ABSTRACT

The objective was to assess the effects of prenatal yoga on heart rate variability (HRV) and cardio-respiratory synchronization, used as proxies of autonomic nervous system activity. Sixty-nine healthy pregnant women were included; 33 in a yoga group attending at least one 90-min yoga class weekly throughout pregnancy, and 36 controls not involved in formal pregnancy exercise programs. Measurements of the time domain (SDNN, standard deviation of regular R-R intervals, and RMSSD, square root of mean squared differences of successive R-R intervals) and frequency domain (ln(LF/HF), natural logarithm of low-frequency to high-frequency power) HRV indices, as well as cardio-respiratory synchronization indexes were performed once per trimester before and after yoga or 30-min moderate-intensity walk. A statistical comparison was performed using a three-way analysis of the variance (p < 0.05 significant). Both the time domain and frequency domain HRV indices showed significant shifts towards parasympathetic dominance following yoga when compared to the controls throughout pregnancy (p = 0.002 for SDNN, p < 0.001 for RMSSD, and p = 0.006 for ln(LF/HF), respectively). There was a statistically non-significant trend towards higher synchronization between respiratory frequency and heart rate following yoga vs. controls (p = 0.057). Regular prenatal yoga was associated with enhanced parasympathetic activation persisting throughout pregnancy.

ABSTRACT

Aim: To compare the perinatal outcome and delivery intervals after the induction of labour with the Prostin vaginal tablet versus the Propess vaginal system in pregnant women with term-PROM. Design: One centre paralleled randomised controlled trial with a computer-generated table to allocate treatments. Setting: University Medical Centre in Slovenia. Participants: A total of 205 singleton healthy pregnant women with term-PROM. Intervention: Induction of labour with the Propess vaginal system (intervention group) versus Prostin tablets (control group). Main outcomes: The rate of failed inductions, complications in labour, time intervals between the PROM, induction, the beginning of the active phase, and delivery. Results: A total of 104 patients received Prostin, and 101 patients received Propess. Induction failure rates in the Prostin and the Propess groups were 8/104 (7.7%) and 5/101 (5.0%), respectively (p = 0.80). Delivery abnormalities were uncommon and comparable across the groups. The rates of caesarean sections in the Prostin and Propess groups were 4/96 (4.2%) and 6/96 (6.3%), respectively. The delivery intervals were comparable across the groups. Conclusions: In term-PROM pregnancies, the Propess vaginal system is a safe and effective option for inducing labour.

ABSTRACT

BACKGROUND Scimitar syndrome (SCS) is a rare congenital cardiopulmonary malformation, characterized by anomalous pulmonary venous drainage from the right lung associated with aortopulmonary collateral arteries and pulmonary hypoplasia. The variant described in the case presented here, with total anomalous right pulmonary venous drainage into the superior and inferior vena cava, can be expected in 2% of patients with scimitar syndrome. To the best of our knowledge, the association between the variant of SCS and coarctation of aorta described in our patient has never been reported before in the literature. CASE REPORT A female newborn with a gestational age of 35 weeks presented with a rare combination of scimitar syndrome and aortic coarctation. The patient had a variant of SCS that included anomalous drainage of the right upper and lower pulmonary vein into the superior and inferior vena cava, respectively; relative right lung hypoplasia; and right lower lobe sequestration supplied by aortopulmonary collateral arteries that originated from the truncus coeliacus. The diagnosis was confirmed with computed tomography angiography after resection of the aortic coarctation with extended end-to-end anastomosis. Subsequently, interventional closure of the collateral artery supplying the right lower lobe was performed with an AMPLATZER™ Vascular Plug 4. The patient's clinical course was complicated by suspicious acute endocarditis and chylous pleural effusion. After a prolonged hospitalization, she was discharged in clinically stable condition. CONCLUSIONS The diagnosis of SCS should be considered when pulmonary hypertension persists after coarctation repair in a child with dextroposition of the heart and right lung hypoplasia. Successful treatment of this rare combination of conditions calls for teamwork by highly experienced specialists.

