Asymmetrical dimethylarginine levels on the implantation success of in vitro fertilization and embryo transfer.

The aim of this study was to evaluate the level of asymmetrical dimethylarginine (ADMA) levels before gonadotrophine treatment and on the day of oocytes retrieval in order to determine whether ADMA can be used as a predictive marker for implantation success in in vitro fertilization (IVF) cycles. Forty-four unexplained infertile patients were included in the study. Controlled ovarian hyperstimulation was performed using the recombinant follicle-stimulating hormone (FSH) with the standard long protocol for all patients. ADMA and E2 were measured at the beginning of the ovulation induction and on oocyte retrieval day. The primary outcome was the difference in ADMA levels in implantation positive and implantation negative women. At the beginning of the ovulation induction, the mean ADMA levels were 1553 µmol/L and 1.464 µmol/L in the implantation positive and negative groups, respectively. There was no statistically significant difference between groups (p: 0.90). On the day of oocyte retrieval, the mean ADMA levels were 1173 µmol/L and 1170 µmol/L in the implantation positive and negative groups, respectively. There was no statistically significant difference between groups (p: 0.97). In conclusion, ADMA levels before gonadotrophine treatment and the day of oocytes retrieval cannot be used as a predictive marker for implantation success in IVF cycles.

Chitotriosidase levels in patients with severe endometriosis.

OBJECTIVE: To study the levels of chitotriosidase activity in the peritoneal fluid and the plasma of patients with severe endometriosis and control subjects. MATERIALS AND METHODS: Twenty-five women with laparoscopically and histopathologically confirmed endometriosis (study group) and 27 control patients who had undergone laparoscopic surgery were included. Peritoneal fluid and peripheral blood were obtained from all the patients before the surgery. Chitotriosidase activities were measured. RESULTS: Analysis of chitotriosidase activity in the peritoneal fluid of patients with endometriosis showed that there was no significant difference between endometriosis and control group, respectively (32.04 ± 64.20 vs. 15.25 ± 31.17 nmol/mL/h; p > 0.05). Analysis of chitotriosidase activity in plasma of patients with endometriosis showed significantly increased levels of chitotriosidase levels compared with the control group (74.81 ± 60.54 vs. 14.10 ± 26.17; p < 0.001), respectively. CONCLUSION: We found that the activity of chitotriosidase in plasma was statistically higher in severe endometriosis patients than women without endometriosis.

Comparison of risk of malignancy index (RMI), CA125, CA 19-9, ultrasound score, and menopausal status in borderline ovarian tumor.

OBJECTIVE: The aim of this study was to assess the prognostic values of risk of malignancy index (RMI IV), ultrasound score, menopausal status, and serum CA125 and CA19-9 level in patients with borderline ovarian tumor (BOT). METHODS: Fifty women having borderline ovarian tumor (BOT) and 5O individuals with benign adnexal mass were enrolled in this retrospective study. The sensitivity, specificity, positive predictive values, negative predictive values and diagnostic accuracy of preoperative serum levels of the CA125 and CA19-9, ultrasound findings and menopausal status, and RMI IV were calculated for prediction of discrimination between BOTs and benign adnexal masses and the results were compared. RESULTS: The RMI IV was the best method for discrimination between BOTs and benign adnexal masses and was more accurate than the other parameters. When Receiver Operator Characteristic area under the curves for menopausal status was analyzed, serum CA 125 and CA19-9 level, ultrasound score, RMI IV(CA125), and RMI IV(CA19-9) were, 0.580, 0.625, 0.548, 0.694, 0.734 and 0.711, respectively. The best RMI IV cut-off was found to be 200 for discrimination of benign and BOT lesions. In the RMI formulation, replacing CA125 with CA19-9 didn't affect RMI IV sensitivity and specificity for discrimination. CONCLUSION: Compared to ultrasound, menopausal status, CA-125, CA19-9, the RMI IV was found to be the best predictive method for differentiation of BOTs from benign adnexal masses. RMI IV cut-off value of 200 is suitable for differentiation of benign and BOT's.

Chitotriosidase, interleukin-1 beta and tumor necrosis factor alpha levels in mild preeclampsia.

