A Fluid-Management Drape for Hysteroscopy: Innovation for Improved Patient Safety and Surgical Care.

BACKGROUND: Hysteroscopy requires accurate collection of unabsorbed distension media to measure patient fluid absorption. We assessed the effectiveness and usability of a novel total capture drape compared with a standard drape during hysteroscopy. METHOD: Simulation trials were followed by an early-phase study to compare fluid-capture efficiency and measures of drape usability during hysteroscopy randomizing the total capture drape compared with a standard drape. EXPERIENCE: Simulation trials indicated complete collection of unabsorbed fluid with the total capture drape and progressive loss of unabsorbed fluid with the standard drape. An early-phase study with 68 women found no statistical difference between groups for the hysteroscopic fluid deficit, but saw fewer cases with lost fluid in the total capture drape compared with the standard drape. Direct observation and focus group data indicated a trend for better capture of unabsorbed fluid with the total capture drape, along with increased usability once surgeons became familiar with correct placement. CONCLUSION: Simulation and early-phase study results are favorable for the total capture drape, demonstrating comparable fluid collection with the standard drape. With repeated use and in-service training, surgeons expressed greater confidence in the accuracy of the hysteroscopic fluid deficit with the total capture drape compared with the standard drape. Design modifications should improve overall usability and fluid-capture efficiency.

The association between fatty acid index and in vitro fertilization outcomes.

PURPOSE: Fatty acids have been shown to play an important role in oocyte competence and early implantation of the embryo. Our hypothesis-generating study sought to determine if individual fatty acids expressed as a percentage of total erythrocyte fatty acids are associated with embryo quality and other in vitro fertilization (IVF) outcomes. METHODS: This was a prospective cohort study at an academic fertility center. Sixty women undergoing their first IVF cycle were recruited. Serum measurements of 22 fatty acids were obtained. We calculated each fatty acid as a percentage of total fatty acids, defined as the index for that individual fatty acid. RESULTS: Omega-3 index had no correlation with IVF outcomes. A negative correlation was found between the trans fatty acid index, elaidic acid (EA), and IVF outcomes, including fertilization rate (r = - 0.261, p = 0.04), blastocyst conversion rate (r = - 0.41, p = 0.001), and number of usable blastocysts and embryos (r = - 0.411, p = 0.001). There was no correlation between EA index and number of oocytes retrieved, embryo grade, or clinical pregnancy. No consistent correlations were observed with the additional fatty acids analyzed. CONCLUSIONS: No correlation was observed between omega-3 index and IVF outcomes. Elevated erythrocyte EA index, the major trans fatty acid commonly consumed in hydrogenated oils, margarine, and fried foods, was negatively correlated with number of usable blastocysts and embryos, blastocyst conversion, and fertilization rate. Our findings suggest preliminary evidence that trans fat may be negatively associated with IVF outcomes.

Abnormal uterine bleeding in reproductive-aged women.

Abnormal uterine bleeding is a common medical condition with several causes. The International Federation of Gynecology and Obstetrics published guidelines in 2011 to develop universally accepted nomenclature and a classification system. In addition, the American College of Obstetrics and Gynecology recently updated recommendations on evaluation of abnormal uterine bleeding and indications for endometrial biopsies. This article reviews both medical and surgical treatments, including meta-analysis reviews of the most effective treatment options.

Sexual absorption of vaginal progesterone: a randomized control trial.

Objective. To determine if sexual intercourse reduces absorption of vaginal progesterone gel in women and to determine if progesterone is absorbed by the male during intercourse. Study Design. Prospective, randomized, cross over, controlled study of 20 reproductive-aged women and their male sexual partners randomized to receive vaginal progesterone gel (Crinone 8% gel, Actavis Inc., USA) or placebo cream. Serum progesterone for both male and female partners were measured 10 hours after intercourse. One week later, subjects were crossed over to receive the opposite formulation. In the third week, women used progesterone gel at night and abstained from intercourse. Results. Serum progesterone was significantly reduced with vaginal progesterone gel + intercourse compared with vaginal progesterone gel + abstinence (P = 0.0075). Men absorbed significant progesterone during intercourse with a female partner using vaginal progesterone gel compared to placebo (P = 0.0008). Conclusion(s). Vaginal progesterone gel is reduced in women after intercourse which may decrease drug efficacy during luteal phase support. Because men absorb low levels of progesterone during intercourse, exposure could cause adverse effects such as decreased libido. This study is registered under Clinical Trial number NCT01959464.

