Evaluation of stability over time for measures of heart-rate variability in overtly healthy Doberman Pinschers
Authors: Calvert Clay A. , Wall Michelle 
Published: December 2005

AbstractObjective—To determine whether results of analysis of heart-rate variability (HRV) in overtly healthy Doberman Pinschers remain stable over time.Animals—24 overtly healthy client-owned Doberman Pinschers.Procedure—The HRV was analyzed in time- and frequency- domains from 24-hour ambulatory electrocardiographic (Holter) monitor recordings. Activity during paired tests (tests 1 and 2) was similar (17 dogs) or nearly identical (7). Holter recordings and HRV analyses of those 17 dogs were repeated at a mean ± SD of 65 ± 50 weeks (median, 51 weeks; range, 10 to 177 weeks), whereas it was repeated for the other 7 dogs at 3 to 9 weeks (mean, 7.3 ± 2.1 weeks).Results—Differences between test 1 and test 2 were not significantly different, except for 24-hour means of the normal beat-to-normal beat (NN) intervals in all 5-minute segments. Strongest correlations were for SD of all NN intervals and root mean square successive difference between adjacent NN intervals of the time-domain analyses and total power, verylow frequency power, and high-frequency power of the frequency-domain analyses. When activity during tests 1 and 2 in 7 dogs was stringently controlled, the differences were not significantly different, and correlation factors for the 24-hour HRV analyses exceeded 0.83.Conclusion and Clinical Relevance—Variables from sequential HRV analyses in overtly healthy Doberman Pinschers with normal echocardiograms are moderately stable when physical activity is not stringently controlled and extremely stable for at least 3 to 9 weeks when physical activity is stringently controlled.

Abstract

Objective—To determine the effects of florfenicol
injection on the meat characteristics of the cervical
muscles in cattle.

Animals—100 steers (mean weight, 380 kg).

Procedure—In 50 calves, florfenicol (25 ml, twice)
was injected into the cervical muscles of 1 side of the
neck, and saline (0.9% NaCl) solution (25 ml, twice)
was injected into the cervical muscles of the other
side of the neck. In the remaining 50 calves, florfenicol
was injected into the cervical muscles of 1 side of
the neck, and nothing was injected into the cervical
muscles of the other side of the neck. Animals were
slaughtered 132 days later, and samples of the cervical
muscles were submitted for histologic evaluation
and measurement of shear forces.

Results—2 injection sites used in the present study
had extensive lesions, and both of these were sites
where florfenicol had been injected. However, histologic
scores for the florfenicol injection sites were not
significantly different from scores for the contralateral
saline solution injection sites and uninjected control
sites. In addition, shear force values were not significantly
different between sites in which florfenicol had
been injected and the contralateral sites.

Conclusion and Clinical Relevance—Results suggest
that few reactions should be expected with
injection of florfenicol into the cervical muscles in
steers and that reactions that do occur will consist
mainly of fibrosis and infiltration of adipose tissue.
However, shear force values, a measure of tenderness
of the meat, should not be affected. (Am J Vet

Association of pneumonia in foals caused by Rhodococcus equi with farm soil geochemistry
Authors: Martens Ronald J. , Cohen Noah D. , Chaffin M. Keith , Waskom Jeffery S. 
Published: December 2005

AbstractObjective—To quantify and compare geochemical factors in surface soils from horse-breeding farms with horses with pneumonia caused byRhodococcus equi(affected farms) and horse-breeding farms with no history of pneumonia caused byR equi(unaffected farms).Sample Population—Soil from 24R equi-affected farms and 21 unaffected farms.Procedure—Equine veterinary practitioners throughout Texas submitted surface soil samples from areas most frequented by foals, onR equiaffected and unaffected horse-breeding farms in their practice. Soil samples were assayed for the following factors: pH, salinity, nitrate, phosphorus, potassium, calcium, magnesium, sodium, sulfur, zinc, iron, manganese, and copper. Median values for all factors were recorded, and differences between affected and unaffected farms were compared.Results—Significant differences in soil factors were not detected between affected and unaffected farms; hence, there was no association between those factors andR equidisease status of the farms.Conclusion and Clinical Relevance—The surface soil factors monitored in this study were not significant risk factors for pneumonia caused byR equi. As such, it is not possible to determine whether foals on a given farm are at increased risk of developing disease caused byR equion the basis of these factors. Data do not support altering surface soil for factors examined, such as alkalinization by applying lime, as viable control strategies forR equi. (Am J Vet Res2002;63:95–98)