OBJECTIVE: Chitotriosidase (ChT) is an activated macrophage marker. Tumor necrosis factor alpha (TNF-α) and interleukin 1 beta (IL-1ß) are mainly produced macrophages. The aim of the present study was to evaluate the relationship between serum ChT activity, levels of TNF-α and IL-1ß in patients with mild preeclampsia and normal pregnancy. METHODS: An overall 64 cases, 32 healthy pregnant control women (control group) and 32 women with mild preeclamptic patients (study group), were enrolled in this study. At the beginning of the study, all study participants were matched for age and gestational age. Serum ChT activity was measured by fluorometer; TNF-α and IL-1ß levels were measured by enzyme-linked immunosorbent assay. RESULTS: The mean age, gestational week, parity and gravida were similar in the two groups (p > 0.05). Serum ChT activity was significantly higher in the preeclampsia group compared to the control group (p < 0.05). Levels of TNF-α and IL-1ß in patients with mild preeclampsia were similar compared to the control group (p > 0.05). In the PE group, serum ChT activity was not correlated with TNF-α and IL-1ß. CONCLUSION: Mild preeclampsia is found associated with higher ChT activity. This result suggests that activated macrophages play a role in the pathogenesis of preeclampsia. This suggestion needs to be confirmed in future studies with larger populations.

Combined approach in a large placental chorioangioma case with intratumoral alcohol injection, cordocentesis, IU transfusion, and amnioreduction.

Large placental chorioangiomas (LPCs) are rare complications of pregnancy and these tumors are associated with increased risk of pregnancy complications. We presented a LPC case at 25th week of gestation, complicated by polyhydramnios and preterm labor in which intratumoral alcohol injection was performed succesfully. Cordocentesis, fetal intrauterine transfusion, and amnioreduction were performed at the same session, as a combined approach. The safety of the procedure was shown by the lack of alcohol in the fetal cord blood sample. Intratumoral alcohol injection is a reliable and effective treatment modality in the management of LPCs and may be combined with other invasive procedures.

Intrauterine pregnancy after laparoscopic tubal sterilization with bipolar electrocoagulation: a case report.

BACKGROUND: Although ectopic pregnancies, nonviable missed abortions or blighted ova may occur subsequent to female sterilization, intrauterine pregnancy has not been reported. The sterilization failure risk persists for years after the procedure and varies by operator technique, method of tubal occlusion and female age. CASE: A viable, 8-week intrauterine pregnancy developed in a 36-year-old woman, gravidity 3, parity 2, five years after laparoscopic tubal sterilization. CONCLUSION: The possible mechanisms for a pregnancy after tubal sterilization may be spontaneous reanastomosis or fistula formation or a viable endosalpinx caused by the failure of electrocoagulation. Operator failure may occur when the occluding device is placed on the round ligaments. In this case study, the pregnancy was most likely related to a possible fistula formation which could have developed over the years following surgery.

Comparison of different preoperative sublingual misoprostol regimens for surgical termination of first trimester pregnancies: a prospective randomized trial.

OBJECTIVE: To determine the appropriate dose of sublingual misoprostol administration before dilation and curettage (D&C) of the uterus in first trimester pregnancies. STUDY DESIGN: Ninety nulliparous women who underwent surgical termination of first trimester pregnancy were analyzed prospectively. The first group (n = 30) received a single 200-microg dose, and the second (n = 30) and third (n = 30) groups were administered 2x 200 microg (400 microg) and 3 x 200 microg (600 microg) doses of misoprostol sublingually, respectively, with 1-hour intervals. The main outcomes evaluated were the degree of difficulty of cervical dilation, adverse effects of misoprostol according to dose administered, and participant satisfaction rate with the procedure. RESULTS: The improvement in cervical dilation and the ease of the D&C procedure were more significant in the 600-microg misoprostol arm (p = 0.008). Because the prevalence and severity of the side effects of misoprostol were increased in a dose-dependent manner, the 400-microg arm was found to be the most efficient dose of the study with its high satisfaction rate (p < 0.001). CONCLUSION: Premedication with misoprostol makes the D&C procedure easier by leading to cervical ripening. By sublingual route 400 microg of misoprostol regimen seems to be appropriate for planned first trimester surgical pregnancy termination under local anesthesia. Misoprostol should be administered only to select and hospitalized patients.

Antimullerian hormone levels after laparoscopic endometrioma stripping surgery.