Influence of ejaculatory abstinence on seminal total antioxidant capacity and sperm membrane lipid peroxidation.

OBJECTIVE: To determine whether the period of ejaculatory abstinence (EA) influences the total antioxidant capacity (TAC) of semen or lipid peroxidation (LPO) of sperm membranes. DESIGN: A prospective experimental trial. SETTING: Academic medical center for reproductive endocrinology and infertility. PATIENT(S): Forty men from infertile couples planning intrauterine insemination. INTERVENTION(S): Men provided semen specimens after EA periods of 1 and 4 days. MAIN OUTCOME MEASURE(S): Semen analysis, peroxidase staining, and assays for seminal TAC and sperm membrane LPO, with measures compared between days 1 and 4 within individuals (internal control) using paired t tests. RESULT(S): The shorter period of EA (1 day vs. 4 days) resulted in statistically significant decreases in semen volume (-24%), sperm density (-28%), and total sperm count (-3.2%). There was a statistically significant increase in TAC with the shorter period of EA (1 day) compared with 4 days of EA. No difference was detected in sperm membrane LPO comparing 1 day of EA and 4 days of EA. CONCLUSION(S): Higher seminal TAC obtained after a shorter period of EA could diminish oxidative stress-induced sperm damage by a mechanism independent of LPO. Shorter periods of EA may thus improve sperm quality by protecting from reactive oxygen species damage, even though lower numbers of motile sperm are produced after a shorter period of EA. This would be consistent with prior research indicating improved results after intrauterine insemination under these circumstances.

Obstetric and gynecologic challenges in women with Ehlers-Danlos syndrome.

OBJECTIVE: To determine how often women with Ehlers-Danlos syndrome experience obstetric and gynecologic issues both compared with the general population and within the three most common subtypes of Ehlers-Danlos syndrome. METHODS: An anonymous, prospective, online questionnaire in English was posted to the Ehlers-Danlos National Foundation web site (http://ednf.org). RESULTS: Of the 1,769 of those who completed the survey, 1,225 reported a typed diagnosis of Ehlers-Danlos syndrome. Further stratification to the three most common types and reproductive-aged women (n=775) allowed conclusions to be made about differences in rates of obstetric complications and gynecologic dysfunction compared with the general population and between types of Ehlers-Danlos syndrome. Rates of obstetric outcomes for women who reported at least one pregnancy included term pregnancy in 69.7%, preterm birth in 25.2%, spontaneous abortion in 57.2%, and ectopic pregnancy in 5.1%. Infertility was reported by 44.1% of survey respondents. Normal menstrual cycles were reported by only 32.8% with intermenstrual bleeding occurring in 18.6%. Heavy menstrual bleeding was reported by 32.9% survey participants. Gynecologic pain reported included dysmenorrhea by 92.5% and dyspareunia by 77.0%. CONCLUSION: There is a much greater prevalence of obstetric and gynecologic issues reported by women with Ehlers-Danlos syndrome than in the general population. Additionally, rates differed significantly among the three most common types of Ehlers-Danlos syndrome with vascular type having the highest rates of adverse pregnancy outcomes and menstrual abnormalities. Physician providers should be aware of these challenges and should counsel patients with Ehlers-Danlos syndrome about relevant options and risks.

Association of blood type and patient characteristics with ovarian reserve.

