The use of autologous skeletal muscle progenitor cells for adjunctive treatment of presumptive urethral sphincter mechanism incompetence in female dogs.

Background: Urethral sphincter mechanism incompetence (USMI) is a common problem in female dogs, but some dogs fail to achieve continence with standard treatment. Urethral submucosal injection of autologous skeletal muscle progenitor cells (skMPCs) previously has been shown to restore urethral function in a canine model of USMI.

Hypothesis/objective: To determine if urethral submucosal injection of skMPC alters continence in dogs with USMI that had previously failed standard medical management.

Antimicrobial Activity of Ceftiofur and Penicillin With Gentamicin Against Escherichia coli and Streptococcus equi Subspecies zooepidemicus in an Ex Vivo Model of Equine Postpartum Uterine Disease.

The use of antimicrobials for the management of equine uterine disease is commonplace, with antibiotic selection generally based on empirical evidence or in vitro sensitivity results. However, the potential disconnect between these laboratory results and clinical efficacy in the mare raises concern for antibiotic failure and subsequent development of resistant organisms. In this work, we attempt to bridge this gap by using an ex vivo model of the equine postpartum uterus to quantitatively evaluate the antimicrobial activity of two commonly used antibiotic treatments in the mare (ceftiofur and penicillin with gentamicin).

Retrospective analysis of the effect of acid-suppressant therapy on clinicopathologic parameters of cats with chronic kidney disease.

Objectives The aim was to retrospectively evaluate the effects of acid-suppressant therapy in a population of cats with chronic kidney disease (CKD). The study objectives were to evaluate the effects of acid-suppressant therapy on clinicopathologic variables and progression of CKD over time. Methods The databases of two institutions were searched over an 11 year time span for cats fitting inclusion criteria for CKD.

Gait scoring in dogs with thoracolumbar spinal cord injuries when walking on a treadmill.

Background: An inexpensive method of generating continuous data on hind limb function in dogs with spinal cord injury is needed to facilitate multicentre clinical trials. This study aimed to define normal fore limb, hind limb coordination in dogs walking on a treadmill and then to determine whether reliable data could be generated on the frequency of hind limb stepping and the frequency of coordinated stepping in dogs with a wide range of severities of thoracolumbar spinal cord injury.

Results: Sixty-nine neurologically normal dogs of different body sizes including seven lame dogs were videotaped walking on the treadmill without prior training and all used the lateral gait of right fore, left hind, left fore, right hind (RF-LH-LF-RH).

Canine hereditary ataxia in old english sheepdogs and gordon setters is associated with a defect in the autophagy gene encoding RAB24.

Old English Sheepdogs and Gordon Setters suffer from a juvenile onset, autosomal recessive form of canine hereditary ataxia primarily affecting the Purkinje neuron of the cerebellar cortex. The clinical and histological characteristics are analogous to hereditary ataxias in humans. Linkage and genome-wide association studies on a cohort of related Old English Sheepdogs identified a region on CFA4 strongly associated with the disease phenotype.

Genome-wide linkage study of atopic dermatitis in West Highland White Terriers.

Background: Canine atopic dermatitis (AD) is a common, heritable, chronic allergic skin condition prevalent in the West Highland White Terrier (WHWT). In canine AD, environmental allergens trigger an inflammatory response causing visible skin lesions and chronic pruritus that can lead to secondary bacterial and yeast infections. The disorder shares many of the clinical and histopathological characteristics of human AD and represents an animal model of this disorder that could be used to further elucidate genetic causes of human AD.

The prevalence of albuminuria in dogs and cats in an ICU or recovering from anesthesia.

Objective: To evaluate the prevalence of albuminuria in dogs and cats admitted to the ICU or recovering from an anesthetic event.

Design: Prospective clinical study over a 10-week period in 2003.

Setting: Veterinary teaching hospital.

The use of pooled vs serial urine samples to measure urine protein:creatinine ratios.

Background: Evaluation of serial urine protein:creatinine (UPC) ratios is important in prognosticating chronic kidney disease and monitoring response to therapeutic interventions. Owing to random biologic variation in dogs with stable glomerular proteinuria, multiple determinations of UPC ratios often are recommended to reliably assess urine protein loss. This can be cost-prohibitive.

Evaluation of perinuclear anti-neutrophilic cytoplasmic autoantibodies as an early marker of protein-losing enteropathy and protein-losing nephropathy in Soft Coated Wheaten Terriers.

Objective: To evaluate perinuclear anti-neutrophilic cytoplasmic autoantibody (pANCA) status in Soft Coated Wheaten Terriers (SCWTs) and SCWT-Beagle crossbred dogs and to correlate pANCA status of dogs with clinicopathologic variables of protein-losing enteropathy (PLE), protein-losing nephropathy (PLN), or both.

Animals: 13 SCWTs and 8 SCWT-Beagle crossbred dogs in a research colony and a control group comprising 7 dogs with X-linked hereditary nephropathy and 12 healthy SCWTs > 9 years old.

Procedures: Samples were obtained from dogs in the research colony every 6 months.

Recovery of pelvic limb function in dogs following acute intervertebral disc herniations.

Chondrodystrophoid breeds of dog are prone to explosive herniation of mineralized disc material into the thoracolumbar spinal canal. The resulting acute spinal cord injury may represent an excellent spontaneous model of acute traumatic spinal cord injury. The aims of this study were to quantify the recovery of dogs following acute disc herniations, to evaluate external factors that influence recovery, and to identify a group of dogs suitable for use in clinical trials on neuroprotective drugs.

Long-term functional outcome of dogs with severe injuries of the thoracolumbar spinal cord: 87 cases (1996-2001).

Objective: To determine long-term (> 6 months) outcome of dogs with paraplegia and loss of hind limb deep pain perception (DPP) resulting from intervertebral disk herniation or trauma.

Design: Retrospective study.

Animals: 87 dogs.
