Counts of Fasciola spp. eggs in faeces and measurements of antibody concentration to the excretory/secretory antigens of Fasciola spp. by ELISA were related to the numbers of flukes in the livers of 92 cattle killed in the abattoirs of Hanoi City, Vietnam. In this population, about 22% of the cattle had no flukes, another 22% had between 1 and 10 flukes,(More)
OBJECTIVE The purpose of this study was to compare the usefulness of renal sonograms obtained 6 days and 6 weeks after birth in differentiating obstruction from nonobstruction in patients with antenatal pyelocaliceal dilatation shown by sonography and to establish sonographic criteria to determine the degree of postnatal pyelocaliceal dilatation that(More)
Abstract Background. Fluoroscopic micturating cystourethrography (MCU) is used for screening and grading of vesicoureteral reflux (VUR). It involves ionizing radiation. This study was designed to assess the efficacy of contrast-enhanced sonography in predicting the presence or absence of VUR. Objective. To compare an ultrasound contrast agent for detection(More)
OBJECTIVE Diastematomyelia is a form of spinal dysraphia involving a sagittal cleft in the spinal cord with splaying of the posterior spinal elements. This may be an isolated abnormality or in association with more serious dysraphic conditions. In isolated diastematomyelia, the skin is intact and the prognosis excellent. This study aimed to determine the(More)
OBJECTIVE The goal of our study was to analyze the fetal renal pelvic diameters measured sonographically at several gestational intervals in live-born neonates subsequently found to have either obstructive uropathy or normal kidneys. This information will improve the efficacy of sonography in the diagnosis of obstructive uropathy. SUBJECTS AND METHODS(More)
OBJECTIVE Postnatal investigation of mild degrees of fetal hydronephrosis has allowed subsequent detection of infants with vesicoureteric reflux (VUR). This study was designed to provide short to medium term information on such infants who had primary VUR, the rates of renal damage and progression over time, the risk factors for such damage and to compare(More)
OBJECTIVE There is an urgent need for a bedside method to assess the effectiveness of neonatal therapies designed to improve cerebral development in very low birth-weight infants. The aim of this study was to assess the impact of preterm birth on the serial growth of the corpus callosum and how soon it could be detected after birth with cranial ultrasound.(More)
The energy spectrum of X-ray photons after passage through an absorber contains information about its elemental composition. Thus, tissue characterisation becomes feasible provided that absorption characteristics can be measured or differentiated. Dual-energy CT uses two X-ray spectra enabling material differentiation by analysing material-dependent(More)
BACKGROUND AND PURPOSE It is desirable to develop a bedside method for assessing cerebral development in the very premature infant to monitor the effectiveness of interventions aimed at improving cerebral development. Our aim was to describe the growth trajectory of the corpus callosum (CC) on cranial sonography in very premature infants. METHODS We(More)
Prognosis of the very low birth weight infant depends more on gestational age than birth weight, but clinical assessment of gestational age of very low birth weight infants is inaccurate. We wished to determine how well cerebellar vermis dimensions might predict gestational age in infants of birth weight less than 2000 g. We obtained suitable midline(More)
