History

A 13-year-old castrated male domestic shorthair cat was evaluated by a referring veterinarian because of progressive hair loss, anorexia, diarrhea, and profound weakness that developed over a period of a few weeks. The cat was referred to the Veterinary Medical Teaching Hospital at the University of Missouri for further assessment.

Clinical and Gross Findings

On initial evaluation, the cat's mentation was obtunded and mild dehydration was evident. Severe alopecia was present on the ventral aspects of the abdomen and neck, axillae, medial aspects of the forelimbs and hind limbs, periocular region, and nasal planum ( Figure 1 ). The

Abstract

Objective—To evaluate a continuous glucose monitoring system (CGMS) for use in dogs, cats, and horses.

Design—Prospective clinical study.

Animals—7 horses, 3 cats, and 4 dogs that were clinically normal and 1 horse, 2 cats, and 3 dogs with diabetes mellitus.

Procedure—Interstitial glucose concentrations were monitored and recorded every 5 minutes by use of a CGMS. Interstitial glucose concentrations were compared with whole blood glucose concentrations as determined by a point-of-care glucose meter. Interstitial glucose concentrations were also monitored in 2 clinically normal horses after oral and IV administration of glucose.

Results—There was a positive correlation between interstitial and whole blood glucose concentrations for clinically normal dogs, cats, and horses and those with diabetes mellitus. Events such as feeding, glucose or insulin administration, restraint, and transport to the clinic were recorded by the owner or clinician and could be identified on the graph and associated with time of occurrence.

Conclusions and Clinical Relevance—Our data indicate that use of CGMS is valid for dogs, cats, and horses. This system alleviated the need for multiple blood samples and the stress associated with obtaining those samples. Because hospitalization was not required, information obtained from the CGMS provided a more accurate assessment of the animal's glucose concentrations for an extended period, compared with measurement of blood glucose concentrations. Use of the CGMS will promote the diagnostic and research potential of serial glucose monitoring. (J Am Vet Med Assoc 2003;223: 987–992)

Abstract

Objective—To compare measurements of body temperature obtained with auricular thermometers versus rectal thermometers in dogs with otitis externa.

Design—Prospective study.

Animals—100 client-owned dogs: 50 with and 50 without clinical evidence of otitis externa.

Procedure—Dogs were evaluated for the presence of otitis externa on the basis of clinical signs, otoscopic examination, and cytologic evaluation of ear exudate. Auricular and rectal temperatures were obtained simultaneously in all dogs prior to and following ear examination.

Results—There was a high correlation between auricular and rectal temperatures in dogs with otitis externa both prior to and after ear manipulation. Significant differences were not detected in temperature measurements among dogs with different degrees of otitis externa.

Conclusions and Clinical Relevance—Auricular temperature readings obtained by use of an auricular thermometer in dogs with otitis externa are accurate measurements of body temperature, compared with rectal temperature measurements. Temperature measurements are reliable before and after examination of the ear canal. (J Am Vet Med Assoc 2002; 221:378–380)
