Abstract

Background: Preeclampsia is a disorder unique to pregnancy and has long been recognized as an important contributor of maternal and fetal morbidity and mortality. It is suggested that cytokines such as Tumor Necrosis Factor-alpha (TNF-α) have an important role in the pathogenesis of preeclampsia and may cause generalized endothelial dysfunction.
Objective: The aim of this study was comparison of maternal serum TNF-α in severe and mild preeclampsia versus normal pregnancy.
Materials and Methods: This study was performed on 37 women with preeclampsia (17 mild and 20 severe preeclampsia) and 41 normotensive pregnant women with similar gestational age at third trimester of pregnancy. All the preeclamptic cases had blood pressure ≥ 140/90 mmHg and proteinuria ≥ 300 mg in a 24-h urine sample. Maternal serum TNF-α concentration was compared in all of them.
Results: The level of TNF-α concentration was not statistically different between the studied groups. No significant correlation was found between preeclampsia and control group as they were compared in the view of maternal serum TNF-α concentration.
Conclusion: These findings suggest that serum TNF-α is not significantly associated with preeclampsia.

Abstract

Background: The physiological changes in thyroid gland during pregnancy have been suggested as one of the pathophysiologic causes of preeclampsia.
Objective: The aim of this study was comparison of serum levels of Tri?iodothyronine (T3), Thyroxine (T4), and Thyroid?Stimulating Hormone (TSH) in preeclampsia and normal pregnancy.
Materials and Methods: In this case?control study, 40 normal pregnant women and 40 cases of preeclampsia in third trimester of pregnancy were evaluated. They were compared for serum levels of Free T3 (FT3), Free T4 (FT4) and TSH. The data was analyzed by SPSS software with the use of t?student, Chi?square, Independent sample T-test and Bivariate correlation test. p?0.05 was considered statistically significant.
Results: The mean age was not statistically different between two groups (p=0.297). No significant difference was observed in terms of parity between two groups (p=0.206). Normal pregnant women were not significantly different from preeclampsia cases in the view of FT3 level (1.38 pg/ml vs. 1.41 pg/ml, p=0.803), FT4 level (0.95 pg/ml vs. 0.96 pg/ml, p=0.834) and TSH level (3.51 ?IU/ml vs. 3.10 ?IU/ml, p=0.386).
Conclusion: The findings of the present study do not support the hypothesis that changes in FT3, FT4 and TSH levels could be possible etiology of preeclampsia.

Abstract

Background: Progressions in science and technology have generated several methods for delaying preterm delivery and abortion; therefore, discovering an easy, non-invasive, practical, and non-expensive predictive factor can help us to perform preventive methods in healthy pregnant women, without any risk factors.
Objective: To indicate an appropriate index for predicting abortion in early pregnancy.
Materials and Methods: In a prospective study, 73 pregnant women who had a singleton pregnancy, had no complications or history of abortion or disease, and were referred to Mahdieh and Taleghani Hospitals between 2007-2009, were evaluated. Blood and cervical fluid samples were obtained thrice from all patients: at the first visit, after 1 week, and 1-2 weeks later. They were followed up until the 12th week of gestation.
Results: Using the receiver-operator characteristic (ROC) curve analysis, 1.62 was obtained as the cut-off point for the cervical fluid: serum human chorionic gonadotropin concentration ratio; 14 patients (19.2%) experienced abortion, and 12 women (70.6%) had a ratio ≥1.62. Of the pregnant women with a ratio of <1.62, 3.6% had an abortion.
Conclusion: Pregnant women who do not show any signs of abortion and have a high cervical fluid: serum HCG concentration ratio are at risk of abortion; therefore, the cut-off point might be an appropriate index for predicting abortion in early pregnancy.

