Foetal axillary lymphangioma with ipsilateral pes equinovarus: pitfalls in sonographic differential diagnosis (axillary lymphangioma & pes equinovarus).

Lymphangiomas are rare congenital malformations of the lymphatic system. Despite the benign histology, they are likely to grow rapidly and invade the surrounding tissues. In contrast to the cystic hygromas, lymphangiomas at the axillary region tend to have normal karyotype.

De novo reciprocal translocation t(5;11)(q22;p15) associated with hydrops fetalis (reciprocal translocation and hydrops fetalis).

Objective: This is a case of a prenatally diagnosed non-immune hydrops fetalis (NIHF) associated with translocation t(5;11)(q22;p15). An association between NIHF and this translocation has not been reported previously.

Case Report: The patient was referred to the perinatology clinic with hydrops fetalis diagnosis at 23 weeks' gestation.

Ductus Venosus Doppler Flow Velocity after Transplacental and Non-transplacental Amniocentesis during Midtrimester.

Objective: We aimed to evaluate ductus venosus Doppler waveforms before and after amniocentesis in order to investigate any effect of amniocentesis on fetal myocardial hemodynamics. We also evaluated the umbilical artery, uterine artery and fetal mid-cerebral artery Doppler waveforms in order to investigate any relationship with ductus venosus Doppler changes.

Methods: The study population consisted of 56 singleton pregnancies having genetic amniocentesis.

The assessment of placental volume and mean gray value in preeclamptic placentas by using three-dimensional ultrasonography.

Objectives: We aimed to evaluate the placental volume and placental mean gray value in preeclampsia and healthy placentas by using three-dimensional (3D) ultrasonography and Virtual Organ Computer-aided AnaLysis (VOCAL).

Methods: This case-control prospective study consisted of 27 singleton pregnancies complicated by preeclampsia and 54 healthy singleton pregnancies matched for gestational age, maternal age and parity. Placental volume and placental volumetric mean gray values were evaluated.

Prenatal administration of granulocyte-macrophage colony-stimulating factor increases mesenchymal vascular endothelial growth factor expression and maturation in fetal rat lung.

The aim of this study was to determine influence of prenatal granulocyte-macrophage colony-stimulating factor (GM-CSF) administration on lung growth, maturation, and vascular endothelial growth factor (VEGF) expression. Twenty Wistar rats received sterile saline (1 mL) or recombinant human GM-CSF (50 micro g/kg) on day 16 of pregnancy. Rats were sacrificed on days 18 and 20 of gestation.

Pelvic floor function and anatomy after childbirth.

Objective: To investigate pelvic floor muscle function and anatomy after childbirth in continent women differing in obstetric history.

Study Design: Young, continent women, age range 20-40 years, were recruited into 3 groups: 1. elective, prelabor cesarean delivery (n =12); 2.

Antenatal administration of granulocyte-macrophage colony-stimulating factor increases fetal lung maturation and endothelial nitric oxide synthase expression in the fetal rat lung.

Objectives: We investigated how maternal administration of granulocyte-macrophage colony-stimulating factor (GM-CSF) induced fetal lung maturation compared with dexamethasone and whether maternal administration of GM-CSF and dexamethasone influenced the fetal lung eNOS expression.

Study Design: Thirty pregnant rats were divided into three groups of 10 rats each to receive GM-CSF, dexamethasone or saline solution at 16 days of gestation. Lung maturation using bronchial area and immunohistochemical lung airway epithelium and the vascular endothelial eNOS expression, using H Scores, were evaluated at 18 and 20 days of gestation.

A comparative study of the effect of raloxifene and gosereline on uterine leiomyoma volume changes and estrogen receptor, progesterone receptor, bcl-2 and p53 expression immunohistochemically in premenopausal women.

Objective: To compare the mechanism of action of raloxifene and gosereline induced shrinkage of leiomyomas via estrogen receptor, progesterone receptor, bcl-2 and p53 expression immunohistochemically.

Study Design: Thirty-two premenopausal women affected by uterine leiomyomas were randomized into two equal groups. Group A was treated with gosereline (3.

Hormone receptor expressions and proliferation markers in postmenopausal endometrial polyps.

Background/aims: Endometrial polyps are quite common in the general population, they have a significant role in postmenopausal bleeding, and the pathogenesis is unclear. The aim of this study was to investigate proliferation markers and expression of estrogen and progesterone receptors in endometrial polyps in postmenopausal women.

Endometrial thickness and the Doppler sonographic parameters of the uterine arteries as discriminators of endometrial status in postmenopausal women receiving anti-hypertensive treatment.

Aim: The aim of the present study was to establish the Doppler sonographic parameters of the uterine arteries in postmenopausal patients with or without hypertension and to determine the value of their measurement in the prediction of endometrial pathology.

Methods: Healthy postmenopausal women (n = 23) and the ones receiving anti-hypertensive medication (n = 34) examined for both endometrial thickness and Doppler velocimetry of the uterine arteries by transvaginal sonography.

Results: There was no significant difference between endometrial thickness and uterine artery Doppler sonographic parameters in hypertensive postmenopausal women compared to normotensive controls.

Fetal intra-abdominal umbilical vein dilatation associated with notching in umbilical artery.

Introduction: Dilatation of the fetal intra-abdominal umbilical vein is a rare entity. It is unclear whether prenatally diagnosed umbilical vein dilatation is associated with an increased risk of fetal anomalies or poor perinatal outcome. Umbilical artery waveform notching may be a predictor of cord abnormalities.
