Abstract

Objective—To evaluate the accuracy of ultrasound-guided
fine-needle aspiration of the liver and cytologic
findings in dogs and cats.

Design—Retrospective study.

Animals—56 dogs and 41 cats.

Procedure—Medical records of dogs and cats evaluated
from 1990 to 2000 by use of cytologic and histopathologic
examination of the liver were reviewed. Histologic
and cytologic diagnoses were categorized as vacuolar
hepatopathy, inflammation, neoplasia, cirrhosis, primary
cholestasis, shunt, normal, and other.

Results—Overall agreement between the histopathologic
diagnosis and cytologic diagnosis was found in 17
of the 56 (30.3%) canine cases and 21 of the 41 (51.2%)
feline cases. Vacuolar hepatopathy was the category
with the highest percentage of agreement. Vacuolar
hepatopathy was identified via cytologic examination in
7 of 11 and 15 of 18 dogs and cats, respectively, in
which histopathologic examination revealed that it was
the predominant disease process. However, it was also
the category that was most commonly misdiagnosed
via cytologic examination. Inflammatory disease was
accurately identified cytologically in 5 of 20 and 3 of 11
dogs and cats, respectively.

Conclusions and Clinical Relevance—Acknowledging
the limitations of cytology and the extent of discrepancies
between cytologic and histopathologic findings in
dogs and cats will help clinicians make better decisions
in diagnosing liver disease. (J Am Vet Med Assoc 2004;

Authors: Edinboro Charlotte H. , Scott-Moncrieff J. Catharine , Janovitz Evan , Thacker H. Leon , Glickman Larry T. 
Published: December 2005

AbstractObjective—To determine whether the increasing prevalence of feline hyperthyroidism is the result of aging of the cat population and whether consumption of canned foods at various times throughout life is associated with increased risk of hyperthyroidism.Design—Retrospective and case-control studies.Study Population—Medical records of 169,576 cats, including 3,570 cats with hyperthyroidism, evaluated at 9 veterinary school hospitals during a 20-year period, and 109 cats with hyperthyroidism (cases) and 173 cats without hyperthyroidism (controls).Procedure—Age-adjusted hospital prevalence of hyperthyroidism was calculated by use of Veterinary Medical Database records. On the basis of owners' questionnaire responses, logistic regression was used to evaluate associations between consumption of canned food and development of hyperthyroidism.Results—Age-specific hospital prevalence of feline hyperthyroidism increased significantly from 1978 to 1997. Overall, consumption of pop-top canned (vs dry) food at various times throughout life and each additional year of age were associated with greater risk of developing hyperthyroidism. In female cats, increased risk was associated with consumption of food packaged in pop-top cans or in combinations of pop-top and non-pop-top cans. In male cats, increased risk was associated with consumption of food packaged in pop-top cans and age.Conclusions and Clinical Relevance—These findings suggest that the increasing prevalence of feline hyperthyroidism is not solely the result of aging of the cat population and that canned foods may play a role.

Thyroid function and pregnancy status in broodmares
Authors: Meredith Travis B. , Dobrinski Ina 
Published: December 2005

AbstractObjective—To determine whether thyroid function was associated with pregnancy status in broodmares. Design—Prospective study.Design–Prospective study.Animals—79 Thoroughbred and Standardbred broodmares between 2 and 22 years old.Procedure—Serum triiodothyronine (T3) concentration was measured before and 2 hours after IV administration of thyrotropin releasing hormone (TRH), and serum thyroxine (T4) concentration was measured before and 4 hours after TRH administration. Pregnancy status was monitored by means of transrectal ultrasonography beginning 16 days after ovulation.Results—Baseline T3and T4concentrations varied widely. In all mares, serum T3concentration increased in response to TRH administration. Serum T4concentration increased in response to TRH administration in all but 2 mares. Pregnancy rate was 76%. Baseline and stimulated serum T3and T4concentrations were not significantly different between mares that became pregnant and those that did not.Conclusions and Clinical Relevance—Results suggest that decreased thyroid function is uncommon in mares and poor thyroid function is not a common cause of infertility. Thus, the practice of indiscriminately treating broodmares with thyroid hormone to enhance fertility appears questionable at this time. (J Am Vet Med Assoc2004;224:892–894)
Environmental surveillance for Salmonella enterica in a veterinary teaching hospital
Authors: Burgess Brandy A. , Morley Paul S. , Hyatt Doreene R. 
Published: December 2005

