Introduction and hypothesis: Midurethral slings (MUS) are the gold standard primary procedure for the surgical treatment of stress urinary incontinence (SUI). There is no robust evidence on the success with MUS in the treatment of recurrent SUI. Our objective was to evaluate the effectiveness and complications of MUS in women with recurrent SUI by systematic review and meta-analysis of the literature. Methods: A systematic literature search was carried out (up to August 2011) using relevant search terms in MEDLINE, EMBASE, CENTRAL and Google Scholar. Relevant randomised controlled trials (RCT) and prospective studies were selected and then analysed by two independent reviewers. Meta-analysis of cure stated in prospective cohort studies was performed with a random effects model using Stata 8. Results: There was 1 randomised trial and 11 good quality prospective studies included in this systematic review. The overall subjective cure rate per meta-analysis of prospective cohort studies following MUS for recurrent SUI after any previous surgery was found to be 78.5 % [95 % confidence interval (CI) 69-88] at the follow-up of 29.72±29.49 months. The subjective cure rate following MUS after previous failed MUS was 73.3 % (95 % CI 55-97) at the follow-up of 15.7± 7.7 months. Conclusions: The studies report good cure rates of SUI after MUS surgery following previous incontinence surgery (62-100 %). There seems to be a lower cure rate with trans-obturator compared to the retropubic tape for recurrent SUI after previous surgery. © The International Urogynecological Association 2012.

Background Urodynamics is widely used in the investigation of urinary incontinence. The existing evidence questions its add-on value in improving the outcome of surgical treatment for stress urinary incontinence (SUI). Objectives To compare the surgical outcomes in women with SUI or stress-predominant mixed urinary incontinence (MUI) based on urodynamic diagnoses compared with diagnoses based on office evaluation without urodynamics. Search strategy We searched Cochrane, MedLine, Embase, CINAHL, LILACS, metaRegister of Controlled Trials (mRCT) and Google Scholar databases from inception until March 2013. Selection criteria We included randomised controlled trials (RCTs) comparing surgical outcomes in women investigated by urodynamics and women who had office evaluation only. Data collection and analysis Two independent reviewers (S.R. and P.L.) extracted the data and analysed it using review manager (revman) 5.2 software. Main results Of the 388 articles identified, only four RCTs met our criteria. The data from one study are as yet unpublished. In the other three RCTs, the women with SUI or stress-predominant MUI were randomised either to office evaluation and urodynamics (n = 388) or to office evaluation only (n = 387). There was no statistical difference in the risk ratio (RR) of subjective cure in the two groups (RR 1.02, 95%CI 0.90-1.15, P = 0.79, I2 = 45%), objective cure (RR 1.01, 95%CI 0.93-1.11, P = 0.28, I2 = 20%) or complications such as voiding dysfunction (RR 1.54, 95%CI 0.61-3.89, P = 0.27, I2 = 18%) or urinary urgency (RR 0.80, 95%CI 0.28-2.3, P = 0.19, I2 = 40%). Authors' conclusions In women undergoing primary surgery for SUI or stress-predominant MUI without voiding difficulties, urodynamics does not improve outcomes - as long as the women undergo careful office evaluation. © 2014 Royal College of Obstetricians and Gynaecologists.

