Telemedicine in veterinary practice

Veterinary surgeons have a long tradition of consulting one another about problem cases and many have unwittingly practised telemedicine when discussing cases by telephone or by sending laboratory reports by telefax. Specific veterinary telemedicine applications have been in use since the early 1980s, but little research has been undertaken in this field. The Pubmed and CAB International databases were searched for the following Boolean logic-linked keywords; veterinary and telemedicine, veterinary and telecare, animal and telemedicine, animal and telecare and veterinary and e-mail and an additional search was made of the worldwide web, using Google Scholar. This returned 25 papers which were reviewed. Of these only 2 report research. Sixteen papers had no references and 1 author was associated with 13 papers. Several themes emerge in the papers reviewed. These include remarks about the use of telemedicine, the benefits that can and are derived from the use of telemedicine, areas of practice in which telemedicine is being used, ethical and legal issues around the practice of telemedicine, image standards required for telemedicine, the equipment that is required for the practice of telemedicine, advice on ways in which digital images can be obtained and educational aspects of telemedicine. These are discussed. Veterinary practice has lagged behind its human counterpart in producing research on the validity and efficacy of telemedicine. This is an important field which requires further research.     

Ferrets in veterinary practice

Ferrets (Mustela putorius furo) show up with increasing frequency in veterinary practice. Originally domesticated for hunting of rodents and rabbits, they became very popular pets which require legal permission though and the further fulfillment of various husbandry needs. Ferrets have to be maintained on a high protein diet which in practice is often done with commercial feline products. Physical examination is similar to dogs and cats whereas the frequent occurrence of non-specific symptoms require further diagnostic investigation including blood sampling, radiology, ultrasound or exploratory laparatomy. The preferred anaesthetic method is the direct face mask induction and maintenance using isoflurane without pr?medication. Special attention of veterinarians has to be paid to canine distemper vaccination, the specialized reproduction physiology of the females (jills) which can develop, if unmated, a persistent oestrus with fatal consequences of hyperestrogenism, as well as the frequent occurrence of further endocrine disorders, congestive cardiomyopathy and gastrointestinal diseases.     

Diagnostic ultrasound in veterinary practice: How safe is it?

This paper provides information on the safety of ultrasonic diagnostic procedures as currently used in veterinary practice. The known mechanisms of action are described and selected literature on biological effects of ultrasound is reviewed. Current international consensus is presented on the safety of medical ultrasound with respect to thermal effects. To date, there is no independently verified clinical evidence that the level of exposure delivered to the tissues during scanned grey-scale (‘B-mode’) imaging has any adverse effects. Lung haemorrhage has been observed in animal experiments using diagnostic exposures, but the effects have not been reported in the foetus. Equipment that uses pulsed Doppler transmits higher acoustic outputs in a stationary beam, and can produce temperature increases that may have significant biological consequences. When considering sonographic and pulsed Doppler examinations of the prenatal animal, the safety margins are small and the operator should be aware of the acoustic output of the equipment, the exposure time, and the sensitivity of target tissues.
