Predictors of severity in primary postpartum hemorrhage

PURPOSE

To identify risk factors and etiologies leading to severe primary postpartum hemorrhage (PPH) in women with PPH.

METHODS

Women who experienced PPH within the first 24 h after delivery over a 3-year period were retrospectively evaluated. Patients were divided into two groups on the basis of severe PPH (n = 125) or non-severe PPH (n = 411). Risk factors and etiologies for severe PPH were explored using univariate and multivariate logistic regression analyses.

RESULTS

PPH and severe PPH complicated 2.1 and 0.49 % of all deliveries, respectively. Previous cesarean delivery (OR = 3.15, 95 % CI = 1.02-10.3; p = 0.001), prolonged labor (OR = 3.62, 95 % CI = 3.21-4.03; p < 0.001), oxytocin augmentation (OR = 3.32, 95 % CI 2.05-5.93; p < 0.001) and emergency cesarean delivery (OR = 4.75, 95 % CI 1.32-12.96; p < 0.001) were the factors independently associated with severe PPH. Etiologies significantly associated with severe PPH are uterine atony (OR = 2.72, 95 % CI 1.64-4.55; p < 0.001) and abnormal placentation (OR = 3.05, 95 % CI 1.56-6.27; p = 0.006).

CONCLUSION

Previous cesarean delivery, prolonged labor, oxytocin augmentation and emergency cesarean delivery are strongest predictors of severe blood loss in women with PPH. In addition, uterine atony and abnormal placentation are the etiologies significantly associated with severe PPH.

High first-trimester neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios are indicators for early diagnosis of preeclampsia

OBJECTIVES

The aim of our study is to determine whether first-trimester neutrophil-to-lymphocyte ratio (NLR) and plate-let-to-lymphocyte ratio (PLR) would be useful as new predictors of subsequent preeclampsia.

MATERIAL AND METHODS

Medical records of women with preeclampsia and healthy controls from a tertiary referral center were retrospectively evaluated. The two groups were compared in terms of clinical characteristics and first-trimester levels of hemoglobin, leukocyte, neutrophil, lymphocyte, platelet, NLR and PLR. Receiver operating characteristic curve (ROC) analysis was performed to identify the optimal NLR and PLR levels predicting preeclampsia.

RESULTS

Neutrophil (p < 0.001), platelet (p < 0.001), NLR (p < 0.001) and PLR (p < 0.001) levels were significantly elevated, whereas hemoglobin concentration (p = 0.003) was significantly lower in the group with preeclampsia as compared to the control group. On multivariate regression analysis, NLR (OR 1.43; 95% CI 1.21-1.76; p = 0.005) and PLR (OR 1.38; 95% CI 1.15-1.63; p = 0.008) were the most powerful predictive variables. The area under the ROC was 0.716 and 0.705 for NLR and PLR, respectively. The cut-off values of NLR ≥ 3.08 and PLR ≥ 126.8 predicted preeclampsia with the sensitivity of 74.6% and 71.8% and specificity of 70.1% and 72.4%, respectively.

CONCLUSIONS

High NLR and PLR during the first trimester are independent predictors of subsequent preeclampsia.

Lymphovascular space invasion and cervical stromal invasion are independent risk factors for nodal metastasis in endometrioid endometrial cancer

AIMS

The purpose of this study was to investigate the potential roles of pathological variables in the prediction of nodal metastasis in women with endometrioid endometrial cancer (EC).

MATERIALS AND METHODS

Women who underwent surgery for endometrioid EC between 1995 and 2012 were retrospectively reviewed. Those who underwent prior neoadjuvant chemotherapy or radiotherapy and inadequate lymphadenectomy as well as those with nonendometrioid histology, synchronous cancers, International Federation of Gynecology and Obstetrics stage IV disease, gross uterine serosal and/or gross adnexal involvement were excluded. Lymph node dissemination was defined as occurring in the following circumstances: (i) when nodal metastasis with pelvic and/or para-aortic (P/PA) lymph node dissection (LND) was performed or (ii) when there was recurrence in the P/PA lymph nodes after a negative LND or when LND was not performed. Univariate and multivariate logistic regression models were used to identify the pathological predictors of lymphatic dissemination.

