Seven episiotomy incisions are described in the literature, although only midline, mediolateral or lateral episiotomies are commonly used. Recent research has demonstrated variations in both site and direction of the incision, and differences between the angle of incision at the time of crowning of the fetal head and the angle of the scar once the wound has been repaired. We review this evidence and suggest that this variation may undermine the reliability of much published work. We suggest a standardised definition of each type of episiotomy to establish uniformity going forward, so that future studies are amenable to comparison and meta-analysis. © 2012 RCOG.

Objective To compare the de novo prolapse rate in the untreated vaginal compartments following conventional vaginal prolapse repair and tension-free vaginal mesh repair. Design Secondary analysis of a randomised controlled trial. Setting Thirteen centres in the Netherlands. Population Women with recurrent pelvic organ prolapse stage II or higher. Methods Random assignment to either conventional vaginal native tissue repair or vaginal mesh insertion. Main outcome measures Primary outcome: de novo pelvic organ prolapse stage II or higher in the untreated vaginal compartments at 12 months after surgery. Secondary outcomes: de novo pelvic organ prolapse at and beyond the hymen, de novo prolapse beyond the hymen and prolapse domain scores of the Urogenital Distress Inventory. Results At 12 months ten of 59 women (17%) in the conventional group versus 29 of 62 women (47%) in the mesh group were diagnosed with a de novo pelvic organ prolapse stage II or higher in the untreated compartment (P < 0.001, odds ratio 4.3, 95% confidence interval 1.9-10.0). Additional apical support to a mesh-augmented anterior repair significantly reduced the de novo prolapse rate. Women with a de novo prolapse in the mesh-treated group demonstrated significantly higher mean bother scores on the domain genital prolapse of the Urogenital Distress Inventory score (13.1 ± 24.2) compared with those without de novo prolapse (2.9 ± 13.9) (P = 0.03). Conclusion Mesh-augmented prolapse repair in only one vaginal compartment is associated with a higher de novo prolapse rate in the untreated compartments compared with conventional vaginal native tissue repair in women with recurrent pelvic organ prolapse. © 2012 RCOG.

Background: Legg-Calvé-Perthes disease is a pediatric disorder characterized by osteonecrosis of the proximal femoral epiphysis. The etiology probably involves successive vascular occlusions, in which hypercoagulable disorders may play a role. We evaluated the etiologic role of thrombophilia in Legg-Calvé-Perthes disease in a pediatric population. Methods: One hundred and sixty-nine consecutive patients who had been diagnosed with Legg-Calvé-Perthes disease at two centers in Rotterdam, the Netherlands, when they were between 1.5 and 13.5 years of age were identified between 2000 and 2003. The study also included two control groups: 474 subjects (16.3 to 73.1 years of age) from a population-based case-control study on the etiology of venous thrombosis as well as thirty-eight children (1.8 to 18.8 years of age) who were treated for asthma at one of the centers. We determined levels of protein C, protein S, factor VIII, and fibrinogen and tested for the factor V Leiden and prothrombin G20210A mutations. We calculated age and sex-adjusted odds ratios as measures of the relative risk of the development of Legg-Calvé-Perthes disease. Results: The incidence of Legg-Calvé-Perthes disease was increased in the presence of the factor V Leiden mutation (odds ratio, 3.3; 95% confidence interval, 1.6 to 6.7), in the presence of the prothrombin G20210A mutation (odds ratio, 2.6; 95% confidence interval, 1.0 to 6.3), in association with elevated levels of factor VIII (>150 IU/dL) (odds ratio, 7.5; 95% confidence interval, 2.2 to 25.2), and in association with protein S deficiency (<67 U/dL) (odds ratio, 2.8; 95% confidence interval, 0.7 to 10.8). Neither high levels of fibrinogen (>4.0 g/L) nor protein C deficiency (≤55 U/dL) had an apparent effect on the risk of Legg-Calvé-Perthes disease. (Odds ratios were adjusted for age and sex.) Overall, males had a 2.4 times higher risk of Legg-Calvé-Perthes disease developing than did females. The effect of the factor V Leiden mutation, high levels of fibrinogen, and increasing levels of factor VIII was stronger in males than in females. The risk of Legg-Calvé-Perthes disease increased with an increasing number of coagulation abnormalities in males but not in females. Conclusions: There appears to be a thrombotic component in the etiology of Legg-Calvé-Perthes disease. Clinical Relevance: The findings of this study contribute to the understanding of the etiology of Legg-Calvé- Perthes disease and may thus have implications for its prevention or treatment.

