Investigation of CD56, ADAM17 and FGF21 Expressions in the Placentas of Preeclampsia Cases.

In the present study, we investigated the expression of CD56, ADAM17 and FGF21 antibodies (Ab), which we think have an effect on the pathophysiology of preeclampsia (PE), in pregnant patients with healthy placentas and placentas with PE. The expression of these antibodies has been investigated in a limited amount of former research, but their role in PE has not yet been clarified. With this study, we aimed to contribute to the elucidation of the pathophysiology of PE and the detection of new target molecules for treatment.

Probable viremia and positive placental swabs for SARS-CoV-2 in a preterm pregnant woman with mild COVID-19.

This study aimed to report a case of mild novel coronavirus disease (COVID-19) in a pregnant woman with probable viremia, as reverse transcription-polymerase chain reaction (RT-PCR) testing of endometrial and placental swabs for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was positive. A 26-year-old multigravida at 35 weeks 2 days of gestation, who had extensive thigh and abdominal cellulitis, tested SARS-CoV-2 positive by RT-PCR performed on samples from the endometrium and maternal side of the placenta. However, other samples (amniotic fluid, fetal side of the placenta, umbilical cord, maternal vagina, and neonatal nasopharynx) tested negative for SARS-CoV-2.

Biological importance of podoplanin expression in chorionic villous stromal cells and its relationship to placental pathologies.

Podoplanin, a reliable marker of lymphatic endothelium, is a mucin-type transmembrane protein. Although the human placenta is devoid of a lymphatic system, chorionic villous stromal (CVS) cells express podoplanin. In this study, the pattern of podoplanin expression in normal and pathological placental tissues and the biological role of podoplanin were investigated.

Accuracy of the 24-h urine protein excretion value in patients with preeclampsia: correlation with instant and 24-h urine protein/creatinine and albumin/creatinine ratios.

The aim of this study was to determine the accuracy of the 24-h urine collection in preeclamptic pregnant women. This study included 65 singletons with preeclampsia and 53 singleton patients in a control-matched group. The ratio of inaccurate 24-h urine collection was measured by calculating expected urine creatinine excretion according to the proportion of pre-pregnancy weight and the lean body mass (LBM) of the patients.

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.

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.

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.

Primary brain T-cell lymphoma during pregnancy.

The incidence of non-Hodgkin's lymphoma (NHL) during pregnancy is about 0.8 cases per 100,000 women. We describe a case of a 33-year-old woman with primary brain T-cell NHL who was diagnosed at the 32nd week of gestation.

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.

Accuracy of intra-operative frozen section in the diagnosis of ovarian tumours.

Objectives: To compare frozen-section results with definitive histopathological results of ovarian tumours diagnosed intra operatively at the Zonguldak Maternity Hospital, Zonguldak, Turkey.

Methods: The definitive histopathological results of 278 patients who underwent surgery between January 2002 and December 2008 for ovarian masses and on whom frozen sectioning was performed were evaluated retrospectively. After exclusion of 12 patients for whom a definitive result could not be obtained from frozen sections, the results of 266 patients' frozen sections were compared with those from permanent sections.

Recurrent partial hydatidiform mole.

Hydatidiform moles are abnormal conceptions characterised by atypical hyperplastic trophoblasts and hydropic villi. Their incidence is approximately 1 in 1000 pregnancies. The recurrence risk of hydatidiform mole is approximately 1 in 60 in a subsequent pregnancy and 1 in 6.

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.

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.

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.

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.

Expression of heat shock protein 70 and endothelial nitric oxide synthase in placental tissue of preeclamptic and intrauterine growth-restricted pregnancies.

Ischemia, hypoxia, and elevated vascular resistance disturb placental functions by increasing oxidative stress. Heat shock protein 70 (HSP70) is an oxidative stress marker. Endothelial nitric oxide synthase (eNOS) is a nitric oxide enzyme with a key role in pathologic and physiologic angiogenesis and vasculogenesis.

Intrauterine growth restriction and placental angiogenesis.

Background: Vascular endothelial growth factor (VEGF), basic-fibroblast growth factor (b-FGF), and endothelial nitric oxide synthase (eNOS) are factors that take part in placental angiogenesis. They are highly expressed during embryonic and fetal development, especially in the first trimester. In this study, we aimed to investigate the role of placental angiogenesis in the development of intrauterine growth restriction (IUGR) by comparing the levels of expression of VEGF-A, b-FGF, and eNOS in normal-term pregnancy and IUGR placentas.

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.

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.

Design: Prospective quasi-randomized trial.

Setting: University infertility clinic.

Dyspeptic complaints after 20 weeks of gestation are not related to Helicobacter pylori seropositivity.

Background: This study was to test whether an association exists between Helicobacter pylori seropositivity and severity of dyspeptic symptoms after 20 weeks of gestation in pregnant women.

Material/methods: Pregnant women (n=103) with gestational ages between 20-41 weeks and healthy non-pregnant women (controls, n=79) were prospectively enrolled in the study. Anti-H.

Investigation of human colostrum Helicobacter pylori IgA content in lactating women.

Objective: The objective was to investigate the colostral H. pylori-specific IgA content in a sample of the female population in Turkey where a high endemicity for H. pylori has always been reported.

Statins have additive effects to vertebral bone mineral density in combination with risedronate in hypercholesterolemic postmenopausal women.

Background: Recent data suggest that statins used in the treatment of hypercholesterolaemia decrease fracture risk. In this study, we aimed to investigate prospectively whether statins have an additive effect to bisphosphonates (risedronate) according to the primary hypothesis that the addition of atorvastatin to risedronate would produce an increase, from baseline, in lumbar vertebrae and total hip BMD that was greater than that observed with risedronate alone.

Methods: A total of 120 hypercholesterolaemic postmenopausal women with osteoporosis or osteopenia were randomized to receive risedronate (5 mg/day) or risedronate (5 mg/day) plus atorvastatin (20 mg/day).

Transabdominal pulse inversion harmonic imaging improves assessment of ovarian morphology in virgin patients with PCOS: comparison with conventional B-mode sonography.

Objective: In virgin policystic ovary syndrome (PCOS) patients transabdominal sonography is the preferential method of the pelvic examination. The purpose of this study was to determine ovarian morphology by the transabdominal route by pulse inversion harmonic imaging (PIHI) in virgin PCOS patients and to compare the diagnostic image quality with conventional B-mode ultrasonography (CBU).

Methods: Fifty-two ovaries in 26 virgin patients were evaluated by the transabdominal approach.
