Assessment of resident competency in the performance of sonohysterography: does the level of training impact the accuracy?

OBJECTIVE: The objective of this study was to examine the true-positive rates by level of training of the operator and to determine whether the accuracy of the procedure differed by the level of education after formalized training. STUDY DESIGN: This was a retrospective analysis. The records of patients who underwent surgery for the indication of an abnormal saline sonohysterography were reviewed from January 2001 to April 2003 (n=73 patients). The nature of the saline sonohysterography abnormality, the intraoperative findings, and the level of training of the provider were recorded. Findings at saline sonohysterography were compared with findings at hysteroscopy or surgery. Statistical significance was determined by chi(2) test. RESULTS: The overall true-positive rate was 86.3% (63/73 patients). The true-positive rates for nurse practitioners, second- and fourth-year residents, and fellows were 84%, 80%, 90%, and 89%, respectively. There was no significant difference among providers (P=.96). CONCLUSION: The true-positive rates for saline hysterography were comparable among different provider levels.

Detection of fetal growth restriction in patients with chronic hypertension: is it feasible?

Objective: To determine the utility of sonographic estimated fetal weight (EFW) in diagnosing intrauterine growth restriction (IUGR, birth weight < 10% for gestational age) in patients with chronic hypertension. Methods: All pregnant patients with hypertension delivered during a 5-year period at three centers were identified retrospectively. Patients with gestational hypertension, pre-eclampsia, diabetes mellitus, fetal anomalies and absence of a sonographic examination within 3 weeks of delivery were excluded. Likelihood ratio (LR) and guidelines established by the Evidence-Based Medicine Working Group were used to determine whether sonographic EFW is a reliable diagnostic test to detect IUGR. Results: At the three centers, there were 264 patients with chronic hypertension (122, 77 and 65 at centers I, II and III, respectively). The incidence of IUGR ranged from 13% to 27% but was similar at the three locations (p = 0.064). The LR (with 95% confidence interval (CI)) of detecting IUGR was 4.4 (95% CI 2.5, 7.7), 2.3 (95% CI 1.4, 3.7) and 6.1 (95% CI 2.7, 13.7) at centers I, II and III, respectively. Based on the proportions of abnormal growth, we required 253 and 71 newborns with fetal growth restriction at centers I and II, respectively, to have narrow confidence intervals around the clinically important LR of 10. The extremely low incidence of IUGR at center III (13%) precluded the estimation of required sample size. Conclusion: Use of Evidence-Based Medicine Working Group guidelines indicates that sonographic EFW is slightly to moderately useful in detecting fetal growth restriction in patients with chronic hypertension.     

Results of in vitro fertilization in patients with endometriomas: is surgical removal beneficial?

OBJECTIVE: The purpose of this study was to investigate the effect of endometriomas on clinical pregnancy rates of in vitro fertilization-embryo transfer. STUDY DESIGN: Infertile patients with endometriosis who underwent in vitro fertilization-embryo transfer were divided into group 1 patients who had a history of ovarian endometriomas and group 2 patients who did not. The patients in group 1 were further divided into group 1A who had their endometriomas removed by laparoscopic ovarian cystectomy before the start of in vitro fertilization-embryo transfer and group 1B who underwent in vitro fertilization-embryo transfer with the presence of endometriomas. The clinical pregnancy rates of these groups were compared. RESULTS: Clinical pregnancy rates per transfer were similar in group 1 and group 2 (40% vs 47%; P =.38) and similar in patients in group 1A and group 1B (47% vs 34%; P =.28), although the direction was toward improved pregnancy rates in the groups of patients without endometriomas present at the time of in vitro fertilization stimulation. When patients >39 years of age were excluded, the overall pregnancy rate was higher in those patients who had no current endometriomas than in those patients who had endometriomas present at the time of stimulation (65% vs 39%; P =.05). For patients with unilateral endometriomas, similar numbers of mature oocytes were aspirated between the affected and unaffected ovaries. CONCLUSION: Although the history of endometriomas does not appear to affect in vitro fertilization-embryo transfer outcomes adversely, there may be a benefit in the removal of endometriomas before in vitro fertilization.     

