Oxidative stress and apoptosis in preeclampsia.

We aimed to determine the oxidative stress and antioxidant status in preeclamptic placenta. Also, we investigated the apoptotic index of villous trophoblast and proliferation index of cytotrophoblasts. The study included 32 pregnant with preeclampsia and 31 normotensive healthy pregnant women. Malondialdehyde (MDA) and total antioxidant status (TAS) levels were measured in the placenta. For detection of apoptosis and proliferation in trophoblast, apoptosis protease activating factor 1 (APAF-1) and Ki-67 were used. Placental MDA levels in preeclamptic women were significantly higher than normal pregnancies (p=0.002). There was no significant difference between the groups in the TAS levels of placenta (p=0.773). Also, the apoptotic index in villous trophoblasts increased (p<0.001), but proliferation index did not change in preeclampsia (p=0.850). Increased oxidative stress and apoptosis in pathological placenta are not balanced by antioxidant systems and proliferation mechanisms.

Unilateral ovarian agenesis and clear cell type epithelioid leiomyoma of uterus mimicking ovarian malignancy.

A case of unilateral absent ovary together with clear cell type epithelioid leiomyoma of uterus mimicking ovarian malignancy discovered during laparotomy is presented. Unilateral absence of an ovary is an extremely rare finding. Although the exact pathophysiological mechanism is not known, it could result from a defect in embryological development or asymptomatic torsion of ovary. Clear cell type epithelioid leiomyoma of uterus is also a rare variant, composed of round or polygonal 'clear' cells rather than typical spindle-shaped cells and ultra structurally differs from non-uterine counterparts.

Sexual dysfunction in infertile couples: evaluation and treatment of infertility.

OBJECTIVE: To evaluate the diagnostic and the predictive value of Arizona Sexual Experience Scale among primary infertile couples regarding sexual dysfunction. METHODS: The cross-sectional and prospective pre, post study comprising primary infertile patients was carried out at Bulent Ecevit University Hospital, Zonguldak, Turkey. Fifty consecutive primary infertile couples not treated previously were investigated between 2003 and 2007 for the presence of sexual dysfunction by a psychiatrist. Arizona Sexual Experience Scale scoring was self-administered to determine sexual dysfunction among couples before treatment and also 3 months after the initiation of the treatment. RESULTS: Pretreatment mean values of the index parametres in both women and men were significantly increased after treatment. Statistically significant positive correlation was observed between pre- and post-treatment total scores in both women (r = 0.83; p < .001) and men (r = 0.92; p < .001). Receiver operating characteristic curve analyses revealed optimum cut-offs of pre- and post-treatment scores in women were were > 14 (Sensitivity: 57%; Specificity: 90%) and > 13 (Sensitivity: 83%; Specificity: 93%), respectively. Pre- and post-treatment scores in men were > 10 (Sensitivity: 65%; Specificity: 61%), > 11 (Sensitivity: 83%; Specificity: 62%), respectively. Binary logistic regression analyses revealed women's pre-treatment and post-treatment scores as a significant factor for prediction of sexual dysfunction independent of sociodemographic factors (p = 0.001 and p = 0.001, respectively). CONCLUSION: Evaluation and treatment of infertility is an important risk factor for sexual dyfunction. Pre- and posttreatment Arizona Sexual Experience Scale score could be used as a screening test for sexual dysfunction and might be used to decide pre/post-treatment consultation of couples with a specialist.

Endometrioma ≤3 cm in diameter per se does not affect ovarian reserve in intracytoplasmic sperm injection cycles.

BACKGROUND: Our aim was to determine the effect of single endometriomas ≤3 cm in diameter per se on ovarian reserve in intracytoplasmic sperm injection (ICSI) cycles. METHODS: We enrolled 19 consecutive infertile patients (29 cycles) who had unilateral single endometriomas ≤3 cm in diameter and who underwent ICSI. RESULTS: The mean age of the patients was 33.3 ± 4.9 years. The mean diameter of endometriomas was 21.8 ± 4.9 mm. Left- and right-sided endometriomas were 34.5 and 65.5%, respectively. The number of oocytes retrieved from ovaries with endometriomas and contralateral normal ovaries was comparable (5.9 ± 4.3 vs. 5.4 ± 3.8). CONCLUSION: Endometriomas ≤3 cm in diameter per se did not have a deleterious effect on ovarian reserve in ICSI cycles.

