OBJECTIVE: The aim of this study was to compare the efficacy of intravenous iron to oral iron in the treatment of anemia in pregnancy. METHODS: In this randomized open-label study, 90 women with hemoglobin levels between 8 and 10.5 g/dL and ferritin values less than 13 &mgr;g/L received either oral iron polymaltose complex (300 mg elemental iron per day) or intravenous iron sucrose. The iron sucrose dose was calculated from the following formula: weight before pregnancy (kg) × (110 g/L – actual hemoglobin [g/L]) × 0.24 + 500 mg. Treatment efficacy was assessed by measuring hemoglobin and ferritin on the 14th and 28th days and at delivery, and the hemoglobin on the first postpartum day. Adverse drug reactions, fetal weight, hospitalization time, and blood transfusions were also recorded. RESULTS: Hemoglobin values varied significantly with time between groups (interaction effect, P < .001). The change in hemoglobin from baseline was significantly higher in the intravenous group than the oral group at each measurement; the changes with respect to subsequent hemoglobin were significantly higher on the 14th (P = .004) and 28th (P = .031) days. Ferritin values were higher in patients receiving intravenous iron throughout pregnancy. No serious adverse drug reactions were observed. Fetal weight and hospitalization time were similar in the 2 groups. Blood transfusion was required for only one patient in the oral group. CONCLUSION: Intravenous iron treated iron-deficiency anemia of pregnancy and restored iron stores faster and more effectively than oral iron, with no serious adverse reactions. LEVEL OF EVIDENCE: I

OBJECTIVE: The aim of this study was to evaluate the diagnostic accuracy of random urine protein-creatinine ratio for prediction of significant proteinuria (≥ 300 mg/24 h) in patients with new-onset mild hypertension in late pregnancy. METHODS: Medical records of 185 consecutive pregnant patients with new onset of mild hypertension in late pregnancy were reviewed. Random urine samples were taken before 24-hour urine collection. The predictive values of the random urine protein-creatinine ratio for diagnosis of significant proteinuria were estimated by using at least a 300-mg protein level within the collected 24-hour urine as the gold standard. RESULTS: Thirty-nine patients (21%) had significant proteinuria. There was a significant association between 24-hour protein excretion and the random urine protein-creatinine ratio (rs = 0.56, P < .01). With a cutoff protein-creatinine ratio greater than 0.19 as a predictor of significant proteinuria, sensitivity and specificity were 85% and 73%, respectively. Positive and negative predictive values of the test were 46% and 95%, respectively. CONCLUSION: The random urine protein-creatinine ratio was a poor predictor for significant proteinuria in patients with new-onset mild hypertension in late pregnancy. LEVEL OF EVIDENCE: II-3

Acute mesenteric venous thrombosis is a rare and potentially fatal disease, which often occurs in medically compromised elderly patients. Isolated mesenteric venous thrombosis may be encountered in young women who have underlying hypercoagulable disease. We report a case of mesenteric venous thrombosis in a young pregnant woman in whom protein S deficiency was diagnosed at a later stage. The patient underwent extensive bowel resection. On follow‐up she had developed an obstruction on the intestinal anastomosis. The anastomosis was revised, but the patient died of intervening complications 3 months after the operation. Early management of acute mesenteric venous thrombosis relies on early diagnosis, which requires a high index of suspicion. The condition must be considered during evaluation of persistent abdominal pain in pregnant women with hypercoagulable disorder.

Laryngeal atresia is one of the rarest congenital malformations.1 This anomaly is one of the etiologic factors causing congenital laryngeal high airway obstruction syndrome. According to Smith and Bain, 2 laryngeal atresia is classified into 3 types. Type 1 is complete atresia of the larynx with a combination of midline fusion of arytenoid cartilage and intrinsic muscles. Infraglottic obstruction is called type 2 and is characterized by dome-shaped cricoid cartilage obstructing the lumen. Type 3 is occlusion of the anterior fibrous membrane and fusion of the arytenoid cartilage at the level of the vocal processes. 2 Types 1 and 2 are mostly accompanied by other congenital defects. 3 Antenatal sonographic diagnosis at early gestational weeks is desired because the disease is generally incompatible with life, although only a few cases treated with neonatal interventions such as ex utero intrapartum treatment (EXIT) have been reported. 4-6 We describe a case of laryngeal atresia that was prenatally diagnosed at 19 gestational weeks with the sonographic findings of a dilated trachea, hyperechoic lungs, pleural effusion, and minimal fetal abdominal ascites and for which the pregnancy was terminated at 22 gestational weeks.

Angiomyofibroblastoma of the vulva during pregnancy

Kadir Cetinkaya; Ragip Atakan Al; Nesrin Gürsan

Angiomyofibroblastoma is a rare, benign and recently defined soft tissue tumor. It generally arises from superficial soft tissues, especially from mesenchymal cells in the subepithelial myxoid stromal zone of the vulvovaginal region. The tumor is usually positive for estrogen and progesterone receptor. We report a pregnant woman who developed vulvar angiomyofibroblastoma within 2 months. The tumor was negative for estrogen and progesterone receptor.

