppler ultrasonography. STUDY DESIGN: A total of 49 female university students were recruited for this prospective, observational study. The study group consisted of 25 nulliparous women with PD and a control group of 24 healthy, nulliparous women without dysmenorrhea. The women were examined using transabdominal color Doppler ultrasonography during the midluteal phase (days 18-22) and on the first day of the menstrual cycle. The mean PI and RI values for the right and left uterine arteries and arcuate artery were determined. Student's t test was used to compare the results between and within groups. RESULTS: The mean PI and RI values for the uterine and arcuate arteries in patients with PD were significantly higher on the first day of the menstrual cycle than in the midluteal phase (p < 0.001). Women with PD had significantly higher mean PI and RI values in all 3 arteries on the first day of the menstrual cycle than did the controls (p < 0.05). The Doppler index values of all 3 arteries during the midluteal phase were not significantly different between the groups. CONCLUSION: There is increased impedance to blood flow within the uterus of women with PD on the first day of the menstrual cycle. This may be a sign of constriction of the uterine vessels and the cause of pain.

Expression of IGR-IR and VEGF and trophoblastic proliferative activity in placentas from pregnancies complicated by IUGR.

Intrauterine growth retardation (IUGR) is recognized as an important cause of low birth weight and elective preterm delivery. IUGR is associated with multiple causative factors, including placental dysfunction. The aim of this prospective study was to investigate the role of trophoblastic proliferative activity and type I insuline-like growth factor receptor (IGF-IR) and vascular endothelial growth factor (VEGF) expressions in the pathogenesis of IUGR. Immunohistochemistry using VEGF, IGF-IR, and Ki-67 antibodies was performed on formalin-fixed placental tissues of third-trimester pregnancies complicated by IUGR (n = 19) and pregnancies with appropriately grown fetuses (n = 27). In addition, histopathological examination of the placentas was performed, and histological findings were categorized into three groups: utero-placental vascular pathologies (UPVP), coagulation-related pathologies, and chronic inflammation. Statistical analysis revealed that villous trophoblastic IGF-IR immunostaining was significantly weaker in placentas with IUGR (p < 0.001), whereas trophoblastic Ki-67 proliferative index and VEGF immunoscoring did not show any significant difference. Histologically, UPVP and chronic inflammation were significant findings in placentas with IUGR (p = 0.04 and p = 0.04, respectively). In addition, placentas were significantly smaller in the IUGR group (p < 0.001). We conclude that villous trophoblastic IGF-IR expression may play a significant role in the pathogenesis of IUGR, and histopathological examination of placentas in pregnancies complicated by IUGR may yield significant findings. In contrast, based on our findings, trophoblastic proliferation and VEGF expression are unlikely to be significant parameters in the pathogenesis of IUGR.

A randomized controlled trial of coil removal prior to treatment of pelvic inflammatory disease.

OBJECTIVE: To evaluate the effects of removing coils on the treatment of mild and moderate pelvic inflammatory disease (PID). METHODS: Of 126 women who had mild to moderate PID during coil usage, 60 were treated following coil removal and 66 without. Clinical symptoms, findings of gynecologic examination, erythrocyte sedimentation rates (mm/h), leukocyte counts (mm(-3)) were recorded before and after treatment and recovery rates of symptoms and findings were compared with Chi-square and Fisher's absolute Chi-square tests. Student's t-test was used for the comparison of mean sedimentation rates and leukocyte counts. RESULTS: Recovery rates of pelvic pain, purulent vaginal discharge, dysuria/frequency and dyspareunia and clinical improvements in abdominal and cervical tenderness were significantly higher (P<0.05) in the coil removed group. CONCLUSIONS: Removing the coil before medical therapy, increases the rates of clinical improvement in mild to moderate PID.

Velamentous and Furcate Cord Insertion with Placenta Accreta in an IVF Pregnancy with Unicornuate Uterus.

Velamentous and furcate cord insertion with concomitant placenta accreta is a very rare and life-threatening event of pregnancy for both the mother and the fetus. Obstetricians should be cautious about umbilical cord insertion and placental adherence abnormalities in pregnancies conceived by assisted reproductive technologies (ART) particularly in women with Müllerian anomalies.

Ferritin and bile acid levels during the intrauterine pre-treatment of gastroschisis by serial amnioexchange.

We present a case of gastroschisis managed with serial amnioex-changes. Marked decreases were detected in both ferritin and bile acid levels following the procedure. The bowels were not severely affected, as expected. After delivery, single primary closure of the defect was performed. Early enteral feeding and shorter hospital stay were the main outcome measures. Intrauterine pre-treatment of gastroschisis by serial amnioexchange may provide benefits by decreasing the levels of inflammatory products in the amniotic fluid in order to lower the possible risk of bowel damage, and this may help to achieve better surgical and postnatal outcomes.

Neonatal outcome of fetuses receiving intrauterine transfusion for severe hydrops complicated by Rhesus hemolytic disease.