Placental chorangiosis: the association with oxidative stress and angiogenesis.

BACKGROUND/AIMS: Chorangiosis is considered to be strongly associated with fetal, maternal, and placental disorders, and has been found to be correlated with increased fetal morbidity and mortality. In this study, it is aimed to investigate the association of angiogenesis and oxidative stress with the pathogenesis of chorangiosis. METHODS: Expressions of heat shock protein 70 (HSP70), vascular endothelial growth factor-A (VEGF-A) and basic fibroblast growth factor (b-FGF), which are investigated with avidin-biotin-peroxidase method in formalin-fixed, paraffin-embedded sections from placental tissues diagnosed as no chorangiosis (n = 18) and chorangiosis (n = 18), have been evaluated in a semiquantitative manner. RESULTS: There were significant differences between chorangiosis and no chorangiosis cases with respect to birth weight, birth length, and Apgar scores (p < 0.001). Statistically significant (p < 0.001), diffuse and strong expressions with HSP70, VEGF-A and b-FGF were observed in the villous tissue of placental chorangiosis cases when compared with no chorangiosis cases. CONCLUSION: The majority of the chorangiosis cases had an accompanying poor perinatal outcome, and also those with accompanying angiogenesis and increased oxidative stress demonstrated diffuse and strong expressions of HSP70, VEGF-A and b-FGF. The interaction of maternal, placental, and fetal factors with increased oxidative stress and angiogenesis may possibly contribute to this arising pathologic change.

Comparative study of oxidative stress in maternal blood with that of cord blood and maternal milk.

OBJECTIVE: Oxidative stress has been implicated in pregnancy-induced hypertension and preeclampsia. There is still some debate over whether this is confined to the placenta or occurs in the maternal circulation. This study was designed to investigate this question by comparing parameters of oxidative stress in samples of maternal blood and cord blood taken from normotensive and hypertensive pregnant women. A further aim was to compare these parameters in maternal milk from the two populations. STUDY DESIGN: Forty-six hypertensive (31 preeclamptic and 15 chronic hypertensive) and 60 normotensive pregnant women were recruited. Antecubital blood was collected from each woman before and after delivery, cord blood just after delivery, and maternal milk for the first 3 days postpartum. Total antioxidant capacity, total peroxides and sulphydryl concentration were measured and total antioxidant capacity calculated for each specimen. RESULTS: For all specimens (maternal blood plasma, cord blood plasma, maternal milk) total antioxidant capacity and sulphydryl concentration were significantly lower in the hypertensive women than in the normotensive, while total peroxide and oxidative stress index were significantly higher. CONCLUSION: These results support the association between hypertension in pregnancy and oxidative stress and the view that this occurs throughout the maternal circulation. They show further that oxidative stress may be transmitted from mother to newborn in maternal milk. Supplementation with antioxidants could, in view of our findings, possibly provide protection to the mother and fetus and also, through transmission in maternal milk, to the newborn.

Primary pulmonary sarcoma metastasising to the skin during pregnancy.

Lung cancer during pregnancy is a rare situation which is being increasingly reported during the past two decades due to a rising trend of cigarette smoking among young women and the tendency to delay pregnancy to a later age in life. We describe the case of a 32-year-old woman with primary pulmonary sarcoma, diagnosed at 31st week of pregnancy. X-ray chest and thoracic magnetic resonance imaging revealed a 9 x 6 cm mass in the left mediastinum, with tracheal shift, and pleural effusion. Biopsy performed during broncoscopy, was reported as mesenchymal tumour. She delivered a baby by Caesarean section at the 32nd week of gestation due to the development of superior vena cava syndrome. A skin biopsy taken 3 weeks later from the nodular lesion at the periumblical region was reported as a tumour metastasis. She received radiotherapy for 10 days, but died in the intensive care unit. Malignancies, even those as uncommon as a pulmonary sarcoma, should be considered in the differential diagnosis of pleural effusion during pregnancy.

Comparison of the histopathological diagnoses of preoperative dilatation and curettage and hysterectomy specimens.

