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.Publication Prenatal 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.Publication Excision of subcutaneous endometriosis lesions in obese patients by marking them with methylene blue with ultrasound guidance: a novel technique(2023-01-01) ÇETİN Ç.; KÜTÜK M.

True knots are mostly asymptomatic; however, cord related accidents may be encountered.Publication Effect of maternal smoking during pregnancy on fetal circulation and growth(2023-06-25) Kütük M. S.; Bakar R. Z.; Toluk Ö.; Çetin Ç.; Yozgat C. Y.; Doygun Ö.; KÜTÜK, MEHMET SERDAR; BAKAR, RABIA ZEHRA; TOLUK, ÖZLEM; ÇETİN, ÇAĞLARObjective To understand the pathogenic mechanism of smoking on abnormal fetal growth by assessing the umbilical, and middle cerebral pulsatility index (MCA- PI, and UmA-PI, respectively) cerebroplacental ratio (CPR) and middle MCA peak systolic velocity (MCA-Vmax). Methods A hundred and eighty-one pregnant women were included in the study, 118 of whom were ever smoker and 62 were smoker. Smoking status of the cases were based on the participants statements and confirmed with breath CO test. Patients were undergo Doppler examination according to thecurrent guidelines at 24, 28, 32 and 36 weeks and the results were expressed as z- scores. UmA- PI, MCA-PI, CPR (MCI-PI/UmA-PI), MCA- Vmax were compared between control and smoking groups. As a subgroup analysis, effect of heavy smoking (>10/day) on fetal growth and Doppler indexes were also compared. Results Body mass index (BMI), gravida, rate of gestational hypertension and neonatal intensive care admission is significantly higher in smoking group. Birthweight and gestational age at birth was significantly higher in control group [3355 (1960.0-4660.0) vs 3162.5(550.0-4190.0), p=0.003, and274.0(250.0-294.0) vs. 271(175.0-288.0), p=0.015, respectively]. When controlled for confounding factors, no significant difference was detectedbetween smokers and control groups with regard to UmA-PI, MCA-PI, MCA- V Max and CPR, at 24 , 28 , 32 , 36 weeks. EFW at all gestational ages were significantly lower in smoker group (p=0.033). At subgroup analysis, no significant difference was detected between control and heavy smokers in terms of EFW and all Doppler parameters. Conclusion Smoking during pregnancy is associated decreased fetal growth and increased abnormal neonatal outcome. However, it has no demonstrable effect on any of the Doppler indexes and velocities at any given gestational ages. Abnormal effect of smoking on fetal growth seems not to operate throughimpaired uteroplacental circulationPublication Evaluation 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.Publication The Effects of Maternal Smoking on Thyroid Function: Findings from Routine First-Trimester Sonographic Anomaly Screening(2023-01-01) BAKAR R. Z.; ÇETİN Ç.; Yozgat C. Y.; KÜTÜK M. S.; BAKAR, RABIA ZEHRA; ÇETİN, ÇAĞLAR; KÜTÜK, MEHMET SERDARAim This study aimed to assess the effect of tobacco exposure on maternal thyroid function and investigate its relationship to subclinical hypothyroidism in pregnant women during the first trimester. Subjects and Method A comparison of maternal thyroid function was made on 45 smokers, who composed the study group, and 72 non-smokers, pregnant women, who constituted the control group. After determining smokers by questionnaire, carbon monoxide (CO) levels in the expiratory air of the participants in both groups were measured and recorded, and the smokers\" exposure was objectively confirmed. Results Smoking and non-smoking pregnant women were similar regarding body mass index (BMI). While the TSH and fT4 levels were respectively 1.48 mlU/L and 11.43 pmol/L in pregnant women who smoked, that ratio changed to 1.72 mlU/L and 11.17 pmol/L in the non-smokers\" group. But the differences between the groups were not statistically significant (p=0.239, p=0.179). Even though the rate of subclinical hypothyroidism was 8.9% in the smoking group, it was approximately 19.4% in the non-smoker group; the difference was not statistically significant (p=0.187). Conclusion This study proved that there is no statistically significant difference between maternal serum TSH and fT4 levels and the rate of subclinical hypothyroidism in smokers during pregnancy in the first trimester.Publication Kayseri bölgesinde 1985-2015 yılları arasında eklampsi insidansınındeğerlendirilmesi(2018-10-30T00:00:00Z) ULUDAĞ, SEMİH ZEKİ; GÖKMEN KARASU, AYŞE FİLİZ; KÜTÜK, MEHMET SERDAR; GÖKMEN KARASU, AYŞE FİLİZ; KÜTÜK, MEHMET SERDARPublication Prenatal Detection and Postnatal Outcome of Persistent Left Superior Vena Cava and Agenesis of Ductus Venosus Associated with Postnatal Bovine Aortic Arch(2023-12-20) Elbistanli C.; YOZGAT Y.; Dogan M. S.; Yozgat C. Y.; KÜTÜK M. S.; KÜTÜK, MEHMET SERDARBackground Isolated agenesis of ductus venosus (ADV) is usually a benign condition, but it may be associated with cardiovascular defects, hydrops, growth restriction, and chromosomal abnormalities. Additionally, persistent left superior vena cava (PLSVC) and bovine aortic arch are relatively common fetal anomalies. To the author\"s knowledge, this is the first report of prenatal detection of DV agenesis and PLSVC associated with the postnatal bovine aortic arch with a hypoplastic transverse aortic arch.Case A 25-year-old, G2P1 woman was referred to our department at 31 weeks due to fetal growth restriction and short femur. On fetal echocardiography, DV could not be viewed via two-dimensional (2D) and Doppler ultrasound (US) imaging; there was also evidence of the co-occurrence of PLSVC and an aortic arch anomaly. We revealed the intrahepatic continuation of the umbilical vein. A weekly follow-up program was scheduled for the patient and the rest of the pregnancy was uneventful. Postnatal, thorax computer tomography and transthoracic echocardiography (TTE) demonstrated PLSVC and bovine aortic arch associated with hypoplastic transverse aortic arch. Routine echocardiographic examinations revealed that the blood flow of the aortic arch had increased gradually, and the male infant\"s aortic arch had significantly widened and reached the normal range until the baby was discharged from the hospital.Conclusion DV agenesis and PLSVC are usually benign conditions but underlying serious heart diseases may accompany them. Therefore, in situations like ours, a prenatal aortic arch evaluation is of capital importance. Postnatal hemodynamic changes should be taken into consideration in the management of these cases. This is the first example in the literature that these abnormalities co-existed in one case.
