Repurposing of Bryophyllum pinnatum for dysmenorrhea treatment: a systematic scoping review and case series.

Dysmenorrhea affects women throughout their reproductive years but there has been a lack of effective and well-tolerated treatment options. Pain symptoms mainly result from inflammatory processes and increased contractile activity in the myometrium. The reported use of Bryophyllum pinnatum preparations against inflammation and pain in ethnomedicine as well as current pharmacological data on their inhibition of myometrial contractility led us to hypothesize that this medicinal plant might be a new treatment option for dysmenorrhea. In the first part of the present work, clinical, in vivo, and in vitro studies on the anti-nociceptive and anti-inflammatory, as well as on myometrium relaxing properties of B. pinnatum are reviewed. In the second part, cases of five women with dysmenorrhea who were tentatively treated with a B. pinnatum product are described. The review revealed thirty-three experimental in vivo and in vitro studies, but no clinical study, reporting anti-nociceptive and anti-inflammatory effects of B. pinnatum extracts and compounds in a wide range of conditions. Moreover, sixteen publications on smooth muscle contractility revealed relaxing effects. The latter consisted of clinical evidence, as well as of in vivo and in vitro data. The evidence reviewed therefore provided a rational basis for the use of B. pinnatum in the treatment of dysmenorrhea. We subsequently set out to tentatively treat patients with a well-tolerated B. pinnatum product that is registered (without indication) and commonly used in obstetrics and gynecology in Switzerland. All five treated patients reported a reduction in pain symptoms and 4 out of 5 indicated a reduced intake of painkillers during menstruation. Taken together, the reviewed information on the pharmacological properties and clinical evidence of B. pinnatum extracts and compounds as well as the outcomes of all five patients in the case series support our hypothesis in favor of B. pinnatum as a new, well-tolerated therapeutic approach for dysmenorrhea. Prospective clinical studies are urgently needed.

Hypertensive disorders of pregnancy share common cfDNA methylation profiles.

Hypertensive disorders of pregnancy (HDP) contribute substantially to perinatal morbidity and mortality. Epigenetic changes point towards cardio-metabolic dysregulation for these vascular disorders. In early pregnancy, epigenetic changes using cell free DNA (cfDNA) are largely unexplored. We aimed to investigate these in HDP between 11 and 14 weeks of gestation by analysis of cfDNA methylation profiles in patients with hypertensive disorders. We identified patients without chronic hypertension but with subsequent development of preeclampsia (PE) (n = 11), with chronic hypertension (HT) but without PE development (n = 14), and lacking both PE and HT (n = 422). We matched patients according to PE risk factors into three groups (n = 5 each group): (1) PE: no HT but PE development, (2) HT: chronic hypertension but no PE and (3) Control: no PE or HT. We successfully optimized our cfDNA isolation process prior to whole genome bisulfite sequencing. Analysis of cfDNA methylation changes indicate a common predisposition in PE and HT groups, chiefly of maternal origin. Assessment of significant differentially methylated regions and annotated genes point towards a common cardiovascular predisposition in preeclampsia and hypertension groups in the first trimester. We postulate the pivotal role of the maternal cardiovascular system in HDP, which is already evident in the first trimester.

Preimplantation factor modulates oligodendrocytes by H19-induced demethylation of NCOR2.

Failed or altered gliogenesis is a major characteristic of diffuse white matter injury in survivors of premature birth. The developmentally regulated long noncoding RNA (lncRNA) H19 inhibits S-adenosylhomocysteine hydrolase (SAHH) and contributes to methylation of diverse cellular components, such as DNA, RNA, proteins, lipids, and neurotransmitters. We showed that the pregnancy-derived synthetic PreImplantation Factor (sPIF) induces expression of the nuclear receptor corepressor 2 (NCOR2) via H19/SAHH-mediated DNA demethylation. In turn, NCOR2 affects oligodendrocyte differentiation markers. Accordingly, after hypoxic-ischemic brain injury in rodents, myelin protection and oligodendrocytes' fate are in part modulated by sPIF and H19. Our results revealed an unexpected mechanism of the H19/SAHH axis underlying myelin preservation during brain recovery and its use in treating neurodegenerative diseases can be envisioned.

Synthetic PreImplantation Factor (sPIF) reduces inflammation and prevents preterm birth.