AbstractObjective—To evaluate the extent of environmental contamination withSalmonella entericain a veterinary teaching hospital.Design—Longitudinal study.Samples—Environmental samples obtained from 69 representative locations within a veterinary teaching hospital by use of a commercially available electrostatic wipe.Procedure—Environmental samples were obtained for bacteriologic culture, and antimicrobial susceptibility testing was performed on each environmental isolate. Environmental isolates were compared with isolates obtained from animals during the same period to investigate potential sources of environmental contamination.Results—54S entericaisolates were recovered from 452 (11.9%) cultured environmental samples .Five different serotypes were recovered; the most common serotypes wereSNewport andSAgona. Within the 5 serotypes recovered, 10 distinguishable phenotypes were identified by use of serotype and antimicrobial susceptibility patterns. Of the environmental isolates, 41 of 54 (75.9%) could be matched to phenotypes of isolates obtained from animal submissions in the month prior to collection of environmental samples.Conclusions and Clinical Relevance—Results indicated that environments in veterinary hospitals can be frequently contaminated withS entericanear where infected animals are managed and fecal specimens containingS entericaare processed for culture in a diagnostic laboratory. Bacteriologic culture of environmental samples collected with electrostatic wipes is an effective means of detecting contamination in a veterinary hospital environment and may be beneficial as part of surveillance activities for other veterinary and animal-rearing facilities.

AbstractObjective—To compare seroprevalences of antibodies againstBartonella henselaeandToxoplasma gondiiand fecal shedding ofCryptosporidiumspp,Giardiaspp, andToxocara catiin feral and pet domestic cats.Design—Prospective cross-sectional serologic and coprologic survey.Animals—100 feral cats and 76 pet domestic cats from Randolph County, NC.Procedure—Blood and fecal samples were collected and tested.Results—Percentages of feral cats seropositive for antibodies againstB henselaeandT gondii(93% and 63%, respectively) were significantly higher than percentages of pet cats (75% and 34%). Percentages of feral and pet cats withCryptosporidiumspp (7% of feral cats; 6% of pet cats),Giardiaspp (6% of feral cats; 5% of pet cats), andT catiova (21% of feral cats; 18% of pet cats) in their feces were not significantly different between populations. Results of CBCs and serum biochemical analyses were not significantly different between feral and pet cats, except that feral cats had a significantly lower median PCV and significantly higher median neutrophil count.Conclusions and Clinical Relevance—Results suggested that feral and pet cats had similar baseline health status, as reflected by results of hematologic and serum biochemical testing and similar prevalences of infection withCryptosporidiumspp,Giardiaspp, andT cati. Feral cats did have higher seroprevalences of antibodies againstB henselaeandT gondiithan did pet cats, but this likely was related to greater exposure to vectors of these organisms.

