Nasal bone to nasal tip length ratio for describing nasal bone hypoplasia and predicting trisomy 21.

Introduction: Fetal nasal bone hypoplasia has been proven to be a strong marker for trisomy 21 during second trimester ultrasonography. Rather than evaluating the nasal bone hypoplasia according to the nomograms, it may be possible to evaluate it with a more practical and specific method. Material and methods: Retrospectively collected data were provided from the saved and stored patient data between 2012 and 2017. Nasal bone length and nasal tip length were measured and the ratio was calculated. The ratio ≤ 1/3 was defined as the threshold ratio for the definition of the marker. Nasal bone nasal tip length (NB/NL) ratio values were compared among groups with trisomy 21 and euploid fetuses. Results: A total of 59 fetuses had trisomy 21 and 2304 euploid fetuses were included in the study. The ratio of nasal bone to nasal tip length was 1/3 and below in 21/59 (35.5%) of fetuses with trisomy 21 whereas this ratio was 31/2304 (1.3%) in euploid fetuses. The difference was statistically significant (p < 0.001). Sensitivity, specificity, positive likelihood ratio and negative likelihood ratio of nasal bone/nasal tip ratio ≤ 1/3 were 35.5%, 98.6%, 26.4 and 0.6 for Down syndrome, respectively. Conclusions: This study suggested that the nasal bone to nasal tip length ratio may be a new promising and practical sonographic marker in the second trimester genetic sonography. Although its sensitivity is not high, it seems to be more practical and specific than the evaluation of fetal nasal bone length.

Chorionic villus sampling and preeclampsia & eclampsia: coincidence or not?

OBJECTIVES: The purpose of the study is to investigate potential association of chorionic villus sampling (CVS) with subsequent development of preeclampsia (PE) and eclampsia (E). STUDY DESIGN: The development of PE and E was compared between two groups as follows: 1- CVS group: women who underwent CVS (n = 228) and 2- Control group: maternal and gestational age matched women without invasive prenatal diagnostic procedure (n = 456). Main outcome measures were incidence of PE (mild, severe) and E. RESULTS: The incidence of PE and E was not significantly different between CVS and control groups. There was no significant difference regarding mild and severe PE development between the two groups. The incidence of early- and late-onset PE was similar in CVS and control groups. CONCLUSIONS: CVS does not appear to increase the risk of PE and E. The spontaneous elevation of trophoblastic load in the maternal circulation rather than the iatrogenic elevation through CVS may contribute to the development of PE and E.

Transabdominal versus transvaginal specimen extraction in mini-laparoscopic surgery.

AIM: The objective of this study was to present our experiences of tissue extraction via the transvaginal (TV) route after a mini-laparoscopic gynecological surgery and compare them with our transabdominal (TA) specimen extraction experiences. METHODS: This prospective randomized controlled study was conducted in a tertiary care center between July 2014 and February 2016. Fifty-eight women who were undergoing mini-laparoscopy for adnexal mass removal were randomized into two groups according to the surgical specimen removal by the TV route (n = 28) or the TA route (n = 30). The main outcome measures were the postoperative incisional pain, cosmetic outcomes and overall satisfaction rate. The secondary outcome measures were additional blood loss, additional operation duration and the need for morcellation. RESULTS: The TV group had significantly lower visual analog scale scores than the TA group at 6 and 24 h postoperatively. The morcellation needs were lower in the TV group than in the TA group. Three months after the surgery, the participants scored a higher rate of overall satisfaction in the cosmetic outcomes in the TV group than in the TA group. CONCLUSION: Tissue extraction through a posterior colpotomy after mini-laparoscopic surgery may be a feasible technique for improving cosmetic results, decreasing postoperative pain and decreasing the need for morcellation when compared to TA specimen retrieval.

Arcuate artery calcification on transvaginal sonography may predict coronary artery heart disease.

