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.

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.

Toluidine blue staining in the diagnosis of endometrial pathologies: a preliminary study before chromohysteroscopy.

OBJECTIVE: To assess the efficacy of toluidine blue (TBlue) staining in the detection of endometrial premalignant or malignant lesions in uterine specimens obtained from hysterectomies. We hoped that the results of this preliminary study would help us in our future studies which may be on chromohysteroscopy. STUDY DESIGN: We developed an endometrium staining technique in which TBlue solution was used as a vital dye. The study enrolled 50 patients. Of these, 20 patients known to have a premalign or malign lesion of the uterus constituted the study group and 30 patients were recruited as the control group who were operated for leiomyoma of the uterus. Immediately after hysterectomy, all specimens were dyed with TBlue solution and a frozen section procedure was performed on the positively stained areas. The pre- and post-operative histopathological diagnoses of the participants were compared and the reliability of the new method was calculated. RESULTS: The sensitivity of TBlue staining in the determination of endometrial pathologies was 100% (95%, CI 0.83-1) with a specificity of 90% (95%, CI 0.74-0.96). As a diagnostic test, the positive predictive value (PPV) was 87% with a negative predictive value (NPV) of 100%. The positive likelihood ratio (+LR) was 10 (95%, CI 3.41-29.2). CONCLUSIONS: Our preliminary results demonstrated that TBlue staining of endometrium is a reliable and highly sensitive technique that may be used in the frozen section examination of uterine specimens if a malignancy is suspected. Moreover, TBlue staining of endometrium may prove useful in hysteroscopy, although the technique, interpretation, and indications require further studies.

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 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.

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.

Comparison of four malignancy risk indices in the detection of malignant ovarian masses.

OBJECTIVE: The aim of this study was to evaluate the ability of four risk of malignancy indices (RMI) to detect malignant ovarian tumors. METHODS: This is a prospective study of 100 women admitted to the Department of Obstetrics and Gynecology of Gulhane Military Medicine Academy for surgical exploration of pelvic masses. To diagnose malignant ovarian tumors, the sensitivity, specificity, negative and positive predictive values and diagnostic accuracy of four RMIs (RMI 1, RMI 2, RMI 3, and RMI 4) were obtained. RESULTS: In our study we found that there is no statistically significant difference in the performance of four different RMIs in discriminating malignancy. We think that malignancy risk indices is more reliable than the menopausal status, serum CA-125 levels, ultrasound features and tumor size separately in detecting malignancy. CONCLUSION: We concluded that any of the four malignancy risk indices described can be used for selection of cases for optimal therapy. These methods are simple techniques that can be used even in less-specialized gynecology clinics to facilitate the selection of cases for referral to an oncological unit.

Differences in prevalence of sexual dysfunction between primary and secondary infertile women.

OBJECTIVE: To examine the impact of type of infertility on female sexual function. DESIGN: Comparison of female sexual function index and prevalence in primary infertile women and secondary infertile women. SETTING: Hospital. PATIENT(S): One hundred twenty-two primary infertile and 51 secondary infertile women. INTERVENTION(S): Questionnaires (Female Sexual Function Index [FSFI] and Beck Depression Inventory). MAIN OUTCOME MEASURE(S): Prevalence of dysfunction in primary and secondary infertile women. RESULT(S): The prevalence of female sexual dysfunction was 64.8% (n = 79) and 76.5% (n = 39) in primary infertile and secondary infertile women, respectively. In analyses of mean overall and subgroup scores of FSFI, there were significant differences between primary and secondary infertile women in the mean scores of orgasm, satisfaction, and total FSFI. Backward logistic regression identified a model with four significant predictors of sexual dysfunction (group, age, income level, and educational level). Secondary infertile women had a 9.5-fold higher risk of sexual dysfunction than primary infertile women after adjustment for confounding factors. CONCLUSION(S): There was a higher prevalence of sexual dysfunction in secondary infertile women. Secondary infertile women have decreased sexual desire, orgasm, and satisfaction compared with primary infertile women.

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.

Ultrasonographic evaluation and anti-mullerian hormone levels after laparoscopic stripping of unilateral endometriomas.