OBJECTIVE: To evaluate whether a change takes place in antimullerian hormone (AMH) levels reflecting the ovarian reserve after laparoscopic endometrioma stripping surgery and to demonstrate if there is any correlation between AMH levels and the sizes of endometriomas. METHOD: Fourty-seven women participated as the study group in this prospective controlled trial, 33 of whom (70.2%) had unilateral and 14 (29.7%) of whom had bilateral endometriomas. Pre- and post-operative serum AMH levels were measured and compared with 17 normo-ovulatory control cases and also correlated with endometrioma sizes. RESULT(S): Mean pre-operative AMH levels of the study group and the normo-ovulatory control cases did not reveal a statistically significant difference (1.62 +/- 1.09 ng/ml and 2.06 +/- 0.51 ng/ml, P > 0.05). Mean level of post-operative serum AMH of the study group decreased from 1.62 +/- 1.09 to 1.39 +/- 1.16. However, this reduction was not statistically significant. (P > 0.05). Pre- and post-operative AMH levels do not reveal a correlation with the size of endometrioma in both group of patients with either unilateral or bilateral endometrioma. CONCLUSION(S): The presence of the endometrioma does not impair the AMH levels. Laparoscopic endometrioma stripping surgery do not appear to cause a damage in the AMH secreting healthy ovarian tissue, in the short-term follow-up. Laparoscopic stripping surgery of endometriomas in experienced hands is currently a valid approach.

Successful twin pregnancy achieved by assisted reproductive technology in a patient with polycystic ovary syndrome with complex atypical endometrial hyperplasia treated with levonorgestrel-releasing intrauterine system.

Polycystic ovary syndrome (PCOS) is one of the most common reproductive endocrinopathy and a major cause of infertility. PCOS may be associated with chronic anovulation and endometrial hyperplasia. Conservative treatment should be considered in young women wishing to preserve their fertility. Standard treatment for complex endometrial hyperplasia is the use of high-dose progesterone, whereas we preferred levonorgestrel-releasing intrauterine system (LNG-IUS) as a last resort in our patient who was resistant to oral gestagens. We present a case with complex atypical endometrial hyperplasia treated conservatively in a long-term period first by oral gestagens, then by LNG-IUS. In our case, LNG-IUS was more effective than oral systemic progestins, not only for reducing the menstrual blood loss but also for improving the pathological findings. After extraction of LNG-IUS rapid achievement of pregnancy was carried out by intracytoplasmic sperm injection and embryo transfer and she took home twin babies. To the best of our knowledge, this is the first successful twin pregnancy case with ICSI and ET in a patient with oral gestagen resistant endometrial complex/atypical hyperplasia achieved after application of LNG-IUS. In complex atypical hyperplasia, LNG-IUS should be kept in mind as an effective alternative treatment modality before assisted reproductive technology (ART).

Serum vitamin B12 and homocysteine levels in pregnant women with neural tube defect.

OBJECTIVE: The aim of the study is to investigate the importance of serum vitamin B12 levels in pregnant women with foetal neural tube defect (NTD). STUDY DESIGN: This study consists of 31 pregnant women having fetuses with NTD. The pregnant women in the study group were selected among cases with normal folate levels. Serum vitamin B12 levels were investigated. Additionally, complete blood count, serum iron level, iron binding capacity, ferritin, folate, free T(3), free T(4), thyroid stimulating hormone and plasma homocysteine levels were measured. Control group consisted of 32 pregnant women who did not have a history of NTD in previous pregnancies and did not have fetuses with NTD in present pregnancy. NTD was diagnosed between 14th and 20th gestational age. The mean gestational age of members of control group was the same as those of NTD group. RESULTS: There was no statistically significant difference between pregnants with NTD and control group according to number of cases with vitamin B12 deficiency. CONCLUSION: It seems that vitamin B12 deficiency does not play a causative role in the development of foetal NTD. Monitoring maternal homocystein levels might be important in understanding the aetiologies of foetal NTD.

Herniation of fallopian tube through perforated uterine wall during previous first trimester surgical abortion in an infertile patient.

A unique case of fallopian tube herniation into the endometrial cavity after dilatation and curettage is presented. A 28-year-old patient who had secondary infertility for 2 years following dilatation and curettage without any other specific complaint was evaluated by laparoscopy and hysteroscopy. During these procedures, herniation of the right tube and infundibulopelvic ligament into the uterine cavity were observed. The herniation was repaired through a minilaparotomy incision.

Assessment of the predictive value of serum progesterone levels on early pregnancy prognosis in spontaneous twin gestations: a prospective study.