OBJECTIVE: To assess whether blood type was associated with diminished ovarian reserve (DOR) (day-3 follicle-stimulating hormone level >10 IU/L), controlling for history of tobacco smoking, body mass index (BMI), history of endometriosis, ovarian surgery, previous pregnancy, and maternal age. DESIGN: Cross-sectional study. SETTING: Academic medical center, Division of Reproductive Endocrinology and Infertility. PATIENT(S): Women undergoing in vitro fertilization (IVF) from 2006-2011 (n = 305). INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Presence of DOR in relation to a patient's blood type. RESULT(S): Other investigators have reported an increased risk for DOR in patients with blood type O and a protective effect on ovarian reserve for blood type A. We observed no association between a woman's blood type and DOR. We found an increased risk for DOR in patients aged 35 and older. Obesity (BMI ≥ 30 vs. BMI <25) was associated with lower odds of DOR. CONCLUSION(S): In comparison with blood type A, blood type O is not associated with an increase in DOR. We found no clinical implications for using blood type as a risk factor for DOR.

Cancer, fertility preservation, and future pregnancy: a comprehensive review.

Given the increases in 5-year cancer survival and recent advances in fertility preserving technologies, an increasing number of women with cancer are presenting for discussion of fertility preserving options. This review will summarize the risk of infertility secondary to cancer treatment, available treatment options for fertility preservation, and techniques to reduce future risks for patients. Concerns that will be addressed include the risk of the medications and procedures, the potential delay in cancer treatment, likelihood of pregnancy complications, as well as the impact of future pregnancy on the recurrence risk of cancer. Recent advances in oocyte cryopreservation and ovarian stimulation protocols will be discussed. Healthcare providers need to be informed of available treatment options including the risks, advantages, and disadvantages of fertility preserving options to properly counsel patients.

A short period of ejaculatory abstinence before intrauterine insemination is associated with higher pregnancy rates.

Novel clomiphene "stair-step" protocol reduces time to ovulation in women with polycystic ovarian syndrome.

OBJECTIVE: The objective of the study was to determine the efficacy of a novel "stair-step" clomiphene protocol in women with polycystic ovarian syndrome (PCOS) who do not respond to 50 mg clomiphene. STUDY DESIGN: This was a retrospective analysis at an academic fertility center. The stair-step protocol is performed as follows: 50 mg clomiphene for 5 days, ultrasonography on days 11-14. If unresponsive, immediately begin 100 mg clomiphene for 5 days and repeat ultrasound in 1 week. If still unresponsive, begin 150 mg clomiphene for 5 days and repeat the ultrasound in 1 week. Stair-step cycles were compared with published historical clomiphene outcomes for women who were nonresponsive. RESULTS: The time to ovulation was 32-53 days less with the stair-step protocol compared with a traditional regimen. The dose-dependent ovulation rate was 64% at 100 mg with the stair-step protocol compared with 22% with a traditional regimen. CONCLUSION: It is not necessary to induce menses before increasing clomiphene doses in nonresponsive PCOS patients.

Absorption of vaginal estrogen cream during sexual intercourse: a prospective, randomized, controlled trial.

OBJECTIVE: To determine if intercourse changed serum estradiol levels in women using vaginal E2 cream or in their male partners. STUDY DESIGN: Prospective, randomized, placebo-controlled, crossover, blinded study of 10 postmenopausal women and their male sexual partners. Subjects were randomized to estradiol or placebo cream and intercourse, then crossed over after 7-14 days. Seven to 14 days later, the woman used vaginal estradiol cream and abstained from intercourse. Serum E2 levels were obtained 10-12 hours after each exposure. RESULTS: Serum E2 levels were higher in 8 of 10 men after intercourse with vaginal estradiol cream, and this resulted in a small but significant (p = 0.03) increase in the estradiol levels as compared to placebo. Paradoxically, intercourse resulted in markedly lower estradiol levels in women as compared to abstinence (p = 0.004). CONCLUSION: Men absorb vaginal estradiol during intercourse, whereas intercourse reduces estradiol absorption in women. Although serum estradiol levels were only mildly elevated in men, it is possible that long-term exposure could cause feminizing changes. In women, estradiol levels were markedly reduced by intercourse.

