Scintigraphic abnormalities of the pelvic region in horses examined because of lameness or poor performance: 128 cases (1993–2000)
Authors: Davenport-Goodall Celia L. M. , Ross Michael W. 
Published: December 2005

Abstract

Objective—To identify scintigraphic abnormalities in
the pelvic region of horses examined because of hind
limb lameness or poor performance and determine
the clinical relevance of areas of abnormal radiopharmaceutical
uptake (ARU) in these horses.

Design—Retrospective study.

Animals—128 horses.

Procedure—Medical records were reviewed, and
information on signalment, history, admitting complaints,
physical examination findings, and results of
lameness examinations was recorded. Clinical relevance
of areas of ARU was determined by comparison
with results of other diagnostic tests. For horses
with clinically relevant areas of ARU, follow-up information
was obtained through telephone interviews
with owners and trainers and analysis of race records.

Results—Areas of ARU were identified in the tuber
coxae (25 horses), ischiatic tuber (9), hip joint (10),
third trochanter (10), ilium (5), sacral tuber region (22),
greater trochanter (1), cranial femoral cortex (1), skeletal
muscle surrounding the pelvis (34), or multiple
areas (11). In 44 horses, areas of ARU were associated
with the primary cause of lameness; in 51, areas
of ARU were not associated with the primary cause
of lameness; and in 33, the primary cause of lameness
was not determined. Thirty-six of the 44 horses
with clinically relevant areas of ARU were available for
follow-up; 15 (42%) had a good outcome.

Conclusions and Clinical Relevance—Results suggest
that pelvic scintigraphy may be useful in identifying
abnormalities in horses with hind limb lameness
or poor performance. (J Am Vet Med Assoc 2004;224:

AbstractObjective—To determine the biological behavior of liposarcomas in dogs and identify clinical signs, the effect of treatment on survival time, and potential prognostic factors.Design—Retrospective study.Animals—56 dogs with histologically confirmed liposarcoma.Procedure—Information was obtained on signalment, tumor size, location of the tumor, stage of disease, remission duration, overall survival time, cause of death, type of surgery (incisional biopsy, marginal excision, or wide excision), and any additional treatments given.Results—Surgery consisted of incisional biopsy in 6 dogs, marginal excision in 34, and wide excision in 16. Twenty-five dogs had histologic evidence of tumor cells at the surgical margins and 28 did not (status of the margins was unknown in 3 dogs). Twelve of 43 dogs had local recurrence. Median survival time was 694 days, and the only factor significantly associated with survival time was type of surgery performed. Median survival times were 1,188, 649, and 183 days, respectively, for dogs that underwent wide excision, marginal excision, and incisional biopsy. Factors that were not found to be significantly associated with survival time included tumor size, status of the margins, tumor location, and histologic subtype.Conclusions and Clinical Relevance—Results suggest that in dogs, liposarcomas are locally invasive neoplasms that rarely metastasize and occur primarily in appendicular or axial locations and that wide excision is preferred to marginal excision when feasible.

AbstractObjective—To determine reproductive capacity of naturally breeding free-roaming domestic cats and kitten survival rate.Design—Prospective cohort and retrospective crosssectional study.Animals—2,332 female cats brought to a trap-neuterreturn clinic for neutering and 71 female cats and 171 kittens comprising 50 litters from a cohort study of feral cats in managed colonies.Procedure—Data collected for all cats included pregnancy, lactation, and estrus status and number of fetuses for pregnant cats. Additional data collected for feral cats in managed colonies included numbers of litters per year and kittens per litter, date of birth, kitten survival rate, and causes of death.Results—Pregnant cats were observed in all months of the year, but the percentage of cats found to be pregnant was highest in March, April, and May. Cats produced a mean of 1.4 litters/y, with a median of 3 kittens/litter (range, 1 to 6). Overall, 127 of 169 (75%) kittens died or disappeared before 6 months of age. Trauma was the most common cause of death.Conclusions and Clinical Relevance—Results illustrate the high reproductive capacity of free-roaming domestic cats. Realistic estimates of the reproductive capacity of female cats may be useful in assessing the effectiveness of population control strategies. (J Am Vet Med Assoc2004;225:1399–1402)