Preterm birth (PTB) is the leading cause of neonatal morbidity and mortality and spontaneous PTB is a major contributor. The preceding inflammation/infection contributes not only to spontaneous PTB but is associated with neonatal morbidities including impaired brain development. Therefore, control of exaggerated immune response during pregnancy is an attractive strategy. A potential candidate is synthetic PreImplantation Factor (sPIF) as sPIF prevents inflammatory induced fetal loss and has neuroprotective properties. Here, we tested maternal sPIF prophylaxis in pregnant mice subjected to a lipopolysaccharides (LPS) insult, which results in PTB. Additionally, we evaluated sPIF effects in placental and microglial cell lines. Maternal sPIF application reduced the LPS induced PTB rate significantly. Consequently, sPIF reduced microglial activation (Iba-1 positive cells) and preserved neuronal migration (Cux-2 positive cells) in fetal brains. In fetal brain lysates sPIF decreased IL-6 and INFγ concentrations. In-vitro, sPIF reduced Iba1 and TNFα expression in microglial cells and reduced the expression of pro-apoptotic (Bad and Bax) and inflammatory (IL-6 and NLRP4) genes in placental cell lines. Together, maternal sPIF prophylaxis prevents PTB in part by controlling exaggerated immune response. Given the sPIF`FDA Fast Track approval in non-pregnant subjects, we envision sPIF therapy in pregnancy.

The Interplay Between Reproductive Tract Microbiota and Immunological System in Human Reproduction.

In the last decade, the microbiota, i.e., combined populations of microorganisms living inside and on the surface of the human body, has increasingly attracted attention of researchers in the medical field. Indeed, since the completion of the Human Microbiome Project, insight and interest in the role of microbiota in health and disease, also through study of its combined genomes, the microbiome, has been steadily expanding. One less explored field of microbiome research has been the female reproductive tract. Research mainly from the past decade suggests that microbial communities residing in the reproductive tract represent a large proportion of the female microbial network and appear to be involved in reproductive failure and pregnancy complications. Microbiome research is facing technological and methodological challenges, as detection techniques and analysis methods are far from being standardized. A further hurdle is understanding the complex host-microbiota interaction and the confounding effect of a multitude of constitutional and environmental factors. A key regulator of this interaction is the maternal immune system that, during the peri-conceptional stage and even more so during pregnancy, undergoes considerable modulation. This review aims to summarize the current literature on reproductive tract microbiota describing the composition of microbiota in different anatomical locations (vagina, cervix, endometrium, and placenta). We also discuss putative mechanisms of interaction between such microbial communities and various aspects of the immune system, with a focus on the characteristic immunological changes during normal pregnancy. Furthermore, we discuss how abnormal microbiota composition, "dysbiosis," is linked to a spectrum of clinical disorders related to the female reproductive system and how the maternal immune system is involved. Finally, based on the data presented in this review, the future perspectives in diagnostic approaches, research directions and therapeutic opportunities are explored.

Placental mesenchymal dysplasia: An underdiagnosed placental pathology with various clinical outcomes.

BACKGROUND: Placental mesenchymal dysplasia (PMD) is a rare vascular and connective placental anomaly, which is often associated with severe fetal and/or maternal complications. The diversity of presentation of PMD challenges diagnosis and effective pregnancy management. OBJECTIVE: We aimed to review cases presenting at 7 tertiary centers worldwide over the last decade and to study the occurrence of obstetric and neonatal complications. STUDY DESIGN: Pathology databases from 7 tertiary hospitals were screened for cases of PMD (between 2007-2017). Pregnancy history, outcomes and ultrasound images were then reviewed for each case. RESULTS: Twenty-two cases of PMD were identified. Mean gestational age at diagnosis was 23 weeks (16-39 weeks). Prenatal biochemical screening was abnormal in 8 cases (36%). Of the 12 cases that underwent invasive genetic testing, 4 were abnormal. Six patients (27%) developed maternal complications (preeclampsia/gestational hypertension). Fetal growth restriction was identified in 11 cases (50%) and fetal death in 4 (18%). Four (18%) pregnancies were terminated, 9/14 (64%) delivered preterm and only three (14%) progressed normally. Fourteen babies were born alive; 5 (35%) died in the first sixty-one days after birth, 5 (35%) had transient thrombopenia and 1 (7%) had developmental delay at last follow-up. Our series identified four potential new associations with PMD: placental triploidy mosaicism, CHARGE syndrome, fetal pleuropulmonary blastoma and fetal skeletal dysplasia. CONCLUSIONS: PMD was substantially under-diagnosed before delivery in this cohort. Sonographers, fetal medicine specialists, obstetricians and pathologists should all suspect PMD in cases of an enlarged placenta and should look for fetal abnormalities. Diagnostic genetic testing should be discussed to exclude partial molar pregnancy. Close pregnancy follow-up is indicated due to the high risk of associated fetal or maternal adverse outcomes.

