N.; TOPRAK A.; ÇETİN Ç.; KÜTÜK M. S.; TAKMAZ, TAHA; ARICI HALICI, BELFİN NUR; TOPRAK, ALİ; ÇETİN, ÇAĞLAR; KÜTÜK, MEHMET SERDAR© 2022, Duzce University Medical School. All rights reserved.Aim: The aim of this study was to determine the diagnostic accuracy of different urine dipstick protein threshold levels in predicting the presence of abnormal proteinuria in pregnant women with hypertension. Material and Methods: A total of 326 singleton pregnant women who underwent 501 urine protein tests and who had suspected preeclampsia were included in this retrospective study. Patient data was taken including medical and obstetric history. The results of dipstick urinalysis and concurrent 24-hour urine protein excretion measurements were compared to determine the accuracy of urinalysis. Results: A dipstick result of 1+ was found to be the best cut-off to predict 500 mg of protein excretion per day, with sensitivity and specificity of 62.09% and 88.97%, respectively. A 2+ proteinuria dipstick cut-off had high specificity and positive predictive value (PPV) (99.05% and 98.84%, respectively) for the prediction of 300 mg of protein excretion per day; this cut-off had low sensitivity (21.46%). A cut-off of 1+ also provided satisfactory specificity and PPV (91.43% and 94.48%, respectively) for the detection of 300 mg of protein excretion per day, but sensitivity was compromised (38.89%). Among 301 patients with negative dipstick results, 212 had a 24-hour urine protein extraction greater than 300 mg, with a false negative rate of 70.43%. Conclusion: The results suggest that the urine protein dipstick measurement has limited quantitative ability for the prediction of abnormal proteinuria. Additionally, the use of 500 mg 24-hours protein excretion as a cut-off value for abnormal proteinuria may provide useful data.
- PublicationMetadata onlyPrenatal Sonographic Detection of Monochorionic Twins with Bipartite Placenta(2020-02-10T04:00:00Z) KÜTÜK, MEHMET SERDAR; TAKMAZ, TAHA; Bayram, Arslan; Ozturk, Sule; KÜTÜK, MEHMET SERDAR; TAKMAZ, TAHABackground: Determination of placentation and amnionicity is important for antenatal and intrapartum management in twin gestations. We present an typical monozygotic twin placenta and underscore the sonographic features and diagnostic pitfalls that may interfere with antenatal diagnosis. Case report: A 35-year-old G4P2 with a spontaneous pregnancy applied for routine second trimester anomaly screening. Upon prenatal ultrasonography at 20 weeks, an anatomically normal, same sex twin pregnancy was detected. A thin dividing membrane and a T-sign suggestive of a monochorionic diamniotic pregnancy were visualized. Antenatal follow-up was uneventful. Cesarean delivery was performed at 37 week. Postpartum examination revealed two distinct placental discs connected with each other through membranes. Microscopic examination of the membranes supported monochorionicity. Short Tandem Repeat Profile Analysis revealed identical pattern and confirmed monozygosity. Conclusion: Two separate placentas with a T-sign in same-sex twins should raise the suspicion of monozygosity, and should be followed accordingly.

- PublicationUnknownEvaluation of Anxiety in Turkish Parents of Newborns with Cleft Palate with or Without Cleft Lip(2023-01-01) SUNAL AKTÜRK E.; ŞEKER E. D.; ÇAPKIN D.; KÜTÜK M. S.; SUNAL AKTÜRK, EZGİ; ŞEKER, ELIF DILARA; ÇAPKIN, DUYGU; KÜTÜK, MEHMET SERDAR© 2023, American Cleft Palate Craniofacial Association.Objective: (1) To compare anxiety between parents of newborns with cleft lip and palate (CLP), isolated cleft palate (CP), and healthy newborns and (2) to evaluate anxiety between parental dyads within these groups. Design: A cross-sectional study. Setting: University Hospital. Participants: Surveys were completed by 20 mothers and 20 fathers of newborns with CLP, 21 mothers and 21 fathers of newborns with CP, and 23 mothers and 23 fathers of healthy newborns (controls). Main Outcome Measure: The State-Trait Anxiety Inventory (STAI) assessed parental anxiety. Mothers of newborns with a cleft reported on concerns regarding cleft-related issues and facial appearance. Results: State and trait anxiety were generally in the moderate range for parents of newborns with a cleft, while control parents had low state anxiety and moderate trait anxiety. Mothers of newborns with CP and CLP had significantly higher state and trait anxiety levels than control mothers (p <.05). Fathers of newborns with CLP had a higher state anxiety level than control fathers. When maternal and paternal anxiety was compared within the groups, only trait anxiety scores were significantly higher in mothers of newborns with CLP than that of fathers (p <.05). More than half of mothers of newborns with a cleft were concerned about their newborn\"s feeding, speech, and palate. Conclusions: Parents of children with a cleft may need psychological support in the early postnatal period. It is important for neonatal cleft team providers to help reduce parental anxiety and educate families about cleft care, with a focus on feeding.