ABSTRACT

Nowadays, women want a more intimate and familiar atmosphere during labour, which results in increased planned home birth rates. Every woman has the autonomy to decide where she will give birth; however, it is important that she is informed of risks and advantages beforehand. Home births can be distinguished between planned and unplanned home births. Planned home births can be conducted by professional birth attendants (licensed midwives) or birth assistants (doulas, etc). The rates of Slovenian women who decided to deliver at home are increasing year by year. Researches on home births still present discordant data about home birth safety. Their findings have shown that the main advantage of home birth is a spontaneous birth without medical interventions, especially in multiparous low-risk women. The main disadvantage, however, is a higher risk for neonatal death, in particular on occurrence of complications requiring a transfer to hospital and surgical intervention. Global guidelines emphasize careful selection of candidates suitable for home birth, well-informed pregnant women, education of birth attendants, and strict formation of transfer indications.

ABSTRACT

The association between vitamin D deficiency and various adverse pregnancy outcomes has been extensively investigated in recent years. The pregnant woman is the only source of vitamin D for the foetus. The main sources of vitamin D for pregnant women are sunlight, fortified dairy products, oily fish and dietary supplements. Vitamin D deficiency during pregnancy has been associated with some adverse neonatal outcomes as well as an increased risk of late pregnancy complications. The outcomes of the published studies investigating preeclampsia and gestational diabetes mellitus vary with some large trials suggesting a potential positive effect of vitamin D supplementation during pregnancy on the decreased risk of these complications. Research also suggests a possible connection between lower vitamin D concentrations and increased risk of preterm labour. In our manuscript, we aim to review the existing literature regarding the prevalence of vitamin D deficiency during pregnancy, the factors associated with vitamin D deficiency, and possible pregnancy complications arising from it.

