Item Endometrial fluid in postmenopausal women(John Wiley and Sons Ltd, 2009) Inceboz U.; Uyar Y.; Baytur Y.; Kandiloglu A.R.[No abstract available]Item Comparative effects of risedronate, atorvastatin, estrogen and SERMs on bone mass and strength in ovariectomized rats(2009) Uyar Y.; Baytur Y.; Inceboz U.; Demir B.C.; Gumuser G.; Ozbilgin K.Objective: The aim of this study was to investigate bone protective effects of risedronate, atorvastatin, raloxifene and clomiphene citrate in ovariectomized rats. Methods: Our study was conducted on 63 rats at Experimental Research Center of Celal Bayar University. Six-month-old rats were divided into seven groups. There were five drug administered ovariectomized groups, one ovariectomized control group without drug administration and one non-ovariectomized control group without drug administration. Eight weeks postovariectomy, rats were treated with the bisphosphonate risedronate sodium, the statin atorvastatin, the estrogen 17β-estradiol and the selective estrogen receptor modulators (SERMs) raloxifene hydrochloride and clomiphene citrate by gavage daily for 8 weeks. At the end of the study, rats were killed under anesthesia. For densitometric evaluation, left femurs and tibiae were removed. Left femurs were also used to measure bone volume. Right femurs were used for three-point bending test. Results: Compared to ovariectomized group, femur cortex volume increased significantly in non-ovariectomized group (p = 0.016). Compared to non-ovariectomized group, distal femoral metaphyseal and femur midshaft bone mineral density values were significantly lower in ovariectomized group (p = 0.047). In ovariectomy + atorvastatin group, whole femur and femur midshaft bone mineral density and three-point bending test maximal load values were significantly higher than ovariectomized group (p = 0.049, 0.05, and 0.018). When compared to the ovariectomized group, no significant difference was found with respect to femoral maximum load values in groups treated with risedronate, estrogen, raloxifene and clomiphene (p = 0.602, 0.602, 0.75, and 0.927). In ovariectomy + risedronate group, femur midshaft bone mineral density values were significantly higher than the values in ovariectomized group (p = 0.023). When compared to ovariectomized group, no significant difference was found with respect to femur midshaft bone mineral density values in groups treated with estrogen, raloxifene and clomiphene (p = 0.306, 0.808, and 0.095). Conclusions: While risedronate sodium prevented the decrease in bone mineral density in ovariectomized rats, atorvastatin maintained mechanical characteristics of bone and also prevented the decrease in bone mineral density as risedronate sodium. © 2009 Elsevier Ireland Ltd.

Methods: Body mass index, cervical length, dilatation, effacement, Bishop score, parity, maternal age and birth weight were evaluated in 189 singleton pregnant women at 37-42 weeks of gestation and having induction of labor. All underwent induction of labor with oxytocin. Body mass index was calculated using the formula weight (kg)/height2 (m), cervical measurement was performed by transvaginal ultrasonography and Bishop score was determined by digital examination of cervix. Results: Logistic regression analysis indicated that the cervical length and body mass index were independent variables in determining the risk of cesarean section (OR = 1.206, P = 0.000, CI 95% = 1.117-1.303; OR = 1.223, P = 0.007, CI 95% = 1.058-1.414 respectively). In multiple linear regression analysis, the effect of cervical length and body mass index on induction delivery interval was found to be statistically significant (t = 5.738, P = 0.000; t = 2.680, P = 0.009, respectively). ROC curve showed that the best parameter in predicting the risk of cesarean section was cervical length and that cervical length and body mass index were better parameters compared to the Bishop score (the areas under the curve are 0.819, 0.701 and 0.416, respectively). Conclusions: Body mass index and transvaginal cervical length were better predictors compared to the Bishop score in determining the success of labor induction. © 2009 Springer-Verlag.Item Prevalence of fetal malnutrition and relationship between fetal malnutrition and fetal acidemia; [Fetal malnütrisyonun sikliǧi ve fetal asidemi ile olan i̇lişkisi](2012) Tanriverdi S.; Karaboǧa B.; Karaca Ö.; Baytur Y.Objective: The aim of this study is determining prevalence of fetal malnutrition and relationship between fetal malnutrition and fetal acidemia at term newborn infants. Material and Methods: This study was performed on 121 term newborn infants who were born at the Department of Gynecology and Obstetrics, between September 2010 and May 2011. Fetal malnutrition was diagnosed using [Clinical Assessment of Fetal Nutritional Status Scoring (CANSCORE)] within 12 hours after birth and umblical artery blood-gas analysis was performed at birth. Results: Mean value of CANSCORE was 27.6±3.5 (18-44) at term newborn infants. CANSCORE score was determined as 24 and less in 12 (9.9%) infants who were evaluated as having fetal malnutrition. CANSCORE score was above 24 in other 109 (90.1%) infants. Ten of the 12 newborn infants with fetal malnutrition were [small for gestational age (SGA)]. There was no relationship between fetal malnutrition and low CANSCORE (P=0.000). The mean value of pH was 7.30±0.07 (7.01-7.41) at umblical artery blood-gas analysis. Fetal acidemia (pH<7.15) was observed in 8 (6.6%) infants. There was no significant relationship between the presence of fetal malnutrition and fetal acidemia (p=0.735). Conclusion: No relationship between fetal malnutrition and fetal acidemia was observed in this study.

