OBJECTIVE To investigate the effectiveness of a single preoperative dose of misoprostol in abdominal myomectomies. DESIGN Placebo-controlled randomized prospective study. SETTING Department of obstetrics and gynecology in a university hospital. PATIENT(S) Twenty-five women with symptomatic uterine leiomyomas. INTERVENTION(S) Among patients undergoing abdominal myomectomies, an hour before the operation women in the study group (n = 13) were given a single dose of vaginal misoprostol (400 microg); those in the control group (n = 12) were given placebo. MAIN OUTCOME MEASURE(S) Intraoperative blood loss, duration of operation, duration of postoperative hospitalization, and the need for blood transfusion were compared between the control and study groups. RESULT(S) Blood loss, operation time, and need for postoperative blood transfusion were significantly reduced in the group given vaginal misoprostol. No difference was observed among patients in terms of the time of hospitalization. CONCLUSION(S) A single preoperative dose of vaginal misoprostol is a simple, reliable method for reducing intraoperative blood loss and need for postoperative blood transfusion after abdominal myomectomies.

Ekrem Sapmaz; Husnu Celik

OBJECTIVE To compare the effects of ligation of the ascending branches of the uterine artery and tourniquet methods intra-operative and post-operative hemorrhage during abdominal myomectomy. METHODS Fifty-one cases with symptomatic myoma uteri were prospectively, randomly assigned to two single blind groups. Myomectomy was performed in Group 1 (n=26) by bilateral ligation of the ascending branches of the uterine artery and in Group 2 (n=25) by the intra-operative tourniquet method. Mann-Whitney U, Wilcoxon Rank and chi(2) tests were used in the comparison of the data. Spearman correlation analysis was used to determine the correlation between myoma enucleation, operation duration and blood loss (r(s), P, n). RESULTS Operation time, number of removed myoma nuclei, (P>0.05, Mann-Whitney U test), and febrile morbidity were similar in the two groups (P>0.05, chi(2) test). Intra-operative blood loss was lower in Group 1 (P<0.05, Mann-Whitney U test). In three cases from Group 2 post-operative hemorrhage occurred, and the laparotomy and bilateral ligation of the internal iliac arteries were performed in these cases. There was a positive correlation among myoma enucleation, operation duration and blood loss (r(s)=0.7, P=0.001, n=51). CONCLUSIONS Intra-operative blood loss is lower with bilateral ligation of the ascending branches of the uterine artery during myomectomy. The effect of ligation on hemorrhage continues in the post-operative period.

Abstract Objective: To research the hypothesis of preeclampsia (PE) is associated with increased systemic inflammatory responses of Th1-type as well as decreased Th2-type responses; we evaluated the maternal plasma levels of IFN-gamma, TNF-alpha, TGF-beta, IL-4, IL-6, IL-10, IL-17, IL-35 and SOCS3 in preeclamptic and healthy pregnants. Methods: This study was conducted with 40 preeclamptic (study group) and 40 normotensive pregnant (control) women in third trimester when they were admitted to the labor and delivery unit. The extracted maternal plasma samples were assayed by an enzyme-linked immunosorbent assay. Statistical analysis was performed by SPSS 16.0 version. Results: While IFN-gamma and TGF-beta levels of preeclamptic women were significantly higher (p < 0.01), IL-35 and IL-17 levels of preeclamptic women were significantly lower (p < 0.01) than those of controls. The ratios of IFN-gamma/IL-10, IFN-gamma/IL-6, IFN-gamma/IL-4 were significantly high and ratio of IL-35/IL-17 was significantly low in the PE group compared to those in the control group. Maternal plasma SOCS3 levels showed negative correlation with blood pressure and proteinuria severity, but none of the cytokines showed influence on blood pressure and proteinuria after adjusting for maternal and gestational age. Conclusions: Increased IFN-gamma/TGF-beta production and reduced IL-35/IL-17/SOCS3 production in preeclamptic women may lead to less cytokine inhibitory activity in PE, which may account for the increased proteinuria and blood pressure in PE.

