The aim of this study was to validate a novel inexpensive training device as a means of improving the psychomotor skills involved in the manipulation of a fibreoptic endoscope. Seventy-five subjects attempted to pass a fibreoptic endoscope through the device five times, with each attempt timed to the nearest second. Although prior clinical experience of fibreoptic intubation was associated with better performance, all groups showed improvement with each attempt. Qualitative feedback indicated that the device required subjects to use similar skills to those used in clinical practice. This study supports the use of such a device in training and assessment although further studies will be required to determine whether the skills learned on the device can be transferred to the clinical environment.

Summary A group of racehorses in training was examined on several occasions with a fibreoptic endoscope and monitored for viral infection. Only equine herpes virus-2 (EHV-2) infection was detected. Pharyngeal lymphoid hyperplasia (PLH) was present in all horses and decreased in severity with age. There was no association between PLH severity and antibody titres to EHV-1, or with the isolation of EHV-2. Finishing position in races was not affected by PLH severity. Exercise induced pulmonary haemorrhage (EIPH) was evident on 23 out of 49 (47 per cent) examinations after maximal speed training exercise. Eighteen out of 19 (95 per cent) horses examined on at least two occasions had EIPH but its occurrence was not predictable. Observable mucoid or mucopurulent exudate was present in the trachea in 60 out of 118 (50 per cent) examinations and the amount seen was increased following exercise.
