essential for the congenital type of cholesteatoma particularly in the petrous pyramid. Magnetic resonance has largely replaced CT for the soft tissue demonstration of masses in the petrous temporal bone and posterior cranial fossa particularly when assisted by Gadolinium enhancement. GdMRI is now the definitive investigation for acoustic neuromas although adequate preliminary screening is nece...

out ascending bifemoral reconstruction in order to bypass the peritoneal cavity as described by R. J. Baird. In both cases, the femoral arteries were exposed first, to ascertain the adequacy of the run off. This being satisfactory, the ascending aorta was exposed through a median sternotomy. An 8 mm preformed axillo-bifemoral knitted Dacron Graft was pre-clotted and having applied a side occlud...

Groundwater is the main source of water for domestic use in Nigeria because it is perceived to be clean. The presence of geogenic contaminants (arsenic and fluoride), and the level of awareness of their presence in groundwater in Ibadan, Nigeria was examined in this study. A total of one hundred and twenty groundwater samples were collected from hand dug wells which tap into shallow aquifers an...

Cobalt and copper concentrations were measured in 599 lamb livers collected at slaughter from 58 sheep flocks in 6 different parts of Norway in 1993. Information about pasture, additional feeding and mineral supplements in the flocks was obtained through a questionnaire. Average hepatic levels of cobalt in the lamb flocks varied from < 0.003 to 0.22 microg/g ww, and of copper from 5 to 240 micr...

Carcinoma of the kidney accounts for 1-2% of all malignances. Surgery remains the only 'curative therapy available with the prognosis worsening with advancing stage. Renal cell carcinoma is unique in producing tumour thrombi which grow a'?ng the renal vein, inferior vena cava and may ultimately invade the right atrium. Although such venous involvement places the tumour in a higher stage (stage ...

A case of gastro-duodenal Crohn's disease was preSented, in whom there was also intestinal and colonic lnvolvement. He subsequently underwent a partial gastrectomy with Roux-en-Y anastomosis, dissecting the lrst 18ins of jejunum, which was macroscopically involved with Crohn's disease and post-operatively fared very well. As this was an unusual case and gastrou?denal Crohn's disease is relative...

not being strictly scientific papers abstracts have not been obtained. Nevertheless they were of considerable interest and the following has been compiled from notes taken at the time. Mr. Roger Mitchell opened the proceedings with a talk about 'Jersey's Past and Present History'. The Channel Isles are the only part of the Dukedom of Normandy remaining to the heirs of William the Conqueror. Jer...

A non-contact approach for the alignment of optical elements and systems is described which allows the operator to clearly distinguish tilt and decentration errors of the individual optical elements. Advantages over alternate methods are discussed, and several examples of the use of the alignment tool are presented with experimental results.