ABSTRACT

BACKGROUND: During pregnancy, fetal cells suitable for genetic testing can be obtained from amniotic fluid by amniocentesis (AC), placental tissue by chorionic villus sampling (CVS), or fetal blood. A major disadvantage of second trimester amniocentesis is that the results are available relatively late in pregnancy (after 16 weeks' gestation). Earlier alternatives are chorionic villus sampling (CVS) and early amniocentesis, which can be performed in the first trimester of pregnancy. OBJECTIVES: The objective of this review was to compare the safety and accuracy of all types of AC (i.e. early and late) and CVS (e.g. transabdominal, transcervical) for prenatal diagnosis. SEARCH METHODS: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (3 March 2017), ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP; 3 March 2017), and reference lists of retrieved studies. SELECTION CRITERIA: All randomised trials comparing AC and CVS by either transabdominal or transcervical route. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. The quality of the evidence was assessed using the GRADE approach. MAIN RESULTS: We included a total of 16 randomised studies, with a total of 33,555 women, 14 of which were deemed to be at low risk of bias. The number of women included in the trials ranged from 223 to 4606.Studies were categorized into six comparisons: 1. second trimester AC versus control; 2. early versus second trimester AC; 3. CVS versus second trimester AC; 4. CVS methods; 5. Early AC versus CVS; and 6. AC with or without ultrasound.One study compared second trimester AC with no AC (control) in a low risk population (women = 4606). Background pregnancy loss was around 2%. Second trimester AC compared to no testing increased total pregnancy loss by another 1%. The confidence intervals (CI) around this excess risk were relatively large (3.2% versus 2.3 %, average risk ratio (RR) 1.41, 95% CI 0.99 to 2.00; moderate-quality evidence). In the same study, spontaneous miscarriages were also higher (2.1% versus 1.3%; average RR 1.60, 95% CI 1.02 to 2.52; high-quality evidence). The number of congenital anomalies was similar in both groups (2.0% versus 2.2%, average RR 0.93, 95% CI 0.62 to 1.39; moderate-quality evidence).One study (women = 4334) found that early amniocentesis was not a safe early alternative compared to second trimester amniocentesis because of increased total pregnancy losses (7.6% versus 5.9%; average RR 1.29, 95% CI 1.03 to 1.61; high-quality evidence), spontaneous miscarriages (3.6% versus 2.5%, average RR 1.41, 95% CI 1.00 to 1.98; moderate-quality evidence), and a higher incidence of congential anomalies, including talipes (4.7% versus 2.7%; average RR 1.73, 95% CI 1.26 to 2.38; high-quality evidence).When pregnancy loss after CVS was compared with second trimester AC, there was a clinically significant heterogeneity in the size and direction of the effect depending on the technique used (transabdominal or transcervical), therefore, the results were not pooled. Only one study compared transabdominal CVS with second trimester AC (women = 2234). They found no clear difference between the two procedures in the total pregnancy loss (6.3% versus 7%; average RR 0.90, 95% CI 0.66 to 1.23, low-quality evidence), spontaneous miscarriages (3.0% versus 3.9%; average RR 0.77, 95% CI 0.49 to 1.21; low-quality evidence), and perinatal deaths (0.7% versus 0.6%; average RR 1.18, 95% CI 0.40 to 3.51; low-quality evidence). Transcervical CVS may carry a higher risk of pregnancy loss (14.5% versus 11.5%; average RR 1.40, 95% CI 1.09 to 1.81), but the results were quite heterogeneous.Five studies compared transabdominal and transcervical CVS (women = 7978). There were no clear differences between the two methods in pregnancy losses (average RR 1.16, 95% CI 0.81 to 1.65; very low-quality evidence), spontaneous miscarriages (average RR 1.68, 95% CI 0.79 to 3.58; very low-quality evidence), or anomalies (average RR 0.68, 95% CI 0.41 to 1.12; low-quality evidence). We downgraded the quality of the evidence to low due to heterogeneity between studies. Transcervical CVS may be more technically demanding than transabdominal CVS, with more failures to obtain sample (2.0% versus 1.1%; average RR 1.79, 95% CI 1.13 to 2.82, moderate-quality evidence).Overall, we found low-quality evidence for outcomes when early amniocentesis was compared to transabdominal CVS. Spontaneous miscarriage was the only outcome supported by moderate-quality evidence, resulting in more miscarriages after early AC compared with transabdominal CVS (2.3% versus 1.3%; average RR 1.73, 95% CI 1.15 to 2.60). There were no clear differences in pregnancy losses (average RR 1.15, 95% CI 0.86 to 1.54; low-quality evidence), or anomalies (average RR 1.14, 95% CI 0.57 to 2.30; very low-quality evidence).We found one study that examined AC with or without ultrasound, which evaluated a type of ultrasound-assisted procedure that is now considered obsolete. AUTHORS' CONCLUSIONS: Second trimester amniocentesis increased the risk of pregnancy loss, but it was not possible to quantify this increase precisely from only one study, carried out more than 30 years ago.Early amniocentesis was not as safe as second trimester amniocentesis, illustrated by increased pregnancy loss and congenital anomalies (talipes). Transcervical chorionic villus sampling compared with second trimester amniocentesis may be associated with a higher risk of pregnancy loss, but results were quite heterogeneous.Diagnostic accuracy of different methods could not be assessed adequately because of incomplete karyotype data in most studies.

ABSTRACT

OBJECTIVE: To analyze the vitamin D status of pregnant women in Slovenia and the factors influencing it. METHODS: The study was performed in Maribor University Medical Centre (location 46°N). Maternal serum 25-hydroxy-vitamin D (25(OH)D) in 4 groups of 100 pregnant women in 4 different seasons of the year was measured at the time of delivery. Data on life style, eating habits, sunbathing and intake of vitamin D supplements during pregnancy were obtained using a questionnaire. Information on maternal outcome was acquired from medical records. Duration of sunlight and average temperature in the month preceding delivery were calculated from meteorological data. RESULTS: The average maternal 25(OH)D concentration ranged from 28.5 ± 17.1 nmol/l in March to 54.8 ± 24.1 nmol/l in June (p < 0.001). Severe vitamin D deficiency, i.e. <25 nmol/l 25(OH)D was present in 23.6% of women overall. In multiple regression analysis supplements containing vitamin D (ß = 0.225, p < 0.001) and duration of intentional exposure to sunlight (ß = 0.192, p = 0.026) were associated with maternal 25(OH)D status. Significantly lower vitamin D levels were observed in women who had a cesarean section (t = 2.053, p = 0.041) and those with premature delivery (t = 2.296, p = 0.022). Vitamin D levels were not associated with the occurrence of gestational diabetes, gestational hypertension or infections during pregnancy. CONCLUSION: A high prevalence of vitamin D deficiency was detected at the end of pregnancy, especially in the months following autumn and winter and in women who did not take supplements containing vitamin D.