Published: December 2005

AbstractObjective—To evaluate antiplatelet effects and pharmacodynamics of clopidogrel in cats.Design—Original study.Animals—5 purpose-bred domestic cats.Procedure—Clopidogrel was administered at dosages of 75 mg, PO, every 24 hours for 10 days; 37.5 mg, PO, every 24 hours for 10 days; and 18.75 mg, PO, every 24 hours for 7 days. In all cats, treatments were administered in this order, with at least 2 weeks between treatments. Platelet aggregation in response to ADP and collagen and oral mucosal bleeding times (OMBTs) were measured before and 3, 7, and 10 days (75 and 37.5 mg) or 7 days (18.75 mg) after initiation of drug administration. Serotonin concentration in plasma following stimulation of platelets with ADP or collagen was measured before and on the last day of drug administration. Platelet aggregation, OMBT, and serotonin concentration were evaluated at various times after drug administration was discontinued to determine when drug effects were lost.Results—For all 3 dosages, platelet aggregation in response to ADP, platelet aggregation in response to collagen, and serotonin concentration were significantly reduced and OMBT was significantly increased at all measurement times during drug administration periods. All values returned to baseline values by 7 days after drug administration was discontinued. No significant differences were identified between doses. None of the cats developed adverse effects associated with drug administration.Conclusions and Clinical Relevance—Results suggest that administration of clopidogrel at dosages ranging from 18.75 to 75 mg, PO, every 24 hours, results in significant antiplatelet effects in cats.

Authors: Croft Lara A. , Graham John P. , Schaf Susan A. , Jacobson Elliott R. 
Published: December 2005

Abstract

Objective—To describe the gross cross-sectional
anatomy of green turtles (Chelonia mydas) and evaluate
magnetic resonance imaging (MRI) for detection
of internal tumors in green turtles with cutaneous
fibropapillomatosis.

Design—Prospective study.

Animals—3 dead green turtles, 1 healthy green turtle,
and 8 green turtles with cutaneous fibropapillomatosis.

Procedures—Gross cross-sectional anatomy of a
dead turtle was described. Each live turtle underwent
a complete physical examination, and dorsoventral
whole-body survey radiographic views were obtained.
Magnetic resonance imaging was performed in dorsal
and transverse planes. Radiographs and magnetic
resonance images were examined for evidence of
internal nodules. Results were compared with
necropsy findings in 5 of 8 turtles.

Results—Nodules in the lungs of 2 turtles were
detected via radiography, whereas pulmonary nodules
were detected in 5 turtles via MRI. No other visceral
nodules were detected via radiography; however,
masses in the stomach and adjacent to the bladder
and kidneys were detected in 1 turtle via MRI. Other
extrapulmonary abnormalities observed at necropsy
were not detected on MR images.

Conclusions and Clinical Relevance—MRI may be
valuable for detection of internal tumors in green turtles
with cutaneous fibropapillomatosis. Nodules
were more apparent in the lungs than in other organs.
Results of MRI may serve as prognostic indicators for
sea turtles undergoing assessment, treatment, and
rehabilitation. Clinical application may be limited by
cost and availability of MRI technology. (J Am Vet Med Assoc 2004;225:1428–1435)

Published: December 2005

AbstractObjective—To identify specific components of veterinarian- client-patient communication during clinical appointments in companion animal practice.Design—Cross-sectional descriptive study.Sample Population—A random sample of 50 companion animal practitioners in southern Ontario and a convenience sample of 300 clients and their pets.Procedure—For each practitioner, 6 clinical appointments (3 wellness appointments and 3 appointments related to a health problem) were videotaped, and the Roter interaction analysis system (RIAS) was used to analyze the resulting 300 videotapes. Statements made during each appointment were classified by means of a communication framework reflecting the 4 essential tasks of the appointment (ie, data gathering, education and counseling, relationship building, and activation and partnership).Results—57% of the veterinarians contacted (50/87) and 99% of the clients contacted agreed to participate in the study. Mean duration of the appointments was 13 minutes. Typically, veterinarians contributed 62% of the total conversation and clients contributed 38%. Fifty-four percent of the veterinarian interaction was with the client, and 8% was with the pet. Data gathering constituted 9% of the veterinarian-to-client communication and was primarily accomplished through closed-ended questioning; 48% of veterinarian-to-client communication involved client education and counseling, 30% involved relationship building, and 7% involved activation and partnership (the remaining 6% constituted orientation).Conclusions and Clinical Relevance—Results suggest that the RIAS was a reliable method of assessing the structure, process, and content of veterinarianclient-patient communication and that some veterinarians do not use all the tools needed for effective communication.