Published: December 2005

AbstractObjective—To determine the time and financial costs of programs for live trapping feral cats and determine whether allowing cats to become acclimated to the traps improved trapping effectiveness.Design—Prospective cohort study.Animals—107 feral cats in 9 colonies.Procedure—15 traps were set at each colony for 5 consecutive nights, and 5 traps were then set per night until trapping was complete. In 4 colonies, traps were immediately baited and set; in the remaining 5 colonies, traps were left open and cats were fed in the traps for 3 days prior to the initiation of trapping. Costs for bait and labor were calculated, and trapping effort and efficiency were assessed.Results—Mean ± SD overall trapping effort (ie, number of trap-nights until at least 90% of the cats in the colony had been captured or until no more than 1 cat remained untrapped) was 8.9 ± 3.9 trap-nights per cat captured. Mean overall trapping efficiency (ie, percentage of cats captured per colony) was 98.0 ± 4.0%. There were no significant differences in trapping effort or efficiency between colonies that were provided an acclimation period and colonies that were not. Overall trapping costs were significantly higher for colonies provided an acclimation period.Conclusions and Clinical Relevance—Results suggest that these live-trapping protocols were effective. Feeding cats their regular diets in the traps for 3 days prior to the initiation of trapping did not have a significant effect on trapping effort or efficiency in the present study but was associated with significant increases in trapping costs.

Published: December 2005

Abstract

Objectives—To describe preoperative, surgical, and
postoperative findings and determine prognostic indicators
and treatment recommendations in dogs treated
surgically for gallbladder mucocele.

Design—Retrospective study.

Animals—22 client-owned dogs.

Procedures—Medical records of dogs with gallbladder
mucoceles that were treated surgically
were reviewed. History, clinical signs, results of
selected clinicopathologic analyses and abdominal
ultrasonography, surgical procedure performed,
results of histologic examination of a liver biopsy
specimen, and survival time were recorded. Followup
information was obtained via telephone interview
with owners and referring veterinarians.

Results—Dogs were 7 to 15 years of age and had nonspecific
clinical signs (vomiting, anorexia, and lethargy).
Physical examination findings included icterus, signs of
depression, and signs of discomfort on palpation of the
abdomen . Sixteen dogs had a definitive diagnosis and
6 dogs were strongly suspected of having a gallbladder
mucocele on the basis of results of abdominal ultrasonography.
Fifteen dogs survived after surgery; 3 of
these dogs had bile-induced peritonitis, and 4 had pancreatitis.
One dog was euthanatized as a result of
severe pancreatitis, and 1 was euthanatized because of
acute renal failure; 5 dogs died as a result of pancreatitis,
cholecystitis, or bile-induced peritonitis. Hepatic
abnormalities were detected histologically in all dogs.

Conclusions and Clinical Relevance—No predictors
of survival were identified. No associations
between outcome of surgical treatment (survival vs
nonsurvival) and preoperative findings, biliary rupture,
surgical procedure performed, results of histologic
examination of the liver, or development of pancreatitis
were found. Cholecystoduodenostomy and
cholecystectomy appear to be acceptable treatments
for gallbladder mucocele. (J Am Vet Med Assoc 2004;225:1418–1422)

AbstractObjective—To determine whether beef herds could increase profitability by reducing production cost per 100 lb (hundredweight [CWT]; ie, 45.4 kg) of calf through implementation of advice from teams of veterinarians and county extension agents supported by university specialists.Design—Longitudinal study.Sample Population—6 commercial cow-calf herds comprising 1,927 cows.Procedure—Teams of veterinarians and county extension agents provided advice on 25 profitable ranch management practices to herd owners for 3 years. Use of each practice in herds was measured on a scale of 1 to 5 for baseline year 1999. Similar measurements were made at the end of each year for comparison with baseline values. Outcomes were measured by standardized performance analysis.Results—Mean weaning weight of calves per exposed cow of the 6 herds increased significantly from 1999 (2000, 26.8 kg [59 lb; 17%]; 2001, 49.1 kg [108 lb; 31%]; and 2002, 43.2 kg [95 lb; 27%]). Mean cost per CWT of calf decreased significantly from the 1999 value (2000, −$20.04 [−18%]; 2001, −$33.40 [−29%]; and 2002, −$22.52 [−20%]). Additional profits for the 6 herds were $54,407 in 2000, $135,695 in 2001, and $116,089 in 2002 (3-year total of $306,191). Mean increase in management score of herds was positively correlated with increase in net income and accounted for > 60% of increased profits.Conclusions and Clinical Relevance—Profitability of beef cow-calf operations can be substantially increased through a team approach by identifying opportunities for improvements in management and helping ranch managers implement profitable practices.

