Ultrasonography and digital radiography findings in sheep with clinical disease associated with small ruminant lentivirus infection.

Digital radiography and ultrasonographic images were used in this case series to evaluate 4 ewes from a single flock for chronic weight loss and ill-thrift. On examination, all displayed tachypnea, dyspnea, coughing, and normothermia with abnormal thoracic auscultations. Three of the 4 animals were diagnosed with chronic respiratory disease associated with Maedi-visna (MV) infection confirmed serologic testing.

Computed tomography evaluation of proposed implant corridors in canine thoracic vertebrae.

Objective: Identify acceptable implant corridors in the normal canine thoracic vertebrae (T) from T1 to T9.

Study Design: Retrospective study.

Sample Population: Computed tomographic (CT) studies of normal canine thoracic spines (n = 39).

Influence of plate type and placement on the immobilization of bilateral equine mandibular osteotomies: Ex vivo study.

Objective: To determine the influence of plate fixation (locking or dynamic compression) and the site of application (ventral [V] or ventrolateral [VL]) on the resistance to bending of transverse mandibular fractures.

Study Design: Ex vivo, simple randomized study.

Sample Population: Mandibles harvested from adult equine cadavers (n = 18).

SINGLE-SHOT TURBO SPIN ECHO PULSE SEQUENCE FINDINGS IN DOGS WITH AND WITHOUT PROGRESSIVE MYELOMALACIA.

Progressive myelomalacia is an uncommon type of ischemic, hemorrhagic spinal cord infarction. Diagnosis can be difficult, but prompt recognition is important. We hypothesized that cerebrospinal fluid signal attenuation on magnetic resonance (MR) images would be more extensive in dogs that developed progressive myelomalacia vs.

IATROGENIC MICROCHIP ARTERIAL EMBOLISM IN A CHILEAN FLAMINGO (PHOENICOPTERUS CHILENSIS).

Aberrant microchip migration has been reported in domestic animal species, but in most cases, this migration is atraumatic to the patient. Reports of microchip-associated trauma and sarcoma development also have been reported in a variety of mammal species. This report describes accidental arterial microchip insertion causing obstruction of the iliac artery in a Chilean flamingo (Phoenicopterus chilensis).

COMPARISON OF FLUOROSCOPY AND COMPUTED TOMOGRAPHY FOR TRACHEAL LUMEN DIAMETER MEASUREMENT AND DETERMINATION OF INTRALUMINAL STENT SIZE IN HEALTHY DOGS.

Tracheal collapse is a progressive airway disease that can ultimately result in complete airway obstruction. Intraluminal tracheal stents are a minimally invasive and viable treatment for tracheal collapse once the disease becomes refractory to medical management. Intraluminal stent size is chosen based on the maximum measured tracheal diameter during maximum inflation.

Successful medical treatment of an orbital osteoma in a dog.

A 6-year-old neutered male German Shepherd-mixed breed with a 2-month history of bilateral conjunctival hyperemia, epiphora, and a firm, slowly progressive swelling of the medial canthal region of the left eye (OS) was examined. Ophthalmic examination OS revealed a firm and smooth mass, extending from the medial canthus toward the medial orbital wall. Indirect ophthalmoscopy revealed indentation of the nasal part OS, which corresponded to the position of the orbital mass.

Retroperitoneal pyogranulomatous and fibrosing inflammation secondary to fungal infections in two dogs.

Case Descriptions: A 4-year-old spayed female Golden Retriever (dog 1) was examined because of acute edema and erythema in the left hind limb and an inguinal mass, and a 5-year-old female Jack Russell Terrier (dog 2) was examined because of a recurring retro-peritoneal mass.

Clinical Findings: Dog 1 had an edematous, hyperemic left hind limb with a fixed inguinal mass. Monocytic neutrophilic leukocytosis and hypoalbuminemia were detected.

Replacing the enzyme alpha-L-iduronidase at birth ameliorates symptoms in the brain and periphery of dogs with mucopolysaccharidosis type I.

Mucopolysaccharidosis type I (MPS I) is a lysosomal storage disease caused by loss of activity of α-l-iduronidase and attendant accumulation of the glycosaminoglycans dermatan sulfate and heparan sulfate. Current treatments are suboptimal and do not address residual disease including corneal clouding, skeletal deformities, valvular heart disease, and cognitive impairment. We treated neonatal dogs with MPS I with intravenous recombinant α-l-iduronidase replacement therapy at the conventional 0.

Normal canine brain maturation at magnetic resonance imaging.

The normal neonatal canine brain exhibits marked differences from that of the mature brain. With development into adulthood, there is a decrease in relative water content and progressive myelination; these changes are observable with magnetic resonance imaging (MRI) and are characterized by a repeatable and predictable time course. We characterized these developmental changes on common MRI sequences and identified clinically useful milestones of transition.

Electrocardiography-guided and retrospective analysis of central venous catheter placement in the dog.

Objective: To compare the success rates of central venous catheter placement (CVCP) in dogs using electrocardiograph (ECG)-guided and external landmark ('blind') techniques. To report success rates determined retrospectively of CVCPs in dogs using external landmarks at a tertiary referral institution.

Study Design: Prospective blinded comparison of techniques.

A vascular hamartoma arising from the cervical spine of a cat.

A 15-month-old cat presented for evaluation of worsening generalized proprioceptive ataxia. Computed tomography of the cervical spine revealed the presence of a compressive extradural bony mass involving the dorsal aspect of C1. Surgical exploration and debulking of the mass was performed.

The relationship between limb function and radiographic osteoarthrosis in dogs with stifle osteoarthrosis.

Objective: To evaluate the relationship between limb function and radiographic evidence of stifle osteoarthrosis (OA) in dogs.

Study Design: The relationship between force platform data and radiographic OA score was evaluated on 2 separate days using regression analysis. Interday variation was also assessed.
