    Pancreatic carcinoma in a neonate (1983)

    Pediatric radiology 13 (1983), S. 284-286

    Notizen: Abstract The clinical and radiographic findings in a neonate with adenocarcinoma of the head of the pancreas are presented. CT revealed the mass to be well defined, with an inhomogeneous density before and after intravenous contrast enhancement. Ultrasound revealed the mass to be mainly densely echogenic with small, irregular, echo-free areas. The portal vein was intimately applied to the posterior aspect of the mass. The literature concerning adenocarcinoma of the pancreas in the pediatric age group is reviewed.

    Biliary disease in metachromatic leukodystrophy (1983)

    Notizen: Abstract This paper illustrates the previously unreported sonographic changes in the biliary tract in metachromatic leukodystrophy (MLD). Gallbladder wall thickening due to sulfatide deposition, intraluminal globules of sulfatide or papillomatosis may cause symptoms referrable to the biliary tract in these patients. A series of patients whom, we have studied is briefly alluded to in order to bring to the attention of the radiologist MLD as a rare cause of biliary disease in children.

    Hypoxic/ischaemic cerebral injury in the neonatal brain (1983)
    Springer
    Pediatric radiology 13 (1983), S. 307-312 
    Details
    ISSN: 1432-1998
    Schlagwort(e): Ultrasound ; Neonate ; Hypoxic/ischaemic lesion
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Abstract Ultrasound has been used in 11 neonates whose history or clinical features suggested the possibility of hypoxic/ischaemic lesions. The ultrasound findings were correlated with computed tomographic findings in nine infants and with pathological findings in two. On ultrasound scan, areas of increased echoes represented both hypoxic/ischaemic and haemorrhagic lesions. However, the distinction between them could not be made with certainty. Cystic changes were shown clearly by ultrasound as were cerebral vascular pulsations in and adjacent to the areas of increased echoes. With computed tomography, hypoxic/ischaemic lesions were represented by areas of decreased density and haemorrhagic lesions by areas of increased density. Computed tomography failed to clearly demonstrate the cystic changes. Three types of lesions, viz. diffuse, focal and periventricular were based on the location of brain injury, the former two occurring in term infants and the latter in premature infants. Ultrasound has been shown to be of value for definition of the site and extent of hypoxic/ischaemic cerebral lesions in the newborn and for observation of their evolution.

    Congenital epithelial splenic cysts in children (1982)
    Springer
    Pediatric radiology 12 (1982), S. 119-125 
    Details
    ISSN: 1432-1998

    Thema: Medizin
    Notizen: Abstract The clinical, radiographic and sonographic features of four children with congenital epithelial splenic cysts are described. All four cases presented with a left upper quadrant mass and few symptoms. In one case the spleen descended into the pelvis in the upright position. In three cases the sonographic findings showed the mass to be completely sonolucent. In the fourth case the mass was echogenic and echoes were distributed homogeneously throughout the mass. These internal echoes were due to the presence of fat droplets within the cyst fluid. Internal echoes may also be due to hemorrhage into the cyst. In all four cases a rim of splenic tissue was visible around part of the cyst.

    Notizen: 1H-NMR Spectroscopic Assignments of Isomeres to Cyclization Reactions of Benzo-condensed N-HeterocyclesCyclic N-acyl benzazoles show downfield shifts of the aromatic Ha proton at the 1H-n.m.r. spectrum from 0.5 to 1.95 ppm which allows an assignment of possible isomeres and in some cases statements about the tautomerism. The ΔδHa values of 40 different azolo-, azino-, and azepino condensed benzimidazoles are given.

    Notizen: Cyanic Acid Esters. 29. Benzoxazoline-thione-N-imid Esters and Their Consecutive ReactionsOxazoline-thiones-(2) and aryl cyanates react to form the corresponding isoureas 4. These compounds are remarkably stable against electrophilic reagents. The aminolysis of 4 proceeds two pathways: a transformation of the imid ester residue to the amin and a ring opening reaction by attack of the amin to the C=S-bond. The hydrazinolysis causes a ring-transformation of the oxazoline- to the 1,3,4-triazole system.
