The impact of a nationwide hands-on workshop on the diagnostic rates and management of obstetrical anal sphincter Injuries in Israel.

AIM: The aim was to evaluate the influence of a half day, hands-on, workshop on the detection and repair of obstetric anal sphincter injuries (OASIs). METHOD: Starting in February 2011, hands-on workshops for the diagnosis and repair of OASIs were delivered by trained urogynaecologists in departments of tertiary medical centres in Israel. The structure of the hands-on workshop resembles the workshop organized at the International Urogynecological Association annual conferences. Participants included medical staff, midwives and surgical residents from each medical centre. We collected data regarding the rate of OASIs, 1 year before and 1 year following the workshop, in 11 medical centres. The study population was composed of parturients with the following inclusion criteria: singleton pregnancy, vertex presentation and vaginal delivery. Pre-viable preterm gestations (< 24 weeks), birth weight < 500 g, stillborn, and those with major congenital anomalies, multifoetal pregnancies, breech presentations and caesarean deliveries were excluded from the analysis. RESULTS: In the reviewed centres, 70 663 (49.3%) women delivered prior to the workshop (pre-workshop group) and 72 616 (50.7%) women delivered following the workshop (post-workshop group). Third- or fourth-degree perineal tears occurred in 248 women (0.35%) before the workshop, and in 328 (0.45%) following the workshop, a significant increase of 28.7% (P = 0.002). The increase in diagnosis was significant also in women with third-degree tears alone, 226 women (0.32%) before the workshop and 298 (0.41%) following the workshop, an increase of 28.3% (P = 0.005). CONCLUSION: The detection rate of OASIs has significantly increased following the hands-on workshop. The implementation of such programmes is crucial for increasing awareness and detection rates of OASI following vaginal deliveries.

Long-term efficacy of Paula method as compared with pelvic floor muscle training for stress urinary incontinence in women: a 6-month follow-up.

PURPOSE: The purpose of this study was to examine the long-term efficacy of an exercise regimen based on circular muscle strengthening (Paula method) as opposed to pelvic floor muscle training (PFMT) on stress urinary incontinence symptoms at 6 months postintervention. SUBJECTS AND SETTING: Of 240 women who had initially participated in a randomized clinical trial, 143 women suffering from stress urinary incontinence participated in this follow-up study. METHODS: Subjects participated in a randomized controlled clinical trial comparing 2 exercise programs (12 private Paula lessons vs 6 group PFMT lessons) over a 12-week period. Of these, 143 women took part in the follow-up study: 64 from the Paula group and 79 from the PFMT group. Six-month follow-up data were gathered via telephone interviews. RESULTS: No significant deterioration in stress urinary incontinence symptoms occurred 6 months after completion of the interventions in either group. We found a statistically significant difference between the groups with regard to reported frequency of urinary leakage; 25 of subjects (39.7%) allocated to the Paula method reported a low frequency rate of incontinence episodes upon completion of the study as compared to 18 (22.8%) in the PFMT group (P = .03). Forty-nine of the 64 women in the Paula group (76.6%) and 62 of the 79 women in the PFMT group (78.5%) reported that they continued exercising 6 months after completion of the trial (P = .8). CONCLUSIONS: Both intervention methods reduced frequency of urinary incontinence over a 6-month period. Long-term adherence was similar in both groups. Pelvic floor muscle training was associated with fewer sessions and decreased cost and fewer lessons needed as compared with the Paula method. Nevertheless, results also suggest that the Paula method achieves a lower frequency of urinary leakage than PFMT.

Posterior intra-vaginal slingplasty for the treatment of vaginal apex prolapse: Medium-term results of 140 operations with a novel procedure.

