Up to 86% of uterine leiomyomas harbour somatic mutations in mediator complex subunit 12 (MED12). These mutations have been associated with conventional histology, smaller tumour size, and larger number of tumours within the uterus. Prior studies, with limited sample sizes, have failed to detect associations between other clinical features and MED12 mutations. Here, we prospectively collected 763 uterine leiomyomas and the corresponding normal myometrial tissue from 244 hysterectomy patients, recorded tumour characteristics, collected clinical data from medical records, and screened the tissue samples for MED12 mutations to assess potential associations between clinical variables and mutation status...

BACKGROUND: There are conflicting results regarding tocolysis in cases of preterm premature rupture of membranes. Delaying delivery may reduce neonatal morbidity due to prematurity, allow for prenatal corticosteroids and, if necessary, in utero transfer. However, that may increase risks of maternofetal infection and its adverse consequences. OBJECTIVE: To investigate whether tocolytic therapy in cases of preterm premature rupture of membranes is associated with improved neonatal or obstetric outcomes...

Postpartum hemorrhage is common and can occur in patients without risk factors for hemorrhage. Active management of the third stage of labor should be used routinely to reduce its incidence. Use of oxytocin after delivery of the anterior shoulder is the most important and effective component of this practice. Oxytocin is more effective than misoprostol for prevention and treatment of uterine atony and has fewer adverse effects. Routine episiotomy should be avoided to decrease blood loss and the risk of anal laceration...

Acute puerperal inversion of the uterus is a rare life-threatening obstetric emergency, especially during caesarean section. We present the case of a 30-year-old patient with acute puerperal inversion of the uterus that occurred during placental removal. After a quick reversion of the uterus, an immediate postpartum haemorrhage (PPH) due to massive uterine atony was observed. This atony impacted the whole uterus, with a very thin uterine myometrium. The use of a Bakri Tamponade Balloon use allowed treating extreme uterine atony, immediately stop haemorrhage, and prevent a possible risk of immediate recurrence...

In ovine pregnancy, uterine space restriction (USR) resulting from decreased space for placental attachment caused intrauterine growth restriction and impaired nephrogenesis. The fetal kidney renin-angiotensin system (RAS) is involved in nephrogenesis, fluid balance, and iron deposition. Angiotensin II exerts its effects via multiple receptors: angiotensin II 1-8 receptor type 1 (AT 1 R) and type 2 (AT 2 R), and angiotensin II 1-7 Mas receptor (MASR). Objective: : To test the hypothesis that ovine USR is associated with dysregulation of the fetal renal RAS...

Purpose Our aim was to describe the changes observed by ultrasonography in uterine dimensions during the early puerperium among women who experienced an uncomplicated puerperium. Additionally, the influence of parity, mode of delivery, breastfeeding and birth weight on uterine involution was evaluated. Methods Ninety-one patients underwent an ultrasound examination on days 1 (D1), 2 (D2) and 7 (D7) of the postpartum period. The longitudinal, anteroposterior and transverse uterine diameters were measured, and the uterine volume was calculated by the formula: longitudinal diameter (LD) X anteroposterior diameter (APD) X transverse diameter (TD) X 0...

STUDY QUESTION: Do intraluteal prostaglandins (PG) contribute to luteal regulation in women? SUMMARY ANSWER: Prostaglandin E (PGE), which is produced in human granulosa-lutein cells stimulated with luteotropic hCG, exerts similar luteotropic effects to hCG, and the expression of PG synthetic and metabolic enzymes in the human CL is driven toward less PGE but more prostaglandin F (PGF) during luteolysis. WHAT IS KNOWN ALREADY: Uterine PGF is a major luteolysin in many non-primate species but not in women...

PURPOSE: Apparent diffusion coefficient (ADC) histogram analysis has been used to some extent in cervical cancer (CC) to distinguish between low-grade and high-grade tumors. Although this differentiation is undoubtedly helpful, it would be even more crucial in the presurgical setting to determine whether a tumor already gained the potential to metastasize via the lymphatic system. So far, no studies investigated the potential of 3T ADC histogram analysis in CC to differentiate between nodal-positive and nodal-negative entities...

BACKGROUND: Although leiomyomas are the most common gynecologic disorders, non-puerperal uterine inversion due to leiomyoma is considered as a rare clinical problem. This condition can occur as a complication of a large sub-mucous leiomyoma that leads to dilate cervix and protrude into vagina. The patient may have several symptoms such as heavy vaginal bleeding, pelvic pain and intermittent acute urinary retention. CASE: We presented a 32-year-old nulliparous woman with 17 years of unexplained infertility and diagnosis of a large vaginal prolapsed non-pedunculated leiomyoma...