Published: December 2005

AbstractObjective—To determine the relationship between the caudolateral curvilinear osteophyte (CCO) and osteoarthritis associated with hip dysplasia in dogs.Design—Longitudinal cohort study.Animals—48 Labrador Retrievers from 7 litters.Procedure—In each of 24 sex- and size-matched pairs fed the same diet, a restricted-fed dog was fed 25% less than a control dog for life. The dogs' hips were evaluated in the standard ventrodorsal hip-extended radiographic projection at 16, 30, and 52 weeks of age and then yearly for life. Histologic examination of hip joint tissues was performed on 45 dogs.Results—Median age at death was 11.2 years. Adjusting for feeding group, dogs with a CCO were 3.7 times as likely to develop radiographic signs of osteoarthritis than those without a CCO. Stratified by diet, 100% of the control dogs with a CCO developed radiographic signs of osteoarthritis and 55% of restricted-fed dogs with a CCO developed radiographic signs of osteoarthritis. The CCO was the first radiographic change seen in 22 of 29 (76%) dogs with osteoarthritis. Overall, 35 of 37 (95%) dogs with a CCO had histopathologic lesions of osteoarthritis.Conclusions and Clinical Relevance—Results indicate a relationship between a CCO on the femoral neck and subsequent development of radiographic signs of osteoarthritis in Labrador Retrievers evaluated over their life span. A CCO is an important early radiographic indication of osteoarthritis associated with canine hip dysplasia. (J Am Vet Med Assoc2004;225:233–237)
Evaluation of complications and prognostic factors associated with administration of total parenteral nutrition in cats: 75 cases (1994–2001)
Authors: Pyle Sally C. , Marks Stanley L. , Kass Philip H. 
Published: December 2005

AbstractObjective—To determine frequency and types of complications, prognostic factors, and primary diseases affecting clinical outcome associated with administration of total parenteral nutrition (TPN) in cats.Design—Retrospective study.Animals—75 cats that received TPN for ≥ 12 hours.Procedure—Medical records were reviewed, and information was obtained on signalment, history, problems at initial evaluation, physical examination findings, weight and changes in weight while receiving TPN, duration in the hospital before initiation of TPN, the type of TPN catheter used, duration of TPN administration, and final diagnosis. Laboratory results obtained immediately prior to TPN and at 24 and 96 hours following initiation of TPN administration were compared.Results—Reports of weight loss at initial evaluation, hyperglycemia at 24 hours, or diagnosis of chronic renal failure were significantly associated with increased mortality rate. Greater serum albumin concentrations prior to and at 96 hours following TPN administration were significantly associated with decreased mortality rate. Mechanical and septic complications were infrequent and not associated with increased mortality rate. Most cats had multiple diseases. The overall mortality rate was 52%; among 75 cats, 36 recovered, 23 were euthanatized, and 16 died as a result of their primary illness or complications associated with their illness.Conclusions and Clinical Relevance—Results indicated high mortality rate in cats maintained on TPN that had multiple concurrent diseases associated with a poor prognosis. Indicators of poor prognosis included a history of weight loss, hyperglycemia at 24 hours following TPN administration, hypoalbuminemia, and chronic renal failure.

Published: December 2005

Abstract

Objective—To evaluate owner compliance with longterm
home monitoring of blood glucose concentrations
in diabetic cats and assess the influence of
home monitoring on the frequency of reevaluation of
those cats at a veterinary hospital.

Design—Retrospective study.

Animals—26 cats with diabetes mellitus.

Procedure—Medical records of diabetic cats for
which home monitoring was undertaken were
reviewed, and owners were contacted by telephone.
Signalment, laboratory test results, insulin treatment
regimen, details of home monitoring, clinical signs
during treatment, frequency of follow-up examinations,
and survival times were evaluated.

