The efficacy of onion extract in the management of subsequent abdominal hypertrophic scar formation.

J Wound Care 2020 Oct;29(10):612-616

Süleymaniye Maternity Research and Training Hospital, Obstetrics and Gynecology Clinic, Zeytinburnu, Istanbul, Turkey.

Objective: Development of postoperative scars is often a problem. This study aimed to evaluate the efficacy of gel containing extract, allantoin and heparin (Contractubex, Merz Pharmaceuticals GmbH, Frankfurt, Germany) in reducing scarring after a caesarean section by comparing it with a control group, and also intra-individually, using the Vancouver Scar Scale (VSS).

Method: A total of 120 patients who underwent a second elective caesarean delivery and who presented with hypertrophic scar development after their first caesarean section were included in the study. A scar revision was performed for all patients during the second caesarean operation. Patients in the study group (n=60) were advised to apply the topical scar gel postoperatively for a period of 6 months. The control group (n=60) received no treatment.

Results: Significant reductions were observed in the vascularity, pigmentation and height subgroups of the VSS for those in the group who continued the treatment to 24 weeks. An intra-individual analysis showed that the gel effectively reduced scarring after the second caesarean section.

Conclusion: The prophylactic use of the gel to reduce scar development offers better results for vascularity, pigmentation and height subscales of the VSS after surgical removal of the primary caesarean scar during the second caesarean section. The results were better both intra-individually, and also in comparison with the control group and support the use of a gel containing extract, allantoin and heparin to reduce scarring after a caesarean section.

Does bilateral uterine artery ligation have negative effects on ovarian reserve markers and ovarian artery blood flow in women with postpartum hemorrhage?

Clin Exp Reprod Med 2019 Mar 1;46(1):30-35. Epub 2019 Mar 1.

Department of Obstetrics and Gynecology, Suleymaniye Maternity, Research and Training Hospital, University of Health Sciences, Istanbul, Turkey.

Objective: Bilateral uterine artery ligation (UAL) is a fertility-preserving procedure used in women experiencing postpartum hemorrhage (PPH). However, the long-term effects of this procedure on ovarian function remain unclear. The aim of this study was to investigate whether bilateral UAL compromised ovarian reserve and ovarian blood supply.

Methods: This prospective study included 49 women aged between 21 and 36 years who had undergone a cesarean section for obstetric indications. Of these, 25 underwent uterine bilateral UAL to control intractable atonic PPH. The control group consisted of 24 women who had not undergone bilateral UAL. Standard clinical parameters, the results of color Doppler screening, and ovarian reserve markers were assessed in all participants at 6 months after surgery. The clinical parameters included age, parity, cycle history, body mass index, and previous medication and/or surgery. Color Doppler screening findings included the pulsatility index (PI) and resistance index (RI) for both the uterine and ovarian arteries. The ovarian reserve markers included day 3 follicle-stimulating hormone (FSH) levels, antral follicle count, and anti-Müllerian hormone (AMH) levels.

Results: There were no significant differences in the ovarian reserve markers of day 3 FSH levels, antral follicle count, and AMH levels between the study and control groups (p>0.05 for all). In addition, no significant differences were observed in the PI and RI indices of the uterine and ovarian arteries (p>0.05 for all).

Conclusion: In this study, we showed that bilateral UAL had no negative effects on ovarian reserve or ovarian blood supply, so this treatment should be used as a fertility preservation technique to avoid hysterectomy in patients experiencing PPH.

Effect of Betamethasone on Fetal Pulmonary and Umbilical Artery Doppler Velocimetry and Relationship With Respiratory Distress Syndrome Development.

J Ultrasound Med 2017 Dec 19;36(12):2441-2445. Epub 2017 Jun 19.

Gynecology and Obstetrics Clinic, Süleymaniye Maternity Research and Education Hospital, Istanbul, Turkey.

Objectives: Respiratory distress syndrome (RDS) is a major cause of neonatal morbidity and mortality. It is primarily a disease of premature neonates. The aim of this study was to evaluate the impact of maternal betamethasone administration on the fetal pulmonary arteries (PAs) and umbilical arteries (UAs) and the correlation between RDS development and PA Doppler results.

Methods: Forty singleton pregnancies between 24 and 34 gestational weeks with a diagnosis of preterm birth were included prospectively. They received corticosteroids to enhance fetal lung maturity. Fetal PA and UA Doppler parameters were evaluated before and 48 to 72 hours after steroid administration. Maternal records were matched to neonatal charts, and demographic and outcome data were abstracted.

