High-frequency ultrasound biomicroscopy findings of the skin of dogs with atopic dermatitis.

Background: The high-frequency ultrasonographic appearance of skin of dogs with atopic dermatitis (cAD) has not been described.

Objectives: To compare high-frequency ultrasonographic findings among lesional, macroscopically nonlesional skin of dogs with cAD, and the macroscopically nonlesional skin of healthy dogs. Additionally, to determine whether there is any correlation between the ultrasonographic findings in lesional skin and local Canine Atopic Dermatitis Extent and Severity Index, 4th iteration (CADESI-04) or its domains (erythema, lichenification, excoriations/alopecia).

Low-field magnetic resonance imaging characteristics of multifocal vertebral lesions in dogs.

Background: There is a lack of information regarding magnetic resonance imaging (MRI) features of polyostotic vertebral lesions in dogs. The aim of this retrospective study was to identify and differenciate low-field MRI features of aggressive versus benign multifocal vertebral diseases in dogs.

Methods: MRI examinations from 49 dogs with polyostotic vertebral lesions were reviewed.

Low Field MRI Measurements of the Normal Canine Trigeminal Nerve.

There is no available measuring protocol and reference range for the normal canine trigeminal nerve. This can be problematic in cases of suspected bilateral trigeminal neuropathy since contralateral nerves cannot be a usefully compared. Trigeminal nerves and brain measurements were retrospectively assessed via multiplanar reconstruction (MPR) of 3DT1 post-contrast MR sequences from 137 dogs with no signs or diagnosis of trigeminal disease.

Convergence-Retraction Nystagmus in a Dog With Presumptive Ischemic Encephalopathy Following Acute Cervicothoracic Myelopathy.

A 6.5-year-old male neutered Trailhound was admitted for hyperacute, nonprogressive, left-sided hemiparesis. Physical and neurologic examination revealed nonpainful, left-sided poorly ambulatory hemiparesis, decreased left-sided postural reactions and thoracic limbs hyporeflexia.

Ultrasonographic findings in cats with acute kidney injury: a retrospective study.

Objectives: The aims of the study were to identify the ultrasonographic findings in cats with acute kidney injury (AKI) and to assess whether they had prognostic value.

Methods: This was a descriptive case series. A search of the computerised records of the Queen Mother Hospital for Animals (Hatfield, UK) was performed for cats presenting with AKI between 2007 and 2016.

ASSOCIATIONS BETWEEN DUAL-PHASE COMPUTED TOMOGRAPHY FEATURES AND HISTOPATHOLOGIC DIAGNOSES IN 52 DOGS WITH HEPATIC OR SPLENIC MASSES.

Ability to noninvasively differentiate malignant from nonmalignant abdominal masses would aid clinical decision making. The aim of this retrospective, cross-sectional study was to identify features in dual-phase computed tomographic (CT) studies that could be used to distinguish malignant from nonmalignant hepatic and splenic masses in dogs. Medical records were searched for dogs that had an abdominal dual-phase CT examination, a hepatic or splenic mass, and subsequent histopathologic diagnosis.

Studying Cat (Felis catus) Diabetes: Beware of the Acromegalic Imposter.

Naturally occurring diabetes mellitus (DM) is common in domestic cats (Felis catus). It has been proposed as a model for human Type 2 DM given many shared features. Small case studies demonstrate feline DM also occurs as a result of insulin resistance due to a somatotrophinoma.

Comparison of computed tomographic and pathologic findings in 17 dogs with primary adrenal neoplasia.

The CT appearance of canine adrenal masses has been reported, but associations between imaging features and pathologic features of these lesions have not been investigated in detail. The purpose of this study was to test associations between different types of adrenal neoplasia and their CT and pathologic features. A retrospective cross-sectional study was performed and inclusion criteria were histologic diagnosis of primary adrenal neoplasia, contrast-enhanced CT examination of the abdomen and surgical resection of the mass or necropsy examination.

High-frequency ultrasound biomicroscopy of the normal canine haired skin.

Background: The ultrasonographic appearance of the normal canine haired skin examined using high-frequency ultrasonography has not been described.

Hyposthesis/objectives: To describe the echogenicity of normal canine haired skin using high-frequency (50 MHz) ultrasonography and to compare ultrasonographic with histological measurements of skin thickness using snap-frozen tissue biopsy samples.

Animals: Ten normal healthy beagle dogs.

Computed tomographic signs of acromegaly in 68 diabetic cats with hypersomatotropism.

In order to describe the signs of acromegaly in cats, a case-control study was done based on computed tomography (CