Retrospective analysis of radiographic signs in feline pleural effusions to predict disease aetiology.

Background: The objectives of the study were to determine the prevalence of underlying conditions causing pleural effusion in cats and to calculate the positive predictive values, negative predictive values, sensitivity and specificity of radiographic signs to predict aetiology of the pleural fluid.

Methods: Data from 148 cats with pleural effusion and diagnosed with known aetiologies were retrospectively analysed. Sixty one cats had thoracic radiographs evaluated by consensus through pre-defined radiographic signs by two radiologists blinded to the diagnoses.

Shear-wave elastography for the assessment of liver fibrosis in liver transplant recipients treated for hepatitis C virus recurrence.

Objectives: Direct-acting antiviral agents have revolutionized hepatitis C therapy, and are also found to be effective in the liver transplant setting. The extent of liver fibrosis influences patient management and is used to monitor therapeutic effects. Shear-wave elastography (SWE) is a relatively new imaging-based method that has not yet been studied extensively in liver transplant patients.

Sonographic features of gastrointestinal lymphoma in 15 dogs.

Objectives: The purpose of this study is to describe the sonographic appearance of lymphoma of the gastrointestinal tract in dogs.

Method: A retrospective review was conducted and patients with gastrointestinal lymphoma diagnosed by histopathology (including immunohistochemistry, where available) or cytology that had an abdominal ultrasound were included.

Results: Four of 15 (26·7%) cases with histopathologically confirmed lymphoma exhibited no sonographic abnormalities.

Clotrimazole and enilconazole distribution within the frontal sinuses and nasal cavity of nine dogs with sinonasal aspergillosis.

Objectives: Multiple topical treatments are often required for clinical cure of mycotic rhinosinusitis in dogs. The objective of this study was to describe the distribution and retention of enilconazole and clotrimazole solutions using a temporary trephination protocol.

Methods: Nine client-owned dogs diagnosed with mycotic rhinosinusitis between March 2008 and December 2009 were prospectively enrolled and were sequentially allocated to receive treatment with either clotrimazole (1% in polyethylene glycol) or enilconazole (10% solution), after imaging and rhinoscopic assessment.

Computed tomography diagnosis of eight dogs with brain infarction.

Objective: Medical records of eight dogs presenting with acute onset of neurological signs and a diagnosis of brain infarction as determined by computed tomography (CT) imaging were reviewed.

Design: Retrospective single-centre case review.

Results: Ischaemic infarction in the territory of the rostral cerebellar artery was identified in three spaniel-breed dogs.