ABSTRACT

OBJECTIVE: While foreign research shows a high prevalence of vitamin D deficiency in pregnant women and consequently in neonates, we do not have any data on vitamin D concentration in these risk groups for Slovenia. We performed a prospective study to evaluate vitamin D concentration in pregnant women and neonates in Maribor region. STUDY DESIGN: We determined 25-hydroxy-vitamin D concentration from blood samples taken before delivery from 100 pregnant women who gave birth in Maribor University Clinical Centre in September and December 2013, respectively, and from the cord blood of their neonates. We collected data on nutrition and sun exposure during pregnancy. We calculated the vitamin D concentrations in pregnant women and neonates according to season of birth and use of nutrition supplements, determined the vitamin D levels in some pregnancy complications and checked the correlation of maternal and neonatal vitamin D concentrations. RESULTS: The average vitamin D concentration in the September group was 54.3±25.2nmol/L, and in the December group 33.3±18.6nmol/L (p<0.001). Optimal vitamin D concentration (>80nmol/L) was reached by 12.0% of pregnant women in September and by only 2.0% in December. Women who took nutrition supplements containing vitamin D during pregnancy had significantly higher vitamin D levels than those who did not (September 68.9±27.0nmol/L vs. 46.5±20.3nmol/L, p<0.001; December 38.7±17.9nmol/L vs. 30.2±18.4nmol/L, p=0.028). Neonates had higher average levels of vitamin D than their mothers but there was a good correlation between maternal and neonatal vitamin D values. CONCLUSION: Vitamin D deficiency is very common in pregnant women in Slovenia as well, especially in winter and in those women who do not take nutrition supplements containing vitamin D.

ABSTRACT

OBJECTIVE: Quantitative-fluorescence polymerase chain reaction (QF-PCR) was used to detect common fetal aneuploidies in pregnancies with increased (maternal age) or high risk (increased nuchal translucency, abnormal fetal ultrasonography, positive biochemical hormone test, or positive family history) for fetal aneuploidy. METHODS: The QF-PCR testing was performed on 642 prenatal samples (73.3% amniotic fluids, 26.7% chorionic villus). DNA from prenatal samples were analyzed using an in-house-developed QF-PCR method with 20 micro-satellite markers located on the chromosomes 13, 18, 21, X and Y. Karyotyping of the 392 samples was done and both results were compared. RESULTS: 634/642 samples were successfully analyzed. In 7.1% of 634 cases numerical chromosome abnormalities were detected. Results of QF-PCR and karyotyping were compared in 392 cases. In the group, with increased risk of fetal trisomy the specificity and sensitivity of QF-PCR method was 100%. Among cases with high risk for fetal aneuploidy, sensitivity was 100% (86.6%-100%); however, the specificity was lower, 91.1% to 100%, depending on the referral reason. CONCLUSIONS: In women, at advanced age QF-PCR can be used alone without karyotyping. In cases with higher risk, especially those with abnormal ultrasound findings, analysis performed only with QF-PCR is not a sufficient diagnostic method.