OBJECTIVES: Urogynecologists are constantly looking for simple, safe and effective ways to cure vaginal apex prolapse. A novel surgical technique, posterior intra-vaginal slingplasty (PIVS), was reported recently to include both a high therapeutic rate and a low complication rate. The present study was aimed at evaluating the preliminary data of a series of PIVS-treated patients. STUDY DESIGN: A total of 140 patients with vaginal apex prolapse underwent the PIVS operation in a daycare setting. Pre-operative demographics, operative details and post-operative follow-up data were prospectively collected for all patients. RESULTS: The PIVS procedure dose requires neither laparotomy nor deep transvaginal dissection as previously required for operative intervention. No intra-operative complications were recorded. The hospitalization period was relatively short. Three patients (2.1%) presented with surgical failure, whereas 137 (97.8%) of the operated patients reported satisfaction with the therapeutic results. One patient had post-operative unilateral gluteal skin infection. She was treated by surgical removal of the infected hemi-tape. Twelve (8.6%) patients had vaginal tape protrusion, of which 11 underwent segmental tape resection at the outpatient clinic. Two patients had spontaneous rejection of the tape while the vaginal apex remained well suspended. One patient suffered from post-operative fever of unknown origin, which was effectively treated with oral antibiotics. CONCLUSIONS: The novel PIVS operation reduces the complication rate and shortens the rehabilitation period previously reported for the types of operation designed in the past to cure vaginal apex prolapse. The current list of results supports the previously reported efficacy, safety and simplicity of this procedure. However, more long-term data are required to be able to draw solid conclusions concerning the superiority of the discussed operative technique.

[A new minimally invasive procedure for the conservative treatment of uterine prolapse--the posterior IVS].

BACKGROUND: The risk of women who undergo surgery for the treatment of pelvic organ prolapse (POP) by the age of 80 is reported to exceed 10%, and is expected to rise with the increase in life expectancy. Most women affected are in their 5th or 6th decade, and the majority will suffer other medical problems. The current medical literature asserts that the vaginal surgical approach for POP operations are followed by less complications and provide a shorter rehabilitation period than the abdominal route. Hysterectomy is widely accepted as part of POP reconstructive surgery whenever the uterus is significantly prolapsed, however, there is no clear evidence to support the role of hysterectomy in improving surgery outcome. We present our experience with a new minimally invasive procedure - the posterior intravaginal slingplasty (IVS) for utero-suspension in the presence of moderate and advanced uterine prolapse. AIM: To evaluate the feasibility, intra- and post-operative complications and short term results of the posterior IVS procedure and uterosuspension for uterine prolapse. METHODS: Reconstructive surgery using the posterior IVS was performed on 18 women with moderate to severe uterine prolapse who chose to preserve their uterus. Patients were then followed 1,6,12 months and 2 years post-operatively to assess any recurrence of pelvic organ prolapse. RESULTS: No major intra- or post-operative complications were reported. Follow-up of one to 13 months showed good results. CONCLUSIONS: Reconstructive POP surgery may not necessitate hysterectomy. The posterior IVS is a novel safe, minimally invasive, simple and effective surgical procedure for the treatment of POP, permitting uterine preservation. A larger number of patients and a longer follow-up period are required for proper evaluation of the actual safety and efficacy of this procedure.

Interleukin-1-mediated stimulation of prostaglandin E production is without effect on plasminogen activator activity in human granulosa lutein cell cultures.

In continuation of earlier observations on the involvement of interleukin-1 (IL-1) in ovarian function, we examined the ability of IL-1 to modulate plasminogen activator (PA) activity and prostaglandin (PG) synthesis in human granulosa lutein cells (GLCs). Toward this goal, GLCs were obtained from women undergoing in vitro fertilization, preincubated with 10% fetal calf serum for 48 h, and subsequently cultured for 48 h in serum-free media in the absence or presence of IL-1 beta (10 ng/mL). Cellular PA activity was measured by plasminogen-dependent cleavage of the chromogenic substrate H-D-valyl-L-leucyl-L-lysine-p-nitroanilide (S-2251). Prostaglandin E (PGE) levels were assayed by conventional RIA. Exposure of GLCs to IL-1 resulted in a 50% increase in PGE production, a 33% suppression of PA activity, and a 75% increase in the ability of the corresponding conditioned media to inhibit exogenous urokinase activity. The inhibitory capacity was attributable to an IL-1-mediated increase in PA inhibitor type-1 (PAI-1) production, inasmuch as urokinase inhibition could be abolished by the administration of a polyclonal antihuman PAI-1 immunoglobulin G. IL-1 treatment had no effect on plasmin or trypsin inhibition. Exposure of GLCs to IL-1 receptor antagonist abolished the ability of IL-1 to enhance PA inhibitory activity and PGE production, thereby establishing specific IL-1 receptor-mediated effects. The ability of IL-1 to suppress PA activity and to produce PAI-1 persisted in the presence of indomethacin, a potent inhibitor of PG synthesis. Likewise, transforming growth factor-beta 1 suppressed the ability of IL-1 to stimulate PGE production without affecting the IL-1-induced effects on the PA system. The present findings suggest a pluripotent response of GLCs to IL-1, characterized by the induction of PAI-1 and the suppression of PA occurring concurrent with, but independent of, PG production. These observations support the potential involvement of IL-1 in the regulation of human ovulatory processes.

