RESUMO

Around 70 percent of cases of Primary Ovarian Insufficiency (POI) etiology remain unexplained. The aim of our study is to contribute to the etiology and genetic background of POI. A total of 37 POI patients and 30 women in the reproductive period were included in this prospective, case-control study between August 2020 and December 2021. The women were examined for 36 genes with next-generation sequencing (NGS) panel. Gene variations were detected in 59.5 percent of the patients in the case group. FSHR p.S680N (rs6166, c.2039 G>A) and FSHR p.A307T (rs6165, c.919 G>A) gene variants, which are most frequently located in exon 10 of the FSHR gene, were detected in both groups. Although it was not found that these gene variants were significantly different between the groups, it was also found that they were significantly different in POI patients under 30 years of age and in those with a family history of POI. Variations were detected in 12 genes in POI patients. Two gene variants (FGFR1 [c.386A>C, rs765615419] and KISS1 [c.58 G>A, rs12998]) were detected in both groups, and the remaining gene variants were detected only in POI patients. No differences were detected between the groups in terms of gene variations. However, the gene variations detected only in POI patients may play a role in the etiology of POI.

RESUMO

OBJECTIVE: This study aimed to investigate the expression levels of sirtuin 2 and sirtuin 7 in the placenta accreta spectrum to reveal their role in its pathogenesis. METHODS: A total of 30 placenta accreta spectrum, 20 placenta previa, and 30 controls were experienced. The sirtuin 2 and sirtuin 7 expression levels in the placentas of these groups were determined by Western blot. sirtuin 2 and sirtuin 7 serum levels in the maternal and fetal cord blood were examined by enzyme-linked immunosorbent assay. RESULTS: It was found that sirtuin 7 in placenta accreta spectrum was significantly lower in the placenta compared to the control and placenta previa groups (p<0.05). However, a significant difference was not observed between the sirtuin 2 and sirtuin 7 levels in the maternal and fetal cord serum samples of those three groups (p>0.05). CONCLUSION: Sirtuin 7 may play an important role in the formation of placenta accreta spectrum. The effect of decreased expression of sirtuin 7 might be tissue-dependent in the placenta accreta spectrum and needs to be investigated further.

RESUMO

BACKGROUND Placenta previa is defined as a placenta that grows from the anterior or posterior wall of the uterus and covers the cervix. The incidence of placenta previa has been increasing in recent years. It is thought that bleeding is more common during surgery in cases with anterior placenta that is closing the cervix. This study investigated the importance of placental location in pregnant women with placenta previa who had a previous cesarean section. MATERIAL AND METHODS This study covered the period from July 2017 to June 2020. The 116 patients included in the study were divided into 2 groups according to placental location: anterior (group 1) and posterior (group 2). All patients had previously delivered via cesarean section. Operation time, presence of invasion, estimated blood loss during surgery, and transfused erythrocyte volume were evaluated. Medical records were used to access the relevant data. RESULTS The patients in group 1 and group 2 had an average of 2.71 and 2.01 previous cesarean sections, respectively (P=0.002). The placental invasion (percreta) rate was significantly higher in group 1 than in group 2 (65.4 vs 5.3%, P<0.001), as was the estimated blood loss during surgery (790 vs 527 mL, P=0.014). The total erythrocyte suspension was considerably higher in group 1 than in group 2 patients (0.8 vs 0.2, P=0.014), both during and after surgery. CONCLUSIONS In patients with placenta previa, the location of the placenta should always be examined with ultrasonography to allow better preoperative planning.

