This study was undertaken to determine the accuracy of color Doppler imaging in the diagnosis of portal vein thrombosis. Two hundred fifteen patients were studied with color Doppler imaging to determine patency of the main portal vein. Sonographic findings were confirmed in 75 patients, aged 19 to 66 years. Correlation with angiography was obtained in 13(More)
We report on two families in which one or two children had a severe disorder of skeletal development detected by prenatal ultrasonography. The children died postnatally and showed typical radiological and biochemical findings of perinatal hypophosphatasia. Biochemical analysis revealed a low activity of alkaline phosphatase (AP) and a high value of(More)
PURPOSE The aim of this study was to make a comparison of predictive values of neurodevelopmental assessment and evaluation of videotaped spontaneous movements of premature infants for motor outcome. METHODS We performed a prospective longitudinal study of 103 VLBW infants, 96 (455-1490 g, 24-35 weeks gestational age) including (a) a neurodevelopmental(More)
Thin sections of dermatofibromas, of a basal cell epithelioma, a patch stage lesion of Kaposi's sarcoma, a case of angiolymphoid hyperplasia with eosinophilia, and one case of malignant mastocytosis were incubated with antibody to factor XIIIa (FXIIIa). Regardless whether the tissue had been embedded in Lowicryl K4M, Epon, or Araldite, labeling was found in(More)
A prospective study was undertaken to characterize the rate of increase, time of peak values and rates of decrease in serum concentrations of C-reactive protein (CRP) in a group of infants treated for neonatal bacterial infection. A total of 176 consecutively admitted neonates with birth weight >1500 g and without mechanical ventilation or central lines in(More)
To determine the advantages of atrioventricular (AV) sequential pacing over ventricular demand pacing, paired cardiovascular hemodynamic studies were performed in each pacing mode at a constant heart rate. The paired studies included determination of ejection fraction (EF) by echocardiography and gated blood pool radionuclide scanning, and of cardiac output(More)
This study determines if prolonged aortic crossclamp time (ACC) with the use of cold potassium cardioplegia during elective cardiac valve replacement contributed to the risk of operative mortality in 225 patients. In Group I (143 patients), the ACC was less than 120 minutes (mean 86) and in Group II (82 patients), it was greater than 120 minutes (mean 146).(More)
Investigations were performed to study the epileptiform activity, induced by a local injection of penicillin (PCN) into the posterior thalamus (pTh) of the awake rat, and to compare it with the epilepsy induced in the same animals 2 weeks later by an injection of PCN into the motor cortex (MC). Using EEG recordings, 1) the distribution of focal cortical(More)
