Pelvic floor muscle strength evaluation in different body positions in nulliparous healthy women and its correlation with sexual activity

Objective: The aim of this study was to assess pelvic floor muscle (PFM) strength in different body positions in nulliparous healthy women and its correlation with sexual activity.Materials and Methods: Fifty healthy nulliparous women with mean age of 23 years were prospectively studied. Subjective evaluation of PFM was assessed by transvaginal digital palpation (TDP) of anterior and posterior areas regarding the vaginal introitus. A perineometer with inflatable vaginal probe was used to assess the PFM strength in four different positions: supine with extended lower limbs (P1); bent-knee supine (P2); sitting (P3); standing (P4).Results: Physical activity, 3 times per week, was reported by 58% of volunteers. Sexual activity was observed in 80% of women and 82% of them presented orgasm. The average body mass index (BMI) was 21.76 kg/m(2), considered as normal according World Health Organization (WHO). We observed that 68% of volunteers were conscious about the PFM contraction. TDP showed concordance of 76% when anterior and posterior areas were compared (p = 0.00014). There was not correlation between PFM strength and orgasm in subjective evaluation. The PFM strength was significantly higher in standing position when compared with the other positions (p < 0.000). No statistical difference was observed between orgasm and PFM strength when objective evaluations were performed.Conclusions: There was concordance between anterior and posterior areas in 76% of cases when subjective PFM strength was assessed. In objective evaluation, higher PFM strength was observed when volunteers were standing. No statistical correlation was observed between PFM strength and orgasm in nulliparous healthy women.

Biotecnologias aplicadas à reprodução de éguas velhas

The acceptance of biotechnology for the most equine breeders association had a significant effect in the horse industry, gaining popularity around the world, because the increasing on the genetic gain, allowing the use of sub fertile mares and stallions with high genetics value on reproduction. The embryos in vitro production of human and cattle has been used with success, however in vitro embryo production is not efficient in the horse, as oocyte transfer (OT) and intracytoplasmatic sperm injection (ICSI). The oocyte transfer has been used especially in subfertile old mares presenting reproductive pathologies as: endometrite, cervical and uterine adhesions, blocked oviduct, perineal laceration and ovulation failures. During oocyte recovery process, the oocytes must be collected from immature follicles that need be matured in vitro or in vivo matured oocytes from pre-ovulatory follicles through the transvaginal aspiration guided by ultrasound. The recovered oocyte is transferred to a previously inseminated recipient mare, through the flank laparotomy. The intracytoplasmatic sperm injection (ICSI) is a procedure of in vitro fertilization that needs only one sperm that is aspirated and injected inside the oocyte. The oocytes used, can be from mature and immature follicles. Fresh, cooled and frozen semen can be used, because the procedure not requires a functional sperm. The use of Piezo drill resulted in a breakthrough the pellucid zone, allowing the vibration per minute provided in the sperm injection pipette, a major result of cleaved oocytes, due to a better sperm injection in the oocyte. The embryo transfer can be straight inside the oviduct, as also transcervical transferred after embryo culture produced in vitro. In conclusion both procedures (OT and ICSI) are effective to be used on equine assisted reproduction, getting results even lower than expected, but satisfactory from animal genetically superior

Dinâmica folicular ovariana e bases para a aplicação das biotécnicas da reprodução em bovinos

In the last years Brazil has achieved a leading position in worldwide cattle breeding. This country is consolidating the practice of an intensive and technical level cattle breeding, due to greater emphasis on reproductive efficiency and genetic improvement. The attention given to reproductive efficiency became to enhance the genetic improvement process, by exploiting the full reproductive potential of the animals. The biotechniques applied to reproduction arised to expand the reproductive potential for greater economic return. Are the most important reproductive biotechniques the FTAI and in vivo and in vitro embryo production for embryo transfer. Different hormonal treatments are consolidating to interfere with normal physiology in order to achieve the desired goals. The FTAI works to increase the reproductive rates of cattle through pre-booked artificial insemination in all the females in reproduction, without the need for estrous detection. The in vivo and in vitro embryo production aims to distribute the genetics of males and females genetically improved by transferring their embryos to genetically inferior females. Superovulation treatments designed to prevent the mechanism of dominance, which results in many follicles ovulating simultaneously for in vivo embryo production. To the in vitro embryo production, the technique of ovarian puncture guided by transvaginal ultrasound allows to aspirate a number of quality oocytes. The application of biotech is based on knowledge of the female and ovarian reproductive physiology and knowledge of their acting in different breeds and environments.