RESUMO

This study investigated patients who underwent bilateral hypogastric artery ligation (BHAL) due to postpartum haemorrhage (PPH). Patients who underwent BHAL because of PPH following a conservative treatment were included in this study. Placental abnormalities were referred to as placenta accreta. A total of 130 BHAL procedures took place at the study hospital as a result of PPH. Of these, 39 (30%) were referred to the hospital. The rate of BHAL requirement was 62 out of 10,000 births. Among the 130 patients, the most frequent indication for BHAL was placenta accreta (58.5%). Haematological parameters were poorer among the referral patients. Four of the exitus patients (80%) were referral patients. The mortality rate among the referral patients was 10.25%, whereas this rate was only 1.01% among the patients who gave birth at the hospital. PPH is a life-threatening condition that requires immediate medical attention. BHAL, with its fertility-preserving features, is a good option that can be employed in all PPH patients. BHAL not only preserves patients' fertility, but it also gives them a higher chance of survival.IMPACT STATEMENTWhat is already known on this subject? PPH is a life-threatening condition. Due to the worldwide increase in caesarean sections, placenta accreta has also increased. BHAL is a vital treatment method for PPH.What do the results of this study add? Placenta accreta is one of the most common causes of PPH. Traditional hysterectomy rates can be reduced by replacing this treatment with BHAL in this group of patients. Without early intervention in PPH, a patient's mortality risk can increase by up to 10 times. As research and surgeons' experience grows, PPH can be controlled with treatments with less complex modalities without the need for BHAL.What are the implications of these findings for clinical practice and/or further research? The need for BHAL should be kept in mind when addressing PPH, especially in cases of placenta accreta. The need for hypogastric artery ligation, which is a more aggressive treatment for the surgical correction of the pathology, can be reduced as surgeons' experience increases. Early intervention and/or referral in cases of PPH is of great importance.

RESUMO

OBJECTIVE: To investigate the levels of anti-angiogenic factors, namely sFlt-1 and Netrin-4, in patients with preeclampsia (PE). MATERIAL AND METHODS: Cord-blood (UC) sFlt-1 and Netrin-4 concentrations were measured in 30 patients with severe PE, 30 patients with PE and 30 control infants and their mothers (MS). RESULTS: Maternal sFlt-1 levels were significantly higher in the severe PE and PE groups than in the control group. There were no statistical differences among the three groups in maternal and fetal Netrin-4 levels. But Netrin-4 levels were found to be the lowest in the control group and higher in the PE and severe PE groups. The correlation analysis revealed a positive correlation between maternal sFlt-1 levels and maternal Netrin-4 levels (p = 0.012, and r = 0.263), maternal sFlt-1 levels and fetal sFlt-1 levels (p = 0.012, and r = 0.263). CONCLUSIONS: There was a positive correlation found between maternal sFlt-1 levels and maternal Netrin-4 levels. We are of the opinion that elevation in levels of Netrin-4 might be secondary to placental hypoxia occurring in PE. The present study led to the consideration of anti-angiogenic biomarkers (sFlt-1 and Netrin-4) on automated platforms for clinical use as an aid in establishing the diagnosis and prognosis of PE.

RESUMO

OBJECTIVES: The most important step in laparoscopic surgery is to safely establish the pneumoperitoneum, especially since approximately half of the complications occur during the initial entry into the abdomen. There is a distinct need to modify the available methods to reduce therate of adverse events in laparoscopic entry. In this study, a modified Veress technique (MVT) or Evsen method is introduced.The aim of this article was to present a modified Veress technique for establishing the pneumoperitoneum. MATERIAL AND METHODS: The study was conducted at the Dicle University, Faculty of Medicine, Department of Obstetrics and Gynecology, from September 2016 to May 2017. A new laparoscopic entry technique was introduced and compared with the classical Veress technique. A total of 40 cases were included in the study. MVT and the classical Veress method were applied to 26 and 14 patients, respectively. RESULTS: The pneumoperitoneum was established at the first attempt in 23 (88.5%) MVT patients and in 7 (50%) patients from the classical Veress method group. The number of insufflation attempts to establish a successful pneumoperitoneum was lower using MVT and the difference was statistically significant (p: 0.022). As far as time is concerned, a comparison between the groups revealed that the pneumoperitoneum was established in a statistically significantly shorter time using MVT (p < 0.00). CONCLUSIONS: The modified Veress technique proved to be superior to the classical Veress method for establishing the pneumoperitoneum. Using the new method, the pneumoperitoneum was established after fewer attempts and in a shorter time.