Risk of fetal loss in twin pregnancies undergoing second trimester amniocentesis(1).

OBJECTIVE: To assess the rate of fetal loss among bichorionic twin gestations undergoing genetic amniocentesis compared with singletons undergoing the procedure and untested twins. METHODS: In a retrospective cohort study, three groups were compared: 476 women with twins undergoing amniocentesis, 489 women with singleton gestations undergoing amniocentesis, and 477 women with twins presenting at a similar gestational age for ultrasound studies only. All subjects were scanned at 17-18 weeks' gestation and again approximately 4 weeks after the procedure or first ultrasound scan. Excluded were twin pregnancies after fetal reduction or chorionic villus sampling, fetuses with structural anomalies, and cases in which one fetus had died at the time of examination or after fetal reduction. RESULTS: Thirteen twin gestations in the tested group (2.73%) aborted spontaneously up to 4 weeks after the procedure compared with three twin controls (0.63%, P =.01) and three post-procedure singleton controls (0.6%, P =.01). An abnormal karyotype was discovered in 15 tested twin pregnancies (3%) and in six tested singletons (1.23%). All affected twin pairs were discordant for the chromosomal anomaly. CONCLUSION: The risk of early fetal loss in twins undergoing amniocentesis appears to be higher than that of exposed singletons or unexposed twins.

Young low responders protected from untoward effects of reduced ovarian response.

OBJECTIVE(S): To correlate fertilization and clinical pregnancy rates (PRs) in low responders with their E2 levels (<500, 500-800, >800-1,000 pg/mL), age (20-30, 31-40, >40 years), number of follicles, and number of oocytes retrieved. DESIGN: A retrospective study. SETTING: The IVF unit of an academic hospital. PATIENT(S): One hundred forty-three women who failed to attain E2 levels of 1,000 pg/mL on the day of hCG administration. INTERVENTION(S): Controlled ovarian hyperstimulation, blood E2 and progesterone measurements, ultrasonographic scanning of ovarian follicles, oocyte retrieval after hCG administration, and ET. MAIN OUTCOME MEASURE: Clinical PR. RESULT(S): Although E2 levels, fertilization rates, age, and number of oocytes did not differ significantly between the three age groups, the PR achieved in the youngest group was approximately three times as high (19.3%) as that achieved in the two older groups. CONCLUSION: Young low responders represent a unique subset in that their age protects them from the deleterious effects of poor ovarian response.

Observer variability in the diagnosis and management of the hysterosalpingogram.

OBJECTIVE: To determine the reproducibility of hysterosalpingogram (HSG) interpretation and clinical management recommendations among trained observers. DESIGN: Fifty HSG films were distributed to five fertility practitioners with a mean of 20 years clinical experience. Each observer evaluated components of uterine and tubal status and provided clinical recommendations for hysteroscopy and laparoscopy. SETTING: University hospital-affiliated reproductive endocrine practice. INTERVENTION(S): None MAIN OUTCOME MEASURE(s): The level of agreement among observers for each uterine and tubal category as determined by the kappa(kappa) statistic. Determinants of clinical recommendation for further diagnostic studies were assessed. RESULT(S): The level of agreement between observers as determined by kappa ranged from 0.645 in the hydrosalpinx category, indicating fair reliability, to 0.111 for pelvic adhesions, indicating poor reliability. The composite kappa for uterine status was 0.345 whereas the composite kappa for tubal status was 0.430. Agreement among observers concerning management showed marginal reproducibility with a kappa of 0.261. Overall, more than one abnormality of either the cavity or the fallopian tubes led to a diagnostic recommendation for further workup in > or = 90% of cases. CONCLUSION(S): In a group of five experienced clinicians, there was considerable variability in the interpretation as well as the clinical management of the HSG. Physicians caring for infertile couples should be aware of this discrepancy and should, if possible, review carefully both the original films as well as the report of the attending radiologist in formulating their diagnostic evaluation and management plan.