Ultrasound-directed transvaginal myolysis: preclinical studies.

The ultimate goal is to develop a safe vaginal ultrasound-directed myolysis needle to treat uterine myomas. The specific preclinical study objective was to determine the optimal power to coagulate myomas in hysterectomy specimens with a prototype needle in a prospective preclinical study with an echogenic insulated needle electrode. In phase I of the study, myolysis was performed with ultrasound guidance at various powers and times. In phase II, a 20-W coagulating current was applied at defined distances from the serosa and surface temperatures measured. Myolysis with 10 to 20 W applied 5 to 10 seconds was optimal, because tissue popping occurred at 30 W or more when the needle was 5 mm or less from the serosa. The serosal temperature was never elevated above physiological ranges at any distance at this setting. Ultrasound-directed transvaginal myolysis may provide another option for women with uterine myomas if it is proven safe and effective in future clinical studies. On the basis of the observations in these preclinical studies, myolysis with 20 W for 10 seconds should be a safe parameter for clinical research, because there is no increased serosal temperature at these settings.

Conservative management of placenta increta with selective arterial embolization preserves future fertility and results in a favorable outcome in subsequent pregnancies.

OBJECTIVE: To present a case of selective arterial embolization for the treatment of placenta increta in a patient with subsequent pregnancy. DESIGN: Case report and literature review. SETTING: Community-based hospital. PATIENT(S): A 31-year-old G2P1 woman with placenta increta presenting with delayed postpartum hemorrhage. INTERVENTION(S): Selective uterine artery embolization. MAIN OUTCOME MEASURE(S): Cessation of uterine hemorrhage, future pregnancy. RESULT(S): The patient's uterine bleeding immediately resolved. She subsequently delivered a healthy neonate at term without recurrence of abnormal placentation. CONCLUSION(S): Arterial embolization is effective for treating placenta increta in women who wish to preserve fertility. A review of the literature demonstrates a 76.9% success rate and an 11% complication rate.

Post-call cognitive function and satisfaction in medical students on different call schedules: a prospective observational pilot study.

OBJECTIVE: The purpose of this study was to evaluate the effects of 2 different call schedules on post-call cognitive function and satisfaction. STUDY DESIGN: This is a prospective observational pilot study of 20 third-year medical students. A computerized cognitive function test was administered to students with call every fourth night or a week of 12-hour "night float" shifts. Questionnaires were completed to assess satisfaction on different call schedules. RESULTS: There was no significant difference in cognitive functioning scores for students on either call schedule. Responses on questionnaires indicate that night float allows students to feel more alert for clinical duties (P = .03). CONCLUSION: There is no significant impact of sleep deprivation on cognitive scores; however, night float allows students to feel subjectively more alert for clinical duties.

Effect of progesterone supplementation in early pregnancy on the pregnancy outcome after in vitro fertilization.

A retrospective cohort study was performed to evaluate IVF clinical pregnancy rates and livebirth rates between patients receiving progesterone supplementation through the first trimester of pregnancy (first trimester protocol) at 12 weeks vs. discontinuation after a positive beta-hCG test 2 weeks after retrieval (luteal protocol) at 4 weeks of pregnancy. A similar rate of clinical pregnancies occurred at 7 weeks (81.8% luteal protocol vs. 85.8% first trimester protocol; P=.49) and for livebirth rates (76.8% luteal protocol vs. 75.0% first trimester protocol; P=.80), but a trend toward a higher rate of pregnancy loss after 7 weeks in the first trimester protocol group occurred (15.5% vs. 4.4%; P=.06), indicating that first trimester progesterone supplementation may support early pregnancy through 7 weeks by delaying miscarriage but does not improve livebirth rates.

Effects of fibrin sealant on single-layer uterine incision closure in the New Zealand white rabbit.