Published: December 2005

AbstractObjective—To evaluate effects of dietary insoluble fiber on control of glycemia in cats with naturally acquired diabetes mellitus.Design—Randomized controlled crossover trial.Animals—16 cats with naturally acquired diabetes mellitus.Procedure—Cats were fed a diet high in insoluble fiber (HF) containing 12% cellulose (dry-matter basis) or a diet low in insoluble fiber (LF) for 24 weeks; they were fed the other diet for the subsequent 24 weeks. Caloric intake and insulin treatment were adjusted to maintain stable body weight and control of glycemia, respectively. Cats were allowed an adaption period of 6 weeks after initiation of a diet, after which control of glycemia was evaluated at 6-week intervals for 18 weeks. Variables assessed included serum glucose concentration measured during the preprandial state, blood glycated hemoglobin concentration, serum glucose concentration measured at 2-hour intervals for 12 hours beginning at the time of the morning insulin injection, 12-hour mean serum glucose concentration, and mean fluctuation in serum glucose concentration from the 12-hour mean serum glucose concentration.Results—Mean daily caloric intake, body weight, or daily insulin dosage did not differ significantly between cats when fed HF and LF diets. Mean preprandial serum glucose concentration, most postprandial serum glucose concentrations, and the 12-hour mean serum glucose concentration were significantly lower when cats consumed the HF diet, compared with values when cats consumed the LF diet.Conclusions and Clinical Relevance—These results support feeding a commercially available diet containing approximately 12% insoluble fiber (dry-matter basis) to cats with naturally acquired diabetes mellitus.

Laryngeal paralysis in cats: 16 cases (1990–1999)
Authors: Schachter Sara , Norris Carol R. 
Published: December 2005

AbstractObjective—To determine clinical signs, physical examination findings, radiographic features, and concurrent diseases in cats with laryngeal paralysis, as well as evaluate the outcome of medical or surgical management.Design—Retrospective study.Animals—16 cats.Procedure—Medical records from January 1990 to April 1999 were examined for cats with laryngeal paralysis. Signalment, clinical signs, physical examination findings, cervical and thoracic radiographic findings, laryngeal examination results, and clinical outcome were reviewed.Results—No breed or sex predilection was identified in 16 cats with laryngeal paralysis. The most common clinical signs included tachypnea or dyspnea, dysphagia, weight loss, change in vocalization, coughing, and lethargy. Clinical signs were evident for a median of 245 days. Airway obstruction was apparent on cervical and thoracic radiographic views in 9 cats. Examination of the larynx revealed bilateral laryngeal paralysis in 12 cats and unilateral laryngeal paralysis in 4 cats. The 4 cats with unilateral disease were managed with medical treatment, and 3 of these had acceptable long-term outcomes. Seven of 12 cats with bilateral paralysis underwent surgery; procedures performed included left arytenoid tie back, bilateral arytenoid tie back and ventriculocordectomy, and partial left arytenoidectomy. One cat was euthanatized as a result of complications from surgery.Conclusions and Clinical Relevance—Laryngeal paralysis is an uncommon cause of airway obstruction in cats. Cats with less severe clinical signs (often with unilateral paralysis) may be successfully managed with medical treatment, whereas cats with severe airway obstruction (often with bilateral paralysis) may benefit from surgical intervention.(J Am Vet Med Assoc2000;216:1100–1103)
Sexual harassment in the veterinary academic environment
Authors: MacAllister Carolynn T. , Guglick MaryAnn , Dale Joanna 
Published: December 2005

