STUDY QUESTION Is there an association between discordance in embryonic growth and fetal loss at the time of the 11-14-week scan in twin pregnancies? SUMMARY ANSWER Regardless of the chorionicity, crown rump length (CRL) discordance at 7(+0)-9(+6) weeks is predictive of subsequent single fetal demise in the first trimester. WHAT IS KNOWN ALREADY Previous small studies have reported a variab...

INTRODUCTION Precise knowledge of the anatomy and development of the airways in the fetus is needed for advances in neonatal medicine. The aim of this study was to assess the morphometry of the larynx during fetal development. MATERIAL AND METHODS The study was performed on 47 human fetal larynges (27 male and 20 female) collected between the age of 13-27 weeks of intrauterine life according ...

With the use of conventional anatomical dissection, radiography, digital and statistical analysis, morphometry and skeletopy of the pancreas was carried out in 60 human foetuses of both sexes (28 female, 32 male) between the 17th and 40th week of intrauterine life. The material was fixed in a 10% formalin solution. The age of the foetuses was determined by crown-rump (CR) length measurement on ...

OBJECTIVES New early first-trimester diagnostic criteria for nonviable pregnancy recommended by the Society of Radiologists in Ultrasound via a multispecialty consensus panel extended the diagnostic size criteria of crown-rump length from 5 to 7 mm for embryos without a heartbeat and mean sac diameter from 16 to 25 mm for "empty" sacs. Our study assessed the potential impact of the new criteria...

OBJECTIVES To evaluate in a national standardised setting whether the performance of ultrasound dating during the first rather than the second trimester of pregnancy had consequences regarding the definition of pre- and post-term birth rates. METHODS A cohort study of 8,551 singleton pregnancies with spontaneous delivery was performed from 2006 to 2012 at Copenhagen University Hospital, Holbæ...