Atherosclerosis is a systematic disease affecting all arteries and is the most common cause of mortality. Our aim was to evaluate the predictive value of the presence of uterine arcuate artery calcification (AAC) for coronary heart disease (CHD) in women. Seventy women presenting with angina pectoris or a finding suggestive of cardiac ischaemia in non-invasive tests, scheduled for angiography between June 2014 and July 2015 were recruited in the study. One day before the coroner artery angiography, all of the patients were examined about the presence of AAC by transvaginal ultrasonography and were classified in the presence of CHD. CHD is classified as obstructive (obstruction >70%) or as non-obstructive (obstruction <70%) according to the severity of stenosis. The association of AAC is evaluated with the presence and severity of CHD that's diagnosed by angiography. CHD was present in 87.2% of women with positive for AAC and in 4.3% of who were negative for AAC (p = .001). AAC positive women were more likely to develop obstructive CHD than non-obstructive CHD (66.6% versus 30.9%, p = .001), respectively. Sensitivity and specificity of AAC for CHD were 97.6% and 78.5%, respectively. AAC detected by transvaginal ultrasound seems to have a strong association with both presences of CHD and the severity of disease. Impact statement What is already known on this subject? Atherosclerosis affecting all arteries is the primary cause of mortality and morbidity of coronary heart disease (CHD) (Lim et al. 2011). Uterine artery calcification and its association with atherosclerosis were first reported by Camiel et al. (1967). Ozdemir et al. (2016) found a correlation between carotid artery intima thickness and the presence of uterine arcuate artery calcification (AAC). What do the results of this study add? Very few studies have been performed in this area investigating the relationship of AAC and non-invasive predictors of atherosclerosis or the relationship between arterial calcifications and cardiovascular or systemic disease. Our study is the first to evaluate the correlation between AAC and CHD confirmed using coronary artery angiography at a high sensitivity rate (97.6%). What are the implications of these findings for clinical practice and/or further research? Our study presents an alternative, easy and non-invasive method for the prediction of subclinical CHD in clinical practice. From the view of a gynaecologist, cardiology consultation of patients with AAC detected by transvaginal ultrasonography during the routine gynaecologic examination may be useful and protective against serious cardiac problems. Thus, this study is of great importance in terms of predicting when the majority of CHD patients are asymptomatic or in the subclinical phase.

Prophylactic McCall Culdoplasty by a Vaginal Approach during Mini-Laparoscopic Hysterectomy.

BACKGROUND: In gynecological surgery, one particular area of concern after hysterectomy is the risk of developing an enterocele or vaginal apical prolapse. The aims of this study were to evaluate the safety and efficacy of prophylactic McCall culdoplasty (MC) performed during mini-total laparoscopic hysterectomy (mini-TLH), as well as to compare the differences in apical support, total vaginal length (TVL), and sexual function at one and two years postoperatively. METHODS: Data were retrospectively reviewed for all women who underwent mini-TLH and mini-TLH + MC at a tertiary care center between August 2012 and January 2016 were from the hospital database. There were 18 women who underwent mini-TLH + MC and were considered as the study group, while 20 women who were treated with mini-TLH were considered as the control group. The primary outcome measures were the differences in apical support and TVL and impact on sexual function. RESULTS: After mini-TLH + MC, the apical vaginal support difference was improved by 2.2 cm. The mean difference in C point was 1.03 cm in the mini-TLH group, which was not significant at two years after the operation. The vaginal vault descent at two years after operation was more prominent in the mini-TLH group than the mini-TLH + MC groups. Apical support changes at two years after the operation were more prominent in the mini-TLH group (0.5 ± 0.6 cm) than the mini-TLH + MC group (1.9 ± 1.2 cm). CONCLUSION: Prophylactic MC by a vaginal approach during mini-TLH is safe, satisfactory, and efficient for apical support without severe morbidity.

Fetal cardiac examination can affect patients' preference on invasive tests: A new data on maternal anxiety indicated karyotyping.

