Öğe Comparison of serum levels of cell adhesion molecules (E-selectin, P-selectin, ICAM-1, VCAM-1, LRG-1) in placental invasion and adhesion anomalies with patients with vaginal delivery and former cesarean(Springer Heidelberg, 2023) Ersuz, Rutkay; Karapinar, Oya Soylu; Dogan, SerdarObjectiveIt is aimed to be a technique that can be used for diagnosis and to prevent maternal deaths in cases where the serum levels of cell adhesion molecules are different in patients with abnormal placentation compared to healthy pregnant women.Materials and methodsPatients between March 2020 and September 2021 were included in the study. While 56 patients, out of 153 cases formed the placental adhesion and/or localization anomaly group, 55 cases without placental adhesion anomaly (placental invasion anomaly and/or previa pathology) constituted the cesarean section group and 42 cases constituted the vaginal birth control group. Demographic characteristics and histories of 153 patients were questioned. I-CAM-1, V-CAM-1, E-Selectin, P-Selectin, LRG-1 levels were studied. The parameters measured by the ELISA method were studied in the Thermo Fisher Scientific Multiscan Go (Finland) device at the Hatay Mustafa Kemal University Medical Faculty Medical Biochemistry USA ELISA Laboratory. Wholehouse and One Way Anova analysis methods were used to compare the results.ResultsThere were significant differences in E-Selectin, P-Selectin, ICAM-1 and LRG-1 values between the groups (p < 0.05). There was a significant difference between the vaginal birth (VB) and previa/percreata (PP) groups in terms of E-Selectin (p = 0.038). In terms of P-Selectin, there was a significant difference between the C/S and previa/percreata (PP) groups (p < 001). P-Selectin was higher in the previa/percreata (PP) group. There was a significant difference between the Vaginally birth (VB), C/S group (p = 0.041) and the vaginal birth (VB), previa/percreata (PP) group (p = 0.013) in terms of ICAM-1, but there was no significant difference between the C/S and previa/percreata (PP) groups. In terms of LRG-1, there was a significant difference between all 3 groups (p < 0.05).DiscussionA recent study investigated the potential modulatory effects of trans-resveratrol (RSV), arginase and endothelial dysfunction biomarkers in patients with PE. Another reflection of endothelial dysfunction in PE is increased endothelial activation biomarkers such as intercellular adhesion molecule-1 (ICAM-1), von Willebrand factor (vWF), and Caspase-3 (CASP-3). The study, regarding vWF expression, the preeclampsia (PE) group showed higher levels compared to endothelial cells incubated with healty pregnant (HP) plasma [Bueno-Pereira et al 2022 Antioxidants 2111]. From this and similar studies, the hypothesis that the role of cell adhesion molecules in endothelial damage may be the underlying cause of invasion and location anomalies emerges. This hypothesis is the starting point of our study.ConclusionsIn our study, all adhesion molecules except V-CAM-1 were found to be significantly higher in the previa/percreata (PP) group. E-Selectin and LRG-1 adhesion molecules were found to be significantly higher even in C/S patients compared to normal delivery. As a result; these adhesion molecules can be studied as a marker in previa/percreata (PP) patients.Öğe Does menopause effect nasal mucociliary clearance time?(Springer, 2015) Ozler, Gul Soylu; Akbay, Ercan; Akkoca, Ayse Neslin; Karapinar, Oya Soylu; Simsek, Gokce OzelThe aim of this study was to investigate the effect of menopause on nasal mucociliary clearance time by comparing the results of premenopausal and postmenopausal women. A total of 60 women met the criteria and were divided into two groups: premenopausal women (n = 30) and postmenopausal women (n = 30). Nasal mucociliary clearance time of these women was measured and compared. Moreover, the correlation between nasal mucociliary clearance time and menopause duration in postmenopausal women was evaluated. Statistical analysis was performed using the SPSS (Statistical Package for the Social Sciences) 13.0 Evaluation for Windows. Normal distribution of continuous variables was tested with Kolmogorov-Smirnov test. Chi square test was used for comparisons between categorical variables. Kruskal-Wallis test and Mann-Whitney U tests were used for continuous variables when comparing the groups. The statistically significant level was accepted as p value < 0.05. The mean nasal mucociliary clearance time in premenopausal and postmenopausal women was 11.43 +/- A 2.81 (7-16) and 16.76 +/- A 2.73 (12-22), respectively. The mean nasal mucociliary clearance time in postmenopausal women was significantly longer than in premenopausal women (p < 0.0001). Also, there was positive correlation between menopause duration and nasal mucociliary clearance time in postmenopausal women (r = 0.833, p < 0.0001). The clinicians must keep in mind that nasal mucociliary clearance time in postmenopausal women is prolonged and must follow up women in postmenopausal period more closely for respiratory tract diseases, sinonasal and middle ear infections.