RESUMO

Background/aim: Proinflammatory chemokines have been shown to play crucial roles in implantation, spiral artery invasion, and the fetomaternal immunological response. In this context, we investigated the levels of fractalkine (CX3CL1) and chemokine CC motif ligand 4 (CCL4 or MIP-1ß) in maternal serum and amniotic fluids in pregnant women with intrauterine growth restriction (IUGR). Materials and methods: This prospective cohort study was carried out at Firat University Obstetrics Clinic between January 1, 2022 and July 1, 2022. Group (G) 1: The control group consisted of 40 pregnant women who underwent elective cesarean section (CS) at 38-40 weeks of gestation. G2: A total of 40 pregnant women with IUGR at 28-37 weeks of gestation were included in the study group. Levels of tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1ß), interferon-gamma (IFN-γ), hypoxia-inducible factor-1 alpha (HIF-1α), macrophage inflammatory protein-1 beta (MIP-1ß), and fractalkine were measured in maternal serum and amniotic fluid samples obtained during CS. Results: When maternal age was compared, no statistically significant difference was observed between G1 and G2 (p = 0.374). The number of gravidity was found to be statistically higher in G1 compared to G2 (p = 0.003). The mean gestational week was statistically higher in G1 (p < 0.001). Maternal serum MIP-1ß (p = 0.03) and IFN-γ (p = 0.006) levels were higher in G1. The birth weight of the baby (p < 0.001) and umbilical cord blood gas pH value (p < 0.001) at birth were higher in G1. HIF-1α (p < 0.001), fractalkine (p < 0.001), MIP-1ß (p < 0.001), TNF-α (p = 0.007), IL-1ß (p < 0.001), and IFN-γ levels (p = 0.007) in amniotic fluid were higher in G2. Conclusion: Elevated levels of proinflammatory factors, including fractalkine and MIP-1ß, along with inflammatory factors such as TNF-α, IL-1ß, and IFN-γ, as well as increased HIF-1α levels in amniotic fluid, are associated with intrauterine growth restriction (IUGR) attributed to a hypoxic amniotic environment.

RESUMO

Background/Aim: Surfactant is a surface-active substance that, in addition to its detergent effect, also has effects that reduce inflammation and fibrosis. Because of these effects, it was aimed herein to investigate the effect of intraperitoneal surfactant application on preventing postoperative peritoneal adhesion formation in a uterine horn adhesion model. Materials and methods: Twenty-one Wistar albino rats were randomly divided into 3 groups (G1-G3), as follows: G1 (n = 7): control group. The abdomen was opened and then closed; G2 (n = 7): adhesion group. The abdomen was opened. Then, a 2-cm linear incision was made over the right uterine horn, 2 mL of isotonic saline was administered intraperitoneally, and the abdomen was closed; and G3 (n = 7): treatment group. The abdomen was opened, a 2-cm linear incision was made over the right uterine horn, 2 mL (70 mg/kg) of surfactant was administered intraperitoneally, and the abdomen was closed. After 15 days, the rats were euthanized, the abdomens were reopened, and adhesion scoring was performed. After the right uterine horns were removed and fixed with 10% formalin, appropriate sections were taken from the traumatized tissue, stained with Masson's trichrome, and fibrosis and inflammation scoring were performed. Results: The adhesion area and intensity were significantly higher in G2 than in G1 and G3 (p = 0.001) and were similar in G1 and G3 (p = 0.165). While fibrosis and inflammation were significantly higher in G2 than in G1 and G3 (p = 0.001), there was no difference between G1 and G3 (p = 0.5). Conclusion: Intraperitoneal surfactant administration at a dose of 70 mg/kg was found to be effective in preventing intraabdominal adhesion formation in a rat uterine horn model.