- PublicationUnknownThe effects of maternal smoking on fetal cranial development. Findings from routine midtrimester sonographic anomaly screening(2023-12-01) ÇETİN Ç.; BAKAR R. Z.; Takmaz T.; PASİN Ö.; KÜTÜK M. S.; ÇETİN, ÇAĞLAR; BAKAR, RABIA ZEHRA; PASİN, ÖZGE; KÜTÜK, MEHMET SERDARThe aim of this study was to assess the effect of continued smoking before and during pregnancy on mid-trimester fetal head development. A total of 250 pregnant women enrolled in the study. All participants were confirmed to be smokers or non-smokers by verifying breath carbon monoxide readings. Biparietal diameter (BPD), head circumference (HC), lateral ventricle (LV), and cisterna magna (CM) were evaluated by ultrasound between 20-22 weeks of pregnancy. Gender and gestational age-adjusted BPD z- scores were not statistically different between smokers and non-smokers (-0.75 ± 1.6 vs -0.51 ± 1, p = .3). HC measurements and z- scores were significantly lower in the smoking group than in the non-smoking groups (183.38 ± 14.56 vs. 189.28 ± 12.53, p = .003, 0.18 ± 1.39 multiple of median (MoM) vs. 0.56 ± 0.92, respectively, p = .023). At linear regression analysis, maternal smoking was the only independent factor associated with fetal HC z score (p = .041). In conclusion, continued smoking during pregnancy reduces fetal HC and has no effect on BPD, LV, or CM measurements at mid-gestation.IMPACT STATEMENTWhat is already known on this subject? Smoking during pregnancy is one of the most common environmental factors affecting fetal and neonatal growth and well-being. Despite the well-known effects of smoking on somatic growth, current studies have shown that it selectively affects some parts of the fetal brain, even in appropriately growing fetuses.What do the results of this study add? Continued smoking during pregnancy reduces fetal HC and has no effect on BPD, LV or CM measurements at mid-gestation. Since smoking is well known for its early and late childhood behavioral and neurological consequences, smaller mid-trimester fetal HC measurements should bring maternal smoking to mind as one of the potentially reversible causes.What are the implications of these findings for clinical practice and/or further research? The harmful effects of smoking start before the third trimester and antenatal counseling should be started early in the gestation. Every effort should be made to quit smoking before or early in pregnancy.
- PublicationUnknownIncidence and outcomes of eclampsia: a single-center 30-year study(2019-04-01T00:00:00Z) Uludag, Semih Zeki; Karasu, AYŞE FİLİZ; KÜTÜK, MEHMET SERDAR; TAKMAZ, TAHA; GÖKMEN KARASU, AYŞE FİLİZ; KÜTÜK, MEHMET SERDAR; TAKMAZ, TAHAObjective: We aimed to determine the incidence of eclampsia at Erciyes University Hospital which is a tertiary referral center situated at central Anatolia. Additionally, we investigated eclampsia-associated maternal and perinatal outcomes for the 30-year study period. Methods: A retrospective review was performed for all women who were diagnosed with eclampsia and admitted to the Erciyes University Medical School, Department of Obstetrics and Gynecology from January 1985 to December 2015. Improvement in management gained over time was determined by comparing the results of the years 2005-2015 with data which were already published from years 1985-1999 and 2000-2004. Results: Eclampsia prevalence was 289/46,928 (% 0.61). Maternal age at the time of diagnosis did not differ statistically; however, gestational age at diagnosis and birth weight decreased significantly throughout the years (p < 0.005). The perinatal mortality rate showed a slight decrease throughout the years (p = 0.238). Maternal mortality rate also decreased throughout the years; it was 1.7% in 2005-2009 and 0 % in 2010-2015 (p = 0.246). Conclusion: The prevalence of eclampsia cases has decreased over the years. Maternal mortality attributed to eclampsia has also declined. The early diagnosis and treatment of eclampsia have resulted in the increase of premature deliveries. The perinatal mortality rate showed a slight decrease throughout the years (p = 0.238); however, it is not at a desirable rate compared to developed countries.