Heteropagus twinning (parasitic twinning) is a specific and much rarer form of conjoined twinning. In this anomaly, while one of the twins (host twin) develops completely, the other one develops asymmetrically attached to and dependent upon the host (parasitic twin). Number of conjoined twins antenatally diagnosed as heteropagus is considerably few in the literature. Accurate antenatal diagnosis can be helpful to inform the family in the decision to terminate or continue with pregnancy. Antenatal three-dimensional sonography provides an accurate diagnosis and recognition of the details of the anomaly better. In this paper, a case that was diagnosed with epigastric heteropagus twinning with three-dimensional ultrasonography at 17 weeks of gestation with a successful separation with surgery is presented. © 2012 by Türkiye Klinikleri.Item Bladder carcinoma in pregnancy: Unusual cause for frequent urinary tract infection - Case report(2013) Muezzinoglu T.; Inceboz U.; Baytur Y.; Nese N.[No abstract available]Item Prenatal diagnosis of placenta percreta with ultrasound(Aras Part Medical International Press, 2014) Ulkumen B.A.; Pala H.G.; Baytur Y.The incidence of the placental invasion anomalies are increasing, mainly due to repeat cesarean deliveries. Placenta percreta occurs if these villi perforate the serosa and also sometimes into adjacent organs such as the bladder. The prenatal diagnosis is very important because of the high maternal morbidity and mortality rates without the appropriate surgical planning. The adherent placentas will result in severe early postpartum bleeding, just after the delivery of the fetus. Severe hemorrhage usually results rapidly in disseminated intravascular coagulation (DIC), shock, multiorgan failure or death.The surgery is also challenging due to the risk of the adjacent tissue damage, such as bladder or ureteral injury. Approximately 1 in every 3 cases need intensive care. We present here a prenatally diagnosed, 31-year-old gravida 7 para 2 abortus 4 pregnant case with placenta percreta and rewiev the relevant literature about the key aspects in the ultrasonograhic diagnosis and underlie the key points in the diagnosis. © 2014 The Author(s).Item Acute abdomen and massive hemorrhage due to placenta percreta leading to spontaneous uterine rupture in the second trimester(Saudi Arabian Armed Forces Hospital, 2014) Ulkumen B.A.; Pala H.G.; Baytur Y.Placental invasion anomalies are rare obstetrical complications. They cause severe third trimester hemorrhage, severe postpartum bleeding, and maternal morbidity and mortality unless they are diagnosed antenatally. We present a rare case with placenta percreta leading to spontaneous uterine rupture during the second trimester with an acute abdomen and hypovolemia. © 2014, Saudi Arabian Armed Forces Hospital.

Twenty-one (77.7%) patients diagnosed either as omphalocele or limb body wall defect were offered karyotype analysis; 11 (52.4%) of them accepted the intervention, and 2 of the 11 patients (18.2%) had abnormal karyotype. Regarding the omphalocele cases; 12 (66.6%) cases had isolated omphalocele, whereas 6 of the 18 cases (33.3%) had associated anomalies. Expectant management was performed in 8 (66.7%) of 12 isolated omphalocele cases. Two of the isolated omphalocele group (16.7%) had missed abortion, the other 2 (16.7%) had termination of the pregnancy because of the associated chromosomal anomaly (47,XXY and 45,X0). Three of the gastroschisis group (50%) had missed abortion, and the other 3 (50%) had expectant management with cesarean delivery between 38-39 gestational weeks. Cases with limb body wall defect were terminated due to the lethal condition. © 2014, Saudi Arabian Armed Forces Hospital.

The neonates were classified according to method of delivery and anesthetic agents as group A (cesarean section/general anesthesia with sevoflurane), group B (cesarean section/ spinal anesthesia with bupivacaine hydrochloride), group C (vaginal delivery with episiotomy/local anesthesia with prilocaine hydrochloride) and group D (vaginal delivery/ no anesthesia). The levels of neonatal serum bilirubin in the groups were compared.; Results: There was no difference between group A and group B in terms of neonatal bilirubin levels (p = 0.98). Depending on the use of prilocaine hydrochloride as local anesthetic agent in the vaginal delivery, there was no significant difference between the groups C and D, in terms of the neonatal bilirubin levels (p = 0.99). The serum levels of bilirubin in cesarean section groups were significantly higher than those of the vaginal delivery groups (p<0.001).; Conclusion: Prilocaine hydrochloride used for episiotomy did not exert any effects on neonatal hyperbilirubinemia. However, cesarean section with sevoflurane and bupivacaine hydrochloride seemed to result in increased bilirubin levels. © 2014 / PMCARAS . All rights reserved.
