Vasoactive Intestinal Peptide and Its Receptors in Human Ovarian Cortical Follicles

BACKGROUND: Ovarian cryopreservation is one option for fertility preservation in patients with cancer. The danger of reseeding malignancies could be eliminated by in vitro maturation of primordial follicles from the frozen-thawed tissue. However, the development of this system is hindered by uncertainties regarding factors that activate primordial follicles. Neuronal growth factors such as vasoactive intestinal peptide (VIP) play important roles in early mammalian folliculogenesis. There are no data on the expression of VIP and its vasoactive intestinal peptide pituitary adenylate cyclase 1 and 2 receptors (VPAC1-R and VPAC2-R) in human preantral follicles. METHODOLOGY/PRINCIPAL FINDINGS: Tissue samples from 14 human fetal ovaries and 40 ovaries from girls/women were prepared to test for the expression of VIP, VPAC1-R, and VPAC2-R on the protein (immunohistochemisty) and mRNA (reverse transcription polymerase chain reaction) levels. Immunohistochemistry staining was mostly weak, especially in fetal samples. The VIP protein was identified in oocytes and granulosa cells (GCs) in the fetal samples from 22 gestational weeks (GW) onwards. In girls/women, VIP follicular staining (oocytes and GCs) was identified in 45% of samples. VPAC1-R protein was identified in follicles in all fetal samples from 22GW onwards and in 63% of the samples from girls/women (GC staining only in 40%). VPAC2-R protein was identified in follicles in 33% of fetal samples and 47% of the samples from girls/women. The mRNA transcripts for VIP, VPAC1-R, and VPAC2-R were identified in ovarian extracts from fetuses and women. CONCLUSIONS: VIP and its two receptors are expressed in human ovarian preantral follicles. However, their weak staining suggests they have limited roles in early follicular growth. To elucidate if VIP activates human primordial follicles, it should be added to the culture medium

Vaginal wind – a new pelvic symptom

The aim of this study was to evaluate the risk factors, investigations and treatments for vaginal wind. A prospective longitudinal study was carried out at a tertiary care referral centre at St George’s Hospital, London. Six consecutive women with symptomatic vaginal air were enrolled in the study, which used a comprehensive questionnaire for vaginal air, prolapse, urinary, bowel and sexual symptoms, vaginal examination following the Standardized ICS Scoring System for prolapse, physiotherapist evaluation, and analysis of the treatment. Main outcome measureswere the effect of the patient’s age, weight, parity, mode of delivery, fetal weight, and the treatment (conservative and surgical) on the frequency of vaginal wind. The mean age of the six women was 32.8±9.9 years (range 21–52), the mean BMI was 23.1±5.5 (range 15.2–32.2), all women were premenopausal and five were parous. The mean estimated frequency of the symptoms was 20.0±8.1 per day (range 10–40). All the patients completed a course of pelvic floor physiotherapy and one patient had a posterior repair and later a Fenton operation without improvement. A modified ‘Bard’ pessary was the main form of treatment and resolved the symptoms in two women. Vaginal wind causes significant distress and embarrassment to sufferers. Further information on risk factors, evaluation and treatment modalities should be obtained

How accurate is preoperative evaluation of pelvic organ prolapse in women undergoing vaginal reconstruction surgery?

OBJECTIVE: To evaluate the differences between the in-office and intraoperative techniques used to evaluate pelvic organ prolapse. MATERIALS AND METHODS: A prospective study included 25 women undergoing vaginal reconstruction surgery including vaginal hysterectomy for pelvic organ prolapse. The outpatient pelvic and site-specific vaginal examination was performed in the lithotomy position with the Valsalva maneuver. Repeated intraoperative examination was performed under general anesthesia with standard mild cervical traction. The Pelvic Organ Prolapse Quantification system (POPQ) was used for both measurements and staging. The values found under the two conditions were compared. RESULTS: The intraoperative POPQ-measurements values were significantly higher than the outpatient values for apical wall prolapse in 17/25 (68%) women and for anterior wall prolapse in 8/25 (32%) women. There was not a significant difference in the posterior wall where increase in staging was shown in 3/25 (12%) patients. CONCLUSIONS: Clinicians and patients should be alert to the possibility that pelvic organ measurements performed under general anesthesia with mild traction may be different from preoperative evaluation

Epidural analgesia associations with depression, PTSD, and bonding at 2 months postpartum

The research aim was to study the possible effect of epidural analgesia, as well as other possible demographic/obstetric variables and subjective birth experience on postpartum depression, PTSD, and impaired bonding. This was a longitudinal study of 254 women who gave birth at the maternity wards of a large tertiary health center and responded to questionnaires at T1 (Childbirth Experience Questionnaire and level of fatigue question; in person, 1–4 days postpartum) and at T2 (Postnatal Depression Scale, Postpartum Bonding Questionnaire, and the City Birth Trauma Scale; online-two months postpartum). Obstetric and demographic data were taken from medical files. Having a previous psychiatric diagnosis and higher levels of fatigue significantly predicted worse outcomes in all measures (level of fatigue was not associated with the City Birth Trauma birth-related symptoms factor). Having higher education, being primiparous, worse birth experience, and longer second stage of birth predicted worse outcomes in some measures. Although epidural administration had no effect on any of the outcome variables, special attention should be devoted to women who had long second-stage births and/or suffering from postpartum fatigue to prevent postpartum psychopathology. In addition, demographic variables, such as primiparity, education, and prior psychopathology diagnosis should be considered to treat women and prevent postpartum psychopathology