RESUMO

Background/aim: Ovarian hyperstimulation syndrome (OHSS) is a complication of ovarian stimulation with increased vascular endothelial growth factor (VEGF) and vascular permeability in the ovarian tissue. Transient receptor potential melastatin 2 (TRPM2) is known to be associated with angiogenesis and vascular permeability. In this experimental study, we aimed to investigate the activity of TRPM2 in the development of OHSS. Materials and methods: Fourteen immature female rats were divided into two groups. Group 1 was the control group, and Group 2 was the OHSS group that was exposed to 10 IU of subcutaneous application of FSH for four days and 30 IU of human chorionic gonadotropin (hCG) on the 5th day. At the end of the experiment, the ovaries were removed. The right ovarian tissues were stored in 10% formol for histopathological and immunohistochemical examination. The left ovarian tissues were stored at ­80 °C for biochemical examinations. VEGF, tumor necrosis factor-alpha (TNF­α) and malondialdehyde (MDA) levels were measured in the ovarian tissue. Congestion, edema, apoptosis and TRPM2 immunoreactivity were evaluated. Results: There was a significant increase in ovarian weight in the OHSS group compared to the control group. There was a significant increase in congestion, edema, apoptosis and TRPM2 immunoreactivity in the OHSS group. A significant increase in tissue levels of VEGF, TNF­α and MDA was also found in the OHSS group compared to the control group. Conclusion: As a result of our experiment, it was found that increased TRPM2 immunoreactivity on hyperstimulated rat ovary may be the reason or result of edema and congestion. Further studies are needed to discuss our results.

RESUMO

This study describes the purse-string suture technique using a mini-Pfannenstiel incision for the surgical treatment of large ovarian dermoid cysts. We investigated intra and postoperative outcomes in 24 patients who underwent removal of large ovarian dermoid cysts through a mini-Pfannenstiel incision using the purse-string suture technique. The surgical procedure was performed by two experienced surgeons. The mean diameter of the cysts was 11.9 cm. The mean operation time was 46 min and the intraoperative rupture rate was 8.3%. No patient developed chemical peritonitis. The length of hospitalisation was 36 h. The recurrence rate was 8.3% in the same ovary at 1-year follow-up. In conclusion, ovarian dermoid cysts measuring >8 cm in diameter can be effectively treated through a mini-Pfannenstiel incision using the purse-string suture technique.Impact StatementWhat is already known on this subject? Dermoid cysts are the most common ovarian germ cell tumours occurring in the second and third decades of life, and these tumours are usually treated surgically. There is a lack of consensus among gynaecologists regarding the optimal surgical treatment modalities for ovarian dermoid cysts; however, laparoscopic cystectomy is the gold standard for the surgical treatment of dermoid cysts. Notably, aspiration of dense cystic contents may be difficult during laparoscopic cystectomy.What do the results of this study add? Our technique enables easy removal of dense cystic materials including hair and bone fragments. The short operation time, low recurrence rate and the minimal incisional scar serve as advantages of our novel method.What are the implications of these findings for clinical practice and/or further research? This surgical technique can be successfully used in clinical settings with limited facilities for laparoscopic surgery.

RESUMO

Background and aim: To compare the effects of bilateral proximal tubal occlusion and bilateral total salpingectomy on ovarian reserve and the cholinergic system via rat experiment. Materials and methods: Twenty-one adult female rats were randomly divided into the following three groups:G1 (n = 7), sham group;G2 (n = 7), bilateral total salpingectomy group; and G3 (n = 7), bilateral proximal tubal occlusion group. Four weeks later, the abdomen of the rats was opened. The right ovarian tissues were stored in 10% formaldehyde, whereas the left ovarian tissues were stored at ­80 °C in aluminum foil. Serum samples were evaluated for antimullerian hormone. The right ovary was used for histological and immunoreactive examination, and the left ovary was used for tissue MDA analysis. Tissue samples were analyzed for MDA levels with spectrophotometric measurement, apoptosis with TUNEL staining, fibrosis score with Mason trichrome staining, ovarian reserve with HE staining, and cholinergic receptor muscarinic 1 (CHRM1) level with immunoreactivity method. Results: Compared to G1 and G3, the number of corpus luteum with secondary follicles was significantly lower in G2, whereas the number of ovarian cysts and fibrosis and apoptosis scores increased significantly. The CHRM1 immunoreactivity was significantly lower in G2 than in G1 and G3. Conclusions: Compared to the bilateral proximal tubal occlusion performed by using bipolar cautery, bilateral total salpingectomy in rats leads to a significant damage in ovarian histopathology and the cholinergic system.