RESULTS

A total of 827 women with endometrioid EC were assessed; 516 (62.4%) of whom underwent P/PA LND and 205 (24.8%) underwent P LND. Sixty-seven (13%) women in the P/PA LND group and 5 (2.4%) in the P LND group had positive lymph nodes. Multivariate analysis confirmed cervical stromal invasion (OR 4.04, 95% CI 2.02-8.07 (P < 0.001)) and lymphovascular space invasion (LVSI) (OR 110.18, 95% CI 38.43-315.87 (P < 0.001)) as independent predictors of lymphatic dissemination.

CONCLUSION

Cervical stromal invasion and LVSI are highly associated with LN metastasis. These markers may serve as a surrogate for nodal metastasis.

Benefits of short-term structured exercise in non-overweight women with polycystic ovary syndrome: a prospective randomized controlled study

[Purpose] The short-term effects of structured exercise on the anthropometric, cardiovascular, and metabolic parameters of non-overweight women diagnosed with polycystic ovary syndrome were evaluated. [Subjects and Methods] Thirty women with a diagnosis of polycystic ovary syndrome were prospectively randomized to either a control group (n=16) or a training group (n=14) for a period of 8 weeks. Anthropometric, cardiovascular, and metabolic parameters and hormone levels were measured and compared before and after the intervention. [Results] Waist and hip measurements (anthropometric parameters); diastolic blood pressure; respiratory rate (cardiovascular parameters); levels of low-density lipoprotein cholesterol, total cholesterol, fasting glucose, and fasting insulin; and the homeostasis model assessment of insulin resistance index (metabolic parameters) were significantly lower in the training group after 8 weeks of exercise compared to the baseline values. After exercise, the training group had significantly higher oxygen consumption and high-density lipoprotein levels and significantly shorter menstrual cycle intervals. The corresponding values for controls did not significantly differ between the start and end of the 8-week experiment. [Conclusion] Short-term regular exercise programs can lead to improvements in anthropometric, cardiovascular, and metabolic parameters of non-overweight women with polycystic ovary syndrome.

Impact of interpregnancy interval on the subsequent risk of adverse perinatal outcomes

AIM

The aim of this study was to investigate the impact of interpregnancy interval as a risk factor on multiple adverse perinatal outcomes.

MATERIAL AND METHODS

Interpregnancy intervals and confounding factors were determined for healthy pregnancies (controls [n = 357]) and for pregnancies complicated by adverse perinatal outcomes. Interpregnancy interval was categorized as <6, 6-11, 12-17, 18-23, 24-35 and ≥36 months. Adverse outcomes included spontaneous labor leading to preterm birth (n = 265), preterm premature rupture of membranes (n = 245), pre-eclampsia (n = 286), gestational diabetes (n = 302), abnormal placentation (n = 154), anemia (n = 314), congenital anomalies (n = 459), post-partum hemorrhage (n = 326) and small for gestational age (n = 168). Multivariate logistic regression analysis was performed to assess the association of each outcome with the interpregnancy interval categories.

RESULTS

Spontaneous labor leading to preterm birth (odds ratio [OR], 1.86; 95% confidence interval [CI], 1.13-1.97), preterm premature rupture of membranes (OR, 1.69; 95%CI, 1.28-2.39), congenital anomalies (OR, 1.38; 95%CI, 1.09-1.76) and small for gestational age (OR, 1.68; 95%CI, 1.14-2.34) were significantly associated with intervals of <6 months. Among congenital anomalies, short interpregnancy interval represents an increased risk for cardiac defects (OR, 1.55; 95%CI, 1.09-5.46), neural tube defects (OR, 2.06; 95%CI, 1.32-7.64) and central nervous system anomalies (OR, 1.45; 95%CI, 1.12-3.65).

CONCLUSION

Short interpregnancy interval is an independent risk factor for adverse perinatal outcomes.