Implantation necessitates complex interactions among the developing embryo, decidualizing endometrium, and developing maternal immune tolerance and/or alterations in cellular and humoral immune responses. Overstimulation of T helper 1 (Th1) or Th2 cytokines in systemic and local environments, alterations of the prevalence of IL17 and regulatory T cell (Treg) cytokines have also been suggested to contribute to the pathogenesis of implantation failure. We aimed to investigate the plasma levels of IL4, IL6, IL10, TNFα, IFNγ, TGFβ, IL17, IL35, and SOCS3 in infertile and fertile women. This case-control study was conducted with 80 women suffering from unexplained infertility and 40 fertile women. Peripheral venous blood samples were drawn on day 21 of the menstrual cycle. The extracted plasma samples were assayed by an enzyme linked immunosorbent assay. Statistical analysis was performed using SPSS version 16.0. Our main findings were as follows: despite the significantly high IL17 and IL35 plasma levels of infertile women, IL35/IL17 ratio was significantly lower in the infertile group compared with that in the fertile group; SOCS3 plasma levels showed an inverse relation with plasma levels of all cytokines except IL35; increased plasma IL17 levels (>3.42 pg/mL) have a negative impact on fertility; TNFα/IL10, IFNγ/IL10, IFNγ/IL6, and IFNγ/IL4 ratios were significantly higher in infertile group compared with those in the fertile group. It is not possible to show the major immunological factor(s) of unexplained infertility, but our findings point out that the decreased suppressor activity of the immune system may play a role in implantation failure.

OBJECTIVE To investigate the regression level of simple ovarian cyst size after local ethanol application and the damage level of adjacent ovarian reserve in rats. STUDY DESIGN This study was conducted at Firat University Animal Laboratory with 18 mature (12-14 weeks old) female Wistar albino rats weighing 200-220g, with regular cycles. Ovarian cyst induction was performed with unilateral salpingectomy. Fourteen rats with ovarian cysts after a second laparotomy were divided into two groups as follows: Group 1 (n=7): cyst aspiration group, and Group 2 (n=7): intracystic 95% ethanol application group. One month after the cyst aspiration procedure a third laparotomy was performed. The cyst number and size were recorded for each rat. Right ovariectomy was performed and formalin-fixed/paraffin-embedded tissues were sectioned at 5μm thickness. Under light microscopy, ovarian total follicle reserve and fibrosis were evaluated with Masson trichrome staining and apoptosis was evaluated with TUNEL staining. The groups were compared with the Mann-Whitney U test and Wilcoxon Rank test. p<0.05 was considered significant. RESULTS Ovarian cyst formation was observed in 85% (15/18) of rats. The mean diameter of ovarian cysts in Groups 1 and 2 were, respectively, 10.3mm and 10.1mm. After aspiration, there was no significant reduction in the cyst diameter (10.3mm vs 8.1mm), but after ethanol application the diameter significantly reduced (10.1mm vs 3.4mm, p<0.05). Mean ovarian follicle count in Group 2 was significantly lower than in Group 1 (25 vs 42, p<0.05), and mean fibrosis and apoptosis scores in Group 2 were significantly higher than in Group 1 (2.5 vs 0.9, p<0.05). CONCLUSION Local ethanol application reduces cyst diameter but concomitantly decreases ovarian reserve due to increased fibrosis in rats. In humans, intracystic ethanol application should be performed cautiously.

Abstract Objective: To investigate the plasma levels of interleukin-4 (IL-4), IL-6, IL-10, tumor necrosis factor-alpha (TNF-alpha), interferon-gamma (IFN-gamma), transforming growth factor-beta (TGF-beta), IL-17, IL-35 and suppressor of cytokine signaling 3 (SOCS3) in the women with history of idiopathic recurrent pregnancy loss (RPL) and in the fertile controls. Methods: This study was conducted with 60 idiopathic RPL cases and 40 age-matched fertile controls. Mid-follicular plasma levels of IL-17, IFN-gamma, TNF-alpha, TGF-beta, IL-6, IL-4, IL-10, SOCS3 and IL-35 were assayed by an enzyme linked immunosorbent assay. Results: The mean age of RPL and control cases were 31.6 ± 0.6 and 32.1 ± 0.7 years, respectively. While plasma IL-35 and SOCS3 levels of RPL group were significantly lower than that of the control group; IFN-gamma, TNF-alpha, IL-4, IL-6, IL-10, IL-17 and TGF-beta levels of RPL group were significantly higher than that of the control group. The comparison of cytokine ratios between RPL and control groups indicated significantly high TNF-alpha/IL-10, TNF-alpha/IL-4, IFN-gamma/IL-10, IFN-gamma/IL-6 and IFN-gamma/IL-4 ratios in the RPL group. IL-35/IL-17 ratio was significantly low in the RPL group compared to that in the control group. Overstimulation of TNF-alpha presented moderate influence on recurrent miscarriage risk. Conclusion: Decreased SOCS3 and IL-35 plasma levels and increased Th1/Th2 cytokine ratios in RPL cases pointed out the supression of anti-inflammatory process and this supression might play an important role in the pathogenesis of idiopathic RPL.