AIM: A biopsy is often taken as part of the preoperative workup, regardless of the indication for hysterectomy. Some authors believe that dilatation and curettage is a poor diagnostic procedure for intrauterine pathologies, but dilatation and curettage has been the method of choice for obtaining an endometrial sample. The aim of this study was to investigate the concordance between endometrial histopathological diagnoses from preoperative dilatation and curettage and hysterectomy specimens. The differences between premenopausal and postmenopausal women were also investigated. METHODS: Histopathological results for dilatation and curettage specimens from 645 women (401 premenopausal and 244 postmenopausal) who underwent a hysterectomy between 2003 and 2009 were analyzed retrospectively. RESULTS: High sensitivity (87.8%), specificity (100%), positive (100%) and negative (98.7%) predictive values, and accuracy (98.8%) were observed for all malignant endometrial pathologies obtained at dilatation and curettage. In postmenopausal women, eight malignancies were missed when the preoperative diagnosis from the dilatation and curettage sample indicated inadequate tissue or premalignant lesions. For premenopausal women, we found only two missed malignancies. The accuracy was 99.5% and 96.8% for malignant pathologies diagnosed from curettage material for pre- and postmenopausal women, respectively. CONCLUSIONS: Dilatation and curettage remains the 'gold standard' for diagnosing endometrial pathologies, especially malignancies.

Idiopathic ileoileal invagination two days after cesarean section.

Postoperative enteroenteric invagination is rare. The only previously reported case post-cesarean was secondary to colonic adenocarcinoma. A 27-year-old woman with preeclampsia delivered a baby by cesarean section. On the second postoperative day, she had abdominal pain, nausea, vomiting, constipation, and distention. An abdominal x-ray showed air-fluid levels, while free fluid (ascites) was detected by ultrasonography. A computed tomography scan did not show the typical invagination picture. Her condition did not improve after 72 h of conservative treatment, and diagnostic laparotomy was performed. A 10 × 3-cm ileoileal invagination 80 cm proximal to the ileocecal valve was found and manually reduced. The patient was discharged on the fifth postoperative day, and her six-month follow-up was normal.

Turkish obstetricians' personal preference for mode of delivery and attitude toward cesarean delivery on maternal request.

OBJECTIVE(S): (1) To investigate the cesarean rate among actively practicing obstetricians in Turkey and reasons why they choose this mode of delivery for themselves/partners. (2) To investigate the attitudes, practices, and beliefs with respect to cesarean delivery on maternal request (CDMR) among actively practicing obstetricians in Turkey. STUDY DESIGN: This is a descriptive study performed at 7th Congress Of Turkish Society Of Gynecology and Obstetrics. A self-administered questionnaire was used for data collection. During the congress, from the obstetricians attending the congress, 500 were randomly selected; due to the room numbers, the questionnaires (total, 500) and the consent forms were distributed every fourth room. The sampled obstetricians were instructed to return the completed questionnaires and signed consent forms to the congress information desk located throughout the congress. In total, 387 (77.4%) obstetricians responded. RESULTS: Of the respondents (if female) or their partners (if male), 239 (61.8%) respondents had undergone at least one previous cesarean section (CS), and, of these, 212 (88.7%) were primary elective cesarean deliveries. The most common reason influencing the decision of obstetricians in choosing CS for themselves/partners was reduced anorectal trauma (63.6%). In addition, 158 (40.8%) of the respondents believe that every woman has the right to request a cesarean as a mode of delivery. About half of the respondents (53.2%) said that they would perform a patient-requested CS. The most common reason why obstetricians perform CS due to maternal request was 'anxiety of patient and her partner and due to their insistence'. CONCLUSIONS: Two-thirds of Turkish obstetricians prefer CS as mode of delivery for themselves/partners. Also half of the obstetricians in our study believe that a woman has the right to request and obtain CDMR, and half of them would agree to perform one.

Ovarian cancer during pregnancy.

The frequency of cancer during pregnancy is approximately 1 per 1000 live births. This rate may increase as more women postpone childbirth until later in life, when cancer becomes more frequent. Pregnancy affects management of the cancer, and the cancer affects the management of pregnancy. The most common malignancies, in order of frequency, are breast cancer, leukaemia and lymphomas as a group, melanoma, gynaecologic cancers, and bone tumours. Ovarian tumours are found in about 1 in 1000 pregnancies and 3-6% of these are malignant. Thus, ovarian cancer occurs in approximately 1 in 12,500-25,000 pregnancies. Here, we report a case of ovarian mucinous carcinoma that was diagnosed at 22 weeks of gestation. After conservative surgery, she was given three cycles of carboplatin chemotherapy. She delivered at 33 weeks of gestation and after undergoing surgery she was given six cycles of paclitaxel and carboplatin chemotherapy. The patient is now being followed by the oncology department with no evidence of disease.