Background: Screening for critical congenital heart defects in newborn babies can aid in early recognition, with the prospect of improved outcome. We assessed the performance of pulse oximetry as a screening method for the detection of critical congenital heart defects in asymptomatic newborn babies. Methods: In this systematic review, we searched Medline (1951-2011), Embase (1974-2011), Cochrane Library (2011), and Scisearch (1974-2011) for relevant citations with no language restriction. We selected studies that assessed the accuracy of pulse oximetry for the detection of critical congenital heart defects in asymptomatic newborn babies. Two reviewers selected studies that met the predefined criteria for population, tests, and outcomes. We calculated sensitivity, specificity, and corresponding 95% CIs for individual studies. A hierarchical receiver operating characteristic curve was fitted to generate summary estimates of sensitivity and specificity with a random effects model. Findings: We screened 552 studies and identified 13 eligible studies with data for 229 421 newborn babies. The overall sensitivity of pulse oximetry for detection of critical congenital heart defects was 76·5% (95% CI 67·7-83·5). The specificity was 99·9% (99·7- 99·9), with a false-positive rate of 0·14% (0·06- 0·33). The false-positive rate for detection of critical congenital heart defects was particularly low when newborn pulse oximetry was done after 24 h from birth than when it was done before 24 h (0·05% [0·02- 0·12] vs 0·50 [0·29-0·86]; p=0·0017). Interpretation: Pulse oximetry is highly specific for detection of critical congenital heart defects with moderate sensitivity, that meets criteria for universal screening.

Objectives: (i) To evaluate the impact of routine early pulse oximetry screening on the rate of unexpected neonatal unit (NNU) admissions and the need for echocardiography. (ii) To review the outcomes of babies admitted as a result of a positive pulse oximetry screening test. Design: Retrospective review over a 40-month period. Setting: Level 3 NNU. Patients: All babies admitted as a result of positive pulse oximetry screening. Main outcome measures: Indication for admission, clinical diagnosis and management were collated. Results: 3552 babies were admitted during the study period. Of these, 1651 were unexpected admissions and 208/1651 (12.6%) were as a result of positive pulse oximetry screening. 165/208 babies (79%) had a significant clinical condition which required further intervention including 17 with congenital heart defect (CHD) (nine critical), 55 with pneumonia, 30 with sepsis and 12 with pulmonary hypertension. No baby died or collapsed on the postnatal ward during the study period. 61/208 babies (29%) had echocardiography and CHD was detected in 28%. Conclusions: Routine use of pulse oximetry screening identifies babies with CHD and other illnesses, which, if not identified early could potentially lead to postnatal collapse. It does not appear to overload clinical services, resulting in appropriate admission in the majority and a modest increase in the number of echocardiograms performed.

Introduction and hypothesis Mixed urinary incontinence (MUI) is a coexistence of stress (SUI) and urgency urinary incontinence (UUI). There is conflicting evidence on the effectiveness of midurethral slings (MUS) in this condition. The objective of this study is to evaluate the effectiveness of MUS in women with MUI by systematic review of the literature. Methods Systematic literature search was carried (June 2010) using relevant search terms in Medline, EMBASE, CENTRAL and Google Scholar. Relevant randomised controlled trials (RCT) and prospective studies were selected and then analysed by two independent reviewers. Meta-analysis was performed with random effects model using STATA 8. Results There were six randomised trials and seven prospective studies with average to good quality included in this systematic review. There was heterogeneity in outcomes reported. The overall subjective cure from seven prospective nonrandomised studies that included patients with symptomatic± urodynamically proven MUI was found to be 56.4% (95% confidence interval 45.7-69.6%) at 34.9±22.9 months follow-up. The overall cure of urgency and UUI component was 30-85%at a follow-up of few months up to 5 years.Most of the studies described that this cure does not persist over the time. The cure rate of SUI following MUS varies from85%to 97%. On meta-analysis of five RCTs which included women with MUI symptoms, the odds of overall subjective cure with TVT versus transobturator tapes are similar at 6-33 months follow-up (OR, 0.9; 95% CI, 0.63-1.27). This was true when a subgroup analysis was performed on women with MUI who were negative for DO on UDS (OR, 1.21; 95% CI, 0.7-2.08) Conclusions There is evidence of persistent and good cure of stress component following MUS in women with MUI. The cure of the urge component is variable but less than stress component. Methodologically sound RCTs of retropubic and transobturator tapes with long-term follow-up are needed specifically for women with urodynamically proven and symptomatic mixed incontinence. © The International Urogynecological Association 2011.