OBJECTIVE: To evaluate neonatal outcomes among a homogeneous group of fetuses with severe hydrops treated with intrauterine transfusion (IUT). METHODS: In a prospective study at Dokuz Eylul University School of Medicine, Izmir, Turkey, outcomes were compared for 35 IUTs carried out between 2005 and 2010 in 19 pregnancies that were complicated by Rhesus D hemolytic disease with severely hydropic fetuses. RESULTS: There was no correlation between the number of IUTs and the duration of phototherapy or number of exchange transfusions. After delivery, 36% (7/19) of neonates tested positive in a direct Coombs test and their requirement for exchange transfusion was higher than that of neonates who tested negative. The neonatal survival rate was 73.7%. Admission to the neonatal intensive care unit was 78%, and the median duration of neonatal unit stay was 4 days (range, 1-77 days). Only 1 newborn had hearing impairment. CONCLUSION: IUT is a unique, gold standard treatment for severely hydropic fetuses. When treated optimally with IUT, fetuses with severe hydrops showed no increased risk of neurodevelopmental abnormalities. Factors affecting the survival of hydropic fetuses after IUT, and whether the number of IUTs performed affects the number of exchange transfusions required remain unclear.

Clinical results of the liquid-based cervical cytology tool, Liqui-PREP, in comparison with conventional smears for detection of squamous cell abnormalities.

OBJECTIVE: To compare the adequacy and efficacy of the liquid-based cytology tool Liqui-PREP (LP) with the conventional Papanicolaou smear (CS) test, for the screening of squamous cell abnormalities. METHODS: Data for 2,000 subjects screened with CS and 4,000 different subjects screened with the LP test were compared. RESULTS: LP showed significant decrease in the rate of unsatisfactory smears (P<0.01) and the detection rate for atypical squamous cells was significantly higher (P<0.01). The rate of low-grade squamous intraepithelial lesion was also higher, but this did not reach statistical significance. The number of high-grade squamous intraepithelial lesions detected was increased with LP, and the histological correlation of LSIL lesions showed a higher positive-predictive value. The coexistence of abnormal colposcopic findings with abnormal smear results was higher for LP (P<0.004). Furthermore, high-risk HPV-DNA detection was found to be increased in atypical LP smears than in normal LP smears. CONCLUSIONS: The liquid-based cytology tool LP detected more squamous cell lesions than CS. Also it reduced the number of unsatisfactory results due to enhanced cell visualization, and improved screening for HPV-DNA.

Domestic violence on pregnant women in Turkey.

OBJECTIVE: Domestic violence is accepted worldwide as an important health problem. Besides diagnosis and treatment process, there are difficulties when considering of medico-legal evaluation of pregnant women subjected to domestic violence. As a signatory of the ''Convention on the Elimination of All Forms of Discrimination Against Women (CEDAW)'' Turkey has certain commitments regarding domestic violence and made regulations on national law. The purpose of the present study is to demonstrate the prevalence of domestic violence during pregnancy among the women who applied to obstetrics clinics and evaluating of the participants' knowledge level about the legal legislation concerning domestic violence. FINDINGS: Pregnant women attending for antenatal care to department of Gynecology and Obstetrics were interviewed using an anonymous and confidential questionnaire. The questionnaire used was a version of Abuse Assessment Screen with guidance of references. 28 (13.4%) women stated that they had been subjected to violence before pregnancy. Only 10 (4.67%) women had stated experience of violence during pregnancy. 148 (69.2%) of them had stated that they had no knowledge about any legislation concerning domestic violence in our country. CONCLUSION: We believe that society awareness should be increased and the health workers should be informed about their ethical and legal responsibilities concerning domestic violence during pregnancy. The knowledge and sensitivity of health care personnel in Prenatal Clinics and Family Planning Services should be increased and examination protocols should be provided about domestic violence against pregnant women.

Effect of fetal gender on maternal serum human chorionic gonadotropin levels throughout pregnancy.

OBJECTIVES: Maternal serum human chorionic gonadotropin (MshCG) levels are higher in pregnant women with female fetuses than in pregnant women with male fetuses in the third trimester of pregnancy. Our aim was to examine the effect of fetal sex on MshCG levels throughout the pregnancy. MATERIALS AND METHODS: Twenty-nine uncomplicated pregnancies (14 had male fetus and 15 had female fetus) were included in the study. MshCG levels were measured four times between 8-12, 14-18, 24-28 and 32-36 weeks of pregnancy. RESULTS: MshCG levels were significantly higher in both sexes between 8-12 weeks than the other three measurement periods. At 8-12 and 14-18 weeks measurements, there were no sex related differences in the MshCG levels. At 24-28 (P<0.004) and 32-36 (P<0.001) weeks MshCG levels were significantly higher in pregnancies bearing female fetuses than those bearing male fetuses. CONCLUSIONS: Fetal gender has a significant effect on MshCG levels in the third trimester of pregnancy. Accordingly, no correlation seems to exist in the first and second trimesters.
