The authors describe the rare case of a deep lying invasive growing lipoma before and also behind the neck vertebra in two separate localities in one patient. Only briefly they mention the contribution of the preoperative CT at infiltrative fat tumours with still have a recidive risk when they are not totally removed. The authors point up the difficulties in the histopathological diagnostic in the different lipomas.
In the first part of this article we review what has been learnt from the analysis of the sequence of HCMV. A summary of this information is presented in the form of an updated map of the viral genome. HCMV is representative of a major lineage of herpesviruses distinct from previously sequenced members of this viral family and demonstrates striking differences in genetic content and organization. The virus encodes approximately 200 genes, including nine gene families, a large number of glycoprotein genes, and homologues of the human HLA class I and G protein-coupled receptor genes. The HCMV sequence thus provides a sound basis for future molecular studies of this highly complex eukaryotic virus. The second part discusses the practical rate of DNA sequencing as deduced from this and other studies. The 229 kilobase pair DNA genome of human cytomegalovirus (HCMV) strain AD169 is the largest contiguous sequence determined to date, and as such provides a realistic benchmark for assessing the practical rate of DNA sequencing as opposed to theoretical calculations which are usually much greater. The sequence was determined manually and we assess the impact of new developments in DNA sequencing.

A recently discovered alloy of cobalt and samarium (CO5Sm) has exceptional magnetic properties. A laboratory evaluation was made of the grip force of samples of this alloy of a size suitable for dental use. A review of both dental and general literature points to the need for establishing, prior to widespread usage, that magnetic fields are harmless to surrounding tissues.
A simple technique has been outlined for the removal of fractured root fragments. It can be applied to a number of situations and employs instruments which are readily available in the dental surgery.