AbstractObjective—To determine the outcome of and prognostic indicators for dogs and cats with pneumoperitoneum and no history of penetrating trauma.Design—Retrospective study.Animals—43 dogs and 11 cats.Procedure—Medical records of dogs and cats with radiographic evidence of pneumoperitoneum and no history of penetrating trauma were reviewed. Information collected included signalment, previous medical problems, initial complaint, duration of illness, physical examination findings, radiographic findings, laboratory abnormalities, abdominocentesis results, bacterial culture results, concurrent diseases, hospitalization time, and outcome. Abdominal radiographs were reviewed, and radiographic severity of pneumoperitoneum was classified. For those animals that underwent exploratory laparotomy, time from admission to surgery and results of histologic examination of biopsy specimens were recorded.Results—24 (44%) animals survived and were discharged from the hospital, but none of the variables examined was associated with whether animals survived. Rupture of the gastrointestinal tract was the cause of pneumoperitoneum in 40 animals. However, cause and location of gastrointestinal tract rupture was not associated with whether animals survived. Twenty-three of 40 (58%) animals that underwent exploratory laparotomy survived, compared with only 1 of 14 animals that did not undergo surgery.Conclusions and Clinical Relevance—Results suggest that pneumoperitoneum in dogs and cats without any history of penetrating trauma is most commonly associated with rupture of the gastrointestinal tract and requires immediate surgical intervention. Even when appropriate treatment is instituted, the shortterm prognosis is only fair. (J Am Vet Med Assoc2004;225:251–255)

AbstractObjective—To determine signalment, clinical signs, diagnostic findings, treatment, and outcome for cats with atrial fibrillation (AF).Design—Retrospective study.Animals—50 cats.Procedure—Medical records of cats that met criteria for a diagnosis of AF (ECG consisting of at least 2 leads, clear absence of P waves, supraventricular rhythm, and convincingly irregularly irregular rhythm) and had undergone echocardiography were reviewed.Results—There were 41 males (37 castrated) and 9 females (7 spayed). Forty-one were of mixed breeding; 9 were purebred. Mean ± SD age was 10.2 ± 3.7 years. The most common chief complaints were dyspnea, aortic thromboembolism, and lethargy. In 11 cats, AF was an incidental finding. Mean ± SD ventricular rate was 223 ± 36 beats/min. The most common echocardiographic abnormalities were restrictive or unclassified cardiomyopathy (n = 19), concentric left ventricular hypertrophy (18), and dilated cardiomyopathy (6). Mean ± SD left atrial-to-aortic diameter ratio (n = 39) was 2.55 ± 0.80. The most common thoracic radiographic findings were cardiomegaly, pleural effusion, and pulmonary edema. Median survival time (n = 24) was 165 days (range, 0 to 1,095 days). Eight of 24 cats lived for ≥ 1 year after a diagnosis of AF was made.Conclusions and Clinical Relevance—Results suggest that AF occurs primarily in older adult male cats with structural heart disease severe enough to lead to atrial enlargement. Atrial fibrillation in these cats was most commonly first detected when signs of decompensated cardiac disease were evident, but also was commonly identified as an incidental finding.

Abstract

Objective—To determine outcome of equids in the
western United States with clinical signs of West Nile
virus (WNV) infection and identify factors associated
with risk of death in infected equids.

Design—Cross-sectional study.

Animals—484 equids in Nebraska and Colorado.

Procedure—Owners of 484 equids with laboratoryconfirmed
West Nile virus infection in Nebraska and
Colorado were contacted by telephone, and a questionnaire
was used to obtain information on signalment,
management, clinical signs, date of disease
onset, duration of disease, WNV vaccination status,
and health status at the time of the interview.

Results—137 of 482 (28.4%) animals died or were
euthanatized. Ataxia, lethargy, muscle fasciculations,
and weakness were the most common clinical signs
of disease. Animals ≥ 3 years old were more likely to
die than were animals ≤ 2 years old. Unvaccinated
equids were twice as likely to die as were animals
that had been vaccinated at least once prior to the
onset of disease. Animals that were recumbent and
unable to rise were 78 times as likely to die as were
animals that never lost the ability to rise. Females
were 2.9 times as likely to die as males. Two hundred
seventy-one of 339 (79.9%) animals that survived
recovered fully; mean duration of disease for these
animals was 22.3 days.

