Diagnostic accuracy of real‐time 3D sonography in the diagnosis of congenital Mullerian anomalies in high‐risk patients with respect to the phase of the menstrual cycle

To compare the diagnostic accuracy of 2‐dimensional sonography (2DUS) and real‐time 3‐dimensional sonography (3DUS) in the diagnosis of congenital mullerian defects (CMD) with respect to the phase of the menstrual endometrium.

Three-dimensional ultrasonographic diagnosis and hysteroscopic management of a viable cesarean scar ectopic pregnancy.

Implantation of conception material within a cesarean section scar is an extremely rare form of ectopic pregnancy with devastating complications, such as uterine rupture and intractable bleeding. Both 2‐D and 3‐D transvaginal ultrasonographic devices are used adequately for precise diagnosis, but there is still a lack of consensus concerning management strategies. No therapeutic modality is suggested to be entirely efficacious and safe for preserving uterine integrity. We present here a 29‐year‐old woman with vaginal bleeding and a gestational sac with a viable embryo of 6 weeks of age that was implanted in a cesarean section scar. Serum β‐hCG levels were 16 792 mIU/mL. Following an unsuccessful treatment course of systemic methotrexate, the patient underwent operative hysteroscopy. Minimally invasive hysteroscopic resection of the ectopic gestational mass without major complication appears to be an alternative therapeutic approach with minimal morbidity and preservation of future fertility.

Effect of follicular fluid NO, MDA and GSH levels on in vitro fertilization outcomes.

OBJECTIVE To investigate the biochemical markers such as nitric oxide (NO), malondialdehyde (MDA) and reduced glutathione (GSH), indicators of the oxidative status of the follicle, to predict the outcome of in vitro fertilization. MATERIAL AND METHODS Follicular aspirates of dominant follicles were collected during oocyte retrieval. Biochemical analyses of NO, MDA and GSH were performed on all aspirates. RESULTS When the successful and unsuccessful pregnancy groups were compared in terms of NO, MDA and GSH, follicular fluid MDA was significantly higher (p=0.001) and follicular fluid NO level was significantly lower (p=0.039) in the pregnant group. Correlation analysis between oxidative stress and IVF parameters showed that MDA had a positive weak correlation with the number of grade 1 embryos (r=0.271, p=0.033) and fertilization rate (r=0.263, p=0.039). ROC curve analysis found that malondialdehyde has an area under the curve of 0.74 and can predict pregnancy with high sensitivity. CONCLUSION As malondialdehyde was significantly different in pregnant and non-pregnant women and had a good sensitivity profile in predicting pregnancy, it may be considered a marker for predicting IVF success.

Malignant Struma Ovarii: A Case Report

We present a case of a 40-yr-old woman diagnosed with a primary malignant struma ovarii. The patient was admitted with the complaint of pelvic pain and a large pelvic mass in the mid-portion of lower abdomen on gynecological examination. Pre-operative tumor markers and routine biochemistry were unremarkable. She was treated with total abdominal hysterectomy and right salpingo-oopherectomy. Post-operatively, she was diagnosed with a malignant struma ovarii through the usage of histopathological criteria similar to the guidelines for primary thyroid gland disease. The patient was subsequently performed left salpingo-oopherectomy and retroperitoneal pelvic lympadenectomy for re-staging. Although, left ovary and lymph nodes were histopathologically normal, she was offered thyroidectomy but she refused to accept the offer. Thyroglobulin level was monitored in the post-operative period. She is free of the disease for 18 months.

Prospective case control comparison of fetal intrapartum oxygen saturations during epidural analgesia.

BACKGROUND The purpose of this study was to compare fetal oxygen saturation by fetal pulse oximetry in parturients with and without epidural labor analgesia in a prospective case control study. METHODS Fetal oxygen saturation values were compared in term pregnant women who received epidural analgesia (epidural group) with those in women who did not (control group). Mode of delivery, Apgar score, fetal oxygen saturation, cord blood gas analysis and fetal outcomes were also compared. RESULTS A total of 150 pregnant women (75 in each group) gave written consent and were enrolled. The average fetal oxygen saturation during the first stage of labor (active phase) was 45.6 +/- 8.1% for the epidural group and 45.9 +/- 7.4% for the control group (NS); saturations for the second stage of labor were 44.9 +/- 8.8% and 45.3 +/- 6.7%, respectively (NS). In the epidural group, the duration of the first stage of labor was significantly longer (565 +/- 217 min) than the control group (434 +/- 222 min; P= 0.001). Cesarean delivery rates, neonatal cord blood gas analysis, Apgar scores, and neonatal outcomes were similar in the two groups. CONCLUSIONS Fetal oxygen saturation values are similar in the first and second stage of labor in the presence or absence of epidural labor analgesia.

