25. Echocardiographic screening in neonates undergoing surgery for selected gastrointestinal malformations.
To compare echocardiography with clinical examination, radiography, and electrocardiography for the detection of congenital heart defects (CHD) a four year prospective study was carried out in 166 neonates with selected congenital gastrointestinal malformations (anorectal anomaly, tracheo-oesophageal fistula, duodenal atresia, exomphalos, and gastroschisis).

26. Sensitive Detection of HBsAg Mutants by a Gap Ligase Chain Reaction Assay
Hepatitis B virus (HBV) surface gene variants have been associated with diagnostic escape and immune escape following vaccination. The most common mutation observed in these variants is a glycine-to-arginine substitution at amino acid 145 (G145R). In order to sensitively detect the presence of this mutant in serum, a new molecular detection system was develo

27. Significance of detection of extra metacentric microchromosome in amniotic cell culture.
A metacentric bisatellited microchromosome was detected in all metaphases from an amniotic culture performed because of maternal age. A wide-ranging survey of the literature failed to disclose any consistent anomaly associated with such a marker, but did reveal that the clinical picture of patients manifesting it could range from complete normality through m

28. Simultaneous mapping of the tricuspid and mitral valve annuli at electrophysiological study.
BACKGROUND--Mapping of the right free wall in patients with accessory pathways is difficult compared with that of the left free wall where the coronary sinus permits stable and accurate location of the electrodes used for endocardial mapping. Furthermore, the sequential roving catheter method is less satisfactory than multiple simultaneous electrode recordin