RESUMO

This study aimed to evaluate the effects of coasting, cabergoline and clarithromycin in a rat ovarian hyperstimulation syndrome (OHSS) model. The 42 female Wistar rats were divided into seven groups: control, OHSS (was given 10 IU of pregnant mare serum gonadotropin for 4 consecutive days from day 22 and 30 IU hCG on the fifth day to induce OHSS ), coasting (hCG was applied on the 27th day after gonadotropin injections and the rats were decapitated on the 28th day), Cabergoline (100 mg/kg/d) and clarithromycin (100 mg/kg/d) were given (on the 26th day) with a short-term supplementation (on the 26th day) and long-term supplementation (from the 22nd to the 26th day) groups. The rats were decapitated on the 27th day. Cabergoline and clarithromycin significantly lowered VEGF-2 levels. Clarithromycin significantly reduced IL-1b and TNF-a and significantly increased IL-10 levels. Clarithromycin may be an effective drug for the treatment of OHSS. Impact statement What is already known on this subject? Ovarian hyper-stimulation syndrome (OHSS) is a self-limited disease, in which vascular endothelial growth factor (VEGF) plays the most important role and has a large clinical spectrum related with increased capillary permeability and fluid retention. Some treatment methods that block VEGF over-expression are used in treatment of OHSS. Clarithromycin is known to suppress the production of some pro-inflammatory molecules such as VEGF, IL-8, IL-1, IL-6 and TNF-a. In our study, we compared the efficacy of coasting, short- and long-term supplementation of clarithromycin and cabergoline on correcting OHSS parameters in an experimental study. What do the results of this study add? As a result of our study, we found that OHSS parameters improved better in early prophylactic treatment regimens. We have shown that clarithromycin may be a more effective treatment agent than coasting and cabergoline. What are the implications of these findings for clinical practice and/or further research? Although our study is important in that it is the first pilot study to show that clarithromycin is effective in the treatment of OHSS, there is a need for larger clinical trials.

RESUMO

Background/aim: The purpose of this study was toinvestigate the effects of 10% povidone­iodine (PI) sclerotherapyon ovarian cyst diameter through an experimental study. Materials and methods: To be able to create ovarian cysts, right unilateral salpingectomy was performed on 20 Wistar albino rats. One month after the operation, the abdomens of all rats were reopened. Sixteen rats with macroscopic ovarian cysts were divided randomly into 2 groups consisting of 8 rats. Group 1 (G1): the cyst content was only aspirated. Group 2 (G2): the ovarian cyst was aspirated and then the cystic cavity was irrigated with PI. Abdomens of all rats were closed and 1 month later they were reopened. Tissues of the right ovaries of the rats were embedded in paraffin blocks for histopathological examination. Follicle count, fibrosis, and congestion were evaluated under a light microscope. Results: For G1, there was no difference in cyst diameters before and after aspiration. In G2, a decrease was observed in cyst diameter. There was no difference in ovarian reserve between the 2 groups. When compared with G1, an increase in fibrosis and congestion was determined in G2. Conclusion: Sclerotherapyinto the ovarian cyst for a 5-min period using 10% PI reduces cyst diameter without any change in ovarian reserve.

RESUMO

Background/aim: This study compared TRPM2 and TRPM7 ion channel gene expression and immunohistochemical staining in endometrial hyperplasia and endometrium adenocarcinoma. Materials and methods: Sections were taken from paraffin blocks of 120 patients who were divided into 6 groups as follows: G1 (n = 20), proliferative endometrium (PE); G2 (n = 20), EH without atypia; G3 (n = 20), EH with atypia; G4 (n = 20), stage 1A, grade 1 EC; G5 (n = 20), stage 1A, grade 2 EC; and G6 (n = 20), stage 1A, grade 3 EC. TRPM2 and TRPM7 genes were analyzed with qRT-PCR in paraffin-embedded tissue samples. Under light microscopy, TRPM2 and TRPM7 immunostaining scores of the samples taken from polylysine slides were evaluated. Results: Compared to G1, TRPM2 mRNA gene expression was significantly downregulated in G3 and G5. TRPM2 immunoreactivity scores were similar in all groups. TRPM7 mRNA gene expression was significantly downregulated in G2, G3, and G6 when compared to G1. TRPM7 immunoreactivity scores were similar in G1, G2, and G3, but significantly decreased in G4, G5, and G6 Conclusion: Reduction in TRPM7 ion channel activity may be a progression marker for endometrial hyperplasia regardless of the atypical criteria.