Nomograms of the Fetal Sylvian Fissure and Insular Lobe throughout Gestation: A Multicentric, Ultrasonographic Cross-Sectional Study.

INTRODUCTION: Anomalies in cortical development are often associated with an adverse outcome, but prenatal diagnosis is often impeded by the limited knowledge about normal sulci biometries throughout fetal brain development. Our aim was to provide two-dimensional ultrasonographical (2D US) nomograms of the depth of the Sylvian fissure (SF) and insular lobe (IL), as well as of the SF ratio throughout gestation in a large number of fetuses. MATERIALS AND METHODS: This was a prospective cross-sectional study of 329 normal singleton pregnancies. Measurements of the SF, IL, and SF ratio were obtained in a standard transthalamic plane of the fetal head. The SF ratio was defined as SF\SF + IL. All measurements were expressed by regression equations as a function of gestational age (GA) according to the method described by Royston and Wright. The first 38 measurements were repeated twice by 2 examiners to assess the reproducibility through the intraclass correlation coefficient (ICC). RESULTS: A significant correlation was found between GA and SF (r = 0.79; p < 0.0001) as well as IL (r = 0.77; p < 0.0001). Similarly, the SF ratio also showed a significant correlation with GA (r = 0.39; p < 0.0001). When interobserver variability was assessed, ICC was 0.97. CONCLUSIONS: Prenatal 2D US measurements of SF and IL as well as the SF ratio may be feasible and reproducible using a standard view of the fetal head. Our nomograms may be used as a reference for assessing cortical development throughout pregnancy.

The Vermian-Crest Angle: A New Method to Assess Fetal Vermis Position within the Posterior Fossa Using 3-Dimensional Multiplanar Sonography.

BACKGROUND: Normal morphometry of the vermis and its relation to the posterior fossa (PF) rule out most major anomalies of the cerebellum. However, accurate categorization of the position and size of the fetal vermis remains a challenge. OBJECTIVE: Our aim was to test a new method to assess the position and size of fetal vermis on 3-dimensional ultrasound (3D-US). METHODS: We measured the vermian-crest angle (VCA) in normal fetuses using multiplanar 3D-US. We also assessed the diameters (superoinferior, anteroposterior, and horizontal) and volume of the vermis. The Spearman rank test and linear and polynomial regression analyses were used for statistical purposes. RESULTS: We included 126 fetuses. Mean ± SD gestational age (GA) was 26.3 ± 4.6 (range 17-35.5) weeks. Mean ± SD superoinferior, anteroposterior, and horizontal diameters were 16.2 ± 4.9, 11.2 ± 3.6, and 5.6 ± 1.6 mm, respectively. Median (range) vermian volume was 0.50 (0.05-2.9) cm3. The VCA was 64.49° ± 11.45. We found no correlation between GA and VCA (r = 0.15; p = 0.13), a linear correlation between GA and vermian diameters, and a quadratic correlation between GA and vermian volume. CONCLUSIONS: We provide a new method to assess vermian position and size within the PF using 3D-US. The combined information may be of value for screening purposes, particularly to differentiate between the various pathological situations encountered within the PF.

The core sequence of PIF competes for insulin/amyloid ß in insulin degrading enzyme: potential treatment for Alzheimer's disease.