OBJECTIVE: To determine if the addition of fibrin sealant to incision closure in a rabbit uterine horn myomectomy model affects adhesion formation or strength of incision closure. DESIGN: Prospective randomized controlled trial. SETTING: Academic research center. ANIMAL(S): New Zealand white female rabbits. INTERVENTION(S): A pilot study revealed that the time interval for maximal uterine incision healing was eight weeks. Thirty New Zealand white rabbits underwent a 1-cm standardized myotomy incision on both uterine horns. A single interrupted stitch of 3-0 polygalactin suture was placed to reapproximate each incision. Fibrin sealant was then applied to one of each rabbit's horns (randomized). After eight weeks, the rabbits were killed, and the strength of myotomy closure was determined by measurement of maximal burst pressure for each uterine horn. Adhesion presence was recorded. MAIN OUTCOME MEASURE(S): Uterine burst pressure, adhesion presence. RESULT(S): The mean burst pressure was 267.8 (+/-75.8) mm Hg in the suture only group and 247.8 (+/-92.3) mm Hg in the suture and fibrin sealant group. There was no statistical difference in the presence of adhesions. CONCLUSION(S): Fibrin sealant did not strengthen myotomy repair nor did it reduce postoperative adhesion formation. There is no apparent advantage to fibrin sealant in this myomectomy model.

Uterine artery embolization as a treatment option for uterine myomas.

Information is still being collected on the long-term clinical responses and appropriate patient selection for UAE. Prospective RCTs have not been performed to compare the clinical results from UAE with more conventional therapies for symptomatic uterine leiomyomata. At least three attempts at conducting such RCTs have been unsuccessful because of poor patient accrual that related to differing patient expectation and desires, clinical bias, insurance coverage, and the tendency that patients who have exhausted other treatment options may be disposed more favorably to less invasive treatments. Other comparative studies have serious limitations. For example, the retrospective study that compared outcomes after abdominal myomectomy with UAE suggested that patients who received UAE were more likely to require further invasive treatment by 3 years than were recipients of myomectomy. Lack of randomization introduced a selection bias because women in the group that underwent UAEwere older and were more likely to have had previous surgeries. A prospective study of "contemporaneous cohorts," which excluded patients who had sub-mucosal and pedunculated subserosal myomas, sought to compare quality of life measures and adverse events in patients who underwent UAE or hysterectomy. The investigators concluded that both treatments resulted in marked improvement in symptoms and quality of life scores, but complications were higher in the group that underwent hysterectomy over 1 year. In this study,however, a greater proportion of patients who underwent hysterectomy had improved pelvic pain scores. Furthermore, hysterectomy eliminates uterine bleeding and the risk for recurrence of myomas. Despite the lack of controlled studies that compared UAE with conventional surgery, and despite limited extended outcome data, UAE has gained rapid acceptance, primarily because the procedure preserves the uterus, is less invasive, and has less short-term morbidity than do most surgical options. The cost of UAE varies by region, but is comparable to the charges for hysterectomy and is less expensive than abdominal myomectomy. The evaluation before UAE may entail additional fees for diagnostic testing, such as MRI, to assess the uterine size and screen for adenomyosis. Other centers have recommended pretreatment ultrasonography, laparoscopy, hysteroscopy, endometrial biopsy, and biopsy of large fibroids to evaluate sarcoma. Generally,after UAE the recovery time and time lost from work are less; however, the potential need for subsequent surgery may be greater when compared with abdominal myomectomy. Any center that offers UAE should adhere to published clinical guidelines,maintain ongoing assessment of quality improvements measures, and observe strict criteria for obtaining procedural privileges. After McLucas advocated that gynecologists learn the skill to perform UAE for managing symptomatic myomas, the Society of Interventional Radiology responded with a precautionary commentary on the level of technical proficiency that is necessary to maintain optimum results from UAE. The complexity of pelvic arterial anatomy, the skill that is required to master modern coaxial microcatheters, and the hazards of significant patient radiation exposure were cited as reasons why sound training and demonstration of expertise be obtained before clinicians are credentialed to perform UAE.A collaboration between the gynecologist and the interventional radiologist is necessary to optimize the safety and efficacy of UAE. The primary candidates for this procedure include women who have symptomatic uterine fibroids who no longer desire fertility, but wish to avoid surgery or are poor surgical risks. The gynecologist is likely to be the primary initial consultant to patients who present with complaints of symptomatic myomas. Therefore, they must be familiar with the indications, exclusions, outcome expectations, and complications of UAE in their particular center. When hysterectomy is the only option, UAE should be considered. Appropriate diagnostic testing should aid in the exclusion of most, but not all, gynecologic cancers and pregnancy. Other contraindications include severe contrast medium allergy, renal insufficiency, and coagulopathy. MRI may be used to screen women before treatment in an attempt to detect those who have adenomyosis; patients should be aware that UAE is less effective in the presence of solitary or coexistent adenomyosis. Because some women may experience ovarian failure after UAE, additional studies to determine basal follicle-stimulating hormone and estradiol before and after the procedure may provide insight into UAE-induced follicle depletion.UAE is a unique new treatment for uterine myomas, and is no longer considered investigational for symptomatic uterine fibroids. There is international recognition that data are needed from RCTs that compare UAE with surgical alternatives. Current efforts to provide prospective objective assessment of treatment outcomes and complications after UAE will help to optimize patient selection and clinical guidelines. FIBROID should provide critical data for the assessment of safety and outcomes measures for women who receive UAE for symptomatic uterine myomas.