Cesarean section: is pretransfusion testing for red cell alloantibodies necessary?

BACKGROUND: Routine pretransfusion testing for red cell alloantibodies (RBCab) in cesarean patients is standard practice in many obstetric centers. The objective of the present study was to evaluate the usefulness of this test. METHOD: A retrospective study was conducted using computerized registers to extract data on blood transfusions and the occurrence of RBCab in cesarean patients. RESULTS: A total of 4434 admissions for cesarean section were identified. Only 10 patients (0.23%) had clinically significant RBCab, which had not been previously detected. Blood transfusions were required in relation to 147 cesarean sections (3.3%). A number of preoperative conditions, traditionally believed to be risk factors for preoperative and postpartum hemorrhage, occurred more frequently in transfused patients than in nontransfused. The probability of a cesarean patient having a previously undetected clinically significant RBCab and receiving a blood transfusion during admission for delivery was estimated to be 9.0 x 10(-5) (1 in 11 050 cesarean sections). Analyses of the time relationships between cesarean sections and initiation of blood transfusions indicated that most often there would be enough time for postoperative antibody screening and/or cross matching if the routine pretransfusion testing was omitted. CONCLUSION: These findings suggest that routine pretransfusion testing in cesarean patients can be omitted.     

What is the role of lymphadenectomy in surgical management of patients with endometrial carcinoma?

The role of lymphadenectomy in the management of endometrial carcinoma remains controversial in gynecologic oncology. Comprehensive pelvic and paraaortic lymphadenectomy should be performed in patients with intermediate- and high-risk endometrial cancer.     

Endometriosis: what is the risk of hospital admission, readmission, and major surgical intervention?

STUDY OBJECTIVE: To describe trends in hospital utilization and surgical rates for endometriosis and to estimate the probability of hospital readmission over 4 years among women with early-stage disease. DESIGN: Population-based, retrospective cross-sectional and longitudinal analysis of 53,385 hospital admissions for same-day surgery or inpatient treatment of endometriosis from fiscal years 1994/95 through 2001/02 (Canadian Task Force classification III). SETTING: All hospital discharge records that listed endometriosis as the most-responsible diagnosis in the province of Ontario, Canada, from fiscal years 1994-1995 through 2001-2002. PATIENTS: Ontario female patients 15 years of age or older admitted to the hospital for treatment of endometriosis. INTERVENTIONS: Surgical treatments were classified as minor, intermediate, or major depending on the extent of the surgery. MEASUREMENTS AND MAIN RESULTS: Age-standardized annual discharge rates were calculated and trends in surgical treatment described. The records of 7993 women who received minor or intermediate surgery on their index hospital visit were linked, and the likelihood and predictors of readmission were calculated using survival analysis and logistic regression. During the observation period, the standardized discharge rates fell significantly from 172.9 per 100,000 women aged 15 to 70 to 137.1 per 100,000 (p<.05). Age-specific rates were highest for women aged 15 to 39 (approximately 200 per 100,000). The proportion of hospitalizations involving minor surgeries dropped (from 27% to 17%), and the proportion involving intermediate surgeries increased (from 40% to 53%). The likelihood of hospital readmission within 4 years for additional surgical treatment was 27% and of having a hysterectomy was 12%. CONCLUSION: Fewer women are being hospitalized for minor surgical procedures for endometriosis with hospital-based care being reserved for more extensive procedures. Nonetheless, about a quarter of women hospitalized for initial surgical treatment for endometriosis will undergo additional surgical treatment within 4 years, and one in 10 will have a hysterectomy.     

Non-invasive prenatal testing for fetal sex determination: is ultrasound still relevant?