Assessment of the effect of pelvic floor exercises on pelvic floor muscle strength using ultrasonography in patients with urinary incontinence: a prospective randomized controlled trial

[Purpose] The aim of this study was to evaluate whether the effect of pelvic floor exercises on pelvic floor muscle strength could be detected via ultrasonography in patients with urinary incontinence. [Subjects and Methods] Of 282 incontinent patients, 116 participated in the study and were randomly divided into a pelvic floor muscle training (n=65) group or control group (n=51). The pelvic floor muscle training group was given pelvic floor exercise training for 12 weeks. Both groups were evaluated at the beginning of the study and after 12 weeks. Abdominal ultrasonography measurements in transverse and longitudinal planes, the PERFECT scheme, perineometric evaluation, the stop test, the stress test, and the pad test were used to assess pelvic floor muscle strength in all cases. [Results] After training, the PERFECT, perineometry and transabdominal ultrasonography measurements were found to be significantly improved, and the stop test and pad test results were significantly decreased in the pelvic floor muscle training group, whereas no difference was observed in the control group. There was a positive correlation between the PERFECT force measurement scale and ultrasonography force measurement scale before and after the intervention in the control and pelvic floor muscle training groups (r=0.632 and r=0.642, respectively). [Conclusion] Ultrasonography can be used as a noninvasive method to identify the change in pelvic floor muscle strength with exercise training.

Lymphovascular space invasion and positive pelvic lymph nodes are independent risk factors for para-aortic nodal metastasis in endometrioid endometrial cancer

OBJECTIVE

Para-aortic lymph node dissemination in endometrioid endometrial cancer is uncommon, and systematic para-aortic lymph node dissection increases morbidity. The purpose of this study was to identify a subgroup of endometrioid endometrial cancer patients who did not require para-aortic lymphadenectomy.

STUDY DESIGN

All patients who had undergone surgery for endometrioid endometrial cancer between 1 January 1995 and 31 December 2012 were retrospectively reviewed. Patients with higher risk factors for nodal metastasis and inadequate lymphadenectomy were excluded. Para-aortic lymph node dissemination was defined as nodal metastasis when pelvic and para-aortic lymph node dissection was performed, when para-aortic lymph node recurrence occurred after negative para-aortic lymph node dissection or when para-aortic lymph node dissection was not performed. Multivariate logistic regression models were used to identify the pathological features as predictors for para-aortic lymphatic dissemination.

RESULTS

A total of 827 patients were assessed, 516 (62.4%) of whom underwent pelvic and para-aortic lymph node dissection. Sixty-seven (13%) patients (37 with only pelvic, 26 with pelvic and para-aortic, and 4 with only para-aortic metastasis) had positive lymph nodes in the pelvic and para-aortic lymph node dissection group. Multivariate analysis confirmed positive pelvic nodes (odds ratio 20.58; p<0.001) and lymphovascular space invasion (odds ratio 8.10; p=0.022) as independent predictors of para-aortic lymphatic dissemination. When these two factors were absent (in 83% of patients), the predicted probability of para-aortic lymph node metastasis was 0.1%.

CONCLUSION

Positive pelvic nodes and lymphovascular space invasion are highly associated with para-aortic lymph node metastasis. These markers may be useful for identifying those patients who require para-aortic lymph node dissection.

Identification of preterm birth in women with threatened preterm labour between 34 and 37 weeks of gestation

The aim of this study was to assess whether serum markers would be useful as a new predictor of preterm birth in patients with spontaneous, late preterm labour. Patients diagnosed with late preterm labour were divided into preterm delivery (229 patients) and term delivery (178 patients) groups. The two groups were compared in terms of clinical characteristics and levels of serum markers (leukocyte subtypes, platelet, C-reactive protein [CRP], neutrophil to lymphocyte ratio [NLR] and platelet to lymphocyte ratio [PLR]), which were obtained at admission. The levels of leukocyte (p < .001), neutrophil (p < .001), CRP (p = .001), NLR (p < .001) and PLR (p = .003) were significantly higher, whereas lymphocytes (p = .012) were significantly lower in the preterm delivery group, compared to the term delivery group. On multivariate regression analysis, NLR positive was the most powerful predictive variable (OR = 1.41; 95%CI: 1.32-1.51; p = .005). NLR had the highest area under curve (0.711; 95%CI 0.662-0.760) in predicting preterm birth and a NLR >6.2 had the highest sensitivity (65.1%) and specificity (62.5%). High NLR at admission is an independent predictor of preterm birth in patients with spontaneous, late preterm labour. Impact statement What is already known on this subject: Preterm birth accounts for 5-12% of all births, and is a major factor associated with perinatal morbidity and mortality worldwide. However, more than 70% of preterm births occur at late preterm between 34^0/7 and 36^6/7 weeks of gestation. The central role of systemic and subclinical infections in preterm labour is well documented. Intrauterine infection leading to delivery can be measured by using a variety of laboratory parameters. What do the results of this study add: Neutrophil to lymphocyte ratio is an inexpensive, easily interpretable and promising haematologic parameter that is widely available. This study explored the association of high neutrophil to lymphocyte ratio with the risk of preterm birth in women with preterm labour between 34 and 37 weeks of gestation. What are the implications of these findings for clinical practice and/or further research: Neutrophil to lymphocyte ratio could be used in combination with existing markers to improve detection rates of preterm birth. Concomitant use of markers could be more powerful than measuring any of the individual markers alone.

