diagnostic criteria for first trimester failing pregnancy

Maowen Hu, Liina Poder, Roy A Filly
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 on the number of additional follow-up sonograms these changes would engender. METHODS: A retrospective study of all first-trimester sonograms in women with first trimester bleeding from 1999 to 2008 was conducted...

BACKGROUND: A logistic regression model (M4) was developed in the UK to predict the outcome for women with a pregnancy of unknown location (PUL) based on the initial two human chorionic gonadotrophin (hCG) values, 48 h apart. The purpose of this paper was to assess the utility of this model to predict the outcome for a woman (PUL) in a US population. METHODS: Diagnostic variables included log-transformed serum hCG average of two measurements, and linear and quadratic hCG ratios...

BACKGROUND: The aim of this study was to generate and evaluate a new protocol that defined non-viability in the pregnancy of unknown location (PUL) population and therefore ensured no viable intra-uterine pregnancy (IUP) would be interrupted if uterine curettage was performed. A secondary aim was to evaluate published biochemical criteria that define non-viability in a PUL population to establish if these criteria could result in inadvertent termination of pregnancy (TOP) if uterine curettage was performed...

OBJECTIVE: To determine the frequency, severity, prognosis, and patterns of carpal tunnel syndrome (CTS) in pregnancy. DESIGN: Descriptive retrospective chart review using the Rochester Epidemiology Project medical record diagnostic indexing system to identify patients with new CTS occurring during pregnancy from 1987 to 1992 at our institution. SETTING: Obstetrical practice, where two thirds of pregnant women in the county receive primary obstetrical care...