Hormonal and functional biomarkers in ovarian response

PurposeSuccess rates of any artificial reproduction techniques depend on a correct protocol for ovarian stimulation. This can be decided only by proper assessment of ovarian reserve before commencing ovarian stimulation. This study has been conducted to investigate the role of hormonal and functional biomarkers in the prediction of ovarian response.MethodsA total of 689 women between July 2012 and July 2013 undergoing IVF at Kocaeli University have been enrolled in the study. Patients have been categorized into three groups according to the number of oocytes retrieved: 0–3 oocytes (poor responders), 4–15 oocytes (normoresponders), and >16 oocytes (hyperresponders). Groups have been compared according to follicle-stimulating hormone (FSH), E2, luteinizing hormone (LH) levels, antral follicle counts, and E2 levels on hCG days. Furthermore, regression analysis has been performed with parameters such as age, FSH, LH, E2, anti-mullerian hormone (AMH) and antral follicle counts (AFC) that can affect the total number of oocytes retrieved and pregnancy rates and their interactions with each other have been investigated.ResultsFSH, age, hCG day LH level, cycle cancellation rate, total gonadotropin dose were significantly higher in the poor responder group, but in this group, AFC, AMH, hCG day E2 level, and the number of MII oocytes were significantly lower. Cut-off values of normal responders for FSH, AMH, and AFC were 8.43 area under curve [AUC: 0.541 (0.491–0.590)], 0.62 [AUC: 0.704 (0.638–0.764)], and 6 [AUC: 0.715 (0.667–0.760)], respectively. Cut-off values for the absolute poor response group (cycle cancellation) were 12.75 for FSH [AUC: 0.533 (0.49–0.57)], 0.23 for AMH [AUC: 0.678 (0.618–0.733)], and 6 for AFC [AUC: 0.576 (0.531–0.613)]. AMH and AFC were the best markers for the prediction of total oocyte count, independent of age, FSH, and LH levels.ConclusionsAMH and AFC were found to be the best ovarian reserve tests that can determine the total oocyte count retrieved, without any significant effects on pregnancy rates.

Spontaneous Rupture of Uterine Vein in Twin Pregnancy

Objective. Aim of our study is to present a case of a twin pregnancy following invitro fertilization cycle complicated with hemoperitoneum at third trimester. Case. A 26-year-old nulliparous pregnant woman at 32 weeks of gestation with twin pregnancy following invitro fertilization cycle complained of abdominal pain. After 48 hours of admission, laparotomy was performed with indications of aggravated abdominal pain and decreased hemoglobin levels. Utero-ovarian vein branch rupture was detected on the right posterior side of uterus and bleeding was stopped by suturing the vein. Etiopathogenesis of the present case still remains unclear. Conclusion. Spontaneous rupture of the uterine vessels during pregnancy is a rare complication and may lead to maternal and fetal morbidity and mortality. Diagnosis and treatment are based on the clinical symptoms of acute abdominal pain and laboratory tests of hypovolemic shock signs.

The Role of Overweight and Obesity in In Vitro Fertilization Outcomes of Poor Ovarian Responders.

Objective. Obesity is a worldwide concern with detrimental health effects including decreased fecundity. However, obesitys impact on in vitro fertilization (IVF) is inconclusive and there is little data concerning poor ovarian responders (POR). This study explored the effects of overweight and obesity on IVF outcomes of POR. Design. We retrospectively evaluated 188 POR undergoing IVF cycles. Methods. Patients were categorized into three groups. Group 1 was normal weight POR (18.5–24.9 kg/m2, n = 96); Group 2 was overweight POR (25.0–29.9 kg/m2, n = 52); and Group 3 was obese POR (≥30.0 kg/m2, n = 40). Main measured outcomes included IVF outcomes. Results. The oocyte maturity, total gonadotropin dose-duration, and cycle cancellation rates were similar. Obese women had significantly decreased LH levels. LH < 4 mIU/mL had a sensitivity (62%) and a specificity (86%) for IVF failure (AUC: 0.71). Fertilization rates of obese subjects were significantly lower than normal and overweight subjects (p = 0.04). Obese womens clinical pregnancy rates were significantly lower (15%) than normal weight women (33.3%, p = 0.01). Conclusions. Despite similar counts of recruited mature oocytes, obese POR women had decreased fertilization and clinical pregnancy rates. Obesity rather than overweight significantly decreased IVF outcomes in POR.

Prenatal Diagnosis of Cantrell’s Pentalogy Associated with Agenesis of Left Limb in a Twin Pregnancy

Pentalogy of Cantrell is a rare malformation described in the literature. We report a case of pentalogy of Cantrell associated with left limb deficiency in a twin pregnancy. The fetus with multiple anomalies revealed kyphosis, ectopia cordis, and a large defect with protruding liver and bowel loops at 12 weeks and 3 days of gestational age on ultrasound scan. The other fetus was ultrasonographically normal. We diagnosed a case of pentalogy of Cantrell in a twin pregnancy after exclusion of limb body wall complex, body stalk anomaly, and amniotic band syndrome and after delivery of the fetuses. Macroscopic examinations were ectopia cordis, extrusion of the abdominal organs without membranes surrounding, and agenesis of the left limb.

Cranial thromboembolism secondary to patent foramen ovale and deep venous thrombosis after cesarean section.

Background: Paradoxical embolism via a patent foramen ovale (PFO) is a rare event in the puerperium as a cause of stroke. Case: We report a 21-year-old, G4P3A1 woman with the symptoms of convulsion, stroke and unconsciousness 1 week after cesarean delivery. An infarction was detected in both frontal lobes, and echocardiography and MRI confirmed the PFO. Her follow-up course with low-molecular-weight heparin and then warfarin for 6 months was uneventful. Conclusion: Patients with an unexplained arterial event should be screened for PFO and possible paradoxical embolism.
