Aim: To assess the CT scan aspect of cement bridges used to repair incudostapedial joint discontinuity (ISD) and correlate these observations to audiometric data over time.

Material And Methods: A retrospective study in 12 patients with cement rebridging for ISD compared pre- and post-operative pure-tone average thresholds, Hounsfield units (HU), and bridge size and position on postoperative CT scans.

Results: Mean pre- and post-operative air-bone gap (ABG) was 24.

In France, the passive surveillance of lyssaviruses in bats started in 1989, with the first positive case found in the East of the country. In 2000, the French bat rabies surveillance network in France was improved on the basis of the one used for the surveillance of fox rabies. The objectives of this network are to improve bat rabies surveillance by increasing the number of specimens and to provide an estimation of rabies incidence in bat populations across the country.

European bat lyssavirus type 1a (EBLV-1a) was first identified in central France from a serotine bat (Eptesicus serotinus) collected at the end of 2002. Rabies was diagnosed by reference rabies diagnosis methods and molecular tools. Phylogenetic analysis of 14 viral isolates obtained from French bats infected with EBLV-1 between 1989 and the end of 2002 against 47 nucleoprotein sequences showed a north-west to east distribution of EBLV-1a virus and a south to north distribution of EBLV-1b virus, isolates of which could be divided into two groups: group 1 in north-eastern France and group 2 in central and north-western France.

A simplified hemi-nested reverse transcriptase polymerase chain reaction (hnRT-PCR) has been developed to determine specifically the European Bat Lyssavirus 1 (EBLV-1) nucleoprotein gene. The specificity of this method was determined by using the seven genotypes of lyssavirus by RT-PCR, Southern blot and sequence analysis. Compared to the rabies diagnostic methods, the hnRT-PCR showed a higher sensitivity for the detection of small amounts of EBLV-1 virus.

Unlabelled: Dihydropyrimidine dehydrogenase (DPD) is the rate limiting enzyme of 5-fluoro-uracil (5-FU) catabolism. DPD rhythmicity, peak at 1:00 is an important determinant of 5-FU tolerability and has practical implications for the pattern of chronomodulated delivery of the drug. Maximal tolerated doses have been highed and anti-tumour activity also.

During a serosurvey of domestic dogs in Tanzania, a rapid fluorescent focus inhibition test (RFFIT) and a liquid-phase blocking ELISA (LPBE) were used to measure rabies antibodies in vaccinated and unvaccinated dogs. Post-vaccination titres measured by LPBE correlated closely with those found by RFFIT. Of 567 unvaccinated dogs tested using the LPBE, 42 (7.

Two rabies virus strains collected from naturally infected foxes in France in 1976 and 1986 were inoculated in 2 groups each consisting of 10 foxes (approximately 50 lethal doses50 mouse intracerebral per fox). Another 20 healthy foxes were kept in the same cages as the inoculated animals in order to study the transmission of both strains. All the inoculated foxes became rabid and transmitted rabies to their cage companion.

Mouse inoculation test (MIT) is a highly sensitive test for rabies diagnosis but slow and expensive. To detect rabies virus an in vitro technique using Neuro 2a cell culture (CC) was compared with MIT in two laboratories. In one laboratory, CC appeared to be on the whole more sensitive than MIT, nevertheless MIT was the only one to detect some positive samples.

A model in mice was developed in order to check if a resistance against rabies could be naturally and genetically selected in a line of mammals. A more resistant strain of mice (DBA/2) was identified. However, up to present, all attempts have failed in view to create a resistant strain of swiss mice in breeding individuals surviving to rabies infection.

A 75 years old man had a chronic lymphoid leukemia for 5 years. Within a period of three months he developed a polyneuritis. The biopsy of a peripheral nerve showed a large cellular infiltration by lymphocytes.