Reliability of pelvic floor muscle strength assessment in healthy continent women

Background: The aim of this study was to compare pelvic floor muscle (PFM) strength using transvaginal digital palpation in healthy continent women in different age groups, and to compare the inter- and intra-rater reliability of examiners performing anterior and posterior vaginal assessments.Methods: We prospectively studied 150 healthy multiparous women. They were distributed into four different groups, according to age range: G1 (n = 37), 30-40 years-old; G2 (n = 39), 41-50 years-old; G3 (n = 39), 51-60 years-old; and G4 (n = 35), older than 60 years-old. PFM strength was evaluated using transvaginal digital palpation in the anterior and posterior areas, by 3 different examiners, and graded using a 5-point Amaro's scale.Results: There was no statistical difference among the different age ranges, for each grade of PFM strength. There was good intra-rater concordance between anterior and posterior PFM assessment, being 64.7%, 63.3%, and 66.7% for examiners A, B, and C, respectively. The intra-rater concordance level was good for each examiner. However, the inter-rater reliability for two examiners varied from moderate to good.Conclusions: Age has no effect on PFM strength profiles, in multiparous continent women. There is good concordance between anterior and posterior vaginal PFM strength assessments, but only moderate to good inter-rater reliability of the measurements between two examiners.

Evaluation of clinical, ultrasonographic and hysteroscopic parameters in the differentiation of endometrial polyps and cancer of endometrium

Study Objective: To evaluate the diagnostic accuracy of transvaginal ultrasound and office hysteroscopy in the differentiation between endometrial polyps and endometrial adenocarcinoma. Design: This is a prospective 100 women longitudinal study, 24 to 80 years, submitted to hysteroscopic polypectomy (n = 80) or surgery due to endometrial adenocarcinoma (n = 20), from january 2010 to December 2011. Clinical, ultrasonographic and hysteroscopic parameters were analyzed and compared with histopathologic find. Statistical analysis were performed utilizing the Tukey, Kruskal-Wallis, Dunn and Mann-Whitney test, with a confidence interval of 95% and p\0, 05 statiscally significant. Setting: Botucatu Medical School. Intervention: Prospective analysis of clinical, ultrasonographic and hysteroscopic parameters in patients with diagnosis suspected of endometrial polyps and adenocarcinoma of endometrium were performed. According to the diagnosis, hysteroscopic polypectomy or pan hysterectomy with lymph node sampling was realized. After the surgery and histopathological study, statistical analysis of parameters was performed and the results were compared between groups. It was Research Ethics Committee approved. Measurements and Main Results: There were no differences between age, BMI, menopause, TH use and associated diseases among groups. The main symptom of endometrial cancer was the postmenopausal bleeding, affecting 84,2% of women against 34,8% of polypectomy group. The majority of women with endometrial polyps were asymptomatic. Transvaginal ultrasonography showed no ability to differentiate cases of endometrial cancer compared with the cases of endometrial polyps, considering the presence of endometrial thickness and blood flow on color Doppler. Office hysteroscopy showed significant changes in 75% of the adenocarcinoma cases, especially the presence of diffuse hypervascularity with atypical vessels. Conclusion: Still remains an inability to establish clinical parameters and reliable ultrasound imaging to differentiate endometrial polyps and cancer of endometrium. Attention should be given to hysteroscopic exams presenting diffuse endometrial hypervascularization with architectural distortion of the vessels. The recommendation of our service remains the systematic removal of all endometrial polyps.