Objective To examine the effects of low-to-high doses of tamoxifen on ovarian histopathology, serum VEGF, and endothelin 1 levels in ovarian hyperstimulation syndrome (OHSS) in an experimental setting. Materials and methods A total of 20 female Wistar albino rats, 22 days of age, were randomly divided into four groups. Follicle-stimulating hormone 10 IU was administered subcutaneously in 15 rats on 4 consecutive days, with OHSS induction on day 5 by 30 IU of human chorionic gonadotropin. Group 1 (n=5) comprised 35-day-old control rats, group 2 (n=5) 35-day-old OHSS rats, group 3 (n=5) 27-day-old OHSS rats receiving 1 mg/kg of oral tamoxifen for 7 days, group 4 (n=5) 27-day-old OHSS rats receiving 3 mg/kg of oral tamoxifen for 7 days. All rats were decapitated on day 35. Serum VEGF, endothelin 1, and ovarian follicular reserve were assessed in all rats. Kruskal–Wallis variance analysis and the Mann–Whitney U-test were used for statistical comparisons. A Bonferroni correction was performed to control the inflation of significance, with a significance level set at a P-value of less than 0.025. Results Despite higher serum VEGF, endothelin 1, follicular reserve, and angiogenesis and fibrosis of the corpus luteum in the OHSS group compared to controls, these differences were not significant (P>0.025, Mann–Whitney U-test). There was a significant reduction in the ovarian follicular reserve in tamoxifen groups compared to controls (P<0.025, Mann–Whitney U-test), while angiogenesis of the corpus luteum, number of atretic follicles, fibrosis, and serum VEGF were significantly higher in rats receiving tamoxifen (P<0.025, Mann–Whitney U-test). Also, significantly lower follicular reserve and fibrosis were observed among rats in the low-dose tamoxifen group in comparison with rats in the high-dose tamoxifen group (P<0.025, Mann–Whitney U-test). No groups had a significant change in endothelin 1 levels (P>0.025, Mann–Whitney U-test). Conclusion Tamoxifen 1 g and 3 g resulted in a dose-dependent increase in VEGF and endothelin 1 levels, and ovarian follicle reserves were significantly reduced in our experimental model.

Abstract 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.

Abstract Objective: To determine the serum tenascin-C (TN-C) levels in cases with mild and severe preeclampsia. Methods: Pregnant women were divided into three groups, namely healthy pregnants (Group 1, n = 20), pregnants with mild preeclampsia (Group 2, n = 20) and pregnants with severe preeclampsia (Group 3, n = 20). The groups were formed so as to match each other in terms of gestational week. From each pregnant woman, pre- and post-delivery blood samples were obtained to measure serum TN-C levels. The data were evaluated using the Kruskall–Wallis variance analysis. For the obtained values of p < 0.05, the groups were compared in pairs. A p value of < 0.017 was accepted as significant. Results: In Groups 1, 2 and 3, the prepartum TN-C levels were 5.02 ± 0.4 µg/ml, 12.8 ± 2.9 µg/ml and 33.8 ± 11.7 µg/ml, and in the postpartum TN-C levels were 4.7 ± 0.1 µg/ml, 11.7 ± 1.8 µg/ml and 50.6 ± 33.8 µg/ml, respectively. There was a significant difference between the groups in terms of the prepartum and postpartum TN-C levels (p < 0.017, Mann–Whitney U [MWU] test). There was also a significant difference in the prepartum TN-C levels between Groups 2 and 3 (p < 0.017, MWU test). Conclusions: The prepartum and postpartum TN-C levels were significantly higher in mild and severe preeclampsia than those in healthy pregnants.