ABSTRACT

BACKGROUND: Currently, the techniques for amniocentesis and chorionic villus sampling (CVS) tend to be described in local and national guidelines, but certain aspects, including the choice of instruments, is predominantly based upon the operator's personal preference. A survey of practice in the specialist UK centres revealed a wide variation of practice; therefore, standardising any element of technique could potentially influence the safety of the procedure. OBJECTIVES: The objective of this review was to compare the safety and effectiveness of all techniques of performing both amniocentesis and CVS for prenatal diagnosis. SEARCH METHODS: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (11 April 2012). SELECTION CRITERIA: We included all randomised comparisons of different methods of performing amniocentesis after 15 weeks' gestation, or CVS (transabdominal or transvaginal) with each other or with no testing. We excluded quasi-randomised studies (e.g. alternate allocation). DATA COLLECTION AND ANALYSIS: Both review authors independently assessed for inclusion all the potential studies identified as a result of the search strategy. Both review authors independently assessed trial quality. Both review authors extracted data. Data were checked for accuracy. MAIN RESULTS: We included five randomised studies with total of 1049 women evaluating five different technique modifications during either amniocentesis (three studies) or CVS (two studies).For amniocentesis three interventions were evaluated - intramuscular progesterone, hexoprenaline and selecting high or low puncture sites for late 'blind' procedure - each intervention in a single small study. There was no conclusive evidence of benefit for any of them. The same applies for terbutaline tocolysis and use of continuous vacuum aspiration during CVS. AUTHORS' CONCLUSIONS: Overall, the quality of evidence summarised in this review is not of sufficient quality to change current clinical practice. In the absence of clear evidence, the operators should continue to use methods and technique modifications with which they are most familiar with.Any randomised trials of technique modifications that are performed to high standard with adequate safety outcomes and power to detect important clinical differences would be clearly welcome.

ABSTRACT

BACKGROUND: Besides risks of miscarriage, pregnant women undergoing amniocentesis or chorionic villus sampling (CVS) are also concerned about pain associated with these procedures. Currently, approaches to analgesia can be categorised in two broad categories - non-pharmacological and pharmacological agents. OBJECTIVES: To evaluate whether different methods of analgesia have any impact on pain reduction during amniocentesis or chorionic villus sampling (CVS). SEARCH METHODS: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 August 2011). SELECTION CRITERIA: All randomised trials comparing different method of analgesia for amniocentesis or CVS. We also include trials with quasi-randomised designs, but analyse and report their results separately. DATA COLLECTION AND ANALYSIS: Both review authors assessed eligibility and trial quality and performed data extraction. MAIN RESULTS: We included a total of five randomised studies (involving 805 women) evaluating different methods of analgesia for amniocentesis; there were no studies in women undergoing CVS.One RCT (N = 203) and one quasi-randomised study (N = 220) compared infiltrative local anaesthesia with no anaesthesia and found no statistical difference in experienced pain on the visual analogue scale (VAS) (mean differences (MD) -2.50 and 1.20; 95% confidence interval (CI) -6.98 to 1.98 and -2.67 to 5.07).One study (N = 200) compared light leg rubbing versus no intervention during amniocentesis and found no change in experienced anxiety (MD 0.2; 95% CI -0.63 to 1.03) or VAS pain score (MD 0.3; 95% CI -0.35 to 0.95) during amniocentesis.Another study with 62 patients did not find any benefit of using subfreezing temperature needle during amniocentesis in terms of decreased VAS pain score (MD -0.8; 95% CI -1.8 to 0.2). In addition, there was no difference between anticipated and actual pain (MD 0.4; 95% CI -0.82 to 1.62) (before/after comparison).There was also no difference in VAS pain scores in the study with 120 participants comparing lidocaine-prilocaine analgesic cream to placebo cream before amniocentesis (MD -0.6; 95% CI -1.44 to 0.24). AUTHORS' CONCLUSIONS: In general, women who undergo amniocentesis could be informed that pain during procedure is minor and that there is currently insufficient evidence to support the use of local anaesthetics, leg rubbing or subfreezing the needle for pain reduction during procedure.

