13. Estudo comparativo da ablação endometrial por balão térmico e sistema intra-uterino de liberação de Levonorgestrel no tratamento do sangramento uterino anormal
Introduction: Abnormal uterine bleeding affects 22% of women in menacme and near 20.000 are submitted to histerectomy each year in USA due to menorrhagia. The aim of this study is to compare the use of the levonorgestrel intrauterine system (LNG-IUS) and the thermal balloon ablation (TB) for the treatment of AUB. Methods: prospective randomised trial envolvi

14. First trimester fetal echocardiography / Ecocardiografia fetal no primeiro trimestre da gestação
Os objetivos deste estudo foram determinar o índice sucesso na realização de um ecocardiograma fetal completo entre a 11ª e a 14ª semanas, estabelecer a semana mais adequada para a realização de um exame completo, mensurar os diâmetros dos anéis das valvas cardíacas e comparar os diâmetros obtidos com o comprimento crânio-nádegas (CCN) correlaci

15. Relation of cervical length at 22-24 weeks of gestation to demographic characteristics and obstetric history
Preterm delivery is the main cause of neonatal death and ultrasonographic cervical assessment has been shown to be more accurate than digital examination in recognizing a short cervix. This is a cross-sectional study, involving 1131 women at 22-24 weeks of pregnancy, designed to determine the distribution of cervical length and to examine which variables of

16. Ultrasound-guided intra-uterine injection technique for embryo transfer in mares / Técnica ultra-sonográfica de injeção intra-uterina para transferência de embriões em eqüinos
Embryo transfer (ET) in mares has been performed by transcervical or surgical methods. Pregnancy rates resulting from the transcervical method are more variable; however this is the more routine ET technique used nowadays. The surgical method has resulted in higher and less variable pregnancy rates. Although, this technique is much more invasive than the tra

17. Anatomical and echocardiographic correlates of normal cardiac morphology in the late first trimester fetus.
OBJECTIVES: To describe the normal cardiac morphology as seen by transvaginal ultrasound imaging in the first trimester fetus and to compare it with the morphology of the heart as seen by microdissection at the same gestational age. DESIGN: In 53 mothers undergoing early sonography, the fetal heart was examined and the images recorded. The gestational age ra

18. Endometrial ossification in a postmenopausal woman.
A case of endometrial ossification in a 62 year old woman is reported. The patient presented with increased vaginal discharge. On transvaginal ultrasonography, a hyperechoic area within the uterine cavity, suggestive of an intrauterine foreign body, was noted. Histological examination of the endometrial curettage showed mature bone with neutrophilic infiltra

19. Concentrations of vitamins A and E in amniotic fluid, extraembryonic coelomic fluid, and maternal serum in the first trimester of pregnancy.
Paired samples of amniotic fluid and coelomic fluid were obtained by transvaginal ultrasound guided amniocentesis from 15 women with an ultrasonographically normal pregnancy between 8 and 12 weeks' gestation. Vitamins A and E were measured in the two pregnancy fluids and in maternal serum by high performance liquid chromatography with detection by ultraviole

20. A renin secreting ovarian steroid cell tumour associated with secondary polycythaemia.
A 67-year-old woman presented with dry skin, facial hair, hoarse voice, and weight gain. She was hypertensive (168/ 96 mm Hg), her haemoglobin concentration was 19 g/l, and haematocrit was 55.7%. The diagnosis of probable secondary polycythaemia was made. Blood testosterone concentration was 44 nmol/l (normal < 5) and was not suppressed by dexamethasone, sug

21. Advances in fetal echocardiography.
Fetal echocardiography is the primary modality for defining and evaluating fetal cardiac status and requires detailed analysis of the cardiac anatomy from numerous views and Doppler interrogation of the intracardiac structures, great vessels, and umbilical artery. Referrals for fetal echocardiography are determined by fetal, maternal, or familial risk factor