Characterization of intraperitoneal cytokines and nitrites in women with severe ovarian hyperstimulation syndrome.

OBJECTIVE: To assess the potential involvement of cytokines and nitrites in the hyperpermeability characterizing the ovarian hyperstimulation syndrome (OHSS). DESIGN: A controlled clinical study comparing peritoneal fluid (PF) from patients with severe OHSS and from non-OHSS controls. SETTING: Women hospitalized with severe OHSS in three tertiary medical centers. PATIENTS: Twelve patients with severe OHSS necessitating paracentesis and 20 non-OHSS controls. INTERVENTIONS: The criteria for ultrasound-guided paracentesis were tense ascites, hydrothorax, hemoconcentration, or oliguria. MAIN OUTCOME MEASURES: Interleukin (IL) 1 beta IL-1 receptor agonist, IL-2, IL-6, IL-8, and tumor necrosis factor alpha (TNF alpha) levels in PF were assayed by ELISA; nitrites were measured by the "Griess" reaction. Estradiol and P were determined by RIA. RESULTS: Ovarian hyperstimulation syndrome patients had significantly higher PF IL-6 (3,523 versus 30 pg/mL), TNF alpha (14 versus 4.2 pg/mL), and IL-8 (1,695 versus 900 pg/mL). In the serum, only IL-6 levels were significantly higher (375 versus 11 pg/mL). Conversely, nitrite levels were significantly lower in PF of OHSS patients (0.5 versus 34 nmol/mL). Interleukin 1 levels were higher and IL-1 receptor antagonist levels were lower in OHSS patients, suggesting potentially increased biologic potency of IL-1. CONCLUSION: These findings suggest that these substances could be involved in mediating the capillary hyperpermeability characterizing this syndrome.

Human trophectoderm apposition is regulated by interferon γ-induced protein 10 (IP-10) during early implantation.

INTRODUCTION: The first step in human implantation is the attraction of the blastocyst to the endometrium. We aimed to study attraction of the human blastocyst to the endometrium, and how this process is accomplished by chemokines secreted by the endometrium. MATERIALS AND METHODS: Blastocyst trophectoderm cells and other trophoblast lineage cells were subjected to attraction assays by IP-10 and other chemokines using transwell migration and chemotaxis assays. Chemokine expression and secretion were investigated using immunohistochemistry, ELISA, FACS analysis, and RT-PCR on material from flushing of the uterine cavity in endometrial biopsies. Chemokine receptor expression by blastocyst trophectoderm following PGD biopsy, trophectoderm derived from hES, placental villi, and other trophoblast lineage cells were characterized by the same methods. RESULTS: IP-10 dramatically attracted trophectoderm derived from hES cells and other lineages by interaction with CXCR3 chemokine receptors, as shown by both chemotaxis and transwell migration. High levels of IP-10 were detected throughout the menstrual cycle at flushing of the uterine cavity. Immunohistochemistry, FACS analysis, and RT-PCR of endometrial biopsy detected IP-10 in glandular and stromal cells of the endometrium. High levels of IP-10 were detected in condition medium of the endometrial stromal and glandular cells. Of all of the chemokine/chemokine receptor combinations examined, the IP-10/CXCR3 interaction was the only cytokine that was significantly elevated. DISCUSSION: While they await the wandering blastocyst, IP-10 is produced by many cells of the endometrium, but not by endometrial natural killer cells. CONCLUSION: Endometrial IP-10 may specifically attract human blastocyst trophectoderm cells early in implantation.

Concordance between one-hour pad test and subjective assessment of stress incontinence.