RESUMO

BACKGROUND/AIM: The purpose of this study was to prove the effect of complete surgical staging of patients with mucinous borderline ovarian tumors (mBOTs) especially appendectomy on progression-free survival (PFS) and overall survival (OS). PATIENTS AND METHODS: The database of 14 gynecological oncology departments from Turkey and Germany were comprehensively searched for women who underwent primary surgery for an ovarian tumor between January 1, 1998, and December 31, 2015, and whose final diagnosis was mBOT. RESULTS: A total of 364 patients with mBOT with a median age of 43.1 years were included in this analysis. The median OS of all patients was 53.1 months. The majority of cases had Stage IA (78.6%). In univariate and multivariate analyses, radical surgery, omentectomy, appendectomy, lymphadenectomy, and adding adjuvant chemotherapy were not independent prognostic factors for PFS and OS. Furthermore, FIGO stage (≥IC vs.

RESUMO

BACKGROUND: The optimal surgical management and staging of borderline ovarian tumors (BOTs) are controversial. Institutions have different surgical approaches for the treatment of BOTs. Here, we performed a retrospective review of clinical characteristics, surgical management and surgical outcomes, and sought to identify variables affecting disease-free survival (DFS) and overall survival (OS) in patients with BOTs. METHODS: A retrospective review of ten gynecological oncology department databases in Turkey was conducted to identify patients diagnosed with BOTs. The effects of type of surgery, age, stage, surgical staging, complete versus incomplete staging, and adjuvant chemotherapy were examined on DFS and OS. RESULTS: In total, 733 patients with BOTs were included in the analysis. Most of the staged cases were in stage IA (70.4 %). In total, 345 patients underwent conservative surgeries. Recurrence rates were similar between the conservative and radical surgery groups (10.5 % vs. 8.7 %). Furthermore we did not find any difference between DFS (HR = 0.96; 95 % confidence interval, CI = 0.7-1.2; p = 0.576) or OS (HR = 0.9; 95 % CI = 0.8-1.1; p = 0.328) between patients who underwent conservative versus radical surgeries. There was also no difference in DFS (HR = 0.74; 95 % CI = 0.8-1.1; p = 0.080) or OS (HR = 0.8; 95 % CI = 0.7-1.0; p = 0.091) between complete, incomplete, and unstaged patients. Furthermore, receiving adjuvant chemotherapy (CT) for tumor stage ≥ IC was not an independent prognostic factor for DFS or OS. CONCLUSIONS: Patients undergoing conservative surgery did not show higher recurrence rates; furthermore, survival time was not shortened. Detailed surgical staging, including lymph node sampling or dissection, appendectomy, and hysterectomy, were not beneficial in the surgical management oF BOTs.

RESUMO

AIM: The aim of this study was to investigate the potential association between neural tube defects and paraoxonase-1 activity in amniotic fluid. We studied total oxidant status, total antioxidant capacity, paraoxonase-1 activity and thyroid hormone amniotic fluid concentration in fetuses with neural tube defects. METHODS: The present study was performed at the Department of Obstetrics and Gynaecology and the Department of Clinical Biochemistry of Dicle University between September 2011 and June 2013. The study group included 37 amniotic fluid samples from pregnant women (16-20 weeks of gestation) with fetuses affected by neural tube defects. The control group consisted of 36 pregnant women who were diagnosed with a high-risk pregnancy according to first or second trimester aneuploidy screening and were later confirmed on amniocentesis to have genetically normal fetuses. RESULTS: Amniotic fluid paraoxonase-1 activity and total oxidant status were significantly higher (P = 0.023, P = 0.029, respectively) whereas free T4 was significantly lower (P = 0.022) in fetuses with neural tube defects compared with control subjects. In fetuses with neural tube defects, amniotic fluid paraoxonase-1 activity correlated positively with total oxidant status (r = 0.424**, P = 0.010), and amniotic fluid total antioxidant capacity correlated positively with free t4 (r = 0.381*, P = 0.022). CONCLUSION: This is the first study in the literature to show an association between paraoxonase-1 activity and thyroid hormone concentration and neural tube defects.

