Infarctive encephalopathy in zoo-housed gibbons in North America.

Progressive neurologic signs without a known underlying etiology have been observed in managed gibbon populations housed at institutions in North America. In 2018, the Gibbon Species Survival Plan initiated a veterinary survey to evaluate clinical histories among gibbons displaying neurologic signs. The clinical results of this survey as well as the results of a centralized histologic review of brain samples from 5 species of managed gibbons displaying neurologic signs are outlined here.

Computed tomographic features of exocrine pancreatic carcinomas in dogs and cats.

Exocrine pancreatic carcinomas are uncommon in dogs and cats, and diagnosis with diagnostic imaging can be challenging. This retrospective, multi-institutional, descriptive study was performed to evaluate the CT features of exocrine pancreatic carcinomas. The CT examinations of 18 dogs and 12 cats with exocrine pancreatic carcinomas diagnosed by cytology or histopathology were reviewed.

Untargeted metabolomic profiles reveal widespread metabolic perturbations and identify candidate biomarkers in aminoaciduric canine hypoaminoacidemic hepatopathy syndrome.

Objective: To identify metabolites and metabolic pathways affected in dogs with aminoaciduric canine hypoaminoacidemic hepatopathy syndrome (ACHES) compared to healthy control (CON) dogs of similar ages and breeds. To improve our understanding of ACHES pathophysiology and identify novel candidate biomarkers associated with ACHES.

Animals: A prospective case-control study.

Novel genomic prognostic biomarkers for dogs with cancer.

Background: Growing evidence from dogs and humans supports the abundance of mutation-based biomarkers in tumors of dogs. Increasing the use of clinical genomic diagnostic testing now provides another powerful data source for biomarker discovery.

Hypothesis: Analyzed clinical outcomes in dogs with cancer profiled using SearchLight DNA, a cancer gene panel for dogs, to identify mutations with prognostic value.

The most common types of uroliths larger than 1 mm are readily visible and accurately measured in an in vitro setting mimicking the canine abdomen using digital radiography.

Abdominal radiography is an important diagnostic to detect uroliths. Cystine and urate uroliths were historically characterized as nonmineral opaque on survey radiographs. However, recent research and clinical observations indicate that pure urate and cystine uroliths may be detected with digital radiography.

Randomised trial evaluating chemotherapy alone or chemotherapy and a novel monoclonal antibody for canine T-cell lymphoma: A multicentre US study.

Background: Canine peripheral nodal T-cell lymphoma is considered chemotherapy resistant and carries a relatively poor prognosis. Prospective evaluations reporting the impact of chemotherapy on progression-free survival (PFS) and overall survival time for dogs with T-cell lymphoma are lacking. This study examined the impact of L-CHOP (L-asparaginase, doxorubicin, cyclophosphamide, vincristine, prednisone) chemotherapy or L-CHOP in combination with AT-005, a US Department of Agriculture-licensed caninised monoclonal antibody, on PFS and response rates in dogs with clinical intermediate- and high-grade peripheral nodal T-cell lymphoma.

Body mapping chart for estimation of percentage of body surface area in mesocephalic dogs.

Objective: To create a chart for estimating body surface area (BSA) for use in canine burn victims, similar to the human Rule of Nines.

Design: Prospective study, from 2016 to 2017.

Setting: University teaching hospital.

A Single Base Insertion in Causing Hemophilia B in a Family of Newfoundland-Parti Standard Poodle Hybrid Dogs.

Hemophilia B is an x-linked recessive hereditary coagulopathy that has been reported in various species. We describe a male Newfoundland-Parti Standard Poodle hybrid puppy and its family with hemophilia B from clinical manifestations to the molecular genetic defect. The index case presented for dyspnea was found to have a mediastinal hematoma, while surgical removal and transfusion support brought some relief, progressive hematoma formations led to humane euthanasia.

Biocompatibility of allogenic canine fascia lata: In vitro evaluation and small case series.

Objective: To evaluate the biocompatibility of canine fascia lata (FL) in vitro and after FL allograft implantation in dogs with clinical disease.

Study Design: In vitro experiment and small case series.

Sample Population: Six dogs treated with allogenic freeze-dried FL.

Long-Term Treatment and Survival in Three Apparently Immunocompetent Dogs with Disseminated Fungal Infection Caused by Phialosimplex caninus.

Disseminated fungal infections cause morbidity and mortality in dogs. The prognosis varies depending on the infecting agent. Phialosimplex caninus is a recently recognized type of hyalohyphomyces.

Acquired tricuspid valve stenosis associated with two ventricular endocardial pacing leads in a dog.

Acquired tricuspid valve stenosis (TVS) is a rare complication of endocardial pacing lead implantation in humans that has only been described once previously in the veterinary literature in a dog with excessive lead redundancy. A 12 yr old terrier presented with right-sided congestive heart failure 6 mo after implantation of a second ventricular endocardial pacing lead. The second lead was placed due to malfunction of the first lead, which demonstrated abnormally low impedance.

Use of enoxaparin in dogs with primary immune-mediated hemolytic anemia: 21 cases.

Objective: To describe the complications and frequency of thrombosis associated with the use of enoxaparin, a low molecular weight heparin, in dogs with primary immune-mediated hemolytic anemia (IMHA).

Design: Retrospective case series.

Setting: Two privately owned veterinary referral hospitals.

Left atrial rupture secondary to myxomatous mitral valve disease in 11 dogs.

The purpose of this retrospective study was to evaluate the long-term outcome in dogs with left atrial rupture secondary to myxomatous mitral valve disease. Eleven client-owned dogs met the inclusion criteria for the study. Median age was 11.

Pamidronate disodium for palliative therapy of feline bone-invasive tumors.

This study sought to quantify in vitro antiproliferative effects of pamidronate in feline cancer cells and assess feasibility of use of pamidronate in cats by assessing short-term toxicity and dosing schedule in cats with bone-invasive cancer. A retrospective pilot study included eight cats with bone invasive cancer treated with intravenous pamidronate. In vitro, pamidronate reduced proliferation in feline cancer cells (P < 0.

Constrictive pericarditis following surgical repair of a peritoneopericardial diaphragmatic hernia in a cat.

A 4-year-old female spayed domestic longhair cat was referred for dyspnea. Further diagnostics revealed severe pleural effusion and a peritoneopericardial diaphragmatic hernia (PPDH). Following surgical correction of the PPDH the pleural effusion persisted.

Presumptive immune-mediated thrombocytopenia secondary to massive Africanized bee envenomation in a dog.

Objective: To describe a case of immune-mediated thrombocytopenia (IMT) after massive Africanized bee envenomation in a dog.

Isolation of methicillin-resistant Staphylococcus lugdunensis in a dog with endocarditis.

A 4-year-old male castrated Borzoi dog presented on referral for evaluation of pleural effusion, ventricular arrhythmias, and suspected dilated cardiomyopathy. Echocardiogram identified several masses along the chordae tendineae, as well as a long the annulus of the mitral valve. A blood culture was positive for methicillin resistant Staphylococcus lugdunensis.

Adult-onset nemaline myopathy in a dog presenting with persistent atrial standstill and primary hypothyroidism.

A nine-year-old neutered female mixed breed dog presented for evaluation following a five-day history of lethargy, inappetence, weakness, abdominal distension and generalised muscle atrophy. Persistent vatrial standstill with a junctional rhythm was identified on electrocardiogram. Echocardiogram identified moderate dilation of all cardiac chambers and mild thickening of the mitral and tricuspid valves.
