uterine inversion

BACKGROUND: Endometrial polyps (EPs) are one of the most common intrauterine benign tumors, and are an important cause of uterine bleeding and female infertility. Previous studies have suggested that endometritis may contribute to the onset of EPs. This study aims to reveal the causal effect of endometritis on EPs by a two-sample Mendelian randomization (MR) study. METHODS: Utilizing summarized statistics from genome-wide association studies (GWAS) in the European population, we conducted a Mendelian randomization study...

Carcinosarcoma (CS) is an aggressive form of gynecologic malignancy that accounts for ~5% of carcinomas in the endometrium and ovaries. There has been no significant improvement in survival over the last decades despite additional treatment options. PReferentially Expressed Antigen in MElanoma (PRAME) is an immunotherapy target used for the treatment of several solid tumors. We explored the PRAME protein expression levels in ovarian and uterine CS (n = 29). The expression levels were recorded by H-score (percentage of positively stained cells multiplied by staining intensity) in carcinomatous and sarcomatous components separately and compared by paired t-test...

OBJECTIVE: Few fetal malformations benefit from in utero surgery. One of the major drawbacks of fetal surgery is preterm premature rupture of membranes (PPROM). Morbidity associated with congenital diaphragmatic hernia (CDH) is primarily respiratory but also gastrointestinal and induced prematurity are likely to worsens those complications. To assess whether or not the cannula insertion site on the maternal abdomen during fetoscopic endoluminal tracheal occlusion (FETO) was associated with PPROM before balloon removal...

BACKGROUND: Personal care products (PCPs), a source of endocrine-disrupting chemical exposure, may be associated with the risk of hormone-sensitive cancers. Few studies have investigated associations for PCP use with the incidence of hormone-sensitive cancers or considered the joint effect of multiple correlated PCPs. We examined associations between frequently used, or "everyday", PCPs and incident cancers of the breast, ovary, and uterus with a fucus on the joint effect of multiple product exposure...

BACKGROUND: The World Cancer Research Fund (WCRF)/American Institute for Cancer Research (AICR) Cancer Prevention Recommendations are lifestyle-based recommendations which aim to reduce cancer risk. This study investigated associations between adherence, assessed using a standardised scoring system, and the risk of all cancers combined and of 14 cancers for which there is strong evidence for links with aspects of lifestyle in the UK. METHODS: We used data from 94,778 participants (53% female, mean age 56 years) from the UK Biobank...

INTRODUCTION: The pedunculated fibroid is classically managed through vaginal myomectomy. However, vaginal myomectomy cannot be safely and easily performed in all cases. We reviewed three cases of prolapsed pedunculated submucosal fibroids, each with a specific surgical difficulty. PRESENTATION OF CASES: The first case had a prolapsed pedunculated uterine fibroid in pregnancy and underwent fibroid extirpation during an emergency cesarean section through the lower uterine segment incision...

BACKGROUND: Cancers that primarily affect women in the US include breast, uterine, and cervical cancers. There may be associations between these different types of cancer in women and environmental pollutant exposure. PURPOSE: This study aimed to assess seven species of arsenic, six polycyclic aromatic hydrocarbon (PAH) compounds, and fourteen different metal concentrations in urine and their correlation with cancer among women. METHODS: We conducted a cross-sectional analysis using 2011-2012 to 2015-2016 National Health and Nutrition Examination Survey data (n = 4956) and logistic regression modeling of the complex weighted survey design...

There has been no previous systematic, epidemiological study of the reproductive risk factors for uterine fibroids (UF) in African populations despite African women having the highest burden of UF in the world. Improved knowledge of the associations between UF and reproductive factors would contribute to better understanding of the etiology of UF and may suggest novel opportunities for prevention and therapeutic interventions. We used nurse administered questionnaires to survey the demographic and reproductive risk factors of UF among 484 women who are members of the African Collaborative Center for Microbiome and Genomics Research (ACCME) Study Cohort in central Nigeria, and who had transvaginal ultrasound diagnosis (TVUS)...

OBJECTIVE: Cesarean hysterectomy is generally presumed to decrease maternal morbidity and mortality secondary to placenta accreta spectrum disorder. Recently, uterine-sparing techniques have been introduced in conservative management of placenta accreta spectrum disorder to preserve fertility and potentially reduce surgical complications. However, despite patients often expressing the intention for future conception, few data are available regarding the subsequent pregnancy outcomes after conservative management of placenta accreta spectrum disorder...

OBJECTIVE: To evaluate whether prophylactic administration of 1 g of intravenous calcium chloride after cord clamping reduces blood loss from uterine atony during intrapartum cesarean delivery. METHODS: This single-center, block-randomized, placebo-controlled, double-blind superiority trial compared the effects of 1 g intravenous calcium chloride with those of saline placebo control on blood loss at cesarean delivery. Parturients at 34 or more weeks of gestation requiring intrapartum cesarean delivery after oxytocin exposure in labor were enrolled...