RESUMO

AIM: The purpose of this study was to investigate the protective effect of honokiol on experimental ischemia/reperfusion injury of rat ovary. MATERIALS AND METHODS: A total of 40 female Wistar albino rats were used in this study. The rats were divided into five groups as follows: sham (Group I), torsion (Group II), torsion + detorsion (Group III), torsion + detorsion + saline (Group IV), and torsion + detorsion + honokiol (Group V). Bilateral adnexa in all the rats except for those in the sham group were exposed to torsion for 3 hours. The rats in Group IV were administered saline, whereas the rats in Group V were administered honokiol by intraperitoneal route 30 minutes before detorsion. Tissue and plasma concentrations of malondialdehyde and nitric oxide were determined. Ovarian tissue was histologically evaluated. Data analyses were performed by means of Kruskal-Wallis test and Mann-Whitney U-test (Bonferroni correction) in SPSS 15.0 (Statistical Package for Social Sciences; SPSS Inc., Chicago, IL, USA). RESULTS: The torsion and detorsion groups had higher scores in vascular congestion, hemorrhage, and inflammatory cell infiltration compared with the sham group (P<0.005). In addition, total histopathological scores were significantly higher in the torsion and detorsion groups compared with the sham group (P<0.005). A significant reduction was observed in hemorrhage, inflammatory cell infiltration, and cellular degeneration scores, of all histopathological scores, in the honokiol group (P<0.005). Ovarian tissue concentrations of malondialdehyde were significantly higher in the torsion and detorsion groups compared with the sham and honokiol groups (P<0.005). Ovarian tissue concentrations of nitric oxide, on the other hand, were significantly higher in the torsion group compared with the sham, saline, and honokiol groups (P<0.005). CONCLUSION: Honokiol has a beneficial effect on ovarian torsion-related ischemia/reperfusion injury.

RESUMO

AIM: To investigate whether serum levels of neopterin and inflammatory markers including C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and oxidative status indicators were altered in patients with hyperemesis gravidarum (HG) compared to asymptomatic pregnant women. METHODS: This cross-sectional study was performed including 30 pregnant women with HG (mean age: 30.67 ± 6.68) and 30 asymptomatic pregnant women (mean age: 28.00 ± 5.30). Demographic features, obstetric history, and the Pregnancy Unique Quantification of Emesis/Nausea (PUQE) index were noted. Complete blood count, serum biochemical assay and measurement of CRP, TNF-α, IL-6, total antioxidant status and total oxidative status (TOS) levels were taken and compared between groups. RESULTS: White blood cell count (P = 0.013), platelet count (P = 0.015), TOS (P < 0.001), and PUQE score (P < 0.001) were remarkably higher in HG pregnancies. On the other hand, serum levels of lactate dehydrogenase, (P < 0.001), sodium (P < 0.001), potassium (P < 0.001), chloride (P < 0.001) and TAS (P < 0.001) were higher in the control group. There was no difference in the levels of neopterin, CRP, TNF-α and IL-6. In patients with HG, a positive correlation was detected between TOS and serum levels of lactate dehydrogenase, while TNF-α, IL-6 and neopterin were positively correlated with hemoglobin levels. CONCLUSION: Our results demonstrated no association between inflammation and HG. Elucidation of the pathophysiology and complex interaction between various inflammatory processes in HG necessitates further trials on larger series.

RESUMO

OBJECTIVE: The aim of this study was to elucidate the etiology and treatment of primary ovarian insufficiency, which is of unknown cause in 95% of the cases. MATERIALS AND METHODS: Thirty patients aged 18-40 years who presented to Dicle University Faculty of Medicine Clinic of Obstetrics and Gynecology between June 2012 and January 2014 and were diagnosed as having primary ovarian insufficiency based on their clinical and endocrinologic data, and 30 healthy controls were included in this study. RESULTS: No significant differences were found between patients with primary ovarian insufficiency and control subjects in demographic data and lipid profile levels, thyroid- stimulating hormone, prolactin, and glucose. However, the neutrophil to lymphocyte ratio and levels of follicle-stimulating hormone, luteinizing hormone, total antioxidant status, total oxidant status, and oxidative stress index were significantly higher in patients with primary ovarian insufficiency than in control subjects. In the correlation analysis, follicle-stimulating hormone exhibited a positive correlation with total oxidant status, oxidative stress index, and the neutrophil to lymphocyte ratio (r=0.573** p<0.001, r=0.584** p<0.001, r=0.541 p<0.001, respectively) and correlated negatively with total antioxidant status (r=-0.437** p<0.001). CONCLUSION: The neutrophil to lymphocyte ratio, total oxidant status, and oxidative stress index levels are elevated in primary ovarian insufficiency. Therefore, anti-oxidative and anti-inflammatory treatment might be administered to patients in the early stage of primary ovarian insufficiency. However, larger studies are needed to clarify whether these elevated levels are a cause or a consequence of primary ovarian insufficiency.