Results: There were no differences between groups for maternal age, body mass index, mode of delivery, and mean GA at steroid administration. Apgar scores at 1 and 5 minutes were significantly lower for neonates who developed RDS (P < .05). There were no statistically significant differences in PA Doppler results between fetuses who developed RDS and those who did not, and there were no significant differences in PA Doppler results before and after steroid administration for both groups. The UA pulsatility and resistive indices were significantly lower after steroid administration for the neonates who developed RDS (P < .05).

Conclusions: There were no significant differences in PA Doppler indices for fetuses with or without RDS after steroid administration.

Evaluation of Neutrophil-Lymphocyte Ratio, Platelet-Lymphocyte Ratio and Red Blood Cell Distribution Width-Platelet Ratio for Diagnosis of Premature Ovarian Insufficiency.

J Family Reprod Health 2016 Dec;10(4):211-216

Department of Obstetrics and Gynecology, Division of Reproductive Endocrinology and Infertility, Adnan Menderes University, Aydın, Turkey.

To evaluate whether systemic inflammatory markers (neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) and red blood cell distribution width (RDW) to platelet ratio (RPR)) can be used as reliable markers for the diagnosis of premature ovarian insufficiency (POI) and to determine if there is a relationship between these markers and follicle stimulating hormone (FSH), Anti-Müllerian Hormone (AMH) levels. Written and electronic medical records were reviewed using searches for diagnoses with the terms of 'premature ovarian failure', 'premature ovarian insufficiency'. Patients younger than the age of 40 were diagnosed to have premature ovarian insufficiency based on their menstrual history and sonographic examination and they were compared with healthy females. Complete blood counts, day-3 hormone profiles, AMH levels of all subjects were analyzed. NLR was statistically higher in POI group compared with controls (p < 0.05). NLR had a positive correlation between FSH (r = 0.23, p = 0.045) and a negative association with AMH (r = - 0.27, p = 0.018). The area under ROC curve for NLR in POI was 0.66, with a threshold value 1.5 and sensitivity = 75.7 % and specificity = 46.0 %. NLR can be a marker for the diagnosis of POI. There is a close relationship between NLR and ovarian reserve markers such as FSH and AMH.

Cervical Conization and the Risk of Preterm Birth: A Population-Based Multicentric Trial of Turkish Cohort.

J Clin Diagn Res 2017 Mar 1;11(3):QC21-QC24. Epub 2017 Mar 1.

Consultant, Department of Obstetrics and Gynaecology, Haseki Research and Education Hospital, Istanbul, Turkey.

Introduction: Cold Knife Conization (CKC) is one of the most effective methods for the treatment of Cervical Intraepithelial Neoplasia (CIN). Some studies showed a relation between preterm birth and the treatment of CIN; on the other hand, other studies do not show such a relationship.

Aim: The present study was conducted with the aim to investigate the pregnancy outcomes of Turkish women regarding demographic characteristics, obstetric history, removed tissue, and residual cervical length after CKC and to determine the effect of removed cervical tissue volume and height on preterm birth.

Materials And Methods: This study was a population-based, multicenter trial that was conducted on singleton pregnancies between January 2007 and December 2013. The control group comprised of 38,892 patients who gave birth during this period. On the other hand, patients who conceived after CKC during this period were invited to the hospital and included in the case group (n=20). The course of pregnancy following CKC was studied. Preterm birth rates, risk factors for preterm birth, conisation age, cervical smear and colposcopic biopsy results and the volume and height of the removed cervical tissue of those patients were evaluated.

Results: There was no statistically significant difference in preterm birth rates between the case and the control groups. None of our cases had any identified preterm birth risk factor except for one case. The average height of removed cervical tissue was 12.6±5.4 mm and the average length of the residual cervix after birth was 28.7±4.3 mm.

Conclusion: Removal of cervical tissue of 12.6±5.4 mm in height and 2.35±2.27 cm in volume will not increase the risk of preterm birth of women who do not have any other preterm birth risk factors. If there is no other preterm birth risk factors, term birth is most probably possible after conisation.

Cardiovascular risk may be increased in women with unexplained infertility.

Clin Exp Reprod Med 2017 Mar 31;44(1):28-32. Epub 2017 Mar 31.

Department of Obstetrics and Gynecology, Suleymaniye Maternity, Research, and Training Hospital, Istanbul, Turkey.

Objective: Growing evidence suggests that increased cardiovascular disease (CVD) risk is associated with female infertility caused by conditions such as polycystic ovarian disease, obesity, thyroid dysfunction, and endometriosis. The aim of this study was to evaluate whether any relationship exists between CVD and unexplained infertility.

Methods: Sixty-five women with unexplained infertility and 65 fertile controls were enrolled in the study. CVD risk markers such as low-density lipoprotein (LDL), high-density lipoprotein (HDL), total cholesterol (TC), triglycerides (TG), insulin resistance (defined by the homeostasis model assessment ratio), and high-sensitivity C-reactive protein (hs-CRP) were assessed.