AbstractObjective—To survey faculty and house officers of clinical departments of colleges of veterinary medicine (CVM) to identify characteristics of sexual harassment (SH) in the veterinary academic environment, to report the opinions of survey respondents on how SH is being handled, and to determine how the process can be improved at veterinary academic institutions.Procedure—On the basis of lists obtained from 25 CVM, a survey was mailed to 1,294 academic veterinarians. Four hundred seventy-eight completed surveys were returned.Results—The prevalence of SH in the population of respondents was 31%. Nonphysical forms of SH were reported 6 times as often as physical forms of harassment, with the most common type reported being offensive sexual comments and unwanted attention. Fear of reprisal was the most prevalent reason cited by respondents for not confronting the harasser. Survey respondents rated the following as very important to improve the system of dealing with SH at their academic institution: guarantee of protection from retaliation, assurance of confidentiality, clear explanation of what will happen to you, and a clearer definition of SH.Conclusion—A clear definition of SH is the first step in preventing SH. Other cited steps include professional development programs to educate the academic population as to what constitutes SH, inform the entire academic population what the institution's SH policy is, and enforce this policy with sensitivity, fairness, confidentiality, and quick resolve to protect the victim.

Evaluation of a commercial enzyme-linked immunosorbent assay for detection of Borrelia burgdorferi exposure in dogs
Authors: Sheets James T. , Rossi Cynthia A. , Kearney Brian J. , Moore George E. 
Published: December 2005

AbstractObjective—To evaluate the effectiveness of a commercially available ELISA kit for detecting antibodies againstBorrelia burgdorferiindogs.Sample Population—Banked sera from 440 military working dogs were used for serologic analyses.Procedure—Serum samples were analyzed for antibodies againstB burgdorferiby use of a commercially available ELISA and subsequently by western blot analysis as a confirmatory test.Results—Results from the ELISA indicated that 89 (20%) samples were positive for exposure toB burgdorferior canine Lyme disease vaccine, and 351 (80%) were negative. Follow-up testing by western blot analysis indicated that results for 109 (25%) samples were positive and 331 (75%) were negative for exposure. All samples that had positive results on the ELISA also had positive results on western blot analysis (true positives). Of the 351 samples that had negative results on the ELISA, only 331 had negative results on western blot analysis (true negatives). The remaining 20 samples had positive results on western blot analysis. By use of a standard 2 X 2 table, it was determined that the ELISA had a sensitivity of 82%, specificity of 100%, positive predictive value of 100%, and negative predictive value of 94%.Conclusion and Clinical Relevance—The commercial ELISA kit evaluated in this study appeared to lack adequate sensitivity for detecting all potential cases of borreliosis in dogs. The ELISA was also unable to discriminate natural exposure from exposure attributable to vaccination, which could complicate interpretation of positive results and treatment of dogs with clinical signs.

Comparison of absorptive capacities of original and modified Schirmer tear test strips in dogs
Authors: van der Woerdt Alexandra , Adamcak Alexandra 
Published: December 2005

Abstract

Objective—To compare in vitro and in vivo absorptive
capacities of modified Schirmer tear test strips with
those of original strips, and to establish reference values
for use with the modified strips.

Design—Prospective study.

Animals—100 dogs.

Procedure—In vitro absorptive capacity was determined
by immersing strips in an irrigating solution for
15 seconds and recording amount of wetting. In vivo
absorptive capacity was determined by placing an original
Schirmer tear test strip in 1 eye and a modified
strip in the other eye of 50 dogs with normal or abnormal
tear production. Time required to wet 10 mm of
each strip was recorded. Measurements were repeated
30 minutes later after reversing which strip was
placed in the left or right eye. Reference values (mean
± SD) were determined by recording the time required
to wet 10 mm of the modified strip in 50 healthy dogs.

Results—Amount of wetting was significantly less
and time required to wet 10 mm was significantly
greater for the modified strip, compared with the original
strip. Reference values determined for the modified
strip were 32 ± 11 seconds in the right eye, 33 ±
11 seconds in the left eye, and 32 ± 10 seconds in
both eyes.