ABSTRACT

BACKGROUND: Any screening program aiming to reassure pregnant women that their unborn baby is healthy will cause anxiety while waiting for the test results. OBJECTIVES: 1) To determine if revealing amniocentesis or chorionic villous sampling (CVS) results on a fixed date alters maternal anxiety during the waiting period, compared with a policy of revealing the result "when available" (i.e. variable date). 2) To evaluate whether issuing early results from a rapid molecular test alters maternal anxiety during the waiting period. 3) To evaluate whether different methods of communication (telephone, fax, email, face to face) have any impact on the parents' satisfaction and anxiety levels. SEARCH STRATEGY: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 August 2010). SELECTION CRITERIA: All published and unpublished randomised trials, in which methods of issuing prenatal test results are compared. DATA COLLECTION AND ANALYSIS: Two review authors (Faris Mujezinovic and Zarko Alfirevic) assessed eligibility and trial quality and performed data extraction. MAIN RESULTS: Two studies (involving 286 women) from amniocentesis (but none from CVS) compared the impact of communicating results of rapid testing with waiting for definitive karyotype. Unfortunately, it was not possible to perform pooled analysis because one study reported only median (interquartile range) data, presumably because the data were not normally distributed.One study reported a statistically significant reduction in the average anxiety during the waiting period for women who had had a rapid test compared with those who had not (mean difference (MD) -2.30, 95% confidence intervals (CI) -3.08 to - 1.52). The other study compared median (interquartile range) for the trait- and state-anxiety scores and found no difference between the two groups. AUTHORS' CONCLUSIONS: We found no conclusive evidence that, while waiting for the full karyotype following amniocentesis, issuing results from a rapid analysis reduces maternal anxiety. The limited evidence from the two trials included in this review does not help resolve the dilemma about whether full karyotyping should be abandoned in favour of limited rapid testing for women undergoing Down's syndrome screening. This choice will rest on clinical arguments and cost-effectiveness rather than impact on anxiety.There is also no evidence to support the view that issuing amniocentesis results as soon as they are available is more user friendly than using a pre-defined fixed date. Studies evaluating the effect of different strategies for disclosing results on women anxiety for CVS are needed.

ABSTRACT

OBJECTIVE: To evaluate the differences in number of harvested retroperitoneal pelvic lymph nodes by specific lymph node regions in respect to pelvic laterality. STUDY DESIGN: We extracted cases of early ovarian cancer (EOC) with lymphadenectomy from the medical database which were treated at our institution in the period between 1994 and 2008. Recommendations of FIGO and EGSOC (European Guidelines for Staging in Ovarian Cancer) for staging of ovarian malignancies were followed. Stage of the disease was established on the basis of intra-abdominal condition which we found during surgery and histopathologic status of retroperitoneal lymph nodes (LN). For each case and every LN group, we subtracted the number of dissected lymph nodes on the left side from the number of dissected lymph nodes on the right side of the pelvis. The result would represent the difference between number of removed LN on each side of the pelvis for specific LN group. A negative difference means that a greater number of LN was extracted from the left side and a positive difference that the greater number of LN was extracted from the right side of the pelvis. We used Wilcoxon signed-rank test for statistical analysis of differences. RESULTS: 48 cases with EOC underwent lymphadenectomy. In three cases, metastatic retroperitoneal pelvic lymph nodes were found. There were 79.1%, 50.0%, 45.8%, 93.8%, 52.1%, 60.4% and 70.8% of cases with left-right difference in number of removed lymph nodes in external iliac region, common iliac region, presacralic, above obturator nerve, under obturator nerve, lateral from the external ilac vessels and lateral from the common iliac vessels nodal group, respectively. The mean differences between left and right groups were in the range from 2 to 4 lymph nodes. There was no identifiable bias toward either side of the pelvis for any of the analyzed lymph node groups. CONCLUSION: There is a right and left prevalence of retrieved LN by individual LN regions in the pelvis that could be influenced by asymmetry in right-left pelvic LN distribution. However, we did not find any evidence that the observed imbalance is, on average, directed toward either side of the pelvis.