Endothelial nitric oxide synthase expression in gestational trophoblastic diseases.

OBJECTIVE: Nitric oxide is thought to play a role in the regulation of trophoblast activity. The aim of this study was to compare endothelial nitric oxide synthase expression in tissue samples taken from gestational trophoblastic diseases and placentas of normal pregnancies. METHODS: The expression of endothelial nitric oxide synthase was tested in formalin-fixed, paraffin-embedded tissues from specimens including 8 first trimester placentas, 3 partial hydatidiform moles, 20 complete hydatidiform moles, 2 invasive moles, and 5 choriocarcinomas. The expression of antibody was scored by a semiquantitative scale to define staining intensity. RESULTS: The first trimester placentas showed moderate expression in the villous. Gestational trophoblastic diseases displayed strong to very strong endothelial nitric oxide synthase expression in the syncytiotrophoblast, villous, and proliferating mononuclear trophoblasts. CONCLUSIONS: Endothelial nitric oxide synthase expression seems to have a strong correlation with proliferation of trophoblastic cells, in gestational trophoblastic diseases and in normal pregnancy.

Herlyn-Werner-Wunderlich syndrome (uterus didelphys, blind hemivagina and ipsilateral renal agenesis) - a case report.

Uterovaginal duplication with obstructed hemivagina and ipsilateral renal agenesis is referred to as the Herlyn-Werner-Wunderlich (HWW) syndrome. A 17 year old woman presented with right pelvic pain and dysmenorrhea, present since menarche at 13 and worsening over the past year. Ultrasound examination revealed a right pelvic mass (5×5 cm), double endometrial echoes, and hematocolpos. A right pelvic mass, agenesis of the right kidney, double uterus, and blind hemivagina with hematocolpos were detected by magnetic resonance imaging and intravenous pyelography. A right tubo-ovarian abscess with dense adhesions and a double uterus were observed on diagnostic laparoscopy. Adhesiolysis was carried out and purulent material irrigated. After a course of antibiotics, a vaginal septum resection was performed and the pyocolpos drained. She remained symptom free after four months of follow-up. Prompt and accurate diagnosis and treatment of this syndrome can significantly improve the lives of sufferers and prevent future complications.

Comparison of serum androgens and endometrial thickness in obese and non-obese postmenopausal women.

OBJECTIVE: In this study, we investigated whether serum androgen levels and endometrial thickness differed in obese and non-obese women. MATERIAL AND METHODS: Thirtytwo non-obese (BMI <30) and 48 obese (BMI ≥ 30) women were enrolled. Blood samples were analyzed for testosterone, free testosterone, androstenedione, DHEAS, and SHBG, and transvaginal ultrasonography was performed. RESULTS: Obese women had significantly higher free testosterone and endometrial thickness and significantly lower SHBG. Eight of 17 women with endometrial thickness >5 mm had significant pathology. CONCLUSION: These results suggest that obesity may be a risk factor for endometrial carcinoma and other pathologies in post-menopausal women through an action on androgen concentrations.

Prenatally diagnosed partial trisomy 3q case with an omphalocele and less severe phenotype.

Trisomy 3q is a very rarely reported chromosomal disorder. Duplication of part of the long arm of human chromosome 3 causes a distinct and severe syndrome that leads to multiple congenital abnormalities. A 27 year-old pregnant woman was admitted to our clinic at 17 weeks of gestation. Prenatal sonography identified a fetus with an omphalocele that contained the liver and bowel, mild ventriculomegaly and polyhydramnios. Amniocentesis revealed the karyotype of 46, XY, der (3) (3qter→3q21: : 3pter→3qter). The pregnancy was subsequently terminated. Postnatally, the proband showed midfacial hypoplasia, micrognathia, hypoplastic 12th ribs, omphalocele and prominent heels. We reported this partial trisomy 3q case because he had less marked malformations compared to other reported cases and also different features such as an omphalocele and hypoplastic 12th rib which have not been described previously in an isolated Trisomy 3q case with this karyotype.