Conclusion and Clinical Relevance—Absorptive
capacities of the original and modified Schirmer tear
test strips were significantly different. Reference values
determined for 1 strip should not be used for the
other strip. (J Am Vet Assoc 2000;216:1576–1577)
Analysis of cerebrospinal fluid from dogs and cats after 24 and 48 hours of storage
Authors: Bienzle Dorothee , McDonnell John J. , Stanton James B. 
Published: December 2005

Abstract

Objective—To compare differential cell counts and
cell characteristics of CSF samples analyzed immediately
or after storage for 24 and 48 hours at 4 C with
and without the addition of autologous serum.

Design—Prospective study.

Animals—36 dogs and 6 cats.

Procedure—CSF samples were collected from the
cerebellomedullary cistern and divided into 250-μl
aliquots. Slides of CSF samples were prepared by use
of cytocentrifugation immediately and after 24 and 48
hours of storage with addition of autologous serum
(final concentrations, 11 and 29%). Differential cell
counts and number of unrecognizable cells were
compared among preparations.

Results—Significant differences in the differential
cell counts were not detected among samples analyzed
before or after storage. Although the number of
unrecognizable cells increased with storage time,
this did not result in a significant effect on cell distribution
or diagnosis. Cells in CSF samples stored with
11% serum more closely resembled cells in fresh
samples than did cells in samples stored with 29%
serum.

Conclusions and Clinical Relevance—CSF samples
collected at veterinary clinics remote from a diagnostic
laboratory or during nonoperational hours may be
preserved through the addition of autologous serum.
Evaluation of such samples is likely to result in an
accurate diagnosis for at least 48 hours after collection.

Association between postoperative outcome and results of magnetic resonance imaging and computed tomography in working dogs with degenerative lumbosacral stenosis
Authors: Jones Jeryl C. , Banfield Catherine M. , Ward Daniel L. 
Published: December 2005

AbstractObjective—To determine whether results of magnetic resonance imaging (MRI) and computed tomography (CT) are associated with postoperative outcome in working dogs with degenerative lumbosacral stenosis.Design—Prospective cohort study.Animals—12 dogs treated surgically for degenerative lumbosacral stenosis.Procedure—Procedure—The lumbosacral vertebral column was examined before surgery by use of MRI and CT and after surgery by use of CT. Outcome, based on performance in standardized training exercises, was assessed 6 months after decompressive surgery. Associations between imaging results and postoperative outcome were determined by use of a Fisher exact test and logistic regression.Results—None of the dogs were able to perform their duties before surgery. By 6 months after surgery, 8 of 12 dogs had been returned to full active duty. Nerve tissue compression was effectively localized by use of CT and MRI. Significant associations between results of imaging studies and postoperative outcome were not identified.Conclusions and Clinical Relevance—Surgical intervention is justified in high-performance working dogs with degenerative lumbosacral stenosis. However, results of imaging studies may be less important than clinical or surgical factors for predicting outcome in affected dogs. (J Am Vet Med Assoc2000;216:1769–1774)

Published: December 2005

AbstractObjective—To examine postoperative ocular hypertension (POH) and other variables as predictors of the risk of developing glaucoma after cataract surgery in dogs.Design—Retrospective study.Animals—220 dogs that had cataract surgery.Procedure—Medical records of 220 dogs (346 eyes) that had extracapsular cataract removal or phacoemulsification of cataracts were reviewed. With respect to glaucoma development, 8 variables were analyzed, which included development of POH, breed, sex, age at time of surgery, eye (right vs left), phacoemulsification time, intraocular lens (IOL) placement (yes or no), and stage of cataract development. Eyes developed glaucoma within 6 or 12 months of surgery or did not have signs of glaucoma at least 6 or 12 months after cataract surgery.Results—Of 346 eyes, 58 (16.8%) developed glaucoma after surgery. At 6 months, 32 of 206 (15.5%) eyes examined had glaucoma; at 12 months, 44 of 153 (28.8%) eyes examined had glaucoma. Median follow-up time was 5.8 months (range, 0.1 to 48 months). Mixed-breed dogs were at a significantly lower risk for glaucoma, compared with other breeds. Eyes with IOL placement were at a significantly lower risk for glaucoma, compared with eyes without IOL placement. Eyes with hypermature cataracts were at a significantly higher risk for glaucoma, compared with eyes with mature or immature cataracts.Conclusions and Clinical Relevance—Multiple factors appear to contribute to the onset of glaucoma in dogs after cataract surgery. Complications prohibiting IOL placement during cataract surgery may lead to a high risk of glaucoma development. (J Am Vet Med Assoc2000;216:1780–1786)
Clinical, bacteriologic, serologic, and pathologic features of infections with atypical Taylorella equigenitalis in mares
Authors: Katz Jonathan B. , Evans Lawrence E. , Hutto David L. , Schroeder-Tucker Linda C. , Carew Ann M. , Donahue J. Michael , Hirsh Dwight C. 
Published: December 2005