RESUMO

The aim of this study is to define a new method of manipulating the uterus during laparoscopic hysterectomy. A total laparoscopic hysterectomy (TLH) with the newly defined technique was performed in 29 patients between July 2016 and July 2017. In this new technique, the uterus was bound from uterine corpus and fundus like a bridle with polyester tape, to allow abdominal manipulation. The technique was successfully performed at the first attempt in 93.1% of cases. It was repeated in two cases (6.9%) since the polyester tape departed away from the uterus at the first attempt. The mean application time was 11.2 min. The vaginal manipulator was not required in any of the cases. There were no intraoperative complications. In conclusion, this method has the advantages of not requiring any vaginal manipulator, reducing the number of people required during operation, permitting a near maximum manipulation of the uterus in all three dimensions, and giving the control of these manipulations directly to the surgeon. On the other hand, the technique also has some inadequacies which should be discussed and improved on in the future. Impact of statement What is already known on this subject? In a laparoscopic hysterectomy, manipulation of the uterus is essential for anatomical dissection of the regions and completion of the operation without complications. An ideal uterine manipulator is defined as inexpensive, as convenient, fast and suitable for injecting solutions, removing the need for an assistant and most importantly offering the most suitable range of motion. In this study, we describe a new and different technique (rein technique) allowing the abdominal manipulation of the uterus in a laparoscopic hysterectomy and discuss the advantages and disadvantages of this method. What do the results of this study add? The procedure was easily accomplished in most patients. We did not need to use an extra uterine manipulator in any of the cases. What are the implications of these findings for clinical practice and/or further research? In conclusion, the rein technique of uterine manipulation is effective and safe.

RESUMO

The aim of this study was to compare the effects of only aspiration with aspiration and 5% trichloroacetic acid (TCA) application on ovarian cyst size and ovarian reserve. The ovarian cysts of 14 rats that were divided into two groups randomly were investigated after total salpingectomy procedure. G1 was the group of saline application after cyst aspiration, while in G2, after aspiration 5% TCA at half amount of aspiration volume was injected into the cyst and re-aspirated after five minutes. The abdomens of the rats were closed and re-explored after 1 month. The cyst diameters of the rats in each group were measured. Ovaries were removed for histopathological examination. There was no significant difference in cyst diameter in G1 before and after aspiration. In G2, there was a significant decrease in cyst size after TCA application. Ovarian follicle counts were not significantly different between the two groups. In conclusion, application of 5% TCA to the ovarian cysts for five minutes significantly reduces the cyst size. Impact Statement What is already known on this subject: Minimally invasive therapies come into prominence to avoid surgical complications and diminished fertility in the treatment of ovarian cysts. USG-guided aspiration and sclerosis has been reported as cost-efficient and effective treatment methods for localised benign cysts in other organs such as the thyroid, parathyroid, liver, kidney and spleen. It has been shown that sclerotherapy applied to infertile women with ovarian cysts reduces pelvic pain without affecting the number of follicles, term pregnancy and abortion rates, extracted oocytes, embryo quality or hormonal levels when compared to non-ovarian cystic infertile women. TCA is a chemical agent that is topically applied, not systemically absorptive, which causes denaturation of proteins and structural cell death, resulting in coagulation necrosis after chemical cauterisation. For this reason, we used 5% TCA to treat simple ovarian cysts on a rat model. What the results of this study add: In this experimental study, we showed that the application of 5% TCA into the cyst for five minutes - then aspirated - significantly reduced the size of the ovarian cysts. Five percent TCA application did not affect the ovarian reserve. What the implications are of these findings for clinical practice and/or further research: Our study is original because of the fact that to the best of our knowledge, this is the first study about the use of 5% TCA in treatment of ovarian cysts in the literature.

