AIM: To assess the quality of mean uterine artery pulsatility index (UtAPI) measurement in a first trimester pre-eclampsia screening program. METHODS: Consecutive patients attending first trimester screening for fetal chromosomal abnormalities also had combined screening for pre-eclampsia based on the Fetal Medicine Foundation (FMF) algorithm, in a large practice in Sydney, Australia, from May 2014 to February 2017. Distributions of mean UtAPI multiples of the median (MoM) on the logarithmic scale were plotted in relation to the normal median with 95% confidence interval (CI) for each operator and for each month...

Tributyltin chloride (TBT) is an obesogen associated with various metabolic and reproductive dysfunctions after in utero exposure. However, few studies have evaluated TBT's obesogenic effect on adult ovaries. In this study, we assessed whether TBT's obesogenic effects resulted in adult ovarian adipogenesis and other reproductive abnormalities. TBT was administered to adult female Wistar rats, and their reproductive tract morphophysiology was assessed. We further assessed the ovarian mRNA/protein expression of genes that regulate adipogenesis...

A 41-yr-old lady with abnormal uterine bleeding underwent total abdominal hysterectomy. Histologic assessment revealed an endometrial stromal sarcoma (ESS) with minimal cytologic atypia and low mitotic count (up to 7/10 high-power fields) with only focal myxoid areas, morphologically corresponding to a low-grade ESS. Immunohistochemical stains showed cyclin D1 and CD10 positivity, and negative staining for CD117 and progesterone receptor. This tumor was clinically aggressive and recurred 6 mo later. The patient died 19 mo following initial diagnosis...

Abnormal inflammatory bias in the maternal-fetal interface leads to reproductive failure in mammals. Placental exosomes are involved in maternal-fetal communication during pregnancy. However, whether the placenta or fetus is involved in regulating the balance of uterine local inflammation through exosomes remains unclear, and the mechanism must be further explored. Here we demonstrated that placenta-specific exosomes are abundant in the peripheral blood of dairy cows during early pregnancy and selectively load miRNAs, such as bta-miR-499...

An 11-year-old female Sheltie was presented with inappetence and a progressive increase in abdominal distention. Abdominal ultrasound revealed a large cystic mass in the midabdomen and cystic lesions in the right liver lobe and in the caudal pole of the left kidney. Histopathologic examination of the resected tissue revealed a myelolipoma of the spleen, dispersed splenic tissue in the liver and dispersed uterine and salpinx tissues in the kidney. This report describes the clinical, ultrasonographic and computed tomographic features and the results of histopathology...

Preeclampsia is one of the most frequent and difficult illnesses in pregnancy, which jeopardizes both mother and fetus. There are several diagnostic criteria for preeclampsia. However, the preeclampsia-associated myocardial damage has not been described. In this study, we employed reduced uterine perfusion pressure (RUPP) to generate a rat model of preeclampsia for the evaluation of myocardial damage in late-gestation rats. The expressions of cardiac injury markers were analyzed by immunohistochemistry and ELISA...

Metastasis of non-gynaecological tumours to the cervix is a rare event, and metastasis from breast cancer is even rarer, with only a limited number of such cases reported in the literature to date. We herein report the case of an 86-year-old female patient who had undergone mastectomy and axillary lymphadenectomy for invasive ductal cell breast carcinoma 2 years prior, followed by adjuvant hormonal therapy with letrozole. During hospitalization for anemia associated with an inflammatory syndrome and abdominal pain with menorrhagia, an abdominal ultrasound examination revealed a suspicious uterine mass with irregular contours and abnormal vascularization with associated increase of the blood level of cancer antigen 15-3 to 34 kU/l...

Cesarean scar pregnancy (CSP) is a rare kind of ectopic pregnancy implanted in the previous cesarean scar and has an increasing incidence over the past 30 years. As the suspicion is low, the diagnosis may be delayed or misinterpreted in ultrasound, leading to treatment strategies that might end up in uterine rupture or hysterectomy. The objective here is to review the ultrasound findings in CSP with varied presentations. Transabdominal and transvaginal sonography combined with color Doppler is a reliable tool for the diagnosis of CSP...

Developmental exposure to estrogenic chemicals is an established risk factor for cancer of the female reproductive tract. This increase in risk has been associated with disruption of normal patterns of cellular differentiation during critical stages of morphogenesis. The goal of this study was to document uterine epithelial phenotypes over time following neonatal treatment with the synthetic estrogen diethylstilbestrol (DES) or the soy phytoestrogen genistein (GEN) in female CD-1 mice. Both DES and GEN induced three distinct populations of abnormal endometrial epithelial cells: luminal (SIX1+/P63-/CK14-/CK18+), basal (SIX1+/P63+/CK14+/CK18-), and mixed/bipotential (SIX1+/P63-/CK14+/CK18+), which were all established by early adulthood...

PURPOSE OF REVIEW: To review recent findings related to possible causes of recurrent implantation failure of endometrial origin in normal uterus. RECENT FINDINGS: Recent evidences suggest that in apparently normal endometria, RIF may associate with molecular and functional changes in the uterus such as abnormal endometrial microbiota, including the presence of chronic endometritis, poor synchronization between the blastocyst and endometrium, and/or excessive uterine peristalsis...

INTRODUCTION: Uterine artery (UtA) Doppler indices are one of the most commonly employed screening tests for pre-eclampsia worldwide. Abnormal indices appear to result from increased uterine vascular resistance, but anatomical complexity and lack of appropriate animal models mean that little is known about the relative contribution of each of the components of the uterine vasculature to the overall UtA Doppler waveform. Previous computational models suggested that trophoblast-mediated spiral artery remodeling has a dominant effect on the UtA Doppler waveform...

The aim of the present study was to explore the possible relations of maternal serum and amniotic fluid nitric oxide (NO) and of vascular endothelial growth factor A (VEGF-A) concentrations with uterine artery Doppler indices (UtADs) in a healthy second trimester obstetric population. In this regard, the levels of NO and VEGF-A were measured in maternal sera and the amniotic fluid samples were in 36 subjects who were in their early second trimester of pregnancy. The mean levels for VEGF-A were 110.3 ± 31...

OBJECTIVE: Hysteroscopy has widely been used for diagnosis of the uterine cavity; however, target biopsy has often been difficult in part to the inherent limitations of ancillary instruments. Lin's biopsy grasper was specifically designed to work in conjunction with a flexible hysteroscope to obtain intrauterine biopsy under transabdominal sonography. Herein, we share our clinical experience in the management of endometrial abnormalities with the use of Lin's biopsy grasper during office-based hysteroscopy...

The number of pregnant women with abnormally invasive placenta (AIP) including clinical relevant placenta increta and percreta has markedly increased with a reported incidence of as high as one in 731, By 2020 in the United States, there will be an estimated 4504 new cases of AIP and 130 AIP-associated maternal deaths annually. The preoperative diagnosis and operative management of AIP is challenging. In a planned cesarean delivery, a vertical lower abdominal skin incision is widely used in order to have enough space to perform a hysterotomy above the cranial edge of the placenta to avoid significant fetal and/or maternal hemorrhage...