BACKGROUND: Prenatal screening for aneuploidies has seen great changes over the last 2 decades. But there is still no non-invasive diagnostic test. Therefore, prenatal invasive procedures are still being routinely performed due to maternal anxiety. The association of cardiac anomalies and abnormal findings with aneuploidies has been known for a long time. This prospective study was done to evaluate abnormal fetal cardiac examination (FCE) findings on patients undergoing diagnostic invasive procedures due to maternal anxiety and to assess the predictive value of abnormal cardiac findings on abnormal karyotype. MATERIALS AND METHODS: Patients who underwent prenatal diagnostic invasive tests due to maternal anxiety indication between March 2013 and September 2016 were included in this study. FCE was performed in the study group immediately prior to invasive tests. Findings of fetal cardiac examination are classified as normal, major-minor cardiac anomalies and soft markers. Fetal karyotypes were compared among groups depending on cardiac findings. RESULTS: One hundred eighty-two invasive procedures were performed because of maternal anxiety during this period. There were 29 abnormal findings detected on FCE. A total of 7 abnormal karyotypes were detected. FCE was abnormal in 5 of the abnormal karyotypes (71.4%). The presence of a major cardiac anomaly was most predictive for abnormal karyotype (LR+: 96,67, LR-: 0,34). No association was detected between the presence of minor cardiac anomalies and abnormal karyotype. Normal FCE appeared to be a good predictive factor for normal karyotype (LR-: 0.20). CONCLUSIONS: This is the first study evaluating the power of early fetal cardiac examination findings on fetal aneuploidies. This study suggested that the application of fetal cardiac examination findings to genetic counseling for screening aneuploidies may be efficient on patients' preference about invasive tests. Due to the small number of abnormal findings and karyotypes detected (not the large study group), further studies on large study groups are needed to confirm these results.

In utero Partial Exchange Transfusion Combined with in utero Blood Transfusion for Prenatal Management of Twin Anemia-Polycythemia Sequence.

Monochorionic twin pregnancies are at risk of unique complications due to placental sharing and vascular connections between placental territories assigned for each twin. Twin anemia-polycythemia sequence (TAPS) is an infrequent but potentially dangerous complication of abnormal placental vascular connections. TAPS occurs due to very-small-caliber (< 1 mm) abnormal placental vascular connections which lead to chronic anemia in the donor twin and polycythemia in the recipient twin. TAPS may occur spontaneously or following fetoscopic laser photocoagulation of communicating placental vessels for twin-twin transfusion syndrome. One of the hallmarks of TAPS is the absence of polyhydramnios and oligohydramnios. The postnatal diagnosis is based on significant hemoglobin discrepancy between the twins. Middle cerebral artery peak systolic velocity Doppler ultrasound allows for the prenatal diagnosis of TAPS. The optimal prenatal treatment and intervention timing has not been established. Here, we report 3 spontaneous TAPS cases diagnosed and managed in the prenatal period with a combination of in utero blood transfusion for the anemic twin (donor) and in utero partial exchange transfusion for the polycythemic twin (recipient). These cases contribute to the limited outcome data of this underutilized method for the management of TAPS.

Decline in ovarian reserve may be an undiagnosed reason for unexplained infertility: a cohort study.

INTRODUCTION: Unexplained infertility refers to the absence of a definable cause for a couple's failure to achieve pregnancy. Reproductive aging plays a role in pathogenesis of unexplained infertility. We investigated the results of ovarian reserve tests in unexplained infertility. MATERIAL AND METHODS: The patients were divided into two groups: unexplained infertility (n = 148) and male factor infertility (n = 112). Follicle-stimulating hormone, estradiol, inhibin b levels and anti-Müllerian hormone levels were evaluated. Antral follicle count and ovarian volume measurements were performed. RESULTS: The demographic variables were comparable. Follicle-stimulating hormone levels were higher in the unexplained infertility group than the male factor infertility group, although this difference did not reach statistical significance (p = 0.071). Estradiol levels, inhibin b concentrations and ovarian volume showed no difference between groups. However, antral follicle count was significantly lower in the unexplained infertility group than the male factor infertility group (p = 0.023). The median anti-Müllerian hormone concentrations were significantly lower in the unexplained infertility group 1.42 (0.4-6.2) than in the male factor infertility group (2.04 (0.64-8.2); p = 0.001). CONCLUSIONS: Although anti-Müllerian hormone values and antral follicle count were higher than the low thresholds, a statistically significant decline of ovarian reserve in the unexplained infertility group was found in the present study. This might be an undiagnosed reason for unexplained infertility.

Hysteroscopic evaluation of tubal peristaltic dysfunction in unexplained infertility.