RESUMO

The aim of this study was to compare the postoperative results of the patients who were treated with Bakri balloon tamponade or hysterectomy for placenta accreta and increta. Patients who were diagnosed with placenta accreta or increta preoperatively and intraoperatively and treated with Bakri balloon tamponade (Group 1) or caesarean hysterectomy (Group 2) were compared in regards to the postoperative results. Among the 36 patients diagnosed with placenta accreta or increta, 19 patients were treated with Bakri balloon tamponade while 17 cases were treated with hysterectomy. Intraoperative blood loss amount was 1794 ± 725 ml in G1, which was lower than that in G2 (2694 ± 893 ml). Blood transfusion amount was 2.7 ± 2.6 units in G1, lower than that in G2 (5.7 ± 2.4 units), too. Operation time was 64.5 ± 29 min and 140 ± 51 min in G1 and G2, respectively, showing significant differences between two groups. The success rate of Bakri balloon was determined as 84.21%. In conclusion, cases with placenta accreta/increta, with predicted placental detachment who are willing to preserve fertility, application of uterine balloon tamponade devices before the hysterectomy is encouraging with its advantages compared with the hysterectomy. Impact statement What is already known on this subject: Invasive placental anomalies are the most common indication of postpartum hysterectomy. Recently, uterine balloon tamponade was also included in the treatment modalities of postpartum haemorrhage.This study aimed to compare the postoperative results of UBT or hysterectomy for patients with placenta accreta and increta. What the results of this study add: In this study, the total amount of blood loss was higher in the caesarean hysterectomy group when compared with the Bakri balloon tamponade group. The mean transfusion requirement, mean operation time and hospitalisation period was significantly longer in the caesarean hysterectomy group. The success rate of the Bakri balloon was determined as 84.21%. Two patients who were treated with balloon application had a successful pregnancy and delivery later. Maternal mortality was reported in neither balloon nor hysterectomy groups. What the implications are of these findings for clinical practice and/or further research: In conclusion, patients diagnosed with placenta accreta/increta with ultrasound should be taken into the operation in elective conditions, if possible, on lithotomy position. In cases with predicted placental detachment that are willing to preserve fertility, application of uterine balloon tamponade devices before the hysterectomy has advantages compared with the hysterectomy.

RESUMO

There are several methods used for non-surgical sterilization in birth control including quinacrine, trichloroacetic acid (TCA), erythromycin, tetracycline, silver nitrate and talcum powder. Among these, talcum powder, TCA and silver nitrate are the most commonly used. However, the toxic and carcinogenic activities of these chemicals in ovarian tissue have been poorly elucidated. This study demonstrates the expression levels of antioxidant, apoptotic and anti-apoptotic genes after administration of talc powder, TCA and silver nitrate for non-surgical sterilization in female rat models. The expression changes of some microRNAs (miR-15b, miR-21, miR-34a and miR-98) that play key roles in the apoptosis pathway were also included. All expression analyses were evaluated with real-time PCR. The expression levels of all genes appeared to be upregulated in the talcum powder group, but the results were not statistically significant. Increased expression of Gsr and Sod1 genes was statistically significant in the talcum powder group. In TCA and silver nitrate group, expression of all genes was appeared to be elevated but only the Gsr expression was statistically significant in the TCA-administrated group; there were no statistically significant changes in the silver nitrate group. miRNA expression levels were increased in talcum powder and TCA-administrated groups, but these results were not significant. Expression levels of miR-15b, miR-21 and miR-98 in the silver nitrate group were significantly increased. Consequently, these chemicals appear to be non-carcinogenic agents for rat ovarian tissue which do not induce apoptosis. However, talcum powder and TCA can be considered as agents that are toxic to ovarian tissue.