The central pathological feature of Alzheimer's disease (AD) is the sequential proteolytic processing of amyloid precursor protein (APP) to amyloid-ß peptides (Aß) agglomeration. The clearance of Aß may be induced by the large zinc-binding protease insulin degrading enzyme (IDE). IDE is the common link between AD and Type II diabetes as insulin is an IDE target as well. Not surprisingly, the search for safe and effective drugs modulating IDE is ongoing. A new pregnancy derived peptide, PreImplantation Factor (PIF), inhibits neuro-inflammation and crosses the blood-brain-barrier. Importantly, we report that the (R3I4K5P6) core sequence of the PIF peptide modulates IDE function and results in decreased Aß agglomeration in neuronal cells. Using bioinformatics we show that PIF binds to the IDE complex and sterically competes for the same place as insulin or Aß. The predicted RIKP sequence and especially the specific I4 and P6 amino acids are essential for hydrophobic interactions with the IDE complex. In terms of potential AD treatment, PIF was successfully tested in neurodegenerative animal models of perinatal brain injury and experimental autoimmune encephalitis. Importantly, sPIF received a FDA Fast Track Approval and orphan drug designation for first-in-human trial in autoimmunity.

Extracellular Vesicles Derived from Wharton's Jelly Mesenchymal Stem Cells Prevent and Resolve Programmed Cell Death Mediated by Perinatal Hypoxia-Ischemia in Neuronal Cells.

Hypoxic-ischemic (HI) insult in the perinatal phase harbors a high risk of encephalopathy in the neonate. Brain cells undergo apoptosis, initiating neurodegeneration. So far, therapeutic approaches such as cooling remain limited. Transplantation of mesenchymal stem cells (MSCs) exhibits therapeutic success despite the short-time survival in the host brain, providing strong evidence that their beneficial effects are largely based on secreted factors, including extracellular vesicles (EVs). The aim of this study was to investigate the effects of human Wharton's jelly MSC (hWJ-MSC)-derived EVs on neuroprotection and neuroregeneration, using an in vitro model of oxygen-glucose deprivation/reoxygenation (OGD/R) mimicking HI injury in the mouse neuroblastoma cell line neuro2a (N2a). hWJ-MSC-derived EVs were isolated from cell culture supernatants by multistep centrifugation and identified by endosomal marker expression and electron microscopy. OGD/R significantly increased DNA fragmentation and caspase 3 ( Casp3) transcription in N2a cells relative to undamaged cells. OGD/R-mediated DNA fragmentation and Casp3 expression could be prevented as well as resolved by the addition of hWJ-MSC-derived EV before and after OGD, respectively. hWJ-MSC-derived EV also tended to increase the phosphorylation of the B cell lymphoma 2 (Bcl2) family member Bcl-2-antagonist of cell death (BAD) in N2a cells, when added prior or post OGD, thereby inactivating the proapoptotic function of BAD. Fluorescence confocal microscopy revealed the close localization of hWJ-MSC-derived EVs to the nuclei of N2a cells. Furthermore, EVs released their RNA content into the cells. The expression levels of the microRNAs (miRs) let-7a and let-7e, known regulators of Casp3, were inversely correlated to Casp3. Our data suggest that hWJ-MSC-derived EVs have the potential to prevent and resolve HI-induced apoptosis in neuronal cells in the immature neonatal brain. Their antiapoptotic effect seems to be mediated by the transfer of EV-derived let-7-5p miR.

Reference Ranges for Fetal Atrioventricular and Ventriculoatrial Time Intervals and Their Ratios during Normal Pregnancy.

BACKGROUND: The diagnostic assessment of fetal arrhythmias relies on the measurements of atrioventricular (AV) and ventriculoatrial (VA) time intervals. Pulsed Doppler over in- and outflow of the left ventricle and tissue Doppler imaging are well-described methods, while Doppler measurements between the left brachiocephalic vein and the aortic arch are less investigated. The aim of this study was to compare these methods of measurement, to find influencing factors on AV and VA times and their ratio, and to create reference ranges. METHODS: Echocardiography was performed between 16 and 40 weeks of gestation in normal singleton pregnancies. Nomograms for the individual measurements were created using quantile regression with Matlab Data Analytics. Statistical analyses were performed with GraphPad version 5.0 for Windows. RESULTS: A total of 329 pregnant women were enrolled. A significant correlation exists between AV and VA times and gestational age (GA) (p = 0.0104 to <0.0001, σ = 0.1412 to 0.3632). No correlation was found between the AV:VA ratio and GA (p = 0.08 to 0.60). All measurements differed significantly amongst the studied methods (p < 0.0001). CONCLUSIONS: AV and VA intervals increase proportionally with GA; no other independent influencing factors could be identified. As significant differences exist between the three methods of assessment, it is crucial to use appropriate reference ranges to diagnose pathologies.