It has been realised that rhythmic peristalsis of the ostia and tubes can be observed during hysteroscopy. The aim of this study was to examine the presence of tubal peristaltic dysfunction in unexplained infertility (UI). Hysteroscopy was performed in 35 women with UI and in 37 healthy fertile women. Bilateral tubal peristalses were assessed hysteroscopically by the observation of methylene blue injection and its transport to the Fallopian tubes. Tubal patency was evaluated with laparoscopic chromopertubation. Two women in control group (6.67%) and eight women in UI group (30.77%) had no tubal peristalsis, at least one tube with normal tubal patency. The difference was statistically significant (p = .019). Tubal peristaltic dysfunction may be a hidden cause of subfertility in women with bilateral patent Fallopian tubes. There is a definite need for larger trials to identify tubal peristaltic dysfunction as a cause of UI. Impact statement What is already known on this subject? Unexplained infertility has no identified pathophysiologic basis. It has been realised that rhythmic peristalsis of the ostia and tubes can be observed during hysteroscopy. What do the results of this study add? Tubal peristaltic dysfunction was detected in two tubes (3.70%) in a control group and nine tubes (19.57%) in women with unexplained infertility, when the tubes were patent. The difference was statistically significant (p = .012). What are the implications of these findings for clinical practice and/or further research? In cases of bilateral patent Fallopian tubes such as in unexplained infertility, tubal peristaltic dysfunction may be a hidden additional cause of subfertility.

Is the management of Rh-Rh incompatibility with noninvasive fetal Rh genotyping for targeted prophylaxis cost-effective in the Turkish population?

Background/aim: The aim of this study was to assess unnecessary immunization rates and compare the cost-effectiveness of targeted prophylaxis with fetal Rh genotyping with that of traditional management of Rh-Rh incompatibility in a virtual economic model. Materials and methods: This retrospective data analysis was conducted at two tertiary centers between 2011 and 2015. The data of 1135 pregnant women were analyzed. The main outcome measure was to determine the unnecessary immunization rate among the whole Rh-Rh incompatibility group. The second outcome measure was to compare the cost-effectiveness of universal immunization with that of targeted prophylaxis with fetal Rh genotyping in a virtual economic model. Results: Average cost per patient was found as $259.20 with universal prophylaxis and the total cost was $177,344, whereas if targeted prophylaxis had been applied to these patients the total cost would have been $263,392 and cost per patient would have been $385. Universal prophylaxis was more cost-effective than targeted prophylaxis in terms of both total cost and cost per patient (P < 0.0001). Conclusion: Unless the cost of noninvasive fetal Rh genotyping is reduced, a universal approach of anti-D immune globulin prophylaxis is more cost-effective than noninvasive determination of fetal Rh genotyping with targeted prophylaxis.

Conventional Chromosome Analysis of Fetuses with Central Nervous System Anomalies and Associated Anomalies: Is Anything Changed?

Central nervous system (CNS) abnormalities are often isolated but can accompany various genetic syndromes. In this study, we evaluated conventional karyotype results and associated findings of fetuses that were diagnosed with CNS abnormalities. Cases included in the study were diagnosed with fetal CNS anomalies and underwent conventional karyotyping. Conventional karyotype results of subjects were compared with karyotype results of fetal karyotyped patients as a result of maternal anxiety in a two-year period. In this period, 69 patients were diagnosed with fetal CNS anomalies and 64 of them underwent invasive fetal karyotyping. Of these, 32 patients had isolated CNS anomalies, while 32 were associated with other anomalies. There was no significant difference between karyotype results when compared with the control group (p = 0.76). Apart from some specific anomalies, the aneuploidy rate does not significantly differ between fetuses with CNS anomalies and the control group. Advanced genetic evaluation may provide additional diagnostic benefits, especially for this group.

Comparison of Three Different New Bipolar Energy Modalities and Classic Bipolar in Vivo for Tissue Thermal Spread.