Avaliação da cavidade uterina com histerossonografia, uma revisão

Sonohysterography was firstly described three decades ago. The saline solution infusion into the uterine cavity favors its use and provides excellent visualization of the anatomy and the inner cavity of the uterus better than the conventional transvaginal sonography To check the current role of sonohysterography in the uterine cavity assessment in women with abnormal uterine bleeding and asymptomatic, a literature review comparing sonohysterograph with conventional transvaginal sonography and/or ambulatory diagnostic hysteroscopy was carried out. To this end, relevant studies were researched in electronic databases Medline/PubMed, SciELO/LILACS. The sonohysterography is an ambulatory procedure, non-invasive, better cost-benefit, better sensitivity and specificity to identify uterine abnormalities, causing minimal discomfort and low complications rate. It was subject to revision which there is no more doubt about its accuracy. It can be concluded that the sonohysterography is a useful tool in the propedeutics to assess uterine cavity of symptomatic patients with abnormal uterine bleeding, infertility, recurrent miscarriages, and embryonic implantation failures in assisted reproduction treatment / in vitro fertilization and in any other intra and extra uterine cavity alteration. Hence, conventional transvaginal sonography is indicated as an initial method of assessment of the uterine cavity previously to ambulatory diagnostic hysteroscopy.

Unilateral ablation of follicles >= 4 mm leads to compensatory follicle response from the contralateral ovary in heifers

In each of two experiments, heifers were assigned to a control group and a unilaterally ablated (UA) group (n = 6/group). In the UA group, follicles >= 4 mm in the left ovary were ablated by transvaginal ultrasound-guided technique at Hour 0 (8:00 AM) on the day of ovulation. Follicles in the CL-bearing right ovary remained intact. In Experiment 1, ablations continued until the next ovulation, and new follicles emerged in the right ovary in 9 of 14 (64%) waves. The number of follicles/wave (combined, 6.4 +/- 0.4) did not differ between groups. In Experiment 2, follicles were counted at Hours 0, 4, 8, 12, and 24; the resistance index (RI) for blood flow in the ovarian pedicle was determined at Hours 0 and 12; and blood samples were collected every hour from Hours 0 to 12 and Hour 24. An increase (P < 0.05) in the number of follicles in the follicle-intact ovary began at Hour 4 with complete compensation by Hour 24. Concentrations of FSH did not change between Hours 0 and 24 in the UA group but decreased (P < 0.05) in the controls by Hour 7. At Hour 12, RI to the right ovary approached being lower (P < 0.06) in the UA group than in the control group. Results indicated that unilateral ablation of follicles >= 4 mm led to compensatory follicle response in the follicle-intact ovary, and initially circulatory FSH concentrations were maintained and blood flow to the follicle-intact ovary increased.

Vaginal progesterone in women with an asymptomatic sonographic short cervix in the midtrimester decreases preterm delivery and neonatal morbidity: a systematic review and metaanalysis of individual patient data

OBJECTIVE: To determine whether the use of vaginal progesterone in asymptomatic women with a sonographic short cervix (<= 25 mm) in the midtrimester reduces the risk of preterm birth and improves neonatal morbidity and mortality. STUDY DESIGN: Individual patient data metaanalysis of randomized controlled trials. RESULTS: Five trials of high quality were included with a total of 775 women and 827 infants. Treatment with vaginal progesterone was associated with a significant reduction in the rate of preterm birth <33 weeks (relative risk [RR], 0.58; 95% confidence interval [CI], 0.42-0.80), <35 weeks (RR, 0.69; 95% CI, 0.55-0.88), and <28 weeks (RR, 0.50; 95% CI, 0.30-0.81); respiratory distress syndrome (RR, 0.48; 95% CI, 0.30-0.76); composite neonatal morbidity and mortality (RR, 0.57; 95% CI, 0.40-0.81); birthweight <1500 g (RR, 0.55; 95% CI, 0.38-0.80); admission to neonatal intensive care unit (RR, 0.75; 95% CI, 0.59-0.94); and requirement for mechanical ventilation (RR, 0.66; 95% CI, 0.44-0.98). There were no significant differences between the vaginal progesterone and placebo groups in the rate of adverse maternal events or congenital anomalies. CONCLUSION: Vaginal progesterone administration to asymptomatic women with a sonographic short cervix reduces the risk of preterm birth and neonatal morbidity and mortality.