Prognostic Value of Fetal Thymus Size in Intrauterine Growth Restriction

OBJECTIVES

Our aim was to evaluate the size of the fetal thymus by sonography in pregnancies with intrauterine growth restriction (IUGR) and to search for a possible relationship between a small fetal thymus and adverse perinatal outcomes.

METHODS

The transverse diameter of the fetal thymus was prospectively measured in 150 healthy and 143 IUGR fetuses between 24 and 40 weeks' gestation. The fetuses with IUGR were further divided according to normal or abnormal Doppler assessment of the umbilical and middle cerebral arteries and ductus venosus. Measurements were compared with reference ranges from controls. To determine which perinatal outcomes were independently associated with a small fetal thymus, a multivariate logistic regression analysis was performed.

RESULTS

Thymus size was significantly lower in IUGR fetuses compared to controls (P < .05). Among IUGR fetuses, thymus size was significantly smaller in IUGR fetuses with abnormal Doppler flow compared to normal flow (P < .05). A small thymus in IUGR fetuses was independently associated with early delivery (odds ratio [OR], 1.24; 95% confidence interval [CI], 1.05-1.49; P= .023), respiratory distress syndrome (OR, 1.36; 95% CI, 1.09-1.78; P= .005), early neonatal sepsis (OR, 1.65; 95% CI, 1.11-2.42; P= .001), and a longer stay in the neonatal intensive care unit (OR, 1.33; 95% CI, 1.08-1.71; P = .017).

CONCLUSIONS

Intrauterine growth restriction is associated with fetal thymic involution, and a small fetal thymus is an early indicator of adverse perinatal outcomes in pregnancies complicated by IUGR.

Prognostic Significance of Retroperitoneal Lymphadenectomy, Preoperative Neutrophil Lymphocyte Ratio and Platelet Lymphocyte Ratio in Primary Fallopian Tube Carcinoma: A Multicenter Study

Purpose

The purpose of this study is to evaluate the prognostic role of preoperative neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) and the need for para-aortic lymphadectomy in patients with primary fallopian tube carcinoma (PFTC).

Materials and Methods

Ninety-one patients with a diagnosis of PFTC were identified through the gynecologic oncology service database of six academic centers. Clinicopathological, surgical, and complete blood count data were collected.

Results

In univariate analysis, advanced stage, suboptimal surgery, and NLR > 2.7 were significant prognostic factors for progression-free survival, whereas in multivariate analysis, only advanced stage and suboptimal surgery were significant. In addition, in univariate analysis, cancer antigen 125 ≥ 35 U/mL, ascites, advanced stage, suboptimal surgery, NLR > 2.7, PLR > 233.3, platelet count ≥ 400,000 cells/mm³, staging type, and histological subtype were significant prognostic factors for overall survival (OS); however, in multivariate analysis, only advanced stage, suboptimal surgery, NLR > 2.7, and staging type were significant. Inclusion of pelvic and para-aortic lymphadenectomy in surgery showed significant association with longer OS, with a mean and median OS of 42.0 months and 35.5 months (range, 22 to 78 months), respectively, vs. 33.5 months and 27.5 months (range, 14 to 76 months), respectively, for patients who underwent surgery without para-aortic lymphadenectomy (hazard ratio, 3.1; 95% confidence interval, 1.4 to 5.7; p=0.002).

Conclusion

NLR (in both univariate and multivariate analysis) and PLR (only in univariate analysis) were prognostic factors in PFTC. NLR and PLR are inexpensive and easy tests to perform. In addition, patients with PFTC who underwent bilateral pelvic and para-aortic lymphadenectomy had longer OS.