Results—Monitoring of cats commenced within 12
weeks (median, 3 weeks) after initial evaluation; 8
owners were unable to perform home monitoring,
and 1 cat was euthanatized after 1 week. In 17 cats,
duration of home monitoring was 4.8 to 46.0 months
(median, 22.0 months); 6 cats died after 7.0 to 18.0
months (median, 13.0 months). In 11 cats, home
monitoring was ongoing at completion of the study
(12.0 to 46.0 months' duration). Fourteen owners
completed blood glucose curves every 2 to 4 weeks.
Cats managed with home monitoring received higher
dosages of insulin, compared with cats that were not
monitored. Four of 17 cats managed by home monitoring
had transient resolution of diabetes mellitus for
as long as 1 year. Home monitoring did not affect the
frequency of reevaluation at the veterinary hospital.

Conclusions and Clinical Relevance—Owner compliance
with long-term home monitoring appeared to
be satisfactory, and home monitoring did not affect
the frequency of reevaluation of patients by veterinarians.

Tension band stabilization of fractures and luxations of the thoracolumbar vertebrae in dogs and cats: 38 cases (1993–2002)
Authors: Voss Katja , Montavon Pierre M. 
Published: December 2005

AbstractObjective—To determine the outcome of dogs and cats in which a tension band technique was used to stabilize traumatic fractures and luxations of the thoracolumbar vertebrae.Design—Retrospective study.Animals—38 client-owned animals (22 dogs and 16 cats) weighing between 1.4 and 45 kg (3 and 99 lb).Procedure—Medical records of cats and dogs that underwent tension band stabilization of thoracolumbar fractures and luxations at the University of Zurich between 1993 and 2002 were reviewed. The stabilization technique was a modification of a spinal stapling technique with a figure 8 hemicerclage wire placed in a tension band fashion across the lesion. Neurologic status, lesion location and type, and concomitant traumatic injuries were assessed from the medical records and preoperative radiographs. Clinical outcome and complications were determined through follow-up examinations or telephone conversations with the owners.Results—Complete or satisfactory neurologic recovery was achieved in 30 (79%) patients. Seven patients were euthanatized (6 owing to poor neurologic recovery and 1 owing to implant failure), and 1 dog was managed at home despite paraplegia. Clinically, only 4 patients (11%) had evidence of implant or fixation failure; all were dogs weighing > 16 kg (35 lb).Conclusions and Clinical Relevance—Results suggest that the tension band technique may be appropriate for stabilization of fractures and luxations of the thoracolumbar vertebrae in cats and small- or medium- sized dogs. In larger dogs, fixation strength may be insufficient to stabilize certain fracture types and ancillary external or internal fixation methods may be needed. (J Am Vet Med Assoc2004;225:78–83)

AbstractObjective—To estimate seroprevalence ofMycobacterium aviumsubspparatuberculosis(MAP) infection among adult dairy cows in Colorado and determine herd-level factors associated with the risk that individual cows would be seropositive.Design—Cross-sectional observational study.Animals—10,280 adult (≥ 2 years old) dairy cows in 15 herds in Colorado.Procedure—Serum samples were tested with a commercial ELISA. A herd was considered to be infected with MAP if results of mycobacterial culture of ≥ 1 individual cow fecal sample were positive or if ≥ 1 culled cow had histologic evidence of MAP infection.Results—424 of the 10,280 (4.12%) cows were seropositive. Within-herd prevalence of seropositive cows ranged from 0% to 7.82% (mean, 2.6%). Infection was confirmed in 11 dairies. Cows in herds that had imported ≥ 8% of their current herd size annually during the preceding 5 years were 3.28 times as likely to be seropositive as were cows in herds that imported < 8%. Cows in herds with ≥ 600 lactating cows were 3.12 times as likely to be seropositive as were cows in herds with < 600 lactating cows. Cows in herds with a history of clinical signs of MAP infection were 2.27 times as likely to be seropositive as were cows in herds without clinical signs.Conclusions and Clinical Relevance—Annual importation rate, herd size, and whether cows in the herd had clinical signs typical of MAP infection were associated with the risk that individual cows would be seropositive for MAP infection.