Öğe Does the presence of anhydramnios affect the duration of medical abortion?(Via Medica, 2016) Karapinar, Oya Soylu; Gungoren, Arif; Dolapcioglu, Kenan; Silfeler, Dilek Benk; Kurt, Raziye Keskin; Sahin, Hanifi; Hakverdi, Ali UlviObjectives: The aim of the study was to determine whether anhydramnios affected the duration of medical abortion in cases with various indications as compared to cases with normal amniotic fluid volume. Material and methods: Patients who were admitted to our clinic because of medical abortion between January 2010-December 2013 were included in this retrospective study. A total of 32 pregnant women with anhydramnios (study group) and 67 pregnant women with normal amniotic fluid volume but with fetal abnormality (control group) were included in the study. Patient age, gravidity, parity, gestational age, previous delivery route, and duration of the abortion were recorded. Results: Mean duration of the abortion in the study group was 71.93 +/- 47.51 h as compared to 79.08 +/- 52.62 h in the control group. There were no statistically significant differences between the two groups in terms of duration of the abortion (p = 0.516). Also, we found no statistically significant differences in duration of the abortion with regard to previous delivery route (p = 0.220). Conclusions: There were no statistically significant differences between the study group and controls in terms of duration of the abortion. In addition, neither parity nor previous delivery route affected the duration of the abortion.Öğe Effect of alpha-lipoic acid on endometrial implants in an experimental rat model(Wiley, 2017) Pinar, Neslihan; Karapinar, Oya Soylu; OEzcan, Oguzhan; Ozgur, Tumay; Bayraktar, SuphiTo investigate the antioxidant and anti-inflammatory effects of alpha-lipoic acid (ALA) in the treatment of endometriosis in an experimental rat model by evaluating biochemical and histopathologic parameters. Experimental endometriosis was induced by the peritoneal implantation of autologous endometrial tissue. The rats were randomly divided into two groups with eight rats each. Group I was intraperitoneally administered ALA 100 mg/kg/day for 14 days. Group II was intraperitoneally administered saline solution at the same dosage and over the same period. Endometrial implant volume was measured in both groups both pre- and post-treatment. Tumor necrosis factor alpha (TNF-) was measured in peritoneal fluid. Total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) were assessed in serum. The implants were histopathologically evaluated. In the ALA group, the serum TOS and OSI levels, the endometrial implant volumes, the TNF- levels in serum and peritoneal fluid, and the histopathologic scores were significantly lower compared to the control group (P < 0.05). Alpha-lipoic acid may have a therapeutic potential in the treatment of endometriosis due to its antioxidant and anti-inflammatory effects.Öğe The effect of dexpanthenol on experimentally induced ovarian ischaemia/reperfusion injury: a biochemical and histopathological evaluation(Springer Heidelberg, 2017) Karapinar, Oya Soylu; Pinar, Neslihan; Ozcan, Oguzhan; Dogan, Esin Atik; Bayraktar, Suphi; Sahin, Hanifi; Dolapcioglu, KenanThe aim of this study was to evaluate the effect of two different doses of dexpanthenol (Dxp) onexperimentally induced ovarian ischaemia/reperfusion (I/R) injury ina rat model. Forty female rats were randomly divided into fivegroups: Group 1: sham operation; Group 2: 3-h ischaemia; Groups 3: 3-h ischaemia, 3-h reperfusion (I/R); Group 4: I/R + 300 mg/kg Dxp intraperitoneally (i.p) Group 5: I /R + 500 mg/kg Dxpi.p. Total anti-oxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), tissue malondialdehyde (MDA) and activities of glutathione peroxidase and catalase were calculated. Ovarian tissue damage was assessed using a histopathological scoring system. The TOS and OSI values were significantly lower in Group 5, as compared to Groups 2 and 3 (p < 0.05). The MDA levels in Group 1 and Group 5 were significantly lower than those in Group 3 (p < 0.05). CAT and GSH-Px activity was higher in Group 5 than in Group 2 and Group 3 (p = 0.00). Tissue damage scores were elevated in all the groups compared with sham group, but the treatment with the different doses of Dxp before reperfusion ameliorated the tissue damage scores. The results showed that Dxp reduced ovarian I/R injury.