Rationale: It is unknown whether lactate monitoring aimed to decrease levels during initial treatment in critically ill patients improves outcome. Objectives: To assess the effect of lactate monitoring and resuscitation directed at decreasing lactate levels in intensive care unit (ICU) patients admitted with a lactate level of greater than or equal to 3.0 mEq/L. Methods: Patients were randomly allocated to two groups. In the lactate group, treatment was guided by lactate levels with the objective to decrease lactate by 20% or more per 2 hours for the initial 8 hours of ICU stay. In the control group, the treatment team had no knowledge of lactate levels (except for the admission value) during this period. The primary outcome measure was hospital mortality. Measurements and Main Results: The lactate group received more fluids and vasodilators. However, there were no significant differences in lactate levels between the groups. In the intention-to-treat population (348 patients), hospital mortality in the control group was 43.5% (77/177) compared with 33.9% (58/171) in the lactate group (P = 0.067). When adjusted for predefined risk factors, hospital mortality was lower in the lactate group (hazard ratio, 0.61; 95% confidence interval, 0.43-0.87; P = 0.006). In the lactate group, Sequential Organ Failure Assessment scores were lower between 9 and 72 hours, inotropes could be stopped earlier, and patients could be weaned from mechanical ventilation and discharged from the ICU earlier. Conclusions: In patients with hyperlactatemia on ICU admission, lactate-guided therapy significantly reduced hospital mortality when adjusting for predefined risk factors. As this was consistent with important secondary endpoints, this study suggests that initial lactate monitoring has clinical benefit.

OBJECTIVE: This study evaluates the effects of mechanical bowel preparation (MBP) on anastomosis below the peritoneal verge and questions the influence of MBP on anastomotic leakage in combination with a diverting ileostomy in lower colorectal surgery. SUMMARY BACKGROUND DATA: In a previous large multicenter randomized controlled trial MBP has shown to have no influence on the incidence of anastomotic leakage in overall colorectal surgery. The role of MBP in lower colorectal surgery with or without a diverting ileostomy remains unclear. METHODS: This study is a subgroup analysis of a prior multicenter (13 hospitals) randomized trial comparing clinical outcome of MBP versus no MBP. Primary end point was the occurrence of anastomotic leakage and secondary endpoints were septic complications and mortality. RESULTS: Total of 449 Patients underwent a low anterior resection with a primary anastomosis below the peritoneal verge. The incidence of anastomotic leakage was 7.6% for patients who received MBP and 6.6% for patients who did not. Significant risk factors for anastomotic leakage were the American Society of Anesthesiologists-classification (P = 0.005) and male gender (P = 0.007). Of total, 48 patients received a diverting ileostomy during initial surgery; 27 patients received MBP and 21 patients did not. There were no significant differences regarding septic complications and mortality between both groups. CONCLUSION: MBP has no influence on the incidence of anastomotic leakage in low colorectal surgery. Furthermore, omitting MBP in combination with a diverting ileostomy has no influence on the incidence of anastomotic leakage, septic complications, and mortality rate.

Background And Objectives: This study was performed to determine the minimum effective volume of ropivacaine 0.75% required to produce effective shoulder analgesia for an ultrasound (US)-guided block at the C7 root level with assessment of pulmonary function. Methods: Using the Dixon and Massey up-and-down method study design, 20 patients scheduled for elective open shoulder surgery under combined general anesthesia and continuous interscalene brachial plexus block were included. Initial volume of ropivacaine 0.75% was 6 mL; block success or failure determined a 1-mL decrease or increase for the subsequent patient, respectively. General anesthesia was standardized. A continuous infusion of ropivacaine 0.2% was started at a rate of 6 mL/hr at 2 hrs after completion of surgery. Ventilatory function was assessed using spirometry, and movement of the hemidiaphragm was assessed by US. Results: The minimum effective volume of local anesthetic in 50% and 95% of the patients was 2.9 mL (95% confidence interval, 2.4-3.5 mL) and 3.6 mL (95% confidence interval, 3.3-6.2 mL), respectively. Ventilatory function and hemidiaphragmatic movement was not reduced up to and including 2 hrs after completion of surgery, but 22 hrs after start of the continuous infusion of ropivacaine 0.2%, ventilatory function and hemidiaphragmatic movement were significantly reduced (P < 0.001). Conclusions: The minimum effective volume of local anesthetic for shoulder analgesia for a US-guided block at the C7 root level in 50% and 95% of the patients was 2.9 and 3.6 mL, respectively. Pulmonary function was unchanged until 2 hrs after completion surgery, but reduced 22 hrs after start of a continuous infusion of ropivacaine 0.2%.

