Muscular metastatic neoplasia has been reported to be rare in domestic animals, however previous studies were based primarily on necropsy findings. The purpose of this retrospective study was to describe whole body computed tomography (CT) characteristics of confirmed muscular metastases in a cohort of dogs and cats presented for oncology evaluation. Medical records of 1201 oncology patients were reviewed. Included animals underwent pre and postcontrast whole body CT, and CT‐guided tru‐cut biopsy or fine needle aspiration of one or more metastatic lesions. Twenty‐one dogs and six cats met inclusion criteria, representing 2.08% of all canine oncology patients and 3.1% of all feline oncology patients. Mean age was 9.6 years. Postcontrast CT characteristics included well‐demarcated, oval‐to‐round lesions with varying enhancement patterns: ring enhancing (n = 16), heterogeneously enhancing (n = 8), or homogeneously enhancing (n = 5). Five animals showed concurrent and varying nodular patterns. In seven cases (five dogs and two cats), one single muscular nodule was observed. In 20 cases, two or more lesions were observed. In two cases, cardiac hypodense nodules were observed in the postcontrast CT, while appearing isodense in the precontrast study. Necropsy confirmed neoplasia in both of them. Locations of muscular metastases included epaxial/paraspinal muscles of the cervical, thoracic, and lumbar spine (n = 18), superficial muscles of the thoracic wall (n = 13), scapular/shoulder region (n = 3), hind limb (n = 3), and abdominal wall muscles (n = 1). Findings supported the use of pre and postcontrast whole body CT for oncologic staging in dogs and cats, especially for primary tumors characterized by a high metastatic rate.  相似文献

Diagnosis of Giardia infection in 14 calves   总被引：1，自引：0，他引：1  

G St Jean  Y Couture  P Dubreuil  J L Fréchette 《Journal of the American Veterinary Medical Association》1987,191(7):831-832

Fourteen calves, 12 days to 12 weeks old, were treated for diarrhea. Fecal examination for parasitologic, bacteriologic, or viral infection revealed Giardia in all calves; rotavirus and coronavirus were found in some calves. Thirteen affected calves were treated orally with dimetridazole (50 mg/kg of body weight, daily, for 5 days), with complete resolution of the diarrhea and elimination of the Giardia. Giardiasis should be considered as an etiologic agent of diarrhea in calves.  相似文献   

Effects of oral administration of meloxicam,carprofen, and a nutraceutical on thyroid function in dogs with osteoarthritis          下载免费PDF全文

The purpose of this study was to evaluate the effect of the administration of meloxicam; carprofen; and a slow-acting disease modifying osteoarthritis agent, that contains chondroitin sulfate, purified glucosamine, and manganese ascorbate (CS-G-M), on thyroid function in dogs. Forty-six healthy (except for osteoarthritis) euthyroid dogs were blindly assigned to 3 treatment groups: meloxicam, carprofen, and CS-G-M. Each group received the recommended dose of the drug for 60 days. Sixteen other osteoarthritic euthyroid dogs, which received a placebo, were used as a control group to validate the study. For all groups, blood samples were collected on days 0, 30, and 60 to evaluate the serum total and free thyroxine, and endogenous thyrotropin concentrations. There were no significant differences among the treatment groups at each time or within each group over a 60-day period for all parameters. Moreover, none of these values were within the hypothyroid range. Based on the results of this study, the administration of meloxicam, carprofen, and CS-G-M did not affect canine thyroid function evaluation.  相似文献   

Morbidity of purebred dogs in Denmark     

Proschowsky HF  Rugbjerg H  Ersbøll AK 《Preventive veterinary medicine》2003,58(1-2):53-62

Prevalences of diseases in purebred dogs are reported from a questionnaire study among members of the Danish Kennel Club (DKC) in 1997. The 4295 dogs in the study represented 24 breeds and 16 breed groups. Sixty percent of the dogs had at least one disease-event during their lifetime with a median of 2 and a maximum of 11. Diseases of the skin were the most-frequent (13.6%) followed by eye diseases (13.2%), accidents (12.6%) and diseases of the ear (12.6%). The prevalences of five diseases differed significantly between the breeds (diseases of the skin, eyes, ears, respiratory and skeletal systems). Males had significantly higher prevalences of respiratory diseases, skeletal diseases and diseases of the mouth and teeth. Tumours and diseases of the urinary system were most prevalent in females. Gender- and breed-specific prevalences are reported for the most-frequent diseases.  相似文献   

Risk factors associated with interdog aggression and shooting phobias among purebred dogs in Denmark     

Rugbjerg H  Proschowsky HF  Ersbøll AK  Lund JD 《Preventive veterinary medicine》2003,58(1-2):85-100