BACKGROUND: The WCRF/AICR Cancer Prevention Recommendations are lifestyle-based guidelines which aim to reduce cancer risk. This study investigated, in the UK Biobank, associations between an abbreviated score to assess adherence to these Recommendations and the risk of all cancers combined and of 14 cancers for which there is strong evidence for links with diet, adiposity, and physical activity. METHODS: We used data from 288,802 UK Biobank participants (mean age 56...

OBJECTIVES: First, to compare the ophthalmic artery peak systolic velocity (PSV) ratio and biomarkers of impaired placentation at 36 weeks' gestation in women who delivered small for gestational age (SGA) or fetal growth restricted (FGR) neonates in the absence of hypertensive disorders with those who developed preeclampsia (PE) or gestational hypertension (GH) and those unaffected by SGA, FGR, PE or GH. Second, to examine the associations between PSV ratio, uterine artery pulsatility index (UtA-PI), placental growth factor (PlGF) and soluble fms-like tyrosine kinase-1 (sFLT-1) with birthweight z-score or percentile...

The number of cases of placenta accreta spectrum (PAS) disorder has been increasing with the increase in in-vitro fertilization and cesarean sections. In addition, PAS without placenta previa is difficult to diagnose prior to delivery and sometimes requires a hysterectomy due to heavy bleeding. We have devised a uterus-preserving technique (TURIP procedure) for such cases. First, the bleeding is stopped by the Tourniquet method, the uterus is relaxed with nitroglycerin, and the uterus is inverted to expose the adhesion site...

BACKGROUND: The administration of tocolytics after preterm prelabor rupture of membranes remains a controversial practice. In theory, reducing uterine contractility should delay delivery and allow for optimal antenatal management, thereby reducing the risks for prematurity and adverse consequences over the life course. However, tocolysis may be associated with neonatal death or long-term adverse neurodevelopmental outcomes, mainly related to prolonged fetal exposure to intrauterine infection or inflammation...

INTRODUCTION: Uterine inversion is a disease characterized by the folding of the uterine fundus into the uterine cavity or beyond the cervix. It is a rare complication following parturition. Acute uterine inversion presents immediately following vaginal delivery. Prevalence of acute uterine inversion is 1 in 20,000-50,000 cases. Chronic uterine inversion is a rare disease presentation in post-menopausal women. It is commonly associated with uterine pathology like leiomyoma, leiomyosarcoma, or endometrial polyps...

Uterine inversion occurs in puerperal and non-puerperal conditions; non-puerperal uterine inversion (NPUI) may run acute and chronic clinical course. Most on the NPUI are chronic variety while a few are acute variety. NPUI occurs if there is long standing big sub-mucosal fibroid and it is very rare to present in acute setting. Here we report a case of acutely presented NPUI. A 58-year-old widow of lower socioeconomic status presenting to the emergency center of Chittagong medical college Hospital with complaints of sudden protrusion of a big mass through introitus in an attempt of passing out hard stool during defecation on the day of admission with a history of per vaginal watery discharge for a long time and severe anemia...

Studies have suggested the potential roles of serum macronutrients such as calcium and magnesium in the development of uterine fibroids. The primary objective was to assess the association between serum magnesium and calcium levels and the prevalence of uterine fibroids in women of reproductive age. A cross-sectional study of 194 parity-matched women with or without a sonographic diagnosis of uterine fibroids enrolled at a university teaching hospital in Lagos, Southwest Nigeria. Participants' sociodemographic, ultrasound, and anthropometric information as well as the estimated serum levels of calcium and magnesium were collected for statistical analyses...

BACKGROUND: Some hormonally active cancers have low survival rates, but a large proportion of their incidence remains unexplained. Endocrine disrupting chemicals may affect hormone pathways in the pathology of these cancers. OBJECTIVE: To evaluate cross-sectional associations between per- and polyfluoroalkyl substances (PFAS), phenols, and parabens and self-reported previous cancer diagnoses in the National Health and Nutrition Examination Survey (NHANES). METHODS: We extracted concentrations of 7 PFAS and 12 phenols/parabens and self-reported diagnoses of melanoma and cancers of the thyroid, breast, ovary, uterus, and prostate in men and women (≥20 years)...

Background: Patients with advanced or recurrent endometrial cancer (EC) have limited treatment options following platinum-based chemotherapy and poor prognosis. The single-arm, Phase I GARNET trial (NCT02715284) previously reported dostarlimab efficacy in mismatch repair-deficient/microsatellite instability-high advanced or recurrent EC. Objectives: The objective of this study was to compare overall survival (OS) and describe time to treatment discontinuation (TTD) for dostarlimab (GARNET Cohort A1 safety population) with an equivalent real-world external control arm receiving non-anti-programmed death (PD)-1/PD-ligand (L)1/2 treatments (constructed using data from a nationwide electronic health record-derived de-identified database and applied GARNET eligibility criteria)...