Efficacy of hysteroscopy in improving reproductive outcomes of infertile couples: a systematic review and meta-analysis.

BACKGROUND: The scientific community has been re-evaluating the clinical relevance of hysteroscopy in the diagnosis and treatment of uterine factors and its role in the infertility work-up, thanks to its potential capability to improve reproductive outcomes and reduce time to pregnancy. OBJECTIVE AND RATIONALE: The objective of this systematic review and meta-analysis was to assess the efficacy of diagnostic and operative hysteroscopy in improving the live birth rate (LBR) of infertile women, with and without intrauterine abnormalities, at any stage of the infertility work-up. SEARCH METHODS: PubMed, Embase, the Cochrane Library and the Clinical Trials Registry using Medical Subject Headings and free text terms were searched up to June 2014, without language or year restrictions. Randomized controlled trials (RCTs) enrolling infertile women with no suspected intrauterine cavity abnormalities and comparing hysteroscopy versus no hysteroscopy at any stage of the diagnostic work-up, but prior to the first attempt of standard IVF or ICSI or after (one or more) failed attempts of IVF/ICSI were included. RCTs enrolling infertile women with intrauterine abnormalities and comparing operative versus diagnostic hysteroscopy were also included. Risk of bias was assessed using the criteria recommended by the Cochrane Collaboration and the overall quality of evidence was assessed using the GRADE approach. Results were pooled by meta-analysis using the random effect model. OUTCOMES: The primary outcome evaluated was the LBR, while secondary outcomes were pregnancy rate, miscarriage rate and procedure-related complications. Five hundred and eighty-eight records were retrieved after removing duplicates. Nine studies were included, with 2976 participants. Four studies included infertile women with one or more failed IVF/ICSI cycles. Two studies included infertile women who were candidates for their first IVF/ICSI. One study included candidates both for first IVF/ICSI and with one or more failed IVF/ICSI cycles. Two studies included infertile women affected by uterine fibroids and endometrial polyps, who had not received IVF/ICSI nor were candidates. Seven studies were included in the meta-analysis. Comparing hysteroscopy with no hysteroscopy prior to any (first or subsequent) IVF/ICSI attempt in infertile women without intrauterine abnormalities, there was very low-quality evidence that hysteroscopy increased LBR (relative risk (RR) 1.48, 95% confidence interval (CI) 1.20-1.81; three studies with 1088 participants) and moderate quality evidence that it increased pregnancy rate (RR 1.45, 95% CI 1.26-1.67; seven studies, 2545 participants). Results on pregnancy rate were confirmed in the subgroup analysis of five studies including only women with one or more implantation failures (RR 1.41, 95% CI 1.14-1.75) and three studies where hysteroscopy was performed before the first IVF/ICSI attempt (RR 1.55, 95% CI 1.26-1.91). Comparing operative hysteroscopy for intrauterine abnormalities in infertile women with already diagnosed polyps or fibroids, there was low-quality evidence that operative hysteroscopy increases pregnancy rate (RR 2.13, 95% CI 1.56-2.92). None of the studies comparing operative versus diagnostic hysteroscopy assessed LBR. WIDER IMPLICATIONS: Robust and high-quality RCTs are still needed before hysteroscopy can be regarded as a first-line procedure in all infertile women, especially during the basal clinical assessment of the couple, when assisted reproductive treatment is not indicated yet.

Challenging the cervix: strategies to overcome the anatomic impediments to hysteroscopy: analysis of 31,052 office hysteroscopies.

