Pet owner perspectives, motivators and concerns about veterinary biobanking.

Introduction: Veterinary biobanks store samples for future use and distribute samples to academic researchers and industry entities; however, informed consent provided by owners for pets contributing to biobanks can be complicated by limited understanding of goals, purpose, and logistics of biobanking.

Methods: This survey-based study aimed to gather feedback from pet owners on how they viewed allowing their pet to contribute to a veterinary biobank, with the goal of identifying opportunities to improve education, awareness of veterinary biobanking initiatives, and the consent processes. An electronic survey was distributed to a listserv of 2,119 pet owners and responses were received from 118 respondents (5.

Veterinary radiologic error rate as determined by necropsy.

A large-scale postmortem auditing of antemortem imaging diagnoses has yet to be accomplished in veterinary medicine. For this retrospective, observational, single-center, diagnostic accuracy study, necropsy reports for patients of The Schwarzman Animal Medical Center were collected over a 1-year period. Each necropsy diagnosis was determined to be either correctly diagnosed or discrepant with its corresponding antemortem diagnostic imaging, and discrepancies were categorized.

Prospective Evaluation of Low-Fat Diet Monotherapy in Dogs with Presumptive Protein-Losing Enteropathy.

For dogs with protein-losing enteropathy (PLE) and evidence of lymphangiectasia, the efficacy of low-fat diet as monotherapy or combined with prednisone remains poorly characterized. In this prospective, observational cohort study of 14 dogs with presumptive PLE and ultrasonographic evidence of lymphangiectasia, subjects were placed on various low-fat diets as monotherapy and prednisone was added if response was deemed inadequate. Dogs were assessed and scored at four recheck examinations across a 6 mo study period, including a final recheck ultrasound.

Objective: To report overall rate and type of complications and outcomes of cats with coxofemoral luxation managed with hip toggle stabilization (HTS), to compare rate of postoperative complications and outcomes of cats treated with ultrahigh-molecular-weight-polyethylene (UHMWPE) or nylon, and to identify risk factors for reluxation and non-excellent outcomes.

Study Design: Multi-institutional retrospective cohort study.

Sample Population: Forty-eight client-owned cats.

Canine Elbow Dysplasia: Medial Compartment Disease and Osteoarthritis.

Erosion of the articular cartilage of the medial compartment of the elbow (the humeroulnar articulation) secondary to incongruency associated with elbow dysplasia or traumatic injury has been termed, medial compartment disease. When nonsurgical strategies to manage osteoarthritis (OA) fail, surgical solutions may be warranted. Surgical strategies reduce pain through off-loading of the medial compartment by load-shifting osteotomies of the humerus or ulna.

Canine Elbow Dysplasia: Ununited Anconeal Process, Osteochondritis Dissecans, and Medial Coronoid Process Disease.

Elbow dysplasia is a major cause of front limb lameness in medium to large dog breeds. Underlying causes include ununited anconeal process, medial coronoid process disease, and osteochondritis dissecans. When a definitive diagnosis of elbow dysplasia is made, the surgeon can improve elbow function but cannot entirely prevent progression of osteoarthrosis.

Repeat balloon valvuloplasty for dogs with recurrent or persistent pulmonary stenosis.

Introduction/objectives: Pulmonary stenosis (PS) is a common congenital defect in the dog. Severe valvar PS can be treated with balloon valvuloplasty (BV) to reduce obstruction severity and improve clinical signs. Repeat BV is often unnecessary, as restenosis is uncommon.

MRI T2/STIR epaxial muscle hyperintensity in some dogs with intervertebral disc extrusion corresponds to histologic patterns of muscle degeneration and inflammation.

Magnetic resonance imaging hyperintensity on T2-weighted turbo SE and STIR sequences of the paraspinal musculature in canine patients being imaged for thoracolumbar intervertebral disc extrusion is frequently observed but poorly understood in veterinary medicine. The objective of this prospective analytical study was to describe the histopathology of muscle hyperintensity in dogs with thoracolumbar intervertebral disc extrusions and to determine if a relationship exists between the presence of this hyperintensity and various patient factors. Twenty privately owned dogs who underwent surgical decompression of intervertebral disc extrusions diagnosed on MRI were enrolled (10 normal "control or nonaffected cases" without MRI paraspinal musculature hyperintensity and 10 "affected cases" with hyperintensity).

Total hip replacement in dogs with contralateral pelvic limb amputation: A retrospective evaluation of 13 cases.

