OBJECTIVE This study aimed to survey the current clinical practice of first-trimester ultrasonography among members of the Korean Society of Ultrasound in Obstetrics and Gynecology (KSUOG) and to provide basic data for making practical recommendations about first-trimester ultrasonography scan in Korea. METHODS This survey was conducted using a self-administered anonymous questionnaire. The f...

(1) Approximately three in every four fetuses with Down syndrome have increased nuchal translucency (NT), which is a larger than normal build-up of fluid at the back of the neck. (2) The ultrasound measurement of NT between 11 and 14 weeks' gestation, in combination with the mother's age and the levels of placental biochemical markers in her blood, can be used to detect approximately 84% of fet...

introduction: topographic anatomy of the tendons and ligaments in healthy cases provides a normal atlas to diagnose abnormalities. the aim of this study was to provide ultrasonography description of the palmar tendons and ligaments of the anatoly donkey. methods: the metacarpal regions of 6 healthy anatoly donkeys were prepared for ultrasonography and divided to 6 levels (1a, 1b, 2a, 2b, 3a, 3b...

INTRODUCTION Numerous papers have proven that an increased nuchal translucency is connected with a raised risk of chromosomal aberrations, but few analyses are related to the further state of fetuses with a normal karyotype. THE AIM OF THE STUDY The aim of the study was to estimate the risk of cardiac defects and other developmental disorders in fetuses with increased nuchal translucency and ...

Cranial base morphology differs among hominoids in ways that are usually attributed to some combination of an enlarged brain, retracted face and upright locomotion in humans. The human foramen magnum is anteriorly inclined and, with the occipital condyles, is forwardly located on a broad, short and flexed basicranium; the petrous elements are coronally rotated; the glenoid region is topographic...

In a study of 50 cases of trisomy 18 compared with 947 controls we have found the median multiple of the median (MoM) of maternal serum free human chorionic gonadotrophin to be significantly decreased (0.281 MoM) in samples collected between the 10th and 14th week of gestation. Similarly, maternal serum pregnancy associated plasma protein A (PAPP-A) levels are also decreased (0.177 MoM), whilst...

OBJECTIVE To compare the effects, safety, and cost effectiveness of antenatal screening strategies for Down's syndrome. DESIGN Analysis of incremental cost effectiveness. SETTING United Kingdom. MAIN OUTCOME MEASURES Number of liveborn babies with Down's syndrome, miscarriages due to chorionic villus sampling or amniocentesis, health care costs of screening programme, and additional costs...

Paramaldane, new genus, with type species Paramaldane glandicincta sp. n., and Maldane adunca sp. n. (Maldanidae, Polychaeta) are described based on material from the coast of south China. The new genus Paramaldane is similar to Maldane Grube, 1860 and Sabaco Kinberg, 1867, but it clearly differs from all genera within the subfamily Maldaninae by a unique combination of characters: the cephalic...
