OBJECTIVE: To compare the accuracy of an immunoassay to measure levels of placental alpha-microglobulin-1 in cervicovaginal secretions with that of conventional clinical assessment for the diagnosis of rupture of membranes. METHODS: A prospective observational study was performed in consecutive patients with signs or symptoms of rupture of membranes at Seoul National University Hospital from March 2005 to February 2006. Initial evaluation included both the standard clinical evaluation for ruptur

Triple-negative breast cancer (TNBC) is sometimes mistaken for fibroadenoma due to its tendency to show benign morphology on breast ultrasound (US) albeit its aggressive nature. This study aims to develop a radiomics score based on US texture analysis for differential diagnosis between TNBC and fibroadenoma, and to evaluate its diagnostic performance compared with pathologic results. We retrospectively included 715 pathology-proven fibroadenomas and 186 pathology-proven TNBCs which were examined

OBJECTIVE: Funisitis is the histologic counterpart of the fetal inflammatory response syndrome, which is a multisystemic disorder associated with impending preterm delivery and adverse neonatal outcome. The purpose of this study was to examine the relationship between funisitis and the microbiologic status of amniotic fluid (AF) and AF white blood cell (WBC) count in patients at term. METHODS: The relationship between the presence of funisitis, AF culture, and AF WBC count was examined in 832 co

An abrupt increase in AF PG concentrations (25-fold for PGF2a) occurs before the onset of spontaneous labor at term in humans; these observations suggest that PGs increase prior to the onset of labor and contradict the claim that an increase in PG concentrations is the consequence of labor.

AF PGF2a concentrations were determined by ELISA in 140 singleton pregnancies with preterm premature rupture of membranes (PROM) (< or =35 weeks). AF was cultured for aerobic and anaerobic bacteria, and genital mycoplasmas. Intra-amniotic inflammation was defined as an elevated AF matrix metalloproteinase-8 concentration (>23 ng/ml). Results. (1) Patients with intra-amniotic inflammation and a negative AF culture had a significantly higher median AF PGF2a than those without intra-amniotic inflam

Euryale ferox has been widely used in traditional oriental medicine to treat a variety of illness. However, very little is known about the cellular actions by which this plant mediates its therapeutic effects. Various aspects of antioxidant activity were evaluated in total extracts and fractions derived from Euryale ferox. Total extracts (IC50 5.6 microg/ml) showed relatively high level radical scavenging activity toward 1, 1-diphenyl-2-picrylhydrazyl (DPPH) and also enhanced viability of Chines

Oligohydramnios was more frequent in patients with culture-proven AF infection than in those with intra-amniotic inflammation and a negative AF culture.

OBJECTIVE: This study was performed to evaluate the relationship among the Nugent score for the diagnosis of bacterial vaginosis (BV), the results of vaginal fluid culture for genital mycoplasmas, and the subsequent occurrence of preterm birth. METHODS: The Nugent score and culture for genital mycoplasmas were performed in vaginal fluid obtained from 977 pregnant women (gestational age 13-30 weeks). Vaginal samples were obtained with sterile cotton swabs. The relationship among the Nugent score,

The mechanisms underlying cervical insufficiency, a cause of spontaneous second-trimester abortion and early preterm birth, remain poorly understood. There is, however, evidence that amniotic fluid (AF) infection is a key factor in pregnancy outcomes and postoperative complications. This study was an attempt to determine the frequency and clinical importance of intraamniotic inflammation in 52 patients with acute cervical insufficiency, defined as cervical dilation of 1.5 cm or more. The patient

<b>BACKGROUND.</b> Screening mammography has decreased performance in patients with dense breasts. Supplementary screening ultrasound is a recommended option in such patients, although it has yielded mixed results in prior investigations. <b>OBJECTIVE.</b> The purpose of this article is to compare the performance characteristics of screening mammography alone, standalone artificial intelligence (AI), ultrasound alone, and mammography in combination with AI and/or ultrasound in patients with dens