OBJECTIVES: The aim of this study was to assess the predictive value of serum progesterone levels in early pregnancy prognosis in spontaneous dichorionic-diamniotic twin gestations. STUDY DESIGN: This study was carried out among 38 spontaneous dichorionic-diamniotic twin gestations between January 2003 and June 2005 in the Department of Obstetrics and Gynaecology at the Gulhane Military Medical Academy. Serum progesterone levels were measured at 7 and 10 weeks' gestation and pregnancies were followed until 14 gestational weeks by ultrasound examination. RESULTS: We found that a progesterone level of 58 nmol/l in the 7th gestational week and of 51 ng/ml at 10 gestational weeks has a predictive value for viable intrauterine twin pregnancies with 83% sensitivity and 69% specificity and 83% sensitivity and 84% specificity, respectively. CONCLUSION: Progesterone levels in the early gestational weeks may be a biochemical marker for the prediction of a twin pregnancy outcome and may reduce the number of ultrasound examinations.

Anticipated and perceived pain from midtrimester amniocentesis.

OBJECTIVE: To evaluate the anticipated and perceived pain and determine the factors contributing to pain perception in women undergoing midtrimester amniocentesis. METHODS: A visual analog scale was used to quantify pain in this prospective study of 64 women undergoing amniocentesis in the same clinical setting. The analysis was done using the paired-samples t test, analysis of variance, the Kruskal-Wallis test, the Mann-Whitney U test, and Pearson correlation analysis. RESULTS: The postprocedural pain scores were significantly less than the preprocedural pain scores (P<0.01). Parity, a previous amniocentesis, the indication for amniocentesis, and the previous loss of a child were factors contributing to pain scores. No correlations were found between pain score and maternal age, week of pregnancy at the time of the procedure, parity, or having lost a child. CONCLUSION: The perceived pain was less than the anticipated pain, and the factors contributing to pain should be kept in mind when counseling patients undergoing midtrimester amniocentesis.

Retrieval of zona-free immature oocytes in a woman with recurrent empty follicle syndrome: a case report.

BACKGROUND: Different ovulation trigger methods such as gonadotropin releasing hormone-agonist (GnRH-a) and recombinant human chorionic gonadotropin (r-hCG) plus rescue oocyte retrieval might reveal oocytes in patients with recurrent empty follicle syndrome. CASE: Endogenous luteinizing hormone was triggered with a GnRH-a (Buserelin [Suprefact pro-injection, Aventis-Pharma, Turkey], 250 microg subcutaneously) in a GnRH antagonist (Cetrorelix [Cetrotide 0.25, SeronoTurkey], 0.25 mg/d, starting on day 6), down-regulated cycle. At the first scheduled retrieval, 3 cumulus-oocytecorona complexes were recovered from the left ovary. During chemical denudation with hyaluronidase, 2 of them underwent lysis. The third was a zona-free, germinalvesicle-stage oocyte after mechanical denudation. Oocyte pickup was stopped, and recombinant human chorionic gonadotropin (hCG) (250 microg subcutaneously) was injected. Five cumulus-oocyte-corona complexes were retrieved from the right ovary 24 hours after rescue with recombinant hCG. Only mechanical denudation was done, and 4 zona-free oocytes with germinal vesicle breakdown were seen. All oocytes underwent intracytoplasmic sperm injection, and none of them were fertilized. CONCLUSION: Oocyte maturation defects should be included in etiologic mechanisms for counseling patients with empty follicle syndrome.

Outcome of in vitro fertilization and ovarian response after endometrioma stripping at laparoscopy and laparotomy.

OBJECTIVE: To add further data on in vitro fertilization (IVF) outcome and ovarian response after endometrioma stripping via either laparoscopy or laparotomy. STUDY DESIGN: IVF outcome and ovarian response parameters in patients who had undergone unilateral endometrioma stripping at laparoscopy (n=28) or laparotomy (n=10) before IVF were retrospectively compared. RESULTS: Fertilization rates, number of embryos transferred and pregnancy rates did not differ between the groups. Significantly more recombinant FSH was used to induce folliculogenesis, and fewer metaphase II oocytes were retrieved in the laparotomy group. The laparotomy-postcystectomy ovaries were significantly smaller and malpositioned. In both stripping groups, significantly smaller operated-on ovaries with lower numbers of antral and mature follicles were observed as compared to intact ovaries. CONCLUSION: A higher amount of FSH is needed to achieve an acceptable IVF outcome after unilateral endometrioma surgery. Indications for surgical treatment of patients having larger and bilateral cysts with an expectation for future fertility should be cautiously reviewed