Low-dose aspirin does not improve ovarian stimulation, endometrial response, or pregnancy rates for in vitro fertilization.

BACKGROUND: The purpose of this study is to determine if low-dose aspirin improved ovarian stimulation, endometrial response, or IVF pregnancy rates in our program. METHODS: Retrospective analysis of 316 consecutive IVF cycles from 1995 through 2001. Aspirin 80 mg daily was initiated at the start of luteal leuprolide in 72 cycles. The 244 controls received no aspirin during treatment. RESULTS: The live birth rate in aspirin users was 29%, slightly lower compared to 41% in the no aspirin control group (p = 0.07). Implantation rates were 21% with aspirin and 30% in the control population (p = 0.01). There was no difference in the maximal endometrial thickness between aspirin and non-aspirin groups. The two groups were similar regarding age, gonadotropin ampules, embryos, number of embryos transferred, prior parity, diagnosis, use of intracytoplasmic sperm injection, and stimulation protocol. CONCLUSION: Low-dose aspirin was not beneficial to IVF patients in our program. Aspirin does not enhance endometrial thickness, augment the ovarian response, or improve pregnancy rates.

Laparoscopic myomectomy for symptomatic uterine myomas.

OBJECTIVE: To evaluate the safety, efficacy, and techniques of laparoscopic myomectomy as treatment for symptomatic uterine myomas. DESIGN: Medline literature review and cross-reference of published data. RESULTS: Results from randomized trials and clinical series have shown that laparoscopic myomectomy provides the advantages of shorter hospitalization, faster recovery, fewer adhesions, and less blood loss than abdominal myomectomy when performed by skilled surgeons. Improvements in surgical instruments and techniques allows for safe removal and multilayer myometrial repair of multiple large intramural myomas. Randomized trials support the use of absorbable adhesion barriers to reduce adhesions, but there is no apparent benefit of presurgical use of GnRH agonists. Pregnancy outcomes have been good, and the risk of uterine rupture is very low when the myometrium is repaired appropriately. CONCLUSION(S): Advances in surgical instruments and techniques are expanding the role of laparoscopic myomectomy in well-selected individuals. Meticulous repair of the myometrium is essential for women considering pregnancy after laparoscopic myomectomy to minimize the risk of uterine rupture. Laparoscopic myomectomy is an appropriate alternative to abdominal myomectomy, hysterectomy, and uterine artery embolization for some women.