RESUMO

AIM: To investigate the effectiveness of intraperitoneal vitamin C (VC) and vitamin E (VE) in the prevention of postoperative adhesion formation in a rat uterine horn model. METHODS: Twenty-eight Wistar albino rats were divided into four groups in which: control group, the abdomen was opened and closed without any intervention; adhesion group, a 2-cm linear incision was performed on the uterine horn and closed; VC group, VC was administrated i.p., and 15 min later a 2-cm incision was performed on the uterine horn and closed; and VE group, VE was administrated i.p., and 15 min later a 2-cm incision was performed on the uterine horn and closed. Re-laparotomy was performed 15 days later. Right uterine horn adhesions were evaluated according to macromorphological characteristics and tissue sections were further examined for fibrosis, angiogenesis and vascular endothelial growth factor (VEGF), type I collagen and malondialdehyde (MDA) scoring. Kruskal-Wallis anova and Mann-Whitney U-test were utilized for statistical analysis. RESULTS: Adhesion area and also strength were significantly lower in the VC group and the VE group compared with the adhesion group. Fibrosis and angiogenesis scores were observed to be significantly higher in the adhesion group compared with the VC group and the VE group. MDA and VEGF immunoreactivity were also found to be significantly lower in the VC group and the VE group compared with the adhesion group. However, there was no significant difference between the VC group and the VE group with respect to all the above parameters. CONCLUSION: Administration of VC or VE i.p. was observed to be effective in the prevention of postoperative adhesion formation in an experimental model.

RESUMO

In the present study, effects on expression of antioxidant, apoptotic and anti-apoptotic genes (GSR, GRX3, SOD1, RAI-NOS, HSP7, BAX, Bcl-2, CASP3 and MDH1) of substances being used in non-surgical sterilization such as quinacrine, erythromycin and tetracycline were evaluated in over tissue. Moreover, expression of some specific mi-RNA (miR-15b, miR-21, miR34a and miR-98) that playing a role in apoptosis was determined in same tissue. Prospective comparative experimental study. Genetics and Histology laboratory. Total number of 28 Wistar albino 12-14 week old female rats with regular cycles and 200-220 grams in weight. Total RNA was isolated from tissues by using a RNA isolation kit. Gene expression levels were evaluated by Real-Time PCR method. Tubal passage and fibrosis induction in tissues was observed in the histochemical analysis. In the statistical analysis of data Kruskal-Wallis variance analysis and Mann-Whitney U test were used and p < 0.05 were accepted as significant. While the expressions of target genes found to be increased in quinacrine and erythromycin group when compared to control group, this increase was insignificant. In quinacrine group, increase in the SOD1 expression levels was only statistically significant (p < 0.05). Expression levels of miR-15b, miR-21, miR34a and miR-98 microRNAs were found to be up-regulated in all experimental groups, despite this, only the increased expression miR-34 was found as statistically significant when compared to control. Tubal blockage and fibrosis induction scores of quinacrine, erythromycin and tetracycline were significantly higher than control. Results of the present study suggest that the doses treated of quinacrine, erythromycin and tetracycline used in non-surgical sterilization effect poorly the expression of anti-oxidant, apoptotic and anti-apoptotic genes, but the expression of miR-34 playing the role in apoptosis increased after treatment of these substances.

RESUMO

AIM: To evaluate and compare analgesic efficacy, drug consumption and patient satisfaction with the i.v. patient-controlled and continuous infusion modes of administration of tramadol. METHODS: A total of 40 pregnant women in American Society of Anesthesiologists physical status classification system risk classes I-II scheduled for cesarean section were randomized into two groups to receive treatment in single-blind fashion. Patients in both groups received tramadol as an i.v. infusion 15 min before the end of surgery under general anesthesia for cesarean section. In the post-anesthesia care unit, the 20 patients allocated to group I were given i.v. tramadol in patient-controlled anesthesia (PCA), while the 20 other patients assigned to group II received it as a continuous infusion. Pain visual analog scores (VAS), mean arterial pressure (MAP), heart rate, total tramadol consumption, sedation scores, side-effects (nausea/vomiting) and patient satisfaction were evaluated seven times in the course of the first postoperative 24 h. The Mann-Whitney U-test and Friedman's anova were used for the statistical treatment of data. RESULTS: VAS, sedation scores and nausea/vomiting scores were similar in both groups (P > 0.05). The 24-h tramadol consumption was significantly lower in group I (420.15 ± 66.58 mg) than in group II (494.00 ± 29.45 mg), while patient satisfaction was significantly higher in group I (P < 0.05). CONCLUSION: While tramadol administration by either of the methods used may ensure efficient early postoperative anesthesia in cesarean section patients, i.v. PCA may be preferred because of the lower drug consumption and higher patient satisfaction associated with it.