Results: TG, TC, LDL, and hs-CRP levels were higher and HDL levels were lower in patients with unexplained infertility than in fertile controls (<0.05 for all). Positive associations were found between unexplained infertility and TG, TC, LDL, and hs-CRP levels, and a negative correlation was found for HDL (<0.05 for all). Multivariate logistic regression analysis showed that TG, HDL, and hs-CRP were independent variables associated with unexplained infertility.

Conclusion: Our study showed that women with unexplained infertility had an atherogenic lipid profile and elevated hs-CRP levels, suggesting a higher risk of developing CVD in the future. Further studies with larger groups are needed to investigate the nature of this link.

Is Maternal Blood Procalcitonin Level a Reliable Predictor for Early Onset Neonatal Sepsis in Preterm Premature Rupture of Membranes?

Gynecol Obstet Invest 2017 15;82(2):163-169. Epub 2016 Jun 15.

Department of Obstetrics and Gynecology, Yuzuncu Yil University, Faculty of Medicine, Van, Turkey.

Background: This study is aimed at comparing the early diagnostic accuracy of maternal blood white blood cell (WBC) count, C-reactive protein (CRP) and procalcitonin in predicting early onset neonatal sepsis (EONS) among early preterm premature rupture of membrane (PPROM) pregnancies.

Methods: A total of 57 consecutive pregnancies, complicated with PPROM, between 24 and 34 gestational weeks were recruited to the study at Suleymaniye Maternity Education and Research Hospital, Istanbul, Turkey between January 2012 and January 2013. All patients were hospitalized and followed up with expectant management. Maternal blood WBC count, CRP and procalcitonin levels were measured in the first 12 h of membrane rupture. EONS was diagnosed using clinical and laboratory findings, and obstetric and neonatal outcomes were noted.

Results: The cutoff value for maternal blood CRP was ≥9.49 mg/dl. This value predicted EONS with 77.8% sensitivity, 80.0% specificity, 77.8% positive predictive value (PPV) and 80.0% negative predictive value (NPV). The cutoff value for maternal blood procalcitonin was 0.071 ng/ml. This value predicted EONS with 85.2% sensitivity, 86.7% specificity, 85.2% PPV and 86.7% NPV.

Conclusion: Maternal blood procalcitonin levels were superior to maternal blood CRP and WBC count in predicting EONS. Consequently, the maternal blood procalcitonin level is a clinically useful, non-invasive and reliable biomarker in antenatal prediction of EONS.

Neither early nor late for becoming pregnant: Comparison of the perinatal outcomes of adolescent, reproductive age, and advanced maternal age pregnancies.

Turk J Obstet Gynecol 2015 Sep 15;12(3):151-157. Epub 2015 Sep 15.

Adana Numune Education and Research Hospital, Clinic of Obstetrics and Gynecology, Adana, Turkey.

Objective: To compare perinatal and short-term neonatal outcomes of adolescent, reproductive age, and advanced maternal age (AMA) pregnancies in a low-income region of İstanbul.

Materials And Methods: Three hundred six adolescents, 301 reproductive age, and 303 AMA pregnant women who delivered in Süleymaniye Education and Research Hospital between January 1 2007, and January 31 2015, were recruited to the study population. The clinical, obstetric and short-term neonatal outcomes of the women were analyzed retrospectively.

Results: Adolescent and AMA pregnancies were associated with severe adverse perinatal and short-term neonatal outcomes compared with reproductive-age women. Adolescent and AMA pregnancies had quite similar risks in obstetric outcomes. Adolescent pregnancies were related with severe adverse short-term neonatal outcomes when compared with advanced maternal age pregnancies.

Conclusion: Adolescent and AMA pregnancies should be defined as high-risk pregnancies. Our research indicated that healthcare providers such as obstetricians, midwives, and family physicians should be alert in these populations.

Effects of fetal cardiac anomalies on ductus venosus and aortic isthmus doppler profiles.

Arch Gynecol Obstet 2016 Feb 25;293(2):345-50. Epub 2015 Jun 25.

Balıkesir State Hospital, Balıkesir, Turkey.

Purpose: To demonstrate the blood flow profiles of fetuses with cardiac anomalies at the level of Ductus venosus (DV) and Aortic isthmus (AI) to evaluate the effects of fetal cardiac anomalies on these profiles, and how these profile changes contribute to cardiac anomaly screening studies as a marker.

Methods: DV and AI doppler studies were applied to 64 singleton pregnant women with fetal cardiac anomalies and 74 pregnant women with healthy fetuses. DV-PVIV (peak velocity index for veins) for DV and IFI (isthmic flow index) for AI were used.