OBJECTIVE: To investigate serum inflammatory markers in singleton gestations complicated with threatened preterm labour (TPL). METHODS: Pregnant women complicated with TPL (n = 61) were recruited to measure maternal serum levels of a panel of cytokines and C-reactive protein and then compared to controls without TPL, matched for gestational age (n = 64) and term pregnancies in the prodromal phase of labour (PPL) (n = 31). In addition, baseline cytokine levels were compared among cases and controls according to the outcome...

Recent evidence suggests that uterine activation for labor is associated with inflammation within uterine tissues. Hydrogen sulfide (H2S) plays a critical role in inflammatory responses in various tissues. Our previous study has shown that human myometrium produces H2S via its generating enzymes cystathionine-γ-lyase (CSE) and cystathionine-β-synthetase (CBS) during pregnancy. We therefore explored whether H2S plays a role in the maintenance of uterine quiescence during pregnancy. Human myometrial biopsies were obtained from pregnant women at term...

62 Background: Extended-duration thromboprophylaxis for 4 weeks after discharge has been demonstrated to reduce venous thromboembolic events (VTE) in cancer patients undergoing abdominopelvic surgery and is recommended in national guidelines. We examined the utilization and effectiveness of extended-duration low molecular weight heparin prophylaxis in high-risk cancer patients after surgery. METHODS: We analyzed patients with colon, ovarian, and uterine cancer who underwent surgery from 2009-2013 and who were recorded in the MarketScan database...

REVIEW
Haerani Rasyid, Syakib Bakri
Low birth weight (LBW) is defined as a birth weight of a liveborn infant of <2,500 gram. In developed countries, LBW is commonly caused by preterm birth; while in developing countries, it is mostly due to intrauterine growth retardation. The concept of developmental origins of adult diseases, particularly on late-onset diseases such as hypertension and kidney disease, implies that there is a correlation between intrauterine milieu, intrauterine growth retardation, premature birth and infant feeding. The 'fetal origin hypothesis' suggests that metabolic diseases are directly related to poor nutritional status in early life...

We present our experience of using the HDlive silhouette inversion mode to assess complete hydatidiform mole early in pregnancy. The HDlive silhouette inversion mode clearly depicted the number, size, and spatial position of molar vesicles, compared with conventional two-dimensional sonography or the HDlive inversion mode. Moreover, spatial relationships among molar vesicles, intrauterine anechoic fluid collection, and the uterine wall enabled the clear localization of the lesion. This technique provides new insights, and has the potential to supplement conventional two-dimensional sonography in the diagnosis of complete hydatidiform mole...

INTRODUCTION: Physical activity (PA) has been associated with lower risk of cardiovascular diseases, but the evidence linking PA with lower cancer risk is inconclusive. We examined the independent and interactive effects of PA and obesity using body mass index (BMI) as a proxy for obesity, on the risk of developing prostate (PC), postmenopausal breast (BC), colorectal (CRC), ovarian (OC) and uterine (UC) cancers. METHODS: We estimated odds ratios (OR) and 95% confidence intervals (CI), adjusting for cancer specific confounders, in 6831 self-reported cancer cases and 1992 self-reported cancer-free controls from the Cancer Lifestyle and Evaluation of Risk Study, using unconditional logistic regression...

We report a non-puerperal uterine inversion with nulliparous women caused by huge pedunculated submucosal fibroid. Massive bleeding from protruding mass through vagina brought the heart to stop in 42-year-old nulliparous woman. She became cardiopulmonary resuscitation survivor in emergency room and then underwent laparotomy which ended in successful myomectomy rather than hysterectomy considering her demand for future fertility. Meticulous and adequate fluid therapy and transfusion was also administered to recover from hypovolemic status...

Identification of combinatorial markers from multiple data sources is a challenging task in bioinformatics. Here we propose a novel computational framework for identifying significant combinatorial markers (SCMs) using both gene expression and methylation data. The gene expression and methylation data are integrated into a single continuous data as well as a (post-discretized) boolean data based on their intrinsic (i.e., inverse) relationship. A novel combined score of methylation and expression data (viz., CoMEx) is introduced which is computed on the integrated continuous data for identifying initial non-redundant set of genes...

Gestational trophoblastic disease (GTD) is a group of conditions that originate from the abnormal proliferation of trophoblastic cells. GTDs encompass hydatidiform moles (HMs) and gestational trophoblastic neoplasia (GTN). GTNs are a group of malignant diseases that require chemotherapy, or more aggressive treatment. There is a requirement for more tumor markers to predict the development of GTN from HMs. The current study evaluated the expression of maspin and tumor protein p53 (p53) in GTD, and their role in predicting the development of GTN...