RESUMO

PURPOSE: Endometrial biopsy preceding implantation in in vitro fertilization (IVF) treatment causes a type of injury which facilitates implantation. Pre-treatment hysteroscopic evaluation of uterine cavity also raises the success in IVF. This study investigates whether office hysteroscopy and concurrent endometrial biopsy performed in the luteal phase, on the day of GnRH agonist initiation for long protocol, improves subsequent IVF outcome. METHODS: A prospective, nonrandomized, controlled study of 128 normoresponder women was performed: In 70 women (study group), office hysteroscopy and concurrent endometrial biopsy were performed on the day of GnRH agonist initiation preceding ET cycle and in 58 women (control group), GnRH agonist was initiated without any intervention. However, uterine cavity was shown to be normal with hysteroscopy within the previous 6 months in those women. Implantation and pregnancy rates were compared between the groups. RESULTS: Intrauterine pathologies were observed in 28 % of women in the study group. Implantation rate (38 vs. 25 %; p = 0.04) and pregnancy rate per ET (67 vs. 45 %; p = 0.01) were found to be significantly higher in the study group compared to the control group. CONCLUSION: Office hysteroscopy and concurrent endometrial biopsy performed in the luteal phase, on the day of GnRH agonist initiation for long protocol, provide direct evaluation of the uterine cavity immediately before ET cycle and also significantly improve the implantation and IVF outcome.

RESUMO

BACKGROUND/AIMS: In our study, the effect of hyaluronan synthase 2 (HAS2) and CD44 immunoreactivity as a predictive biomarker in the prediction of progesterone-resistant endometrial hyperplasia (EH) cases without atypia was investigated. SETTINGS AND DESIGN: In this retrospective study, HAS2 and CD44 immunoreactivity in the endometrial tissues of 60 patients diagnosed with EH and treated with progesterone and 20 patients diagnosed with proliferative endometrium (PE) were evaluated. MATERIALS AND METHODS: Eighty patients were divided into four groups. Group 1 (G1) (n = 20) = PE group, G2 (n = 20) = EH group without atypia, G3 (n = 20) = group with continued EH with treatment, G4 (n = 20) = EH with treatment without atypia. STATISTICAL ANALYSIS: Intergroup evaluation was done with One-way ANOVA and posthoc tukey test. P < 0.05 values were considered statistically significant. RESULTS: The HAS2 immunoreactivity score of G2 and G3 was higher than G1 and G4. On the other hand, there was no difference between G1 and G4. When G2 and G3 were compared, HAS2 immunoreactivity scores were significantly increased in G3. When CD44 immunoreactivity was compared with G1, a significant increase was detected in G2, G3, and G4. However, CD44 immunoreactivity scores were similar in G2, G3, and G4. CONCLUSION: HAS2 immunoreactivity may be an immunohistochemical biomarker in predicting EH cases without atypia resistant to progesterone therapy. Since CD44 immunoreactivity is increased in all EH groups without atypia, it is not effective in predicting treatment resistance.