Background Influenza virus infection is very common and a significant cause of morbidity and mortality in specific populations like pregnant women. Following the 2009 pandemic, several reports on the effects of influenza virus infection on maternal health and pregnancy outcome have been published. Also the safety and efficacy of antiviral treatment and vaccination of pregnant women have been studied. In this review, we have analyzed and summarized these data. Objective To provide information on the influence of influenza virus infection during pregnancy on maternal health and pregnancy outcome and on the effect of treatment and vaccination. Data sources We have searched Medline, Embase and the Cochrane Library. We used influenza, influenz pregnancy and pregnan∗ as search terms. Study selection In total, 294 reports were reviewed and judged according to the STROBE guidelines or CONSORT statement. In all, 100 studies, published between 1961 and 2015, were included. Results Compared to the general population, pregnant women are more often hospitalized and admitted to an intensive care unit due to influenza virus infection. For hospitalized patients, increased rates of preterm birth and fetal/neonatal death are reported. Early treatment with oseltamivir is associated with a reduced risk of severe disease. Vaccination of pregnant women is safe and reduces maternal and neonatal morbidity. Conclusions There is level 2b evidence that maternal health and pregnancy outcome can be severely affected by influenza virus infection. Antiviral treatment may diminish these effects and vaccination protects pregnant women and neonates from infection (level of evidence 2b and 1b, respectively). © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

Background Long-term comparisons of supervised exercise therapy (SET) and endovascular revascularization (ER) for patients with intermittent claudication are scarce. The long-term clinical effectiveness of SET and ER was assessed in patients from a randomized trial. Methods Consenting patients with intermittent claudication were assigned randomly to either SET or ER. Outcome measures on functional performance (pain-free and maximum walking distance, ankle: brachial pressure index), quality of life (QoL) and number of secondary interventions were measured at baseline and after approximately 7 years of follow-up. Repeated-measurement and Kaplan-Meier methods were used to analyse the data on an intention-to treat-basis. Results A total of 151 patients were randomized initially to either SET or ER. After 7 years, functional performance (P < 0·001) and QoL (P ≤ 0·005) had improved after both SET and ER. Long-term comparison showed no differences between the two treatments, except in the secondary intervention rate, which was significantly higher after SET (P = 0·001). Nevertheless, the total number of endovascular and surgical interventions (primary and secondary) remained higher after ER (P < 0·001). Conclusion In the longer term, SET-first or ER-first treatment strategies were equally effective in improving functional performance and QoL in patients with intermittent claudication. The substantially higher number of invasive interventions in the ER-first group supports a SET-first treatment strategy for intermittent claudication.

Objective To evaluate spontaneous vaginal delivery and complication rates after induction of labor with a transcervical Foley catheter in women with a previous cesarean delivery. Design Retrospective cohort study. Setting Secondary teaching hospital in the second largest city of the Netherlands. Population Women with a history of cesarean delivery (n = 208), undergoing induction of labor with a Foley catheter in a subsequent pregnancy. Material and methods The women who had induction of labor with a transcervical Foley catheter in the Ikazia Hospital, Rotterdam, between January 2003 and January 2012, were identified in a computerized database. Patient's records were checked for accuracy. Main outcome measures Vaginal delivery rate, cesarean section rate, uterine rupture and maternal and neonatal (infectious) morbidity. Results Of the women 60% had a spontaneous vaginal delivery and 11% were delivered by vacuum extraction. Uterine rupture occurred in one woman. Postpartum hemorrhage was the most common maternal complication (12%). Maternal intrapartum and postpartum infections occurred in 5% and 1%. Proven neonatal infection was found in 3% of the cases. Two perinatal deaths occurred (1%), of which one was related to uterine rupture. Conclusion Induction of labor with a transcervical Foley catheter is an effective method to achieve vaginal delivery in women with a previous cesarean delivery. There is a low risk of uterine rupture and maternal and neonatal (infectious) morbidity in this cohort. © 2013 Nordic Federation of Societies of Obstetrics and Gynecology.

Occurrence of breast cancer is a well-known long-term side effect of ionizing radiation (both diagnostic and therapeutic). The radiation-induced breast cancer risk increases with longer follow-up, higher radiation dose and younger age of exposure. The risk for breast cancer following irradiation for lymphomas is well known. Although data regarding the carcinogenic risk of adjuvant radiotherapy for a primary breast cancer are sparse, an increased risk is suggested with longer follow-up mainly when exposed at younger age. Particularly, patients with a BRCA1/. 2 mutation might be more sensitive for the deleterious effects of ionizing radiation due to an impaired capacity of repairing double strand DNA breaks. This might have consequences for the use of mammography in breast cancer screening, as well as the choice between breast conserving therapy including radiotherapy and mastectomy at primary breast cancer diagnosis in young BRCA1/. 2 mutation carriers. Good data regarding this topic, however, are scarce, mainly due to constraints in the design of performed studies. In this review, we will discuss the current literature on the association between ionizing radiation and developing breast cancer, with particular attention to patients with a BRCA1/. 2 mutation. © 2014 Elsevier Ltd.