Abstract

Background: Muslim women tend to postpone their menstrual period using short course oral contraceptives (OC) during Ramadan, Muslims fasting month. Recently, many cases of stroke, particularly cerebral vein thrombosis (CVT), have been reported in Ramadan.
Objective: This work studies the incidence of CVT and its relation to Ramadan.
Materials and Methods: This is a cohort study conducted from October 2006 to October 2009 and included 4 consecutive Ramadan’s. All patients with definite diagnosis of CVT who were referred to the neurology department of Ghaem Hospital, Mashhad, Iran in this four-year period were included in the study.
Results: During the study period, 70 cases with CVT (11 males and 59 females) were recruited. Twenty five cases were admitted during Ramadan months which was significantly higher than all the other 32 months (p=1.9×10-7). The higher frequency of females (6 times more) among CVT cases probed by investigating possible risk factors and short term OC consumption was revealed as the major risk factor (p=0.00071).
Conclusion: Higher incidence of CVT in females during Ramadan suggests the presence of specific risk factors in this group. Our study revealed that short-term use of OCs may be a major risk factor for CVT.

Abstract

Background: Rupture of fetal membranes can occur at any gestational age. Premature rupture of membranes (PROM) means rupture of fetal membranes before the onset of labor.
Objective: The purpose of this study was to evaluate and compare the reliability of the vaginal washing fluid urea and creatinine for the diagnosis of PROM and to determine cut-off values.
Materials and Methods: A total of 179 pregnant women were recruited. All patients underwent different examinations. These included nitrazine paper test, fern test, amniotic fluid pooling, vaginal washing fluid urea and creatinine sampling. The one group consisted of 126 pregnant women between 14 and 41 weeks of gestation with the complaint of vaginal fluid leakage. Patients who had positive pooling, nitrazine paper test and fern test were considered as confirmed PROM group (group 1). On the other side, patients with pooling (-) and/or nitrazine paper test (-) and/or fern test (-) were taken as suspected unconfirmed PROM cases (group 2). The control group consisted of 53 pregnant women between 14 and 41 weeks of gestation without any complaint or complication. Weconducted one-way ANOVA test on the urea and creatinine measures and post-hoc comparison test. Cut-off value was determined by receiver operating characteristic (ROC) curve.
Results: Vaginal fluid concentrations of urea and creatinine were significantly different between the three groups (p<0.001). The sensitivity, specificity, positive and negative predictive values and accuracy were all 100% in detecting premature rupture of membranes by evaluation of vaginal fluid creatinine concentration with a cut-off value of 0.45 mg/dl, respectively.
Conclusion: This study demonstrates that of two markers investigated creatinine has the higher diagnostic power.

Abstract

 
Background: Tubal ectopic pregnancy (tEP) is the most common type of extra-uterine pregnancy and the most common cause of maternal mortality. Nitric oxide (NO) is a molecule that incorporates in many physiological processes of female reproductive system. Recent studies have demonstrated the possible role of endothelial isoform of nitric oxide synthase (eNOS) enzyme in the regulation of many reproductive events that occur in the fallopian tube (FT).
Objective: The aim of this study was to evaluate the expression of eNOS in the FTs of women with tEP.
Materials and Methods: In this case-control study, a total number of 30FTs samples were obtained from three groups including: 10 FTs of women that bearing an EP, 10 FTs from the non-pregnant women at luteal phase of the menstrual cycle, and 10 FTs of healthy pregnant women (n=10). Samples were fixed in 10% buffered formalin and then were evaluated by immunohistochemistry.
Results: Localization of eNOS was seen in secretory and ciliated luminal epithelium and vascular endothelium of all groups. However, we did not observed the expression of eNOS in smooth muscle cells of all groups. Expression of eNOS in luminal epithelium of women with EP compared to non-pregnant women at luteal phase of menstrual cycle and healthy pregnant group showed statistically significant increase (p=0.00). Significant difference in expression of eNOS was not observed in luminal epithelium of FTs of women at luteal phase compared to healthy pregnant groups (p=0.78).
Conclusion: This study indicates that changes in expression of eNOS in luminal epithelium of FT may lead to development of EP.