RESUMO

AIM: To compare the efficiency of endouterine hemostatic square suture and the Bakri balloon tamponade in the treatment of bleeding due to complete placenta previa (CPP). METHODS: Thirteen patients with the diagnosis of CPP and intractable bleeding were randomly divided into two groups in a single blind study. Group 1 (n=6) included patients in whom endouterine hemostatic square suture was applied, while group 2 (n=7) included patients in whom Bakri balloon tamponade was applied. The two groups were compared according to the maternal outcomes, the duration of caesarean section, the preoperative and the postoperative hemoglobin and hematocrit (Htc) values, the intraoperative and postoperative blood loss, as well as the newborn characteristics. RESULTS: The duration of operation and the amount of intraoperative bleeding were significantly higher in group 1 (time: 78.3 ± 8.1 vs. 62.8 ± 3.9 min; P<0.05; intraoperative bleeding: 1946 ± 242 vs. 1520 ± 92 mL; P<0.05). The postoperative 24th h Htc values were found to be significantly lower in group 1 than in group 2 (25.6 ± 3.7 vs. 29.5 ± 1.3 g/dL; P<0.05). The postoperative blood loss was higher in group 1 than in group 2. (351 ± 70 vs. 120 ± 56 mL; P<0.05). CONCLUSION: There are two methods that are effective in preventing bleeding in CPP. However, the Bakri balloon tamponade may be a better alternative due to a shorter operation time and less blood loss.

RESUMO

OBJECTIVES: This study aimed to compare the effects of N-acetylcysteine and benfotiamine in protection of ovarian tissue from ischemia caused by slow neovascularization injury due to intraperitoneal ovarian autotransplant in rats. MATERIALS AND METHODS: Twenty-eight female rats were divided into 4 groups, each containing 7 rats. Group 1 only had the abdomen opened and closed, group 2 was the transplant-only group, group 3 received benfotiamine for 3 weeks starting 1 day before the transplant procedure, and group 4 received N-acetylcysteine for 3 weeks starting 1 day before the transplant procedure. At the end of the experimental period, malondialdehyde levels in ovarian tissues together with the apoptosis and fibrosis, proliferating cell nuclear antigen and vascular endothelial growth factor immunoreactivity, and ovarian reserves were investigated. RESULTS: Apoptosis was significantly increased in group 2 animals. Primordial follicle count was higher in groups 3 and 4 than in group 2. Vascular endothelial growth factor immunoreactivity was decreased in groups 3 and 4 compared with group 2. Proliferating cell nuclear antigen immunoreactivity was reduced in the secondary follicles in all transplant groups. CONCLUSIONS: In autologous intraperitoneal ovarian transplant, both benfotiamine and N-acetylcysteine are equal and effective agents in protection of ovarian tissue against ischemic injury.

RESUMO

Objective: We look at the immunoreactivity of cholinergic receptor muscarinic 1 (CHRM1) in the ovarian tissues of rats with ovarian hyperstimulation syndrome (OHSS) considering the possibility that the muscarinic activity may contribute to the pathophysiology of OHSS. Materials and Methods: In this study, 14 immature female Wistar Albino rats were divided into two groups at random. The rats were 22 days old. Rats in the control group (n=7) were 22 days old, while those in the OHSS group (n=7) received 10 IU follicle-stimulating hormone subcutaneously over the course of four days and 30 IU human chorionic gonadotropin (hCG) on the fifth day to induce ovarian hyperstimulation. All the rats were sacrificed after all the groups' ovaries and blood samples were collected at the conclusion of the experiment. The left ovarian tissues were kept in aluminum foil at -80 °C, while the right ovarian tissues were kept in 10% formalin. Tissue vascular endothelial growth factor (VEGF), interleukin (IL)-1ß, IL-6, IL-10, tumor necrosis factor (TNF)-α and malondialdehyde (MDA) levels were measured by The Enzyme Linked Immunosorbent Assay technique in the ovarian tissues. CHRM1 immunoreactivity was scored immunohistochemically. Results: Ovarian weight, tissue IL-10, TNF-α, VEGF and MDA levels, and CHRM1 immunoreactivity were significantly increased in the OHSS group. Conclusion: Increased levels of CHRM1 activity may play a role in the pathophysiology of OHSS. With further studies, the effect of luteinizing hormone and hCG on the ovarian and hypothalamic cholinergic system can be further investigated, and useful information can be obtained in determining OHSS prevention strategies.