Objectives: In this study, we investigated the effect of metamizole on ischemia/reperfusion (I/R) injury an analysis of biochemistry, molecular gene expression, and histopathology in the rat ovary of female albino Wistar rats. Materials and Methods: Animals were divided into four groups; control group with induced ischemia-reperfusion (IRC), ischemia-reperfusion +100 mg/kg metamizole sodium (MS) (IRM-100), ischemia-reperfusion +200 mg/kg MS (IRM-200), and healthy group applied sham operation (SG). Results: Myeloperoxidase (MPO) activity and gene expression increased significantly in IRC and IRM-100 group rat ovarian tissue compared with the SG group (P < 0.0001). However, MPO activity and gene expression in IRM-200 group ovarian tissue decreased significantly compared with the IRC and IRM-100 groups (P < 0.0001). Histopathologically, pronounced congestion, dilated vessels, hemorrhage, edema, degenerative cells, and neutrophil migration and adhesion to the endothelium were observed in the IRC and IRM-100 group ovarian tissues. A small number of congested dilated vessels, mild congestion, and edema were observed in the IRM-200 group, but no neutrophil migration and adhesion to the endothelium or degenerative cells. Conclusions: At 200 mg/kg dose metamizole prevented ovarian injury induced with I/R. This data show that metamizole can be used in the ovarian I/R injury treatment.

Vaginal Misoprostol Compared With Buccal Misoprostol for Termination of Second-Trimester Pregnancy: A Randomized Controlled Trial.

Ragip Atakan Al; Omer Erkan Yapca

OBJECTIVE: To compare the efficacy of vaginal misoprostol with buccal misoprostol for second-trimester termination of pregnancies. METHODS: In a randomized trial, we compared 400 micrograms vaginal and buccal misoprostol every 3 hours for up to six doses for induction of labor at 13–24 weeks of gestation with a live fetus and intact membranes. Women who had a uterine scar were excluded from the study. The primary outcome of the study was induction-to-abortion interval. Based on a two-tailed &agr; of 0.05, we planned to include 65 patients per group to detect a 50% difference in the primary outcome with a power of 80%. RESULTS: From January 2014 to December 2014, 172 women were screened and 130 were randomized: 65 vaginal and 65 buccal misoprostol. Characteristics of patients were similar between groups. Patients administered vaginal misoprostol compared with buccal misoprostol had a shorter induction-to-abortion interval (25±17 hours compared with 40±29 hours, P=.001) and a higher abortion rate within both 24 hours (41 [63%] compared with 27 [42%] P=.014) and 48 hours (59 [91%] compared with 44 [68%], P=.001). Complete abortion rates were similar in both groups (vaginal 51 [78%] compared with buccal 54 [83%]). The incidence of side effects was similar for both groups. The perceived pain was higher in the buccal group, but the small difference did not appear to be clinically meaningful. CONCLUSION: Vaginal compared with buccal misoprostol administration has a shorter induction-to-abortion interval for second-trimester termination of viable pregnancies. However, both administration routes are equally effective for induction of termination. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, www.clinicaltrials.gov, NCT02048098. LEVEL OF EVIDENCE: I

Gulsah Aynaoglu Yildiz; Omer Erkan Yapca; Ragip Atakan Al; Metin Ingec

We have interestedly read the article written by Thalia Wong BS in July 2015, which is about Pediatric Blood Cancer, including clinical findings and results of infants <1 year of age with Ewing sarcoma. We report a case with congenital Ewings sarcoma that easily interfered with rabdomyosarcoma in a pregnant woman. A 32-year-old multigravida with a big neck mass at 35 weeks was referred to our clinic. The final diagnosis of extraskeletal Ewings sarcoma was made. Hepatic metastasis was detected and treatment by chemotherapy was initiated. Ewings sarcoma is usually noted among adolescents or young adults and more rarely than among newborns. This case is important because of its rarity.

Fetus delivery time in extraperitoneal versus transperitoneal cesarean section: a randomized trial

Omer Erkan Yapca; Yunus Emre Topdagi; Ragip Atakan Al

Abstract Objective: We compared the extraperitoneal cesarean section to transperitoneal cesarean on fetal delivery time. Material and methods: This randomized study included 210 pregnant women undergoing cesarean section for elective reasons, repeat cesarean (< four), or dystocia. Patients who required an urgent cesarean section, who were at high risk for obstetric or maternal bleeding, who had a uterine or adnexal mass, or who requested tubal ligation were excluded from the study. The primary outcome of the study was the skin incision-to-delivery time. The sample size was set to detect of 1-minute difference in fetal delivery time between groups (two-tailed hypothesis, αu2009=u20090.05, βu2009=u20090.10). Secondary outcome measures were total operation time, intraoperative nausea, gag reflex, vomiting, pain and anxiety for those receiving regional anesthesia, postoperative pain, change in hemoglobin, postoperative analgesic requirements, nausea, vomiting and shoulder pain, urogenital distress, time until gas passage, and neonatal outcome. Results: No significant difference occurred between the two groups for skin incision-to- delivery time (extraperitoneal cesarean 3.9u2009minutes [2.1–7.3] versus transperitoneal cesarean 4.2u2009minutes [1.9–8.2], pu2009=u2009.065). Significant differences regarding intraoperative pain, total operation time, postoperative pain at the surgical site and shoulder pain, analgesic requirements, time until gas passage, and oral tolerability favored the extraperitoneal group. No significant differences between groups occurred regarding other seconder outcome parameters. Conclusions: There is no clinically significant difference between extraperitoneal cesarean section and transperitoneal cesarean on fetal delivery time. Extraperitoneal cesarean reduces postoperative pain, analgesic requirements, and improves oral tolerability.