OBJECTIVES: To examine the concordance among the 1-hour pad test results, subjective questions regarding incontinence, and a quality-of-life questionnaire to assess the role of the pad test as a noninvasive measurement tool in clinical trials. The 1-hour nonstandard pad test is one of several quantitative tools used to measure urinary incontinence; however, its utility has been questioned. METHODS: The study subjects were women participating in 2 clinical trials evaluating noninvasive interventions: circular muscle exercises versus pelvic floor muscle training for urinary incontinence. The quantity of urinary leakage according to the pad test and questions regarding subjective urinary leakage from the quality-of-life questionnaire were evaluated for all study subjects combined and in subgroups. RESULTS: A total of 731 clinical pad tests were evaluated from the 2 trials. Significant associations were found between several questions regarding subjective leakage and the pad test results in the study subgroups. A significant correlation was seen between the pad test results and the quality-of-life questionnaire scores (r = 0.14 before intervention and r = 0.42 after intervention in the combined studies; P < .05). CONCLUSIONS: The 1-hour pad test demonstrated concordance with subjective assessment tools for urinary incontinence and should be considered a part of the armamentarium for assessing the severity of this condition.

Randomized trial of circular muscle versus pelvic floor training for stress urinary incontinence in women.

BACKGROUND: Conservative management, such as pelvic floor muscle training (PMFT), is commonly recommended as first-line therapy for women with stress urinary incontinence (SUI). METHODS: We randomly assigned 245 women with SUI to 12 weeks of circular muscle exercises (Paula method) or PMFT in order to assess whether these approaches are equivalent. End points after 12 weeks included urinary leak as measured by a 1-hour pad test, subjective assessment of incontinence, and quality of life (QOL). Cure was defined as urinary leakage of <1 g. RESULTS: The mean decrease in urinary leakage was 7.9 g (SD 12.1) among women in the Paula group and 8.9 g (SD 18.2) in the PFMT group (90% confidence interval [CI] of between-group difference was -4.68 g to 3.0 g). This did not meet the prespecified criterion for equivalence. There were 15.2% (p = 0.04) more cures in those randomized to the Paula method. Improvement in subjective urinary complaints and QOL was observed in both groups. The study was limited by a dropout rate of 26.6%. CONCLUSIONS: Both methods are efficacious in women with SUI. The results suggest superiority of the Paula method in terms of cure rate.

Conservation of the prolapsed uterus is a valid option: medium term results of a prospective comparative study with the posterior intravaginal slingoplasty operation.

It has been reported that, by the age of 80, the risk of women to undergo surgery for the treatment of pelvic organ prolapse (POP) exceeds 10%, a percentage expected to increase with the rise in life expectancy. The vaginal approach for POP reconstructive operations is associated with fewer complications and results in a shorter rehabilitation period than the abdominal route, whereas hysterectomy is widely performed concomitantly whenever the uterus is significantly prolapsed. However, there is no clear evidence supporting the role of hysterectomy in improving surgery outcome. We present our experience with a new minimally invasive procedure--the posterior intravaginal slingplasty (PIVS) for correction of advanced uterine prolapse--at the same time, comparing additive vaginal hysterectomy to uterine preservation, to evaluate the therapeutic significance of hysterectomy when vaginal apical prolapse is reconstructed with PIVS. Seventy-nine women presenting with moderate to severe uterine prolapse were enrolled into the current PIVS study. Vaginal hysterectomy was concomitantly performed upon patient's request (44 patients), whereas those wishing to preserve their uterus underwent reconstructive surgery only (35 patients). No intraoperative or postoperative major complications were recorded during an average follow-up of 29.8 months: One patient (1.3%) presented with surgical failure, whereas 71 (89.9%) of the operated patients reported satisfaction with the therapeutic results. Bladder overactivity symptoms declined from three thirds of the patients preoperatively to below 10% postoperatively. Ten (12.7%) patients had vaginal tape protrusion; all underwent segmental tape resection at the out-patient clinic. Because the PIVS procedure does not require either laparotomy or deep transvaginal dissection, as previously required for operative intervention, the hospitalization period was relatively short: 4.2 days for the hysterectomy group and 1.5 for the non-hysterectomy group. Other statistically significant differences between the hysterectomy and non-hysterectomy groups were the average ages (63.5 vs 51.0 years, respectively) and concomitant surgery (87% vs 69%, respectively, the higher percentage due to additive amputation of elongated uterine cervices). No other significant differences were recorded. The current results support the previously reported efficacy, safety, and simplicity of the PIVS procedure as well as the legitimacy of uterine preservation. Moreover, unstable bladder symptoms were found to be improved after this operation. However, long-term data are required to be able to draw solid conclusions concerning the superiority of the discussed operation.

