Creation and Implementation of a Blood Smear Simulation Model.

Being able to prepare a diagnostic blood smear for evaluation is an essential skill for veterinary practitioners. While this basic technique can be demonstrated via videos or illustrations, it can only be learned through practice and with feedback. With the necessity for virtual learning experiences during the COVID-19 pandemic, a model was developed and paired with an online module to facilitate at home instruction and practice of blood smear preparation.

Elevated serum gamma-glutamyltransferase activity and immunohistochemistry in two dogs with renal carcinoma.

During a 3-year time period, a 15-year-old male castrated Terrier mix (dog 1) and a 6-year-old female spayed Labrador Retriever (dog 2) presented to the North Carolina State Veterinary Hospital with similar blood work abnormalities and no significant physical examination findings. A CBC, chemistry panel, and urinalysis performed on both dogs were relatively unremarkable, other than a marked increase in serum gamma-glutamyltransferase (GGT) activity. Through imaging, both patients were diagnosed with a renal mass, and histopathology of both masses revealed a carcinoma.

Diagnostic utility of the total nucleated cell count for differentiation of septic and sterile peritoneal effusions in dogs.

Background: Rapid and accurate diagnosis of septic peritonitis is critical for initiating appropriate medical and surgical management.

Objectives: The aim of this study was to determine the diagnostic utility of the total nucleated cell count (TNCC), absolute neutrophil count, neutrophil percentage, and total protein (TP) to distinguish septic versus non-septic peritoneal effusions in dogs.

Methods: Electronic medical records were retrospectively searched for peritoneal fluid samples from 2008 to 2018 and classified as septic or non-septic based on bacterial culture and/or cytology results.

Osteosarcoma of the wing in a sulfur-crested cockatoo.

A 26-year-old female sulfur-crested cockatoo (Cacatua galerita) was evaluated for vocalizing through the night and extending her right wing. Physical examination revealed a large, firm mass extending from the humerus to the distal aspect of the elbow. Computed tomography confirmed a large aggressive mass of the right distal humerus with a large soft tissue component, severe osteolysis, and adjacent periosteal proliferation.

Eosinophilic pericardial effusion and pericarditis in a cat.

Case Summary: A 10-year-old domestic shorthair cat presented for lethargy, anorexia and labored breathing. Significant pleural and pericardial effusions prompted thoracocentesis and pericardiocentesis. Cytologic evaluation of the pericardial effusion revealed a highly cellular hemorrhagic, eosinophilic (12%) effusion, with many markedly atypical suspected mesothelial cells, interpreted as concerning for neoplasia.