Öğe The effect of molar pregnancies on platelet parameters(Taylor & Francis Inc, 2016) Karapinar, Oya Soylu; Silfeler, Dilek Benk; Dolapcioglu, Kenan; Kurt, Raziye Keskin; Beyazit, AhmetThe aim of this study was to compare platelet parameters between abortus groups with gestational trophoblastic disease (GTD) (molar pregnancy, invasive mole, choriocarcinoma, etc) and without disease according to pathological result. The study population consisted of patients with GTD (n=53) and aborted patients without disease as a control group (n=53) who were seen in our clinic between January 2010 and December 2013. In this retrospective study, age, gravidity, levels of haemoglobin, white blood cell count, platelets, platelet parameters (mean platelet volume (MPV), platelet distrubition width (PDW), platelet crit (PCT), which shows platelet functions were recorded. The pathological diagnosis of GTD was recorded. The mean platelet count, MPV, PDW and PCT levels were similar between the groups. There is no statistically significiant difference between types of GTN in these parameters according to pathological diagnosis. According to our study results, platelet count and levels of MPV, PDW ve PCT in GTD patients were similar to aborted patients without disease.Öğe The effectiveness of the double B-lynch suture as a modification in the treatment of intractable postpartum haemorrhage(Taylor & Francis Inc, 2018) Sahin, Hanifi; Karapinar, Oya Soylu; Sahin, Eda Adeviye; Dolapcioglu, Kenan; Baloglu, AliA broader range of more effective compression techniques are needed in the patients who have an intractable postpartum haemorrhage due to uterine atony despite medical treatment and B-Lynch sutures. The aim of this study was to report the outcome of a series of patients with haemorrhage who were managed by double B-Lynch suture. Fourteen patients who were treated in a tertiary hospital between July 2010 and February 2015 were included in the study. The intractable haemorrhage rate was 0.35% over 5 years (14/4000 births). Bleeding was controlled in all the patients with a double B-Lynch suture. The mean age of the patients was 24 +/- 3.4years. The mean estimated blood loss was 1696 +/- 272.075mL, and the mean transfusion rate was 4.2 +/- 2.5 units. Pregnancy was observed in five patients at follow up. The double B-Lynch suture seems to be an effective and reliable solution to an intractable postpartum haemorrhage resulting from uterine atony and has no unfavourable impacts on fertility. It should be considered before the use of any aggressive surgical techniques such as a hypogastric artery ligation or a hysterectomy. This the first study to investigate the effectiveness of the double B-Lynch suture, and we showed that the hysterectomy and/or hypogastric artery ligation rate can be decreased by adding a second B-Lynch suture in cases where the medical treatment or a single B-Lynch has failed. IMPACT STATEMENT What is already known on the subject? Uterine atony is the most common cause of a primary postpartum haemorrhage. When a simple massage of the uterus and medication failed to manage this condition, various surgical solutions have been sought, including uterine compression sutures, uterine artery ligation, devascularisation of the uterus, internal iliac artery ligation and, ultimately, a hysterectomy. The B-Lynch suturing technique is particularly useful because of its simplicity of application, life-saving potential, relative safety and capacity for preserving the uterus and subsequent fertility. To-date, this suturing technique, when applied correctly, has been successful with no problems and no apparent complications. However in the cases of when it falls, usually a hysterectomy or a hipogastric artery ligation is preferred. What does this study add? A double B-Lynch suture seems to be an effective and reliable method in an intractable postpartum haemorrhage due to a uterine atony and has no unfavourable impact on fertility'. What are the implications of these findings for clinical practice? The double B-Lynch suture seems to be an effective, reliable and technically easy method. With this aspect, it might be considered before any aggressive surgical techniques, such as a hypogastric artery ligation and hysterectomy in selected cases.