Abstract

Objective—To characterize clinical, serologic, bacteriologic,
cytologic, and pathologic endometrial responses
of mares to 2 donkey-origin atypical bacterial isolates
resembling Taylorella equigenitalis.

Design—Prospective in vivo study.

Animals—10 healthy mares.

Procedure—Mares in estrus (2/group) were inoculated
by intrauterine infusion with 2 isolates of classic T
equigenitalis or 2 isolates of atypical Taylorella sp or
were sham-inoculated. Bacteriologic, serologic, clinical,
uterine, cytologic, and pathologic endometrial
responses were assessed 4, 11, 21, 35, and 63 days
after inoculation and on day 111 in mares with positive
culture results on day 63.

Results—One atypical isolate failed to cause infection.
The second atypical isolate and both classic T
equigenitalis isolates induced similar transient metritis
and cervicitis. Both classic isolates and 1 atypical
isolate induced anti-T equigenitalis complement-fixing
antibodies detectable at day 11. Classic isolates and
an atypical isolate provoked intense neutrophilic
endometritis followed by a resolving, subacute, neutrophilic-mononuclear endometrial response. The
atypical isolate and classic isolates were recovered
from the uterus, clitoral fossa, or clitoral sinus of one
or both exposed mares for as long as 111 days.

Conclusions and Clinical Relevance—Atypical
Taylorella sp infections should be considered as a differential
diagnosis of equine infertility in US-origin
mares, even those not exposed to stallions from
countries where contagious equine metritis occurs.
The origins and prevalence of atypical Taylorella sp
infection in US horses and donkeys are undetermined.

Pneumothorax in horses: 40 cases (1980–1997)
Authors: Boy Mary G. , Sweeney Corinne R. 
Published: December 2005

AbstractObjective—To characterize pneumothorax in horses and to describe clinical signs, diagnostic testing, and clinical outcome of horses with pneumothorax.Design—Retrospective study.Animals—40 horses.Procedure—Medical records of horses with pneumothorax were reviewed to obtain information on signalment, history, clinical signs, diagnostic testing, treatment, and clinical outcome.Results—Horses developed pneumothorax secondary to pleuropneumonia (17 horses), open wounds of the thorax (9), closed trauma to the thorax (7), surgery on the upper portion of the respiratory tract (3), and surgery involving the thoracic cavity (1); 3 horses had pneumothorax of unknown cause. Clinical signs included tachypnea, dyspnea, cyanosis, lack of lung sounds on auscultation of the dorsal aspect of the thorax, fever, tachycardia, signs of depression or anxiousness, and cough. Radiography and ultrasonography were useful to definitively diagnose pneumothorax. Pneumothorax was bilateral in 47.5% (19/40) and unilateral in 42.5% (17/40) of horses; designation of unilateral versus bilateral was not recorded in the remaining 4 horses. Horses with pneumothorax secondary to pleuropneumonia more commonly had unilateral pneumothorax (64.7% for unilateral vs 29.4% for bilateral; not specified for 1 horse). Horses with pneumothorax secondary to pleuropneumonia were less likely to survive than horses with pneumothorax secondary to other causes (35.3 vs 69.6% survived, respectively).Conclusions and Clinical Relevance—Pleuropneumonia is an important cause of pneumothorax in horses. Classic clinical signs of pneumothorax may not be evident. Radiography, ultrasonography, or both may be required for diagnosis. Prognosis for survival is better for horses with pneumothorax not associated with pleuropneumonia. (J Am Vet Med Assoc2000;216:1955–1959)