Abstract

Introduction: Regarding to the recent advances in assisted reproductive techniques (ART), twin and multiple pregnancies have increased during past years.
Objective: This study was performed to compare obstetrics and perinatal outcomes of dichorionic twin pregnancy following ART with spontaneous pregnancy.
Materials and Methods: In this cross-sectional study which was performed in Ghaem Hospital, Mashhad University of Medical Sciences, 107 dichorionic twin pregnancy were enrolled in two groups: spontaneous group (n=96) and ART group (n=31). Basic criteria and obstetrics and neonatal outcomes information including demographic data, gestational age, mode of delivery, pregnancy complications (preeclampsia, gestational diabetes, preterm labor, and intrauterine growth retardation (IUGR), postpartum hemorrhage), neonatal outcomes (weight, first and fifth minute Apgar score, Neonatal Intensive Care Unit (NICU) admission, mortality, respiratory distress, and icterus) were recorded using a questionnaire.
Results: Preterm labor, gestational diabetes, and preeclampsia were significantly higher in ART group compared to spontaneous pregnancy group. However, other factors such as anemia, IUGR, postpartum hemorrhage, and intrauterine fetal death (IUFD) were not significantly different between groups. There were no significant differences between groups in terms of neonatal outcomes (weight, 1st and 5th min Apgar score <7, NICU hospitalization, mortality, respiratory distress, and icterus).
Conclusion: With regard of significantly higher poor outcomes such as preeclampsia, gestational diabetes and preterm labor in ART group, the couples should be aware of these potential risks before choosing ART.

Abstract

Background: Clomiphene citrate is one of the effective drugs for infertilitytreatment due to oligo-ovulation or anovulation. Intrauterine insemination (IUI) isone of more adherent methods for treatment of infertile cases which is followed bycontrolled ovarian hyperstimulation (COH).
Objective: the aim of this study was to evaluate Clomiphene citrate versus letrozolewith gonadotropins in IUI cycles.
Materials and Methods: In this prospective randomized trial, 180 infertile patientswho were referred to Milad Hospital were selected. The first group received 5mg/day letrozole on day 3-7 of menstrual cycle. The second group received 100mg/day Clomiphene in the same way as letrozole. In both groups, humanmenopausal gonadotropin was administered every day starting on day between 6-8of cycle. Ovulation was triggered with urinary Human Chorionic Gonadotropin(5000 IU) when have two follicles of ≥16 mm. IUI was performed 36 hr later.
Results: The number of matured follicles, cycle cancellation, and abortion were thesame in both groups. Endometrial thickness was higher at the time of humanmenopausal gonadotropin administration in letrozole group. Chemical and clinicalpregnancy rates were much higher in letrozole group. Ovarian hyperstimulation wassignificantly higher in clomiphene group.
Conclusion: Letrozole appears to be a good alternative to clomiphene citrate withfewer side effects.

Abstract

Background: Placenta adhesive disorder (PAD) is one of the most common causes of postpartum hemorrhage and peripartum hysterectomy. The main risk factors are placenta previa and prior uterine surgery such as cesarean section. Diagnosis of placenta adhesive disorders can lead to a decrease of maternal mortality and morbidities.
Objective: The purpose of this study was to compare the accuracy of color Doppler ultrasonography and magnetic resonance imaging (MRI) in the diagnosis of PADs.
Materials and Methods:In this is cross-sectional study, Eighty-two pregnant women who were high risk for PAD underwent color Doppler ultrasound and MRI after 18 weeks of gestation. The sonographic and MRI findings were compared with the final pathologic or clinical findings. P<0.05 was considered statistically significant.
Results: Mean maternal age was 31.42±4.2 years. The average gravidity was third pregnancy. 46% of patients had placenta previa. The history of the previous cesarean section was seen in 79 cases (96%). The diagnosis of placenta adhesive disorder was found in 17 cases (21%). Doppler sonography sensitivity was 87% and MRI sensitivity was 76% (p=0.37). Doppler sonography specificity was 63% and MRI specificity was 83% (p=0.01).
Conclusion: Women with high-risk factors for PAD should undergo Doppler ultrasonography at first. When results on Doppler sonography are equivocal for PAD, MRI can be performed due to its high specificity.