Öğe Evaluation of vaginal agenesis treated with the modified McIndoe technique: A retrospective study(Galenos Yayincilik, 2016) Karapinar, Oya Soylu; Ozkan, Mustafa; Okyay, Ayse Guler; Sahin, Hanifi; Dolapcioglu, Kenan SerdarObjective: Retrospective analysis of cases that have undergone neovagina operation because of congenital vaginal agenesis was objected. Material and Methods: Seven cases applying with the complaints of primary amenorrhea or inability to have sexual intercourse were in the study. The cases were diagnosed with congenital vaginal agenesis and operated at Mustafa Kemal University Training and Research Hospital between 2011 and 2014. Vaginoplasty by the modified McIndoe method was performed in all cases. The main complaint, chromosomal analysis, duration of operation, preoperative and postoperative vaginal length, complications, postoperative treatment, and satisfaction from the sexual intercourse were all evaluated. Results: Average age of our patients was 28.14 +/- 8.61 (19-39) years. One patient was 46XX-45X0 mosaic Turner syndrome), 1 patient was 46XY (testicular feminization), and other 5 patients were 46XX. The average duration of operation was 2.7 +/- 0.56 (2-3.5 h). Postoperative infection was observed in 1 patient. In this infected patient, graft failure occurred and debridement was performed in reoperation. No early complications were seen in the others. Preoperative and postoperative average vaginal lengths were 1.85 +/- 0.62 (1-3 cm) and 8.71 +/- 1.11 (7-10 cm), respectively. Dyspareunia occurred in 2 cases that were not able to use dilatator regularly: 1 because of cancelation of marriage and the other because of postoperative infection; regular sexual life was achieved in remaining 5 (71%) cases. Conclusion: Although there is no consensus about the ideal method of making a functioning vagina among different specialties. The modified McIndoe technique is the most applied method by gynecologists and simple, minimally invasive and with low morbidity.Öğe Increased Density of Demodex folliculorum Mites in Pregnancies with Gestational Diabetes(Karger, 2014) Kurt, Raziye Keskin; Kaya, Ozlem Aycan; Karateke, Atilla; Silfeler, Dilek Benk; Karapinar, Oya Soylu; Akkoca, Ayse Neslin; Hakverdi, Ali UlviObjective: To investigate the presence of Demodex in patients with gestational diabetes and the impact of glucose regulation on Demodex density in gestational diabetes. Subjects and Methods: The study population consisted of 33 patients with gestational diabetes and 30 pregnant women without gestational diabetes (control group). The age, parity, gestational age, and BMI of the study group were recorded and the patients were divided into 2 groups, i. e. those with regulated and unregulated glucose levels, according to their postprandial 1st-and 2nd-hour glucose values. A standardized skin surface biopsy method was used to determine if patients had Demodex folliculorum infestation (> 5 mites/cm 2 of skin). Results: Patients with gestational diabetes had a statistically significantly higher Demodex density compared to the control group (24.2 vs. 3.3%; p < 0.001). Furthermore, a significantly higher proportion of gestational diabetes patients with unregulated glucose levels had a higher Demodex density compared to those in the regulated subgroup (6/19 vs. 2/14; p = 0.001). Conclusion: Our study revealed that the Demodex density was increased in gestational diabetes patients. Further, poor glucose regulation could be the mechanism responsible for the increased Demodex density in gestational diabetes patients with unregulated glucose levels compared to those with regulated glucose levels.

Karger AG, BaselÖğe Investigation of the Retinal and Optic Disc Microvascularization in Polycystic Ovary Syndrome: An Optical Coherence Tomography Angiography Study(Taylor & Francis Inc, 2023) Elbeyli, Ahmet; Kurtul, Bengi Ece; Karapinar, Oya SoyluPurpose To investigate retinal and optic disc microvascular alterations using optical coherence tomography angiography (OCTA) in women with polycystic ovary syndrome (PCOS). Methods Forty-six eyes of 23 patients with PCOS (PCOS group), and 50 eyes of 25 sex and age-matched healthy controls (control group) were included in this cross-sectional study. Foveal retinal thickness, peripapillary retinal nerve fiber layer (RNFL) thickness, vessel density in different sections of the retina and optic disc were analyzed by OCTA. Results The superficial parafoveal vessel densities were significantly lower in PCOS group compared to the control group (53.7 +/- 4.0%, and 55.4 +/- 2.7%, respectively, p = .02). The deep retinal vessel densities, foveal retinal thicknesses and RNFL thicknesses, whole image of optic disc radial peripapillary capillary densities, foveal avascular zone and flow areas were similar between the groups (p > .05 for all). Conclusion OCTA analysis indicates that patients with PCOS tend to have lower superficial parafoveal vessel densities.