Results: DV doppler studies in fetuses with cardiac anomalies and healthy fetuses did not show statistically significant difference. But the results of the AI doppler studies had statistically significant difference in the fetal cardiac anomaly group with the exception of cases with dilatation and regurgitation. When right-sided heart anomaly and the remaining cases were compared with the control groups, AI doppler results also showed lower IFI values.

Conclusions: DV doppler studies in the second or third trimester may not be suitable as a screening test for congenital heart disease, but AI doppler studies might be considered as a supporting parameter. But further studies are needed for routine clinical use.

Knowledge levels of adolescent girls about human papilloma virus and its vaccine.

Turk Pediatri Ars 2014 Jun 1;49(2):142-7. Epub 2014 Jun 1.

Department of Gynecology and Obstetrics, Süleymaniye Maternity Training and Research Hospital, İstanbul, Turkey.

Aim: The aim of our study was to evaluate the level of knowledge of the adolescent girls who presented to our clinic about human papilloma virus (HPV) infection and HPV vaccine.

Material And Methods: Five hundred and one adolescent girls aged between 13 and 18 years who presented to the gynecology outpatient clinic between March 2012 and March 2013 were asked to answer the questions of the questionnaire about HPV and HPV vaccine. The "Participant Information Form" and "HPV Information Assessment Form" were used by examination of the related literature by the investigators. The data obtained were entered into the computer using the SPSS 16.5 program and evaluated. Descriptive statistics were shown with mean, standard deviation, number and percentage values.

Results: The mean age of 501 subjects who were included into the study was 15.92 years. 390 subjects (77.8%) who were included in the study had no information about HPV. 111 subjects (22.2%) stated that they heard of HPV before or had information about HPV. The mean age of the subjects who had information about human papilloma virus was found to be 16.52 years. The mean age of 390 subjects (77.8%) who had no information about human papilloma virus was 15.75 years. It was found that only one of the subjects (0.9%) was vaccinated with HPV vaccine. When the subjects who did not wish to be vaccinated were asked for the reason, 40.9% stated that the reason was inadequate information, 26.4% stated that the reason was high cost, 16.4% stated that the reason was the fact that they did not consider themselves at risk and 16.4% stated that the reason was the fact that they were afraid of side effects.

Conclusions: In our study, it was found that the adolescent girls who constituted our study group had insufficient information about HPV and HPV vaccine. Verbal, written and visual communication tools and internet should be used intensively and efficiently for the objective of introducing HPV vaccine and teaching the precautions related with prevention of cervix cancer in terms of public health. Primarily pediatrician and gynecologists and family physicians who give service for the adolescence age group should be supported to develop appropriate attitudes and behaviors related with HPV vaccine and infection.

Gynecol Endocrinol 2014 Sep 22;30(9):653-6. Epub 2014 May 22.

Department of Obstetrics and Gynecology, Suleymaniye Maternity and Children's Teaching and Research Hospital , Istanbul , Turkey .

Background: To compare the effect of the GnRH antagonist/letrozole/gonadotropin protocol with the microdose GnRH agonist flare-up protocol in poor ovarian responders for intracytoplasmic sperm injection.

Materials And Methods: One hundred twenty-one consecutive patients suspected of having or with a history of poor ovarian response between January 2009 and June 2010, who were undergoing ICSI were enrolled. The microdose flareup (MF) protocol was used in 79 patients and the estradiol + progesterone/letrozole + gonadotropin and GnRH antagonist (EP/ALG) protocol was used in 42 patients.

Results: Age of the patients, duration of infertility, basal FSH, the total gonadotropin consumption, duration of stimulation, E2 level on the day of hCG administration, the number of embryo transferred, the fertilization rate, implantation rate, clinical pregnancy rate and the live birth rate were not statistically different (p > 0.05). Only the number of oocytes retrieved was significantly higher in the EP/LGA group (1.7 ± 0.7 versus 2.6 ± 0.6).

Conclusion: The EP/LGA protocol has no significant improvement against the microdose flare-up protocol in poor responder patients.

Significance of maternal plasma lead level in early pregnancy loss.

J Environ Sci Health A Tox Hazard Subst Environ Eng 2006 ;41(3):501-6

Semiha Sakir Maternity and Woman's Health Hospital, Istanbul, Turkey.

This study was undertaken to investigate the relation of plasma lead levels, and early pregnancy losses. The concentration of lead in the plasma was measured in 20 women with a history of pregnancy loss before the 20th gestational week, and the results were compared with 20 control patients with viable intrauterine pregnancy. The results showed a mean lead level of 18.8 microg/dL in the cases of pregnancy loss and 22.1 microg/dL in the control patients, thereby indicating that there is no significant relation between early pregnancy loss and maternal plasma lead levels.