OBJECTIVE: To report our experience on 10,156 cases of cervical stenosis (CS) diagnosed at office hysteroscopy. DESIGN: Retrospective study. SETTING: Ambulatory clinics of diagnostic and operative hysteroscopy of two university teaching hospitals (Naples and Bari). PATIENT(S): A total of 31,052 patients undergoing office hysteroscopy. INTERVENTION(S): All of the paper and electronic reports of the office hysteroscopies performed from January 1996 to September 2014 were reviewed. Hysteroscopies were classified as successful (i.e., when access to and visualization of the entire uterine cavity was possible during the same procedure), incomplete (i.e., when access to uterine cavity was possible, but the entire uterine cavity could not be examined), or failed (i.e., when access to uterine cavity was not possible). CS was classified on the basis of localization: stenosis of external cervical ostium (ECO; type I); stenosis of distal third of cervical channel and the internal cervical ostium (ICO; type II); stenosis of the ICO (type III), and combined stenosis of ECO and ICO (type IV). MAIN OUTCOME MEASURE(S): The success rate at overpassing CS (including both successful and incomplete hysteroscopies) was the primary outcome measure. Secondary outcome measures were frequency and localization of CS in fertile and postmenopausal women and the frequency of use of technical maneuvers and/or miniaturized mechanical or bipolar instruments to overcome them. RESULT(S): All hysteroscopies were performed with the use of a 5- or 4-mm rigid continuous-flow office operative hysteroscope by operators with different levels of expertise. The hysteroscopy technique used was standardized between the two centers and among all of the surgeons throughout the years. An access to the uterine cavity with a complete evaluation of the whole endometrial surface was possible in 93.9% of cases (29,152 patients). The main reasons of the 1,320 (4.3%) incomplete and 580 (1.9%) failed hysteroscopies were pain and CS, respectively. CS was identified in 10,156 women (32.7% of all procedures) and was significantly more frequent in postmenopausal than in fertile women (70.1% vs. 29.9%), except for type I stenosis, which was more frequent in fertile than in postmenopausal women. Type IV CS (44.3%) was the most commonly detected. Overall, CS was managed successfully with minimal discomfort in 98.5% of cases with technical maneuvers and miniaturized mechanical and/or bipolar instruments. Adhesiolysis with the distal tip of the hysteroscope by rotating the scope on the endocamera was the significantly more used strategy to overpass all types of CS (39.8% of cases), generally used in combination with miniaturized operative instruments (79.2%). Bipolar electrodes were more used in cases of type I and type IV stenosis (39.7%) compared with the other types of CS. CONCLUSION(S): CS and pain represent the main reasons for failed hysteroscopy. Recent technical and technologic innovations, together with increased operator experience and optimal pain management, have made it possible to overcome even severe CS with the use of office hysterosocpy, thus significantly reducing the rate of failed procedures and the need for operating room and general anesthesia.

Hysteroscopic treatment of Müllerian duct anomalies.

Müllerian duct anomalies are a broad and complex spectrum of abnormalities that are often associated with infertility, obstetric complications as well as gynecological disorders among women of reproductive age. Operative hysteroscopy is the gold standard in the treatment of most of those anomalies amenable to surgical correction. The evidence to date shows an ongoing increase in the release of recommendations in favour of operative hysteroscopic treatment, in concert with the progressive refinement of hysteroscopic technologies and techniques. The aim of this paper was to describe and critically evaluate the role of the currently available hysteroscopic techniques for treating Müllerian duct anomalies, taking into account their indications, feasibility and efficacy as well as their impact on the reproductive outcome. Special attention will be paid to the most recently developed minimally invasive treatments for uterine and vaginal anomalies.

Ambulatory management of heavy menstrual bleeding.

Heavy menstrual bleeding (HMB) has significant adverse effects on the quality of life of many women, placing an economic burden on both health services and society at large. Thus, it is essential that all women with HMB have easy access to the proper diagnostic and therapeutic work-up in an outpatient fashion, avoiding the more time-consuming inpatient management. This new outpatient approach for HMB is one of the latest development of gynecological practice and can offer both diagnostic and therapeutic procedures. This manuscript aims to show the current possibilities of the modern management of HMB, which can be safely and effectively accomplished in the outpatient setting: global and directed endometrial biopsy, levonorgestrel intrauterine system insertion as well as minimally invasive surgical procedures (encompassing a variety of operative hysteroscopic procedures and second-generation endometrial ablation) are described below.

The Challenge of Prenatal Diagnostic Work-Up of Maternally Inherited X-Linked Opitz G/BBB: Case Report and Literature Review.

Background. Prenatal diagnosis of Optiz G/BBB syndrome (OS) is challenging because the characteristic clinical features, such as facial and genitourinary anomalies, may be subtle at sonography and rather unspecific. Furthermore, molecular testing of the disease gene is not routinely performed, unless a specific diagnosis is suggested. Method. Both familial and ultrasound data were used to achieve the diagnosis of X-linked OS (XLOS), which was confirmed by molecular testing of MID1 gene (Xp22.3) at birth. Results. Sequencing of MID1 gene disclosed the nucleotide change c.1285 +1 G>T, previously associated with XLOS. Conclusions. This case illustrates current challenges of the prenatal diagnostic work-up of XLOS and exemplifies how clinical investigation, including family history, and accurate US foetal investigations can lead to the correct diagnosis.