RESUMO

INTRODUCTION: The aim of this study was to investigate whether estradiol (E2), E2 combined with progesterone (Prog) (E2/Prog), and genistein (Gen) treatment had antioxidative and anti-hyperlipidemic effects in the plasma of ovariectomized (OVX) rats. MATERIALS AND METHODS: Adult female Sprague-Dawley rats were divided into five groups. Rats in all groups, except for those in a sham group, underwent bilateral ovariectomy under general anesthesia. The groups were as follows: sham group; control OVX group; group treated with estrogen (0.014 mg/kg 17-ß E2); group treated with a combination of E2 and Prog (0.014 mg/kg 17-ß E2 plus 0.028 mg/kg drospirenone), and group treated with Gen (10 mg/kg/day). Plasma of rats of each treatment group was analyzed to determine the total antioxidant status, total oxidant status, paraoxonase activity, lipid profile, high-density lipoprotein (HDL-chol), low-density lipoprotein (LDL-chol), total cholesterol (Total-C), triacylglycerols, lipoprotein (a), and oxidative stress index. RESULTS: Plasma Total-C levels and body weight increased in all the OVX groups compared with the sham group (P<0.005). The group treated with E2 had significantly elevated total oxidant status, oxidative stress index, LDL-chol, and Total-C compared with the control group (P<0.005). Gen treatment might lead to lower LDL-chol and Total-C levels compared with E2 treatment. CONCLUSIONS: Gen treatment might be preferred to E2 treatment for treatment of menopausal symptoms in patients at risk for cardiovascular diseases. However, considering the small sample size of this study, larger studies are needed in this area.

RESUMO

AIM: The purpose of this study was to investigate the effectiveness of honokiol, a natural molecule that was shown to have antioxidant effects, in prevention of intra-abdominal adhesion formation in a rat model. MATERIAL AND METHOD: This study was conducted on a total of 40 non-pregnant Sprague-Dawley rats, which were divided into 4 groups as follows: sham, control, saline, and honokiol groups. Both uterine horns of the rats in control, saline, and honokiol groups were exposed and a 2-cm segment of the anti-mesenteric surface of both uterine horns was traumatized by a scalpel. The saline group was administered 2 ml of saline/day intraperitoneally for 5 days after the operation. The honokiol group, on the other hand, was administered honokiol intraperitoneally at a dose of 1 mg/kg/day for 5 days after the operation. On postoperative day 14, 3 ml of intracardiac blood sample was taken from the rats for biochemical analyses, and the rats were sacrificed this way. RESULTS: Adhesion and inflammation scores were significantly lower in the honokiol group compared with the saline and control groups (p < 0.008). Similarly, fibrosis score was significantly lower in the honokiol group compared with the saline group (p < 0.008). CONCLUSION: Honokiol was found to be effective in prevention of intra-abdominal adhesion formation in a rat model. However, larger studies are needed to shed light on the exact role of honokiol in intra-abdominal adhesion formation and to determine the molecular aspects of the promising results found in this study.

