To compare thoracic radiographs of clinically normal dogs and dogs with mild clinical heartworm disease with images transmitted by a desktop, two-way audiovisual teleconferencing system.


Prospective, matched-set study.

Study Population

50 thoracic radiographs from clinically normal and heartworm-infected dogs and the digitally transmitted images of those radiographs.


Thoracic radiographs from 25 clinically normal dogs and 25 dogs infected with 1 to 24 heartworms were evaluated by 3 clinicians. Using classic criteria for heartworm disease, evaluations of radiographs and images transmitted digitally over 2 highspeed data-transfer telephone lines (56 kilobits/s/line) were performed. Clinicians were asked to determine whether dogs had radiographic signs of heartworm disease.


Clinicians’ ability to detect heartworm disease did not differ between interpretations of radiographs and those of transmitted images.

Clinical Implications

Radiographic images transmitted via a teleconference system can be used to provide reliable diagnostic information. Thoracic radiographs can be interpreted at a remote site permitting rapid consultation and immediate advice on clinical management. (J Am Vet Med Assoc 1997;211:1245–1248)

Objective—To compare owner-assessed ease of administration and overall acceptability of 3 chemically inactive formulations administered PO to cats.

Animals—90 healthy client-owned cats.

Procedures—Cats were randomly assigned to receive 1 of 3 formulations PO once daily for 14 days: medium chain triglyceride (MCT) oil, dissolving thin film strips (proprietary ingredients), or gelatin capsules filled with microcrystalline cellulose. Owners administered the formulations and rated ease of administration daily on a 10-cm visual analogue scale (VAS). At the end of the study, owners rated overall acceptability of formulations from their own perspective and their overall perception of acceptability to their cat.

Results—Mean VAS scores for daily ease of administration of MCT oil and film strips were significantly higher than scores for gelatin capsules at all time points, except on days 2, 4, and 7. There was no difference between MCT oil and film strip formulation scores. Mean VAS scores were 8.8 (MCT oil), 8.9 (film strips), and 7.4 (gelatin capsules) for overall acceptability to owners and 8.0 (MCT oil), 8.3 (film strips), and 6.7 (gelatin capsules) for overall owner-perceived acceptability to cats.

Conclusions and Clinical Relevance—Daily ease of administration on 11 of 14 days and overall owner-perceived acceptability to cats were scored significantly higher for film strips and MCT oil, compared with scores for gelatin capsules. Overall acceptability to owners followed a similar pattern; however, the differences were not significant. Dissolving thin film strip or MCT oil vehicles may allow for easier PO administration of medication to cats than does administration of gelatin capsules.