Objective: To report the clinical characteristics, surgical management, and medium-term outcomes of total hip replacement (THR) performed in dogs with previous contralateral pelvic limb amputation.

Animals: Thirteen client-owned dogs.

Study Design: Multi-institutional retrospective clinical study.

Coughing in Small Animal Patients.

Cough is one of the most common complaints in human medicine. In veterinary medicine cough is equally frequent and plays a significant role in an owner's perception of their pet's quality of life. In human and veterinary medicine, therapy for chronic cough is often ineffective.

DERMATITIS AND RHINOSINUITIS CAUSED BY SPECIES IN A CHINESE GORAL ().

Curvularia spp. are globally distributed saprophytic fungi, classified in the literature as dematiaceous, or darkly pigmented fungi. These fungi have been increasingly recognized as causing cutaneous, ocular, respiratory, and central nervous system infections in humans, but have been infrequently documented as pathogens in the veterinary literature.

Long-term radiographic appearance of a bioabsorbable biocomposite tibial tuberosity advancement cage implant.

Objective: To report the radiographic appearance of a bioabsorbable biocomposite tibial tuberosity advancement cage at least 1 year after implantation. Design Retrospective case series.

Methods: Medical records (February 2014-March 2015) of dogs receiving a biocomposite tibial tuberosity advancement cage were reviewed.

Minimally Invasive Osteosynthesis Techniques for Humerus Fractures.

A thorough knowledge of humeral anatomy is critical to performing minimally invasive techniques. Fluoroscopy, when available, is invaluable in optimizing fracture repair with minimally invasive techniques. Minimally invasive approaches decrease morbidity and allow an earlier return to function.

Unique Differences of Minimally Invasive Fracture Repair in the Feline.

As the saying goes, "cats are not small dogs." Throughout veterinary medicine history, most of the literature focus has been on the canine. Feline patients, however, now constitute a larger proportion of the pet population and are unique in many aspects.

Lidocaine for chemical cardioversion of orthodromic atrioventricular reciprocating tachycardia in dogs.

Background: Typical atrioventricular accessory pathways (APs) are composed of myocardial cells. They provide electrical connections between atria and ventricles separate from the normal conduction system. Accessory pathways can participate in a macroreentrant circuit resulting in orthodromic atrioventricular reciprocating tachycardia (OAVRT).

Impact of postoperative antibiotics on rates of infection and implant removal after tibial tuberosity advancement in 1,768 canine stifles.

Objective: To report infection rate, implant removal rate, and postoperative antibiotic therapy after tibial tuberosity advancement (TTA) in dogs.

Study Design: Retrospective study.

Animals: One thousand seven hundred sixty-eight stifles in 1,732 dogs.

The utility of intraoperative impression smear cytology of intracranial granular cell tumors: Three cases.

Two adult male dogs (a 7-year-old shorthaired Chihuahua and 14-year-old Shih Tzu) and one adult female dog (a 9-year-old Maltese) presented for evaluation of new-onset seizure activity. Magnetic resonance imaging of the brain demonstrated a large, poorly marginated T2-weighted hyperintense, and strong contrast enhancing extra-axial mass in each case. A surgical biopsy for histopathologic evaluation was elected in all cases, and intraoperative impression smears were successfully obtained.

Biomechanical Comparison of Four Methods of Fixation of a Polymeric Cranial Cruciate Ligament in the Canine Femur and Tibia.

Objective:  The aim of this study was to compare the biomechanical properties of four different methods of artificial cranial cruciate ligament fixation in canine cadaveric tibias and femurs.

Methods:  Femurs and tibias from skeletally mature large breed canine cadavers were assigned into four fixation groups: group 1, 4.5-mm interference screw (IS); group 2, 4.

Ex vivo preliminary investigation of radiographic quantitative assessment of cranial tibial displacement at varying degrees of canine stifle flexion with or without an intact cranial cruciate ligament.

Background: The presence of cranial tibial subluxation can aid in the detection of joint instability as a result of CrCL injury. Detection of cranial tibial subluxation has been described using the tibial compression test (TCT) and cranial drawer test (CDT); however, diagnosis of CrCL insufficiency by assessing cranial subluxation motion of the tibia is subjective and difficult to quantify accurately. The aim of this study was to investigate a measurement technique to assess the degree of cranial tibial displacement relative to the femoral condyles on mediolateral projection stifle radiographs at varying degrees of stifle flexion (90°, 110°, and 135°) in CrCL intact, partially, and completely transected conditions.