RESUMO

OBJECTIVE: To compare ''vaginal hysterectomy alone'' with ''vaginal hysterectomy with prophylactic unilateral sacrospinous ligament fixation'' in terms of intraoperative complications and 1-year anatomic outcomes and symptoms in patients aged over 50 years who presented with stage 3 or 4 pelvic organ prolapse (POP). MATERIALS AND METHODS: Thirty-five patients underwent vaginal hysterectomy alone and 32 patients underwent vaginal hysterectomy with unilateral sacrospinous ligament fixation because of benign pathology between January 2012, and June 2014, were retrospectively analyzed in this study. The patients' demographic data and preoperative and intraoperative findings were obtained from the hospital records and noted. The patients were invited by phone to a follow-up visit to assess their 1-year anatomic outcomes and symptoms. RESULTS: There was no significant demographic difference between the patients who underwent vaginal hysterectomy alone and those who had a vaginal hysterectomy with sacrospinous ligament fixation. Both length of operation and hospital stay were significantly longer in the patients who underwent vaginal hysterectomy with sacrospinous ligament fixation (p<0.001); intraoperative complications requiring blood transfusion were also significantly more frequent in these patients compared with the patients who underwent vaginal hysterectomy only (p=0.048). Recurrence of vaginal vault prolapse was significantly more frequent in the patients with vaginal hysterectomy alone compared with those who had both vaginal hysterectomy and sacrospinous ligament fixation (p=0.035). CONCLUSION: Unilateral sacrospinous ligament fixation might be added to vaginal hysterectomy in patients with stage 3 or 4 POP who are predicted to have long survival times. However, further studies with a larger sample size are needed in this area of research.

RESUMO

OBJECTIVE: To evaluate the maternal and fetal demographic features and clinical aspects of twin pregnancies with single intrauterine demise. MATERIALS AND METHODS: This retrospective study was conducted in Dicle University Faculty of Medicine, Department of Gynecology and Obstetrics between January 2008 and December 2013. There were a total of 594 twin deliveries in our hospital between the given dates. Twenty-nine of these cases were referred to our hospital by another health center because of a preliminary diagnosis of single intrauterine demise. Maternal age, parity, chorionicity, week of fetal death, gestational week at delivery, mode of delivery, birth weight, Activity, pulse, grimace, appearance, respiration scores, maternal fibrinogen levels at delivery and during pregnancy, stay in the neonatal intensive care unit, and obstetric complications were explored in these 29 cases of single intrauterine demise. RESULTS: The mean age of the 29 patients who were provided antenatal follow-up and delivery services in our hospital was 29.9±6.5 years. Thirteen (44.8%) of the patients were monochorionic, whereas 16 (55.2%) were dichorionic. Intrauterine fetal death occurred in the first trimester in 6 pateints and in the second or third trimester in 23. In addition, 20 (69%) patients underwent cesarean section, whereas 9 (31%) had spontaneous vaginal delivery. Lastly, none of the patients had a maternal coagulation disorder. CONCLUSION: Twin pregnancies with single intrauterine death can lead to various complications for both the surviving fetus and the mother. Close maternal and fetal monitoring, and proper care and management can minimize complications.

RESUMO

AIM: The purpose of this study was to evaluate the diagnostic methods, predisposing risk factors and surgical treatment options in patients with translocation of intrauterine devices (IUD). MATERIAL AND METHODS: Diagnosis, predisposing factors and treatment of 34 patients with translocation of IUD was evaluated in this retrospective study. RESULTS: Complaints of pain during insertion and history of cesarean section were present in 70.5% and 58.8% of patients, respectively. IUD-related complications were detected in 52.8% of patients. Transvaginal ultrasonography was used to detect translocation of IUD in 55.8% of cases. Laparoscopy was performed in 55.8% of patients. CONCLUSION: There were high rates of history of cesarean section, insertion in the puerperal period and insertion by midwives in patients with translocated IUD. These may be predisposing factors for IUD translocation. The clinician who inserts the IUD should be experienced in this area and obtain sufficient information from the pelvic examination prior to insertion of the device. Gynecological examination should be conducted for a proper diagnosis of translocation of IUD. In the event that the IUD string is not visible in the gynecological examination, transvaginal ultrasonography should be performed. If the IUD is still not visible, then abdominal radiography should be performed. As soon as diagnosis of translocation of IUD has been established, surgical treatment should be planned. First treatment of choice should be laparoscopy.