ABSTRACT

UNLABELLED: AIM AND BACKGROUND.:To determine whether left-right asymmetry was present in cases of early ovarian cancer and whether or not the difference between number of removed lymph nodes on both sides of the pelvis is associated with tumor laterality. METHODS AND STUDY DESIGN: We extracted from the medical data base cases of early ovarian cancer with lymphadenectomy who had been treated between 1994 and 2008. The sample was divided in three groups according to the left-right laterality of the tumor in the pelvis (bilateral, left sided, right sided). For each case, we subtracted the number of dissected lymph nodes on the left side from the number of dissected lymph nodes on the right side of the pelvis (N(Right side) - N(Left side)). We used one sample t test to determine whether the mean of differences for each group was different from zero. Results. We extracted 48 cases with early ovarian cancer who had undergone lymphadenectomy. The average number of dissected lymph nodes was 24 (SD, 12). In 3 cases, we confirmed the presence of lymph node metastasis (6.3%). In 2 of the upstaged cases, tumor and involved lymph nodes were on the right side of the pelvis. In the third case, the tumor was on the left side, whereas involved lymph nodes were on both sides of the pelvis. For bilateral tumors, tumors on the left, and those on the right side of the pelvis, the mean difference was -0.5 (95% CI, -9.9 to 8.9; t, -0.137; P = 0.90), 0.32 (95% CI, -3.8 to 4.5; t, 0.16; P = 0.87) and 3.5 (95% CI, 0.03 to 7.01; t, 2.09; P = 0.048), respectively. CONCLUSIONS: When the tumor was on the left or on both sides of the pelvis, there was no significant difference in the number of removed lymph nodes. In contrast, when the tumor was on the right side, the number of removed lymph nodes was significantly higher on the right hemipelvis than on the left hemipelvis.

ABSTRACT

OBJECTIVE: The mutant genotype GG of the CYP17A1 gene polymorphism has been linked to higher levels of serum estradiol and thus might be associated with steroid-hormone dependent tumors. We decided to assess an association of CYP17A1 polymorphism with uterine leiomyomas (ULM) and multiple ULM by conducting a meta-analysis and subgroup analysis. METHODS: We searched the HuGE Navigator and PubMed databases using the terms "leiomyoma" and "CYP17A1" for articles published by October 1, 2010. Our article in press was added. The selection criteria were (i) cases having ULM, (ii) controls showing no ULM from the same ethnic group, (iii) cases and controls not overlapping. The subgroup analysis included cases having multiple ULM, predisposing black women mostly present with multiple ULM. Pooled risk ratio was calculated using χ ^{2} statistic. RESULTS: Five papers fulfilled the selection criteria for meta-analysis and two papers for the subgroup analysis. The meta-analysis revealed no association of CYP17A1 polymorphism with all ULM. A high pooled risk ratio for multiple ULM was associated with the presence of mutant genotype GG (RR 3.25). CONCLUSION: CYP17A1 polymorphism may be associated with multiple ULM but not with all ULM. The future research might enable us to predict the course of the disease.

ABSTRACT

OBJECTIVE: To compile a systematic review of complications related to genetic amniocentesis and chorionic villus sampling (CVS) to provide benchmark data for counseling and performance assessment of individual operators. DATA SOURCES: We searched the MEDLINE database for articles published after January 1, 1995, that reported data for at least 100 women with singleton pregnancies with genetic amniocentesis after 14 weeks of pregnancy and reports of CVS carried out transabdominally between 10 and 14 weeks. METHODS OF STUDY SELECTION: For amniocentesis, 29 articles fulfilled search criteria. Sixteen studies fulfilled search criteria for CVS. TABULATION, INTEGRATION, AND RESULTS: After genetic amniocentesis, pooled pregnancy loss within 14 days was 0.6% (95% confidence interval [CI] 0.5-0.7), rising to 0.9% (95% CI 0.6-1.3) for pregnancy loss before 24 weeks and 1.9% (95% CI 1.4-2.5) for total pregnancy loss. Corresponding figures for CVS were 0.7%, 1.3%, and 2%. The data on multiple insertions showed large heterogeneity, ranging from 0.2% to 2.9% for amniocentesis (pooled risk 2.0%, 95% CI 0.9-3.6) and from 1.4% to 26.6% for CVS (pooled risk 7.8%, 95% CI 3.1-14.2). Only five amniocentesis studies provided controls, but none was matched for gestational age. Pooled relative risks for fetal loss before 28 weeks and total pregnancy loss were 1.46 (95% CI 0.86-2.49) and 1.25 (95% CI 1.02-1.53), respectively. CONCLUSION: Although the risks of pregnancy loss are relatively low, lack of adequate controls tends to underestimate the true added risk of prenatal invasive procedures.