OBJECTIVE: The aim of this study was to compare three different new bipolar energy modalities and classic bipolar in vivo for tissue thermal spread. MATERIAL AND METHOD: This prospective, randomized, single-blind study was conducted between Septemsber 2012 and July 2013. Eighteen patients aged 40-65 years undergoing hysterectomy and bilateral salpingectomy for benign etiology were included in the study. Before the hysterectomy operation began, it was marked nearly distal third cm started from uterine corn and proximal close third cm started from fimbrial bottoms by visualizing both fallopian tubes. The surgery was performed using one 5 mm applicator of PlasmaKinetics™, EnSeal®, LigaSure™ or classic bipolar energy modality. The time each device was used was standardized as the minimum time of the audible warning of the device for tissue impedance and as tissue vaporization on classic bipolar. Tissues were dyed by both H&E and Masson's Trichrome in the pathology laboratory. Thermal spread was compared. RESULTS: Evaluation of the damage on the uterine tubes by each device used revealed that LigaSure™ was associated with increased thermal injury compared to PlasmaKinetics™ (p=0.007). Apart from PlasmaKineticsTM (p=0.022), there was no statistically significant difference between the three devices in terms of thermal damage spread in the distal and proximal fallopian tubes. CONCLUSION: To reduce lateral thermal damage, Plasmakinetics™ may be preferable to Ligasure™ among the three different new bipolar energy modalities.

Diminished ovarian reserve: is it a neglected cause in the assessment of recurrent miscarriage? A cohort study.

OBJECTIVE: To study whether diminished ovarian reserve is associated with recurrent miscarriage. DESIGN: Cross-sectional clinical study. SETTING: Tertiary-care center. PATIENT(S): Women with history of recurrent miscarriage (RM; n = 71) and sequentially selected age-matched fertile women who were seeking contraception (control; n = 70). INTERVENTION(S): Not applicable. MAIN OUTCOME MEASURES(S): Serum levels of FSH, LH, E2, and antimüllerian hormone (AMH); FSH/LH ratio; ovarian volumes; and antral follicle count (AFC). RESULT(S): The levels of FSH were 8.6 ± 3.7 U/L in the RM group and 7.1 ± 3.9 U/L in the control group; this difference was statistically significant. The levels of AMH were significantly lower in the RM group than in the control group (2.9 ± 1.7 ng/mL vs. 3.6 ± 1.7 ng/mL). The percentage of women with levels of FSH ≥11 U/L was significantly higher in the RM group than in the control group (18.3% vs. 4.3%). In the RM group, the percentage of women with levels of AMH ≤1 ng/mL was significantly higher than in the control group (19.7% vs. 5.7%). CONCLUSION(S): Recurrent miscarriage may be associated with diminished ovarian reserve. Larger prospective randomized controlled trials are warranted to better determine the predictive potential of ovarian reserve markers in recurrent miscarriage.

Lipoleiomyoma of the uterus and primary ovarian leiomyoma in a postmenopausal woman: two rare entities in the same individual.

Uterine lipoleiomyomas are rare benign tumours that are composed of various mixtures of smooth muscle and mature fat tissue. Leiomyomas, which arise primarily in the ovary, are extremely rare tumours that account for 0.5-1% of all benign ovarian tumours. To the best of our knowledge, we present the first case of an ovarian leiomyoma coexisting with a uterine lipoleiomyoma in the postmenopausal period. A 59-year-old, gravida 4, para 3, postmenopausal woman exhibited pelvic discomfort and increased frequency of micturition. A pelvic examination revealed a solid, tender mass on the left side that could not be clearly separated from the uterus. She underwent a laparotomy with an initial diagnosis of a left ovarian mass. She had previously undergone a total abdominal hysterectomy and bilateral salpingo-oophorectomy. A histopathological examination revealed a uterine lipoleiomyoma, composed of variable amounts of smooth muscle cells and mature adipocytes and a right ovarian leiomyoma composed of interlacing bundles and fascicles of spindle cells. The coexistence of these two rare entities in the same individual may represent a common pathway as a stimulating agent. This case may help to clarify the pathogenesis of these lesions.

Comparative evaluation of the risk of malignancy index scoring systems (1-4) used in differential diagnosis of adnexal masses.