OBJECTIVE: To evaluate the ovarian reserve after laparoscopic stripping of unilateral endometriomas by comparing the operated and non-operated ovaries. STUDY DESIGN: Bilateral ovarian volumes, antral follicle counts, and stromal blood flows were assessed by ultrasonography and anti-mullerian hormone (AMH) levels were analysed in 36 patients who had undergone laparoscopic cystectomy for unilateral ovarian endometrioma. RESULTS: Mean antral follicle counts (AFC) of the operated side ovaries were significantly lower on the second postoperative day (3.1 ± 2.4 vs 5.2 ± 3.7; p<0.05) and in the third month (3.7 ± 2.1 vs 6.4 ± 2.7; p<0.05). Pulsatility indices of the operated ovaries were significantly decreased on the second postoperative day (2.22 ± 0.46 vs 1.76 ± 0.51; p<0.05) while resistance indices were increased (0.81 ± 0.06 vs 0.88 ± 0.13; p<0.05). Doppler parameters had recovered and a non-significant decrease in AMH levels of the patients was recorded in the third month after surgery (2.03 ± 0.41 ng/mL vs 1.95 ± 0.62 ng/mL; p>0.05). CONCLUSION: Although laparoscopic stripping of endometriomas seems to affect the ovarian reserve in terms of AFCs, it does not have a significant negative impact at the end of three months as assessed by ovarian volumes, Doppler indices and AMH levels. Endometrioma surgery techniques are important in preserving normal functioning ovaries and further studies are necessary for optimising these surgical approaches.

Lidocaine spray in addition to paracervical block reduces pain during first-trimester surgical abortion: a placebo-controlled clinical trial.

BACKGROUND: A variety of anesthetic and analgesic techniques have been used for uterine aspiration, and most clinicians use a paracervical block with or without additional analgesia. We intended to evaluate whether the addition of 10% lidocaine spray to a paracervical block decreases pain during cervical dilation and uterine aspiration. STUDY DESIGN: Seventy-seven patients were divided into two groups: paracervical blocks (PCB) (n = 30) and PCB plus 10% lidocaine spray (n = 47). Anticipated and overall perceived pain scores were measured with a standard Visual Analog Scale (VAS). RESULTS: Anticipated pain VAS scores of two groups were similar, however overall perceived pain VAS scores demonstrated a significant difference. PCB with Lidocaine only group had 6.56 ± 1.43 cm mean VAS score, whereas lidocaine plus lidocaine spray group had 2.35 ± 1.39 cm, the difference being statistically significant (p < .01). CONCLUSION: We found that 10% lidocaine spray safely decreases perceived pain during first-trimester surgical abortion, when used in addition to PCB with lidocaine HCl.

Comparison of aromatase inhibitor (letrozole) and immunomodulators (infliximab and etanercept) on the regression of endometriotic implants in a rat model.

OBJECTIVE: Novel treatment strategies are needed in the treatment of endometriosis due to limited success rates with the currently available options. As inflammatory and immunological mechanisms have been shown to be involved in the mechanism of the disease, new modalities are likely to emerge. We investigated the effects of infliximab (INF), etanercept (ETA) and letrozole on the regression of experimental endometriosis. STUDY DESIGN: In this experimental randomized trial, endometriosis was induced surgically in 44 adult female Sprague-Dawley rats. Establishment of implants was confirmed in 41 animals by a second operation on the 21st day. The rats were then randomly divided into four groups. Group I (n = 10) served as controls. Group II (n = 11) received letrozole (0.18 mg/kg, i.p.), group III (n = 10, i.p.) ETA (2.016 mg/kg, i.p.), and group IV (n = 10) INF (15.12 mg/kg, i.p.) for a second 21-day period. Endometriotic implant size along with peritoneal fluid VEGF level and immunoreactivity were determined before and after the treatment in each group. RESULTS: Endometriotic implant size reduced in all treatment groups. The effect of letrozole and ETA on implant size was similar but was significantly better than INF. Level of VEGF in peritoneal fluid did not change in any treatment group but post-treatment VEGF immunoreactivity was found significantly lower in the letrozole treated group. CONCLUSIONS: Letrozole and ETA caused a regression on the implant size in experimental endometriosis. The only group with decreased VEGF expression was letrozole.

Cystoscopic suture removal by Holmium-YAG laser after Burch procedure.

Burch colposuspension remains one of the successful operations performed for stress incontinence. Accidental suturing of the bladder wall during the procedure or subsequent erosion may lead to lower urinary tract symptoms. Diagnosis and management of these sutures indicate precise evaluation for which a 70 degree cystoscope is used. In selected cases, Holmium-YAG laser may enable us to manage long-standing, encrustated neglected sutures. Here we would like to report successful removal of intravesical sutures using the Holmium-YAG laser.

Prolonged usage of intravaginal clindamycin cream combined with ampicillin for the management of PPROM - a case report.

Prolonged PPROM may be catastrophic both for the mother and fetus due to ascending infections. The decision was expectant management in the setting of a spontaneous preterm premature rupture of membranes (PPROM) case and the prevention of chorioamnionitis was essential. We aimed to describe maternal and neonatal outcomes in expectant management of PPROM beginning from the 24(th) gestational week (GW) of pregnancy up to the 34(th) week under treatment with continuous usage of intravaginal clindamycin cream. We concluded that expectant active management of PPROM with antibiotics may be a suitable treatment option in carefully selected patients after receiving the patient's approval. Intravaginal clindamycin cream may be combined with systemic antibiotics (ampicillin and erythromycin) and may be a maintenance single drug for the prophylaxis of ascending vaginal infections.

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.

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.