The prevalence of behaviour problems is reported from a questionnaire study among members of the Danish Kennel Club (DKC). In total, 4359 dog owners were included in the analyses. With logistic regression, we analysed four behaviour problems: dominance towards the owner, interdog dominance aggression, separation anxiety and shooting phobia. Compared to Labrador Retrievers, the following breeds and breed groups had higher odds of being reported to have interdog dominance aggression: Belgian Sheepdogs, Dachshunds, Dalmatians, German Shepherds, Hovawarts, Pinschers, Rottweilers, Scent dogs and Spitz dogs. Poodles, retrieving/flushing dogs, Sheepdogs, Spitz dogs and terriers had higher odds of shooting phobia. The odds of interdog dominance aggression were higher among dogs owned by younger dog owners compared to dogs owned by older dog owners. Dogs living in the capital area of Copenhagen had increased odds of interdog dominance aggression as compared to dogs living in other parts of Denmark. Dogs belonging to owners with limited knowledge of the breed before acquiring the dog had higher odds of interdog dominance aggression. Dogs attending obedience training classes had reduced odds of shooting phobia. Dogs belonging to dog breeders had reduced odds of being reported to have the investigated behaviour problems.  相似文献   

Association between initial systolic blood pressure and risk of developing a uremic crisis or of dying in dogs with chronic renal failure     

Jacob F  Polzin DJ  Osborne CA  Neaton JD  Lekcharoensuk C  Allen TA  Kirk CA  Swanson LL 《Journal of the American Veterinary Medical Association》2003,222(3):322-329

OBJECTIVE: To determine whether high systolic blood pressure (SBP) at the time of initial diagnosis of chronic renal failure in dogs was associated with increased risk of uremic crisis, risk of dying, or rate of decline in renal function. DESIGN: Prospective cohort study. ANIMALS: 45 dogs with spontaneous chronic renal failure. PROCEDURE: Dogs were assigned to 1 of 3 groups on the basis of initial SBP (high, intermediate, low); Kaplan-Meier and Cox proportional hazards methods were used to estimate the association between SBP and development of a uremic crisis and death. The reciprocal of serum creatinine concentration was used as an estimate of renal function. RESULTS: Dogs in the high SBP group were more likely to develop a uremic crisis and to die than were dogs in the other groups, and the risks of developing a uremic crisis and of dying increased significantly as SBP increased. A greater decrease in renal function was observed in dogs in the high SBP group. Retinopathy and hypertensive encephalopathy were detected in 3 of 14 dogs with SBP > or = 180 mm Hg. Systolic blood pressure remained high in 10 of 11 dogs treated with antihypertensive drugs. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggested that initial high SBP in dogs with chronic renal failure was associated with increased risk of developing a uremic crisis and of dying. Further studies are required to determine whether there is a cause-and-effect relationship between high SBP and progressive renal injury and to identify the risks and benefits of antihypertensive drug treatment.  相似文献

Sampling for the incidence of aphid-transmitted viruses in snap bean     

Shah DA  Dillard HR  Nault BA 《Phytopathology》2005,95(12):1405-1411

ABSTRACT Data collected in 2002 and 2003 on Alfalfa mosaic virus and Cucumber mosaic virus incidences of infection in commercial snap bean fields in New York State were used to develop relationships between disease incidence (p(low)) and sample size while accounting for the inherent spatial aggregation of infected plants observed with these two viruses. For a plan consisting of 300 sampled plants (N = 60 quadrats, n = 5 plants per quadrat), estimating p(low) from the incidence of positive groups (p(high); testing of N = 60 grouped samples) provides the same precision in p(low) as testing 200 plants individually, up to about p(low) = 0.2. Above that, the confidence interval width for p(low) obtained via group testing becomes markedly larger than the width obtained by testing individual plants. Our results suggest using group testing until p(high) is in the range [0.35, 0.59], which corresponds to p(low) in [0.1, 0.2]. Results indicate that group testing can be more economical than the testing of individual plants without loss of precision, at lower incidences of infection. The approach presented provides a general framework for sampling and the estimation of incidence of other aphid-transmitted viruses in snap bean.  相似文献   

Taxon-dependent Scaling: Beetles,Birds, and Vegetation at Four North American Grassland Sites     

Jonathan?M.?BossenbroekEmail author  Helene?H.?Wagner  John?A.?Wiens 《Landscape Ecology》2005,20(6):675-688

Because organisms respond to the environment at different scales, it is important to develop ways of determining the appropriate scales for a specific ecological process and organism. We consider whether the relative importance of different scales is associated with organism mobility, and whether this relationship is independent of landscape characteristics. We observed abundances of particular species for vascular plants, ground-dwelling beetles and breeding birds along eight 2-km transects of 40 sampling stations each, distributed over four sites along the regional gradient from shortgrass steppe in central Colorado to tallgrass prairie in central Kansas. For each transect and taxonomic group, the relative importance of factors measured at the trap scale (1 m; soil texture and hardness, vegetation height, bare ground), at the local scale (10 m; density of shrubs and cacti) and at the landscape scale (30 m; Landsat 7 TM spectral bands, slope and elevation) was assessed using hierarchical canonical variance partitioning with forward selection of explanatory variables. Plant, beetle and bird community composition was explained by environmental factors measured at all three scales. Factor influence was more consistent between transects and between plants and beetles for the more homogeneous landscapes of the shortgrass steppe than for the more heterogeneous landscapes of the tallgrass prairie. We conclude that, independent of the mobility of a taxonomic group, factors at several scales are important in explaining community composition. The importance of different scales shifts along a regional gradient, and the variability between sites is high even for nearby sites.  相似文献
