Computed tomographic appearances of massive neonatal hemangioma of the liver: a case report.

The unusual computed tomographic appearances of a hepatic hemangioma in a neonate are reported. The liver was replaced by cystlike spaces that enhanced with contrast. These blood-filled spaces were responsible for the cardiac failure that improved following ligation of the hepatic artery.

A prospective study of deep vein thrombosis of the leg in children on halo-femoral traction.

This prospective study was performed to determine the true incidence of deep vein thrombosis of the lower limb in children who had undergone halo-femoral traction to correct scoliosis before operation. Bilateral ascending phlebography of the lower limbs was performed on 54 children two days before spinal fusion and Harrington rod instrumentation. Two patients developed clinical evidence of thrombosis whilst on traction. This diagnosis was confirmed by phlebography. The other 52 children had no clinical evidence of thrombosis and their venograms were normal. The incidence of thrombosis was 3.7 per cent and clinically silent thrombosis did not occur.

Double contrast preparations: an in vitro study of some antifoaming agents.

An apparatus is described for the study of foam formation in double contrast preparations in vitro. Antifoaming agents are shown to be of considerable benefit to the double contrast technique, silicone and silicone-free antifoamers being equally effective. Silicone antifoamers are preferred because of their wide clinical acceptability. Antifoamer formulation and concentration are found to be critical factors in determining efficacy of foam suppression, and may lead to erroneous results in the clinic.