Öğe Postpartum Ovarian Vein Thrombosis Due to COVID-19 in Pregnancy: A Case Report(Springernature, 2023) Beyazit, Ahmet; Karapinar, Oya Soylu; Dolapcioglu, Kenan Serdar; Beyazit, SelenOvarian vein thrombosis is a clinic condition that is generally seen in the postpartum period and can mimic acute appendicitis with acute abdomen. The incidence of occurrence has increased further in cases predisposing to thrombosis. Coronavirus disease 2019 (COVID-19) during pregnancy causes increased thromboembolic events. Here we examined a case of ovarian vein thrombosis after stopping enoxoparin in a postpartum patient who had COVID-19 during pregnancy.Öğe Protective effect of alpha-lipoic acid in methotrexate-induced ovarian oxidative injury and decreased ovarian reserve in rats(Taylor & Francis Ltd, 2017) Karapinar, Oya Soylu; Pinar, Neslihan; Ozcan, Oguzhan; Ozgur, Tumay; Dolapcioglu, KenanTo determine whether the possible oxidative effect of methotrexate (Mtx) on ovary and to evaluate the effectiveness of alpha lipoic acid (ALA), which may be useful in many oxidative stress models.Thirty-two female Wistar-albino rats were randomly divided into four groups; control group, alpha lipoic acid group (ALA 100mg/kg, 10days), multiple dose Mtx group (Mtx 1mg/kg 1, 3, 5, 7days) and Mtx and ALA group (Mtx 1mg/kg 1, 3, 5, 7days and ALA 100mg/kg, 10days). Serum total antioxidant status (TAS), total oxidant status (TOS) and oxidative stress index (OSI), tumor necrosis factor-alpha (TNF-), tissue malondialdehyde (MDA) and activities of glutathione peroxidase (GSH-Px) and catalase (CAT) and anti-Mullerian hormone (AMH) and total ovarian follicle count were evaluated.Mtx administration caused a significant decrease in TAS, a significant increase in TOS and OSI, a significant increase in MDA levels and a decrease in GSH-Px and CAT activity. Moreover the proinflammatory cytokine (TNF-) was increased in the Mtx group. And AMH values and total follicle count were significantly decreased in Mtx group. However, ALA treatment reversed biochemical results and AMH levels and total follicle count.Alpha lipoic acid ameliorates methotrexate induced oxidative damage of ovarian in rats.Öğe Protective effects of tempol in an experimental ovarian ischemia-reperfusion injury model in female Wistar albino rats(Canadian Science Publishing, 2017) Pinar, Neslihan; Karapinar, Oya Soylu; Ozcan, Oguzhan; Dogan, Esin Atik; Bayraktar, SuphiThe aim of this study was to investigate the antioxidant effects of tempol on ovarian ischemia-reperfusion (I/R) injury in rats. Forty female Wistar albino rats were randomly divided into 5 groups: Group I, sham; Group II, ischemia (I); Group III, I/R; Group IV, I/R + tempol 30 mg/kg i.p; Group V, I/R + tempol 50 mg/kg i.p. Oxidative stress index (OSI) was significantly higher in the ischemia group and the I/R group than in the sham group. Catalase levels were significantly lower in the I/R group than in the I/R + tempol 30 mg/kg i.p. and the I/R + tempol 50 mg/kg i.p. groups. Glutathione peroxidase levels were lower in the I/R group than in the I/R + tempol 30 mg/kg i.p. and the I/R + tempol 50 mg/kg i.p. groups. MDA levels were significantly lower in the I/R + tempol 30 mg/kg i.p. group and the I/R + tempol 50 mg/kg i.p. group than in the I/R group. The levels of the histopathological parameters were significantly decreased in the I/R + tempol 50 mg/kg i.p. group compared with the I/R group. Tempol can be used for reducing ovarian I/R injury.