Vaginal morcellation: A new strategy for large gynecological malignant tumor extraction A pilot study

Objective. Evaluate feasibility and safety of a novel technique for uterine morcellation in patients scheduled for laparoscopic treatment of gynecologic malignances. Background. The laparoscopic management of uterine malignancies is progressively gaining importance and popularity over laparotomy. Nevertheless, minimal invasive surgery is of limited use when patients have enlarged uterus or narrow vagina. In these cases, conventional uterus morcellation could be a solution but should not be recommended due to risks of tumor dissemination. Methods. Prospective pilot study of women with endometrial cancer in which uterus removal was a realistic concern due to both organ size and proportionality. Brief technique description: after completion of total laparoscopic hysterectomy and bilateral anexectomy, a nylon with polyurethane Lapsac (R) is vaginally inserted into the abdomen; the specimen is placed inside the pouch that will be closed and rotated 180 degrees toward the vaginal vault and, posteriorly, pushed into the vaginal canal; in the transvaginal phase, the surgeon pulls the edges of the bag up to vaginal introitus and all vaginal walls will be covered; inside the pouch, the operator performs a uterus bisection-morcellation. Results. In our series of 8 cases, we achieved successful completion in all patients, without conversion to laparotomy. Average operative time, blood loss and length of hospitalization were favorable. One patient presented with a vesicovaginal fistula. Conclusion. The vaginal morcellation following oncologic principles is a feasible method that permits a rapid uterine extraction and may avoid a number of unnecessary laparotomies. Further studies are needed to confirm the oncological safety of the technique. (C) 2012 Elsevier Inc. All rights reserved.

How should bladder wall thickness be measured? A comparison of vaginal, perineal and abdominal ultrasound

Measurement of bladder wall thickness using transvaginal ultrasound has previously been shown to discriminate between women with diagnosed detrusor overactivity and those with urodynamic stress incontinence. So far, no comparison has been made between abdominal, perineal and vaginal route for the measurement of bladder wall thickness. The aim of this prospective study was to determine if abdominal, perineal and vaginal ultrasound measurements of bladder wall thickness are comparable with each other.

[Torsion of a pedunculated subserous myoma - a rare differential diagnosis of the acute abdomen]

We report about a rare case of acute abdomen in a 43 years old female patient who noticed a sudden onset of severe lower abdominal pain, increasing in strength within a few hours. The transabdominal and transvaginal ultrasound showed an enlarged leiomyomatous uterus with a questionable torsion of a pedunculated subserous leiomyoma. The following magnetic resonance imaging confirms this diagnosis. During the laparoscopy a myomectomy has been performed.

Injury of the corona mortis during vaginal tape insertion (TVT-Secur™ using the U-Approach)

We report a serious bleeding complication due to injury of the corona mortis following insertion of a transvaginal tape, TVT-Secur™ (Ethicon Women's Health, Sommerville, NJ, USA).

[Sarcomas and mixed mesodermal tumors of the uterus]

Malignant mesodermal tumors of the uterus are an inhomogenous group of uterine malignancies with different pathogenesis, clinical presentation and prognosis. These rare tumors represent approximately 1 % of all uterine malignancies. The aggressive carcinosarcomas or mixed muellerian tumors are defined by mixed malignant epithelial and malignant mesodermal histopathology and are of the same precursor cell origin like endometrial cancer. Thus, carcinosarcomas were reclassified by the FIGO as an aggressive type of endometrial cancer and treated like type II endometrial cancer. Adenosarcomas are also mixed tumors with benign epithelial proliferation and malignant mesodermal cell growth, have a good prognosis and represent less than 5 % of all mesodermal uterine malignancies. Besides carcinosarcomas, the pure mesodermal leiomyosarcomas are the most common mesodermal malignancies. Patients with leiomyosarcamos are usually perimenopausal, and although more than half of the patients present with symptoms, diagnosis occurs incidentally in most cases in final histopathologic workup of an excised putative myoma or uterus. Adequate anamnesis, gynecologic examination and careful imaging by transvaginal ultrasound in the preoperative setting might hint to correct differential diagnosis in many cases. Overall the prognosis of uterine leiomyomas is poor. Malignancies of the endometrial stroma are very rare and divided in two subgroups, the mostly estrogen receptor positive endometrial stromal sarcoma, which occur preferably in premenopausal women and show a favorable prognosis, and the very aggressive undifferentiated endometrial sarcomas. The more rare undifferentiated endometrial sarcomas occur in postmenopausal women and most patients die in the first two years after diagnosis. Risk stratification of preoperative differential diagnosis requires improvements and the correct histopathologic workup of mesodermal uterine malignancies is still a challenge for pathologists.