Conclusions and Clinical Relevance—Among equids
with WNV infection, age, vaccination status, an inability
to rise, and sex were associated with the risk of
death. (J Am Vet Med Assoc 2004;225:267–274)

AbstractObjective—To estimate prevalence of and identify risk factors for fecalSalmonellashedding among hospitalized horses with signs of gastrointestinal tract disease.Design—Cross-sectional study.Animals—465 hospitalized horses with gastrointestinal tract disease.Procedure—Horses were classified as positive or negative for fecal Salmonella shedding during hospitalization by means of standard aerobic bacteriologic methods. The relationship between investigated exposure factors and fecalSalmonellashedding was examined by means of logistic regression.Results—The overall prevalence of fecalSalmonellashedding was 13%.Salmonellaserotype Newport was the most commonly isolated serotype (12/60 [20%]), followed by Anatum (8/60 [13%]), Java (13%), and Saint-paul (13%). Foals with gastrointestinal tract disease were 3.27 times as likely to be sheddingSalmonellaorganisms as were adult horses with gastrointestinal tract disease. Adult horses that had been treated with antimicrobial drugs prior to hospitalization were 3.09 times as likely to be sheddingSalmonellaorganisms as were adult horses that had not been treated with antimicrobial drugs prior to hospitalization. Adult horses that underwent abdominal surgery were 2.09 times as likely to be sheddingSalmonellaorganisms as were adult horses that did not undergo abdominal surgery.Conclusions and Clinical Relevance—Results suggest that a history of exposure to antimicrobial drugs prior to hospitalization and abdominal surgery during hospitalization were associated withSalmonellashedding in adult horses with gastrointestinal tract disease. Foals with gastrointestinal tract disease were more likely to shedSalmonellaorganisms than were adult horses with gastrointestinal tract disease. (J Am Vet Med Assoc2004;225:275–281)
Comparison of the standard predictive equation for calculation of resting energy expenditure with indirect calorimetry in hospitalized and healthy dogs

Published: December 2005

AbstractObjective—To determine the level of clinical agreement between 2 methods for the measurement of resting energy expenditure (REE).Design—Prospective case series.Animals—77 dogs.Procedure—Oxygen consumption (O2) and CO2production (CO2) were measured with an open-flow indirect calorimeter in healthy (n = 10) and ill (67) dogs. Measurements were collected at 3 time periods on 2 days. TheO2and theCO2measurements were then used to calculate the REE values.Results—Mean values of measured (MREE) and predicted (PREE) REEs in healthy dogs and a dog with medical illnesses or trauma were not significantly different. There was a significant difference on day 2 between the MREE and PREE in the group of dogs recovering from major surgery. More importantly, there was significant variation between the PREE and MREE on an individual-dog basis. The PREE only agreed to within ± 20% of the MREE in 51% to 57% of the dogs.Conclusions and Clinical Relevance—The level of agreement between these two methods for determining the 24-hour REE was poor in individual dogs. The level of disagreement between the 2 methods indicates that these methods may not be used interchangeably in a clinical setting. Measurement of REE by use of indirect calorimetry may be the only reliable method of determining REE in an individual ill or healthy dog. (J Am Vet Med Assoc2004;225:58–64)

AbstractObjective—To evaluate feasibility of performing laparoscopic-assisted placement of a jejunostomy feeding tube (J-tube) and compare complications associated with placement, short-term feedings, and medium-term healing with surgically placed tubes in dogs.Design—Prospective study.Animals—15 healthy mixed-breed dogs.Procedure—Dogs were randomly allocated to undergo open surgical or laparoscopic-assisted J-tube placement. Required nutrients were administered by a combination of enteric and oral feeding while monitoring for complications. Radiographic contrast studies documented tube direction and location, altered motility, or evidence of stricture.Results—Jejunostomy tubes were successfully placed in the correct location and direction in all dogs. In the laparoscopic group, the ileum was initially selected in 2 dogs, 2 dogs developed moderate hemorrhage at a portal site, and 2 J-tubes kinked during placement but were successfully readjusted postoperatively. All dogs tolerated postoperative feedings. All dogs developed minor ostomy site inflammation, and 1 dog developed bile-induced dermatitis at the ostomy site. Despite mild, transient neutrophilia, no significant difference was noted in WBC counts between groups. No dog had altered gastric motility or evidence of stricture, although the jejunopexy site remained identifiable in several dogs at 30 days.Conclusions and Clinical Relevance—Requirements for successful J-tube placement were met by use of a laparoscopic-assisted technique, and postoperative complications were mild and comparable to those seen with surgical placement. Laparoscopic-assisted J-tube placement compares favorably to surgical placement in healthy dogs and should be considered as an option for dogs requiring enterostomy feeding but not requiring a celiotomy for other reasons.