Öğe The Protective Role of Dexpanthenol on the Endometrial Implants in an Experimentally Induced Rat Endometriosis Model(Springer Heidelberg, 2017) Karapinar, Oya Soylu; Pinar, Neslihan; Ozgur, Tumay; Ozcan, Oguzhan; Bayraktar, H. Suphi; Kurt, Raziye Keskin; Nural, OrhanObjective: Dexpanthenol (Dxp), antioxidant and anti-inflammatory agent, plays an important role in the repair systems against oxidative stress and inflammatory response. The objective of this study is to determine the effect of Dxp on experimental endometriosis model. Study Design: A prospective experimental study was conducted in Experimental Animal Laboratory of Mustafa Kemal University, Hatay. Twenty nonpregnant female Wistar albino rats, in which experimental model of endometriosis was surgically induced, were randomly divided into 2 groups. Group 1 was administered 500 mg/kg/d Dxp intraperitoneally for 14 days, and group 2 was given the same amount of saline solution. After 2 weeks of medication, the rats were killed and implant volumes, histopathologic scores; and levels of serum total antioxidant status, total oxidant status (TOS), and oxidative stress index (OSI) were evaluated. Plasma and peritoneal fluid levels of tumor necrosis factor (TNF-) were analyzed. Results: The endometriotic implant volumes, histopathologic scores, and serum TOS and OSI values were significantly decreased (P < .05) in the Dxp group compared to the control group. Plasma and peritoneal fluid TNF- levels were significantly decreased (P < .05) in the Dxp group compared to the control group. Conclusion: Dexpanthenol has free radical scavenger effects, and antioxidant properties has significantly regressed endometriotic implant volumes, histopathologic scores, and serum TOS and OSI values. Serum and peritoneal fluid TNF- levels were significantly decreased in the Dxp group. So Dxp decreased oxidative stress.Öğe Theranekron for treatment of endometriosis in a rat model compared with medroxyprogesterone acetate and leuprolide acetate(Elsevier, 2013) Dolapcioglu, Kenan; Dogruer, Gokhan; Ozsoy, Sule; Ergun, Yasar; Ciftci, Sinasi; Karapinar, Oya Soylu; Aslan, ErdoganObjectives: The aim of this study was to compare the effects of theranekron, medroxyprogesterone acetate (MPA), and leuprolide acetate (LA) on surgically induced endometriosis in a rat model. Study design: Endometriosis was surgically induced in forty female rats during estrus. After 3 weeks, a second operation was performed and the rats were randomized using a randomization table into theranekron, MPA, LA, and control groups. These treatments were continued for 3 weeks. A third operation was performed to evaluate treatment results. Then, the experimental treatments were halted and estrogen was initiated again to maintain estrus. After three additional weeks; i.e. after 9 weeks, the recurrence rate of endometrial foci was evaluated in a fourth operation and the rats were sacrificed. The volume of endometriotic foci and histopathology scores before and after treatment were compared. Results: The respective mean volumes of the endometriotic foci after 3, 6, and 9 weeks were 86.4 +/- 21.2, 16.4 +/- 8.2, and 20.1 +/- 9.6 mm(3) in the theranekron group, 78.3 +/- 20.4, 42.6 +/- 13.5, and 66.7 +/- 16.2 mm(3) in the MPA group, and 91.8 +/- 30.2, 34.4 +/- 11.4, and 72.4 +/- 21.9 mm(3) in the LA group. The respective mean histopathology scores were 2.4 +/- 0.6, 1.8 +/- 0.6, and 1.6 +/- 0.6 in the theranekron group, 2.5 +/- 0.8, 2.0 +/- 1.1, and 2.7 +/- 1.0 in the MPA group, and 2.3 +/- 0.5, 2.1 +/- 1.2, 2.4 +/- 0.8 in the LA group. After 9 weeks, the mean volume of endometriotic foci and histopathology scores were significantly lower in the theranekron group. Conclusions: Theranekron caused more evident regression of endometriotic foci than MPA or LA in a rat model. After stopping the theranekron treatment, the recurrence rate was also lower than that of the other groups. (C) 2013 Elsevier Ireland Ltd.

The purpose of this study was to evaluate YKL-40 tissue expression in extravillous trophoblast invasion and its possible implication in placenta creta. Methods: A total of 35 placenta creta cases and six control cases were included in the study, of which eight cases were placenta accreta, 12 were increta and 15 were percreta. Histological YKL-40 staining was scored in tissue as weak (1), medium (2) and strong (3). Results: YKL-40 immunoreactivity intensity in the percreta group was significantly higher compared to the increta and accreta groups (2.47 +/- 0.74, 1.33 +/- 0.49 and 1.37 +/- 0.52, respectively; P = 0.000). YKL-40 immunoreactivity intensity was positively correlated with creta (r = 0.6; P = 0.000), depth of invasion (r = 0.49; P = 0.003) and depth of invasion to full thickness ratio (r = 0.58; P = 0.000). Conclusion: This study demonstrated that YKL-40 is strongly expressed in placenta percreta and is correlated with extravillous trophoblast invasion. These findings may be informative for understanding the pathophysiology of placenta creta.