Sexual function after vaginal and abdominal fistula repair

OBJECTIVE The purpose of this study was to compare clinical outcomes and sexual function between transvaginal and transabdominal repairs of vesicovaginal fistulae (VVF). STUDY DESIGN Participants (99 women with VVF at a tertiary referral center) were treated with urinary catheterization for 12 weeks and, if the procedure was unsuccessful, underwent repair either the transvaginal (Latzko) or transabdominal technique. Objective clinical parameters were analyzed; subjective outcomes were recorded prospectively at the 6-month follow-up examination with the use of the female sexual function index to evaluate sexual function and the visual analogue scale to measure general disturbance by the fistula. RESULTS After bladder drainage for 12 weeks, 8 patients had spontaneous fistula closure. Demographic variables were similar in the transvaginal (n = 60) and transabdominal (n = 31) repair groups. The transvaginal procedure showed significantly shorter operation times, less blood loss, and shorter hospital stay. Continence rates 6 months after surgery were 82% (transvaginal) and 90% (transabdominal). Sexual function in the 64 sexually active patients was significantly improved, and overall disturbance by the fistula was reduced with both operative techniques. Neither surgical intervention was superior to the other regarding any domain of sexual function or visual analog scale. CONCLUSION Fistula repair improves sexual function and quality of life with no difference attributable to surgical route. Given this and that operating time, blood loss and length of stay are less with the transvaginal approach, the transvaginal approach is preferred in VVF repair if fistula and patient characteristics are suitable.

The Rendez-vous technique for treatment of caesarean scar defects: a novel combined endoscopic approach.

BACKGROUND A caesarean scar defect is a late complication of caesarean birth with a wide range of prevalence between 56 and 84 % depending on which diagnostic tool and which definition is used [1]. The referred symptoms which include postmenstrual spotting and infertility are fortunately rare. Moreover, severe complications such as caesarean scar pregnancy and uterine rupture in the following pregnancy may occur. Given the increasing incidence of caesarean births, the potential morbidity associated with caesarean scars is likely to become more important. Recently, a few repair techniques were described in the literature including the hysteroscopic resection of scarred tissue or the laparoscopic repair with or without robotic assistance [2, 3]. METHODS Between June 2009 and February 2014, 21 women with caesarean scar defects were operated with the Rendez-vous technique, a minimally invasive surgery combining the laparoscopic and hysteroscopic approach. Data were retrospectively collected. The indications for this surgery included secondary infertility, previous caesarean scar pregnancy, recurrent miscarriage and postmenstrual spotting. Prior to operation, a transvaginal ultrasound was performed to examine the uterine wall defect. RESULTS The patient characteristics are provided in Table 1. In all cases, the operation was successfully completed laparoscopically. The median operation time was 125 min. One case was complicated by recurrence of the scar defect 6 weeks after the operation. No other intra- or post-operative complications were observed, and the median in-patient stay was 3 days. CONCLUSIONS The benefits of the technique include the feasibility and safety of the procedure, the "Halloween sign" (Fig. 1) which indicates the exact extent and localization of the scar defect and the immediate assessment of repair through the hysteroscopy at the end of the surgery. However, before further studies evaluate the efficacy of this method, the routine repair of caesarean scar defects cannot be recommended. A video of the technique is presented.