BACKGROUND: To determine the cut-off values of the preoperative risk of malignancy index (RMI) used in differentiating benign or malignant adnexal masses and to determine their significance in differential diagnosis by comparison of different systems. MATERIALS AND METHODS: 191 operated women were assessed retrospectively. RMI of 1, 2, 3 and 4; cut-off values for an effective benign or malignant differentiation together with sensitivity, specificity, negative and positive predictive values were calculated. RESULTS: Cut-off value for RMI 1 was found to be 250; there was significant (p<0.001) compatibility at this level with sensitivity of 60%, positive predictive value (PPV) of 75%, specificity of 93%, negative predictive value (NPV) of 88% and an overall compliance rate of 85%. When RMI 2 and 3 was obtained with a cut-off value of 200, there was significant (p<0.001) compatibility at this level for RMI 2 with sensitivity of 67%, PPV of 67%, specificity of 89%, NPV of 89%, histopathologic correlation of 84% while RMI 3 had significant (p<0.001) compatibility at the same level with sensitivity of 63%, PPV of 69%, specificity of 91%, NPV of 88% and a histopathologic correlation of 84%. Significant (p<0.001) compatibility for RMI 4 with a sensitivity of 67%, PPV of 73%, specificity of 92%, NPV of 89% and a histopathologic correlation of 86% was obtained at the cut-off level 400. CONCLUSIONS: RMI have a significant predictability in differentiating benign and malignant adnexal masses, thus can effectively be used in clinical practice.

Ultra-short term clomiphene citrate in high responder women with polycystic ovary syndrome: a case series.

OBJECTIVE: To evaluate a new trial of short-term clomiphene citrate (CC) in high responder women with polycystic ovary syndrome (PCOS). STUDY DESIGN: This case series was conducted in the infertility outpatient clinics of two centres. Ovulation induction was performed with CC 50-100mg a day in six high-responder women with PCOS who had a history of cancellation of treatment because of ≥3 mature follicles between March 2010 and June 2013. Induction was initiated on the third day of their cycles and the duration of induction was only two days. Demographic data of the patients, number of mature follicles on hCG day, ovulation rate, luteal phase length, pregnancy rate, and type of pregnancy were recorded. All data were analysed by SPSS packet programme (SPSS, 17.0, SPSS Inc., Chicago, IL, USA). RESULT(S): The median number of mature follicles and duration of the follicular phase were 1.3 (1-2) and 11.9 (11-14) days, respectively. The ovulation rate was 80% (12/15) and pregnancy rate per cycle was 26.6%. CONCLUSION(S): If this hypothesis is supported by large prospective randomised controlled studies, ultra-short term ovulation induction with CC may provide an alternative approach for high-responder women with PCOS who have a history of treatment cycle cancellations.

Ineffectual Medical Treatment of Cesarean Scar Ectopic Pregnancy With Systemic Methotrexate: A Report of Two Cases.

The implantation of a pregnancy within the scar of a previous cesarean section is known as a "cesarean scar pregnancy." Its incidence was reported to be 6.1%. However, with the increasing rates of cesarean sections, the incidence is expected to rise. A variety of conservative and surgical treatment modalities have been proposed for the management of cesarean scar pregnancy; however, there are no optimal universal treatment guidelines because of its rarity. Treatment should be tailored to the individual patient. It is obvious that more scar pregnancies will be seen in the future and therefore a set of criteria for the choice of various modes of management should be developed. Here, we present 2 cases of cesarean scar pregnancies treated with a local injection of potassium chloride after the failure of methotrexate administration.

Vascular reactivity in the experimental, simvastatin-treated diabetes with endothelial dysfunction.

BACKGROUND: The aim of this study was to evaluate the effect of simvastatin therapy on general characteristics of diabetes and vascular reactivity in the 14 week-old streptozotosin-diabetic rats. METHODS: Twenty-four Sprague-Dawley male rats were divided into four groups as following: control, control-statin, diabetes and diabetes-statin. RESULTS: We observed that hyperglycemia and weight-loss observed in diabetic rats were partially treated with simvastatin, but were still different from the control group. After thapsigargin, the endothel-mediated acetylcholine releasing responses were decreased; the releasing response in diabetes-statin group differed from the diabetic group. DISCUSSION: Simvastatin treatment in diabetic rats, in addition to the treatment of diabetic dislipidemia, has also partially treated the endothel-mediated releasing response in diabetes. We observed that thapsigargin reduces the response of the aortic rings to the current substance (Fig. 5, Ref. 15).