The “Pelvic Harness”: a skeletonized mesh implant for safe pelvic floor reconstruction

ABSTRACT Objectives To evaluate the feasibility, safety and surgical results of skeletonized mesh implants to form a pelvic harness for pelvic floor reconstruction surgery. Study design Patients with advanced pelvic floor prolapse were enrolled to this study. Study model was a kit mesh, reduced to 75% of the original surface area by cutting out mesh material from the central mesh body. Patients were evaluated at the end of the 1st and 6th post-operative months and interviewed at the study conclusion. Results Ninety-five women with advanced pelvic floor prolapse had this implant. Mean follow-up duration was 9 months (6-12 months). The POP-Q point’s measurements showed marked and statistically significant improvements. Bladder over-activity symptoms, fecal incontinence, pelvic pain and constipation rates were all reduced as well. No adverse effects related to the dissection or mesh implantation were marked. The first and sixth post-operative month follow-up records as well as the study conclusion interview findings were satisfactory in terms of subjective and objective cure and adverse effects occurrence. Conclusion This study data proposes that skeletonizing meshes might be safely and successfully implanted for potentially improved pelvic floor reconstruction

Clinical course of patients treated for advanced ovarian carcinoma without surgical intervention.

OBJECTIVE: To describe the clinical course and outcome of patients with non-surgically-treated advanced ovarian cancer attending a single institute. METHODOLOGY/PRINCIPAL FINDINGS: We reviewed the medical charts of all patients with advanced epithelial ovarian cancer who underwent chemotherapy at a tertiary medical center between January 2005 and December 2010 but were never operated. Data on patient characteristics, disease course, and outcome were collected from patient files. Sixteen patients met the inclusion criteria. Eight (50%) were diagnosed with apparent FIGO stage IIIC disease, and 8 with stage IV. Five patients (31%) achieved a complete clinical response, and 11 (69%) achieved a partial response. Among the complete responders, the median disease-free interval was 8 months (range 7-11 months). In all of them, the disease recurred and second-line chemotherapy was administered. Of them, four (80%) achieved a second complete response. Partial responders had up to four lines of chemotherapy, with continued disease progression. The median overall survival of the whole group was 19.5 months, and of the complete responders, 28 months. CONCLUSIONS/SIGNIFICANCE: Most patients with advanced ovarian carcinoma who will not undergo surgery respond only partially to first-line chemotherapy. Having no surgery is associated with a short disease-free interval

Indications for Emergency Intervention, Mode of Delivery, and the Childbirth Experience.

Although the impact of emergency procedures on the childbirth experience has been studied extensively, a possible association of childbirth experience with indications for emergency interventions has not been reported.To compare the impacts on childbirth experience of 'planned' delivery (elective cesarean section and vaginal delivery) versus 'unplanned' delivery (vacuum extraction or emergency cesarean section); the intervention itself (vacuum extraction versus emergency cesarean section); and indications for intervention (arrest of labor versus risk to the mother or fetus).A total of 469 women, up to 72 hours post-partum, in the maternity ward of one tertiary health care institute completed the Subjective Childbirth Experience Questionnaire (score: 0-4, a higher score indicated a more negative experience) and a Personal Information Questionnaire. Intra-partum information was retrieved from the medical records. One-way analysis of variance and two-way analysis of variance, followed by analysis of covariance, to test the unique contribution of variables, were used to examine differences between groups in outcome. Tukey's Post-Hoc analysis was used when appropriate.Planned delivery, either vaginal or elective cesarean section, was associated with a more positive experience than unplanned delivery, either vacuum or emergency cesarean section (mean respective Subjective Childbirth Experience scores: 1.58 and 1.49 vs. 2.02 and 2.07, P <0.01). The difference in mean Subjective Childbirth Experience scores following elective cesarean section and vaginal delivery was not significant; nor was the difference following vacuum extraction and emergency cesarean section. Interventions due to immediate risk to mother or fetus resulted in a more positive birth experience than interventions due to arrest of labor (Subjective Childbirth Experience: 1.9 vs. 2.2, P <0.01).Compared to planned interventions, unplanned interventions were shown to be associated with a more negative maternal childbirth experience. However, the indication for unplanned intervention appears to have a greater effect than the nature of the intervention on the birth experience. Women who underwent emergency interventions due to delay of birth (arrest of labor) perceived their birth experience more negatively than those who underwent interventions due to risk for the mother or fetus, regardless of the nature of the intervention (vacuum or emergency cesarean section). The results indicate the importance of follow-up after unexpected emergency interventions, especially following arrest of labor, as negative birth experience may have repercussions in a woman's psychosocial life and well-being