The potential role of endometrial nerve fibers in the pathogenesis of pain during endometrial biopsy at office hysteroscopy.

We aimed to evaluate whether nerve fibers are present in the endometrial layer of patients submitted to office hysteroscopy and their potential contribution to the pathogenesis of pain during that procedure. Through a prospective case-control study performed in tertiary centers for women's health, endometrium samples were collected during operative office hysteroscopy from 198 cycling women who previously underwent laparoscopy and/or magnetic resonance imaging investigation for infertility assessment. Samples were classified according to the degree of the pain patients experienced and scored from values ranging from 0 (absence of discomfort/pain) to 10 (intolerable pain) on a 10-cm visual analog scale (VAS). The presence of nerve fiber markers (S100, NSE, SP, VIP, NPY, NKA, NKB, NKR1, NKR2, and NKR3) in the endometrium was also evaluated by morphologic and immunohistochemical analyses. We found that S-100, NSE, NKR1, NK-A, NK-B, VIP, and NPY, were immunolocalized in samples of endometrium, in significantly (P < .01, for all) higher levels in samples collected from patients with VAS score > 5 (group A) than ≤ 5 (group B) and significantly (P < .0001 for all) positively correlated with VAS levels. A statistically significant (P = .018) higher prevalence of endometriosis and/or adenomyosis was depicted in patients of group A than group B. Data from the present study led us to conclude that nerve fibers are expressed at the level of the functional layer of the endometrium and may contribute to pain generation during office hysteroscopy, mainly in women affected by endometriosis and adenomyosis.

Pentalogy of Cantrell: embryofetoscopic diagnosis.

Embryofetoscopy is an endoscopic technique that permits a direct visualization and morphologic study of embryos during the first and early second trimester. We report the early prenatal diagnosis of a case of Pentalogy of Cantrell combining data obtained by 2-dimensional and 3-dimensional ultrasonography and embryofetoscopy. Morphologic examination focused on a large omphalocele protruding from the anterior abdominal wall as an oval pulsating mass, measuring approximately 3 cm. The visualization of an omphalocele with ectopia cordis without other malformations confirmed the diagnosis of Pentalogy of Cantrell (class III). Currently, embryofetoscopy allows direct visualization of the embryo in vivo, enabling accurate diagnosis of developmental defects and yielding additional insights into developmental disorders in the embryo.

Hysteroscopic findings in women with menorrhagia.

STUDY OBJECTIVE: To describe the hysteroscopic findings in patients complaining of menorrhagia to establish any significant association between menorrhagia and benign/malignant intrauterine disorders. DESIGN: Prospective cohort study (Canadian Task Force classification II). SETTING: University La Sapienza, Rome, Italy. PATIENTS: One hundred eighteen premenopausal women undergoing office hysteroscopy for menorrhagia (group A) and 344 premenopausal patients undergoing office hysteroscopy for other indications (noncyclic abnormal uterine bleeding, infertility, ultrasonographic abnormalities, etc) (group B). INTERVENTIONS: Office hysteroscopy. MEASUREMENT AND MAIN RESULTS: Data on the prevalence of hysteroscopic findings (cervical polyps, endometrial polyps, submucous myomas, low-grade hyperplasia and high-grade hyperplasia/endometrial carcinoma) were compared between group A and group B. The total prevalence, as well as the prevalence of type 0 and type I myomas (totally or >50% intracavitary, respectively), and the mean number per patients with submucous myomas was significantly higher in group A compared with group B (p = .0001, p = .024, and p = .017, respectively). Multivariable logistic regression analysis showed a statistically significant association between age (odds ratio 4.15, 95% confidence interval 1.55-11.1 in the 40- to 49-year age group), presence of submucous myomas (odds ratio 2.76, 95% confidence interval 1.52-5.00), and menorrhagia. CONCLUSIONS: Menorrhagia seems to be associated with aging, the presence and number of submucous myomas, and with the degree of their intracavitary development.
