The culmination of the first European Veterinary Week was a meeting in Hannover, Germany, on November 14, 2008, exploring international trends and perspectives in food animal practice. The meeting coincided with ‘Eurotier’, the world’s largest exhibition covering professional animal husbandry and management. Issues discussed included bluetongue, the EU’s Community Animal Health Strategy and zoonoses.

The effect of left‐sided valvular regurgitation (LSVR) on the mortality of middle‐aged and older horses was investigated in a prospective cohort study involving 19 yards and 1153 horses. The horses were examined to determine whether they had a cardiac murmur and its type, and their age, sex, breed type and occupation were recorded. They were followed up at intervals of two years by postal questionnaire, and after four years information on 773 horses was available. There was no significant difference in the mortality of the horses with and without LSVR, but small horses had a significantly higher risk of having LSVR than small ponies (odds ratio [OR] 2·33), and older horses were slightly more likely to have LSVR than young horses (OR 1·07). Twenty‐nine per cent of the deaths reported by the owners were due to orthopaedic problems, 23·3 per cent to gastrointestinal problems, and only 7·9 per cent to cardiovascular problems. Orthopaedic problems were the main cause of death in the horses, and gastrointestinal problems were the main cause of death in the ponies.

The reticular motility in 144 cattle with vagal indigestion was evaluated by ultrasonography; 97 had proximal functional stenosis (reticulo‐omasal stenosis) and 47 had distal functional stenosis (pyloric stenosis). A 3·5 MHz linear transducer was used to measure the frequency, amplitude, duration and speed of the reticular contractions per three minutes while the animals were standing and unsedated. The mean (sd) number of contractions per three minutes was 4·3 (2·09) with a range from 0 to 12; nine of the cattle had one or two contractions, 17 had three contractions, 59 had four or five contractions, 37 had more than five contractions and 12 had reticular atony. The cattle with proximal functional stenosis had 4·6 (2·01) contractions per three minutes, significantly more (P<0·05) than those with distal functional stenosis (3·6 [2·16]). The position, contour and size of the reticulum, the amplitude and speed of the contractions and the area surrounding the reticulum did not differ significantly between the two groups.

Four green iguanas scheduled for euthanasia were used to compare the extent of collateral tissue damage associated with CO2 laser and 4·0 MHz radiosurgery. The iguanas were anaesthetised and a series of three skin and three muscle incisions was made by 4·0 MHz radiosurgery (0·18 mm wire electrode, 25 W, cut mode) and CO2 laser (0·3 mm ceramic tip, 15 W focused beam super‐pulse mode), and three incisions were made with a scalpel blade as controls. Following euthanasia, a total of 60 skin and 36 muscle sections were evaluated histologically. Radiosurgery and the laser both produced bloodless incisions, but radiosurgery caused significantly less collateral tissue damage in the skin (307 [97] v 386 [108] µm) and the muscle (18 [7] v 91 [15] µm).
