Uterine angioleiomyoma is rare. A 40-year-old nulliparous woman presented with heavy menstrual bleeding (HMB) for the past 2 years and mass per abdomen with severe dysmenorrhea for three cycles. She had received 8 units of packed cell transfusion outside. Clinical examination revealed a huge 32-week-sized abdominopelvic mass with irregular margins. Ultrasonography (USG) of the abdomen and pelvis showed a large solid cystic mass on the right side of the abdomen with a well-defined hypoechoeic rounded lesion of size 5...

OBJECTIVE: Women with repaired coarctation of the aorta (rCoA) are at risk of hypertensive disorders and other complications during pregnancy. Hypertensive disorders in pregnant women are associated with inadequate uteroplacental flow, which is related to adverse offspring outcome. The aim of this study was to investigate the relationship of maternal cardiac function, placental function and pregnancy complications in women with rCoA. METHODS: We included 49 pregnant women with rCoA and 69 controls from the prospective ZAHARA-studies (Zwangerschap bij Aangeboren HARtAfwijkingen, pregnancy in congenital heart disease)...

BACKGROUND: Implantation defect is one of these contributing factors for unexplained infertility. In the mid-luteal phase, when implantation is expected to happen, Integrins expression is remarkably increased. So, Integrins could potentially serve as markers for the frame of the window of implantation. αVβ3 integrin could have a role as a potential receptor for embryonic attachment. The aim of the current study is to investigate whether the women with unexplained infertility have a pattern of expression of endometrial αvβ3 integrin that could differ from those who have normal fertility or not...

Preterm infants (born at 24-34 weeks of gestational age) suffer from a high incidence of neurological complications. Cerebrovascular lesions (intraventricular hemorrhages, IVH, and ischemic injury) due to the immaturity of the vascular system and its inability to adapt to the extra-uterine environment are the major causes of adverse neurological outcomes. We investigated the feasibility of assessing cerebrovascular status in preterm infants using a novel non-invasive optical procedure, pulse-DOT, usable within the incubator...

BACKGROUND: Uterine artery pseudoaneurysm (UAP) normally presents genital bleeding in the puerperal period, and severe hydronephrosis rarely presents during pregnancy. We report a rare case of severe ureteral obstruction accompanied by uterine artery pseudoaneurysm in the early second trimester of pregnancy, which was successfully treated by surgical intervention. CASE PRESENTATION: A 42-year-old nulligravid woman who had undergone myomectomy 3 years earlier was referred to our hospital for acute left abdominal pain at the 17th week of gestation...

Various methods are being employed to detect early pregnancy in domestic animals. This study aimed to predict early pregnancy in buffaloes via measuring the corpus luteum (CL) diameter, the luteal blood flow (LBF) area, the uterine blood flow (UBF) vascularization area, and progesterones in saliva and serum for non-pregnant (NPBs, N = 12) and pregnant (PBs, N = 12) buffaloes. The results revealed that the CL diameter and the luteal color blood flow blue and red (P = 0.0001) areas of the pregnant animals kept increasing from day 1 to day 35 of the gestation period, but it decreased in NPBs on day 21 after reaching a peak from ovulation to day 18...

Purpose To investigate whether ultrasound follow-up for the detection of postpartum retained products of conception (RPOC) in women considered at risk for this condition may allow for early diagnosis. Methods Parturients at risk for RPOC underwent an ultrasound exam on the second postpartum day. Based on the ultrasound findings, women were either: (1) discharged to routine postpartum care in cases of normal scans, (2) invited for follow-up in cases of abnormal scans. We retrospectively analyzed the rates of women requiring uterine evacuation due to persistent abnormal scans...

RATIONALE: Epithelioid trophoblastic tumor (ETT) is a distinctive but rare gestational trophoblastic neoplasia (GTN) composed of chorionic-type intermediate trophoblast cells. Approximately 50% ETT arose from the uterine cervix or lower uterine segment following a previous pregnancy with vaginal bleeding. With its unusual ability to simulate an invasive epithelioid neoplasm, ETT frequently poses a diagnostic challenge, especially involving the uterine cervix. PATIENT CONCERNS: We herein report the case of a 60-year-old female with persistent vaginal bleeding and middle-level elevation of serum human chorionic gonadotropin (hCG)...

AIM: To determine whether Doppler evaluation at 20-24 weeks of gestation can predict reduced fetal size later in pregnancy or at birth. METHODS: Fetal biometry and Doppler velocimetry were performed in 2,986 women with a singleton pregnancy at 20-24 weeks of gestation. Predictive performances of the umbilical artery pulsatility index (UA-PI) or the mean uterine artery pulsatility index (UtA-PI) >95th percentile, middle cerebral artery pulsatility index, or cerebroplacental ratio (CPR) <5th percentile for early small for gestational age (SGA; <34 weeks of gestation), late SGA (≥34 weeks of gestation), or SGA at birth (birthweight <10th percentile) were analyzed...

INTRODUCTION: Increase in Nitric Oxide (NO) may be important in vascular adaptation needed to accommodate increased uteroplacental blood flow as pregnancy advances. Hence, in certain conditions like Pregnancy Induced Hypertension (PIH) and Fetal Growth Restriction (FGR), NO donors may play an effective role in increasing uteroplacental perfusion. Transdermal route appears to be a safe and effective route. AIM: To evaluate the effect of nitroglycerine patch on Doppler velocity waveforms of the uterine, umbilical and fetal middle cerebral arteries in patients with chronic placental insufficiency...

Adnexal torsion is the fifth most common gynecologic surgical emergency, requiring clinician and radiologist awareness. It involves the rotation of the ovarian tissue on its vascular pedicle leading to stromal edema, hemorrhagic infarction, and necrosis of the adnexal structures with the subsequent sequelae. Expedient diagnosis poses a difficult challenge because the clinical presentation is variable and often misleading. Adnexal torsion can mimic malignancy as it can take a subacute, intermittent, or chronic course, and thereby can be complicated to diagnose...