The Turkish version of the pregnancy physical activity questionnaire: cross-cultural adaptation, reliability, and validity

[Purpose] The aim of this study was to translate the Pregnancy Physical Activity Questionnaire, adapt it for use with Turkish subjects and determine its reliability and validity. [Subjects and Methods] The Pregnancy Physical Activity Questionnaire was translated into Turkish and administered twice at 7–14-day intervals to pregnant women to assess the test-retest reliability. Cronbach’s α was used for internal consistency, and the inter-rater correlation coefficient was used to calculate the test-retest reliability. The Turkish Short Form 36 Health Survey (SF-36) and the International Physical Activity Questionnaire were used to estimate validity. [Results] The internal consistency during the first and third trimesters of pregnancy was excellent, with Cronbach’s α values of 0.93 and 0.95, respectively. The mean interval between the two assessments was 11.1 ± 2.1 days. The correlation coefficient between the total activity measured by the Turkish version of the Pregnancy Physical Activity Questionnaire and the International Physical Activity Questionnaire estimates of the total metabolic equivalent were fair to poor during the first, second, and third trimesters of pregnancy (r = 0.17, r = 0.17, r = 0.21, respectively). The Turkish version of the Pregnancy Physical Activity Questionnaire showed fair correlations with the Short Form 36 Health Survey physical component score (r = −0.30) and mental component score (r = −0.37) for the first trimester of pregnancy. [Conclusion] The Turkish version of the Pregnancy Physical Activity Questionnaire was found to be reliable and valid for assessing a pregnant woman’s physical activity.

Stage-III and -IV endometrial cancer: A single oncology centre review of 104 cases

The objective of this study was to evaluate the clinicopathological characteristics, treatment and prognosis of advanced endometrial cancer (EC). Patients who underwent surgery for advanced EC between January 1995 and December 2012 were retrospectively reviewed. Patients with missing data, concurrent cancers or uterine sarcomas and those who did not undergo surgery were excluded. The effects of clinicopathological factors on progression-free survival (PFS) and overall survival (OS) were analyzed. A total of 104 patients were included. Most presented with endometrioid histology (74%) and stage-III disease (87.5%), and 76.9% underwent optimal cytoreduction. A multivariate analysis confirmed that lymphovascular space invasion (LVSI) is an independent poor prognostic factor for PFS [odds ratio (OR): 21.37, p = 0.005] and OS [OR: 8.09, p = 0.044]. Suboptimal cytoreduction is another independent poor prognostic factor for PFS [OR: 5.68, p < 0.001]. Our study demonstrated that LVSI and optimal cytoreduction are the most significant factors affecting the survival of advanced EC patients.

Analysis of endometrial carcinoma in young women at a high-volume cancer center

OBJECTIVE

To investigate the clinicopathological characteristics, treatment, survival, and prognosis of endometrial cancer in women aged ≤40 years.

METHODS

Women who underwent surgery for endometrial cancer at a single high-volume cancer center between January 1995 and December 2014 were retrospectively reviewed. Women aged >40, patients with missing data, and those who did not undergo surgical staging were excluded. Univariate and multivariate regression models were used to identify the risk factors for overall survival and progression-free survival.

RESULTS

A total of 40 patients with endometrial cancer were assessed. The median age at diagnosis was 38 (range, 21-40) years, and most of the uterine tumors found were early-stage (85%), low-grade (67.5%), and endometrioid carcinomas (97.5%). The median serum cancer antigen 125 level was 10.9 IU/mL (range, 3-1284 IU/mL). Optimal cytoreductive surgery was achieved in 35 patients (87.5%). All patients underwent total abdominal hysterectomy, and 97.5% of the patients underwent hysterectomy plus bilateral salpingo-oophorectomy. Among the total group of 40 patients, 21 (52.5%) underwent pelvic and para-aortic lymph node dissection, and 15 (37.5%) underwent only pelvic lymph node dissection. Multivariate analysis confirmed that a cancer antigen 125 level ≥35 was the only independent prognostic factor for both progression-free survival (hazard ratio, 22.997; 95% confidence interval, 1.783-296.536; p = 0.016) and overall survival (hazard ratio, 22.541; 95% confidence interval, 1.75-290.364; p = 0,017).