Early prenatal diagnosis of fetal sex is necessary to optimize pregnancy management in families known to be at risk of some heritable disorders. The demonstration of cell-free fetal DNA (cffDNA) in the mother's blood has made it possible to identify Y chromosome sequences in maternal blood and to determine fetal sex noninvasively, during the first trimester. This procedure can significantly reduce the number of invasive procedures for women with fetuses at risk of sex-linked diseases and optimize the management of these pregnancies. Fetal sex can be diagnosed by ultrasound with the same sensitivity and specificity, but later in pregnancy.     

Perimenopausal management of ovarian endometriosis and associated cancer risk: When is medical or surgical treatment indicated?

In women with endometriosis, the lifetime risk of ovarian cancer is increased from 1.4% to about 1.9%. The risk of clear cell and endometrioid ovarian cancer is, respectively, tripled and doubled. Atypical endometriosis, observed in 1–3% of endometriomas excised in premenopausal women, is the intermediate precursor lesion linking typical endometriosis and clear cell/endometrioid tumors. Prolonged oral contraceptive use is associated with a major reduction in ovarian cancer risk among women with endometriosis. Surveillance ± progestogen treatment or surgery should be discussed in perimenopausal women with small, typical endometriomas. In most perimenopausal women with a history of endometriosis but without endometriomas, surveillance instead of risk-reducing bilateral salpingo-oophorectomy seems advisable. Risk-reducing salpingo-oophorectomy might benefit patients at particularly increased risk, but the evidence is inconclusive. Risk profiling models and decision aids may assist patients in their choice. Screening of the general perimenopausal population to detect asymptomatic endometriomas is unlikely to reduce disease-specific mortality.     

HIV testing in pregnancy: are we testing enough?

Objective  

The crucial first step in the prevention of mother-to-child transmission of HIV is awareness of pregnant women of their HIV status. The aim of this study was to define the percentage of patients who received HIV tests between 2001 and 2007 in a German city hospital.     

Routine Assessment of Fetal Lung Maturation: A 1996 Perspective?

Since fetal lung maturation tests first became established in clinical practice, there have been many advances in perinatal medicine. Many clinical guidelines no longer emphasize the importance of routine fetal lung maturation stw:lies. Despite these advances, fetal lung maturation studies are commonly performed. This article reviews the development of fetal lung maturity testing, discusses the clinical value of the test when first introduced, and questions the role of the test in 1996.     

Parietal peritoneal closure versus non-closure at caesarean section: which technique is feasible to perform?

Abstract

Objective: To evaluate short-term effects of closure versus non-closure of the parietal peritoneum at caesarean section.

Methods: A randomized controlled study of women undergoing caesarean section was conducted at the obstetrics department of a research and education hospital between October 2010 and May 2011. Patients were randomly assigned to have closure of parietal peritoneal layer (Group I, n?=?55), and non-closure of parietal peritoneal layer (Control, Group II, n?=?55). Intra-operative and post-operative outcomes were compared between the groups.

Results: Groups were similar for baseline characteristics. Although there was statistically significant difference between Group 1 and Group 2 in terms of time to oral intake and mobilization time [12 (8–12) versus 8 (8–10)?h; p?<?0.001; 12 (8–12) versus 8 (8–10)?h; p?<?0.001]; the other variables, such as drop in hemoglobin concentration, estimate of blood loss, intra-operative additional sutures, operating time and time to passage of flatus [1.13?±?0.86 versus 1.41?±?0.82?g/dL; 487.9?±?217.01 versus 544.87?±?237.64?mL; 0 (0–1) versus 0 (0–1); 30.8?±?7.63 versus 31.6?±?10.38?h; 18.2?±?6.04 versus 18.2?±?4.23?h, p?>?0.05] were not statistically different between Group 1 and Group 2.

Conclusions: Closure of the parietal peritoneum has no benefit over non-closure of parietal peritoneum and non-closure is associated with rapid post-operative recovery.