Paula method of circular muscle exercises for urinary stress incontinence--a clinical trial.

The aim of this study was to determine the efficacy of the Paula method of circular muscle training in the management of stress incontinence (SI). The theory behind this method states that activity of distant sphincters affects other muscles. In a pilot study, 59 women, mainly hospital employees, were randomly assigned to participate in exercises according to the Paula method or pelvic floor training. Efficacy was measured by reports of incontinence, quality of life (I-QOL), pad test, and pelvic floor muscle strength (assessed by perineometer and digital examination). Both the Paula exercises and pelvic floor training produced significant changes in urinary leakage compared to baseline as measured by the pad test [mean decrease of 5.4 g (p=0.002) and 9.5 g (p=0.003), respectively]. Women randomized to the Paula method reported improvement in I-QOL scores. The Paula method was found to be efficacious for SI in a population of Israeli women. Larger community-based studies will be required to confirm these results and enable evaluation of between-group differences.

Third trimester torsion of persistent ovarian cyst following ovarian hyperstimulation--an unusual cause of preterm labor.

Herein, a patient being operated for cesarean section due to preterm labor in the 31st week of a triplet pregnancy induced by gonadotropins is being described. On celiotomy, peritoneal effusion was present secondary to torsion of a 10 x 6 cm right ovarian cyst. This uncommon finding contradicts the common belief that the chances for an ovarian cyst in the overcrowded peritoneal space due to a 40-week-size uterus to twist around its pedicle are remote. The possibility that preterm labor was initiated by the torsion is discussed.

Extraluminal hyperechogenic echo detected by transvaginal ultrasonography as a prognostic factor in recurrent hydatidiform mole.

Measuring beta hCG titers by either bioassay or radioimmunoassay has become the cornerstone in the management and treatment of hydatidiform mole. It is this very determination which will indicate either spontaneous remission or the need for chemotherapy treatment due to rising or plateauing titers. Herein, we report on the potential assistance of a unique ultrasonographic appearance of a hyperechogenic shadow located in the uterine wall, before and after an attempt for full evacuation of hydatidiform mole. The behavior of this echogenic area was more sensitive in predicting the course of the disease than did the beta hCG titers. Thus, using transvaginal sonography may serve as another predictor and indicator in evaluating the treatment of hydatidiform mole.

Increased middle cerebral artery blood flow impedance in fetal subdural hematoma.

This case describes the prenatal diagnosis at 30 weeks' gestation of a posterior fossa subdural hematoma. Doppler velocimetry studies of the middle cerebral artery at that time showed an abnormally high resistance pattern with reverse end-diastolic flow. Ultrasonic assessment of the fetus indicated that there was associated quadriplegia. No cause for the lesion was demonstrated. A fetal blood sample, obtained by cordocentesis, revealed a normal karyotype. Fetal blood gas analysis was also normal. The pregnancy was terminated at the parents' request.

Spontaneous ovarian hyperstimulation syndrome and hyperreactio luteinalis are entities in continuum.

Hyperreactio luteinalis (HL) and spontaneous ovarian hyperstimulation syndrome (OHSS) are both rare conditions during pregnancy. The clinical presentation of HL and OHSS are comparable and both should be differentiated from ovarian carcinoma. We present a case of a 32-year-old woman who was initially seen with markedly enlarged multicystic ovaries and ascites in the 13th week of a spontaneously conceived pregnancy. Ultrasonographic follow-up and magnetic resonance imaging of the ovaries were employed in order to avoid exploratory laparotomy and rule out ovarian carcinoma. The patient received supportive therapy and delivered a healthy child at term. The increasing use of ultrasonography may lead to more frequent findings of multicystic ovaries in spontaneously conceived pregnancies. Making the distinction between HL and spontaneous OHSS in these cases may be difficult though clinically irrelevant as the approach to treatment is similar in both.