CONCLUSIONS

Our study demonstrated that a cancer antigen 125 level ≥ 35 is the only independent prognostic factor for both progression-free survival and overall survival in patients aged ≤40 years with endometrial cancer.

Is mucinous adenocarcinoma of the endometrium a risk factor for lymph node involvement? A multicenter case-control study

PURPOSE

The purpose of this multicenter case-control study was to compare the demographic and clinical characteristics of patients with mucinous adenocarcinoma of the endometrium (MAE) and endometrioid endometrial carcinoma (EEC).

METHODS

A retrospective review of two cancer registry databases in Turkey was conducted to identify patients diagnosed with MAE between January 1996 and December 2012. Each patient was matched with a control EEC patient by age and tumor grade. Cases and controls were compared in terms of known risk factors for lymph node metastasis, disease-free survival (DFS), and overall survival (OS).

RESULTS

The analysis included 112 patients with MAE and 112 with EEC. No significant difference in baseline characteristics was evident between the two groups. Lymphovascular space invasion, deep myometrial invasion, cervical involvement, and tumor diameter did not differ significantly between the mucinous and endometrioid cases. Multivariate analysis confirmed that only mucinous histology (OR 2.2, 95 % CI 1.1-4.5; P = 0.02) was an independent predictor of lymph node involvement. Although the median DFS and OS tended to be better in the endometrioid group, the differences were not statistically significant. Routine appendectomy was performed in 52 (46.2 %) patients with MAE. No mucinous tumor of the appendix was identified.

CONCLUSION

Routine appendectomy is not necessary when the appendix is grossly normal at the time of surgery for MAE. Although the DFS and OS of EEC and MAE patients were similar, the risk of nodal metastasis in MAE patients was greater than that in ECC patients, and we thus suggest to perform retroperitoneal lymphadenectomy (both pelvic and para-aortic) for patients with MAE during the initial operation.

Optimal cytoreduction, depth of myometrial invasion, and age are independent prognostic factors for survival in women with uterine papillary serous and clear cell carcinomas

OBJECTIVE

The purpose of this study was to investigate the clinicopathological characteristics, treatment methods, and prognostic factors in women with uterine papillary serous carcinoma (UPSC) and uterine clear-cell carcinoma (UCCC).

STUDY DESIGN

All patients who had undergone surgery for UPCS and UCCC between January 1995 and December 2012 were retrospectively reviewed. Patients with missing data, who did not undergo surgical staging and patients with mixed tumor histology were excluded. Multivariate regression models were used to identify the risk factors for overall survival (OS) and progression-free survival (PFS).

RESULTS

A total of 49 UPSC and 22 UCCC women were included. The majority of the patients were at stage I [IA, 22 (31%) and IB, 18 (25.4%)]. Stages II, III, and IV were identified in 9 (12.7%), 13 (18.3%), and 9 (12.7%) of cases, respectively. Optimal cytoreduction was achieved in 71.8% of cases. Recurrences occurred in 16 patients (22.5%). The 5-year OS rates were 67% for UPSC; 76% for UCCC; 68% for both histology, respectively. Multivariate analysis pointed out that age>67 years (odds ratio (OR): 3.85, p = 0.009 and OR: 3.35, p = 0.014), >50% myometrial invasion (MI) (OR: 2.87, p = 0.037 and OR: 2.46, p = 0.046) and optimal cytoreduction (OR: 3.26, p = 0.006 and OR: 2.77, p = 0.015) were the independent prognostic factors for both PFS and OS.

CONCLUSIONS

Our study demonstrated that optimal cytoreduction, >50% MI, and age >67 years are the most significant factors affecting survival in women with UPSC and UCCC.

Effect of antenatal betamethasone administration on Doppler velocimetry of fetal and uteroplacental vessels: a prospective study

OBJECTIVES

To examine the effect of antenatal betamethasone administration on Doppler parameters of fetal and uteroplacental circulation.

METHODS

Seventy-six singleton pregnancies that received betamethasone therapy were prospectively evaluated. Doppler measurements of pulsatility indices (PI) in fetal umbilical artery (UA), middle cerebral artery (MCA), ductus venosus and maternal uterine arteries were performed before (0 h) and 24, 48, 72 and 96 h after the first dose of betamethasone. Women with positive end-diastolic flow (EDF) in UA and those with absent or reversed EDF in UA were evaluated separately.