Abstract

Background: Acyclovir (ACV) is known to be toxic to gonads, inducing apoptosis in the reproductive system. The beneficial effects of vitamin C (Vit C) and menthone, both as antioxidant agents on various organs has been reported.
Objective: This study evaluated the potential role of the Vit C and menthone on the DNA damage in rat spermatozoa induced by the ACV.
Materials and Methods: In this experimental study, adult male albino Wistar rats with average weight of 250±10 gr, were divided into six groups (n=18/each), as: ACV (15 mg/kg/day), ACV+Vit C (20 mg/kg/day), ACV+ menthone (100 µl/d), ACV+ menthone (250 µl/d), ACV+ menthone (400 µl/day) and control group without any treatment. At the end of experiment, the animals were sacrificed and sperm samples were collected and isolated in phosphate-buffered saline and examined by TUNEL staining process. The percentage of TUNEL positive spermatozoa was evaluated by fluorescence microscopy. Each experiment was performed in three repeats.
Results: Male rats exposed to ACV had significant increase in DNA damages in comparison to other groups. The percentage of TUNEL positive sperm cells was 90.83 (p<0.001) in ACV group. The protective role of both antioxidants used in high dose, compensate the adverse effects of the ACV. The results showed that the percentage of apoptotic sperm in the ACV+Vit C group was 16.38 (p<0.001) and in the ACV+ menthone (400 µl/d) group was 16.05 (p<0.001).
Conclusion: The present results showed that Vit C and menthone at higher dose have a good compensatory effect with significant reduction in DNA damages in sperm cells by reversing the adverse effect of ACV on the reproductive system in male rat.

Abstract

Background: Delivery is the only definite cure for hypertensive disorders. Therefore, cervical ripening and labor induction are important to achieve favorable outcomes.
Objective: This Randomized Control Trial (RCT) is aimed to compare the effects of sublingual misoprostol and Foley catheter in cervical ripening and labor induction among patients with preeclampsia or gestational hypertension.
Materials and Methods: A total number of 144 women with preeclampsia or gestational hypertention with indication of pregnancy termination, who were referred to academic hospitals of the University of Medical Sciences in Mashhad, Iran, between March 2015 and December 2016, were randomly divided into two groups. In group one (n = 72), 25 μg of misoprostol tablet was administrated sublingually every 4 hr up to six doses. In group two (n = 72), a 16F Foley catheter was placed through the internal cervical os, inflated with 60 cc of sterile saline.
Results: There were no significant differences between groups regarding the demographic characteristics, primary bishop score, and pregnancy termination indication.
The cervical ripening time (primary outcome) (8.2 vs 14.2 hr, p < 0.00), induction to delivery interval (15.5 vs 19.9 hr, p < 0.00), and vaginal delivery before 24 hr (63.9% vs 40%, p = 0.03) were significantly different between the two groups. There was no significant difference between groups in view of oxytocin requirement (p = 0.12), neonatal Apgar score (p = 0.84), or neonatal intensive care unit admission (p = 78).
Conclusion: This trial showed that the application of sublingual misoprostol, compared to the Foley catheter, can reduce cervical ripening period and other parameters related to the duration of vaginal delivery. This misoprostol regimen showed inconsiderable maternal complications.

Abstract

Background: Apigenin is a plant-derived flavonoid with antioxidative and antiapoptotic effects. Bone marrow stromal cells (BMSCs) are a type of mesenchymal stem cells (MSCs) that may recover damaged ovaries. It seems that apigenin may promote the differentiation of MSCs.
Objective: The aim of this study was to investigate the effect of coadministration of apigenin and BMSCs on the function, structure, and apoptosis of the damaged ovaries after creating a chemotherapy model with cyclophosphamide in rat.
Materials and Methods: For chemotherapy induction and ovary destruction, cyclophosphamide was injected intraperitoneally to 40 female Wistar rats (weighing 180–200 gr, 10 wk old) for 14 days. Then, the rats were randomly divided into four groups (n = 10/each): control, apigenin, BMSCs and coadministration of apigenin and BMSCs. Injection of apigenin was performed intraperitoneally and BMSC transplantation was performed locally in the ovaries. The level of anti-mullerian hormone serum by ELISA kit, the number of oocytes by superovulation, the number of ovarian follicles in different stages by H&E staining, and the expression of ovarian Bcl-2 and Bax proteins by western blot were assessed after four wk.
Results: The results of serum anti-mullerian hormone level, number of oocytes and follicles, and Bcl-2/Bax expression ratio showed that coadministration of apigenin and BMSCs significantly recovered the ovarian function, structure, and apoptosis compared to the control, BMSC, and apigenin groups (p < 0.001).
Conclusion: The results suggest that the effect of coadministration of apigenin and BMSCs is maybe more effective than the effect of their administrations individually on the recovery of damaged ovaries following the chemotherapy with cyclophosphamide in rats.