RESULTS

Fifty-two women with EDF in UA and 24 women with absent or reversed flow in UA were examined. Administration of maternal betamethasone was followed by a significant decrease in the PI of the MCA at 24 h (P<0.05). Additionally, return of absent to positive, reversed to absent or from reversed to positive diastolic flow in UA was detected within 24 h in 19 (79.2%) fetuses with absent or reversed UA-EDF. All alterations were transient and maintained up to 72 h.

CONCLUSIONS

Antenatal administration of betamethasone is associated with significant but transient changes in the fetal blood flow. Hence, intensive surveillance of fetuses with Doppler ultrasonography is warranted following betamethasone therapy.

Umbilical stalk elevation technique for safer Veress needle insertion in obese patients: a case-control study

OBJECTIVE

The purpose of this retrospective study was to compare our umbilical stalk elevation (USE) technique with the classic Veress needle (VN) technique in obese patients.

STUDY DESIGN

The USE technique was performed on 40 patients. One control per case was randomly selected from among those undergoing the classic VN technique using a random number table. In USE technique, a 12 mm skin incision was created at the superior crease of the umbilical fold, and the underlying subcutaneous adipose tissue was bluntly dissected using the tip of a fine clamp until the umbilical stalk was isolated at the inferior and central part of the incision. Next, the umbilical stalk was covered and held by a towel clip, and the abdominal wall was elevated by upward traction. The VN was then inserted nearly perpendicular to the incision and turned toward the pelvis immediately after resistance to the needle had been lost. A post-hoc power analysis was performed.

RESULTS

The number of attempts was significantly lower in the USE laparoscopy group than in the classic laparoscopy group (1.2 ± 0.4 vs. 2.1 ± 0.7, respectively; P<0.001). The USE technique group had a slightly shorter abdominal entry time than did the classic technique group (328.52 ± 63.71 vs. 434.95 ± 124.10s; P<0.001). Six (7.5%) failed insufflations occurred in our study (5 patients in the classic group vs. 1 patient in the USE group (P=0.10).

CONCLUSION

Our novel USE technique can be an effective means of establishing pneumoperitoneum in obese patients undergoing gynecologic laparoscopic procedures.

Quantitative Evaluation of the Fetal Cerebellar Vermis Using the Median View on Two-Dimensional Ultrasound

Background

Evaluation of the cerebellum and vermis is one of the integral parts of the fetal cranial anomaly screening.

Objectives

The aim of this study was to create a nomogram for fetal vermis measurements between 17 and 30 gestational weeks.

Patients and Methods

This prospective study was conducted on 171 volunteer pregnant women between March 2013 and December 2014. Measurements of the fetal cerebellar vermis diameters in the sagittal plane were performed by two-dimensional transabdominal ultrasonography.

Results

Optimal median planes were obtained in 117 of the cases. Vermian diameters as a function of gestational age were expressed by regression equations and the correlation coefficients were found to be highly statistically significant (P < 0.001). The normal mean (± standard deviation) for each gestational week was also defined.

Conclusion

This study presents the normal range of the two-dimensional fetal vermian measurements between 17 and 30 gestational weeks. In the absence of a three-dimensional ultrasonography, two-dimensional ultrasonography could also be used confidently with more time and effort.

Comparison of adverse perinatal outcomes after single-needle and double-needle CVS techniques

OBJECTIVE

To determine the impact of the chorion villus sampling (CVS) technique on adverse perinatal outcomes.

METHODS

In this case-control study, 412 women who underwent CVS at 11-14 weeks of gestation and 231 women who did not undergo any invasive procedure were retrospectively evaluated. The women in the CVS group were further divided into two groups according to the use of single-needle technique (n=148) vs. double-needle technique (n=264). The adverse outcomes were compared between controls and the two CVS groups, and regression analysis was used to determine the significance of independent contribution.

RESULTS

The rate of preeclampsia for the control group was 2.2%, for the double-needle group was 3% and for the single-needle group was 8.1%. CVS with single-needle technique was found to be an independent and statistically significant risk factor for preeclampsia [odds ratio (OR)=2.1, 95% confidence interval (CI); 1.4-2.7, P=0.008].

CONCLUSION

The risk of preeclampsia after CVS appears to be increased with single-needle technique compared with double-needle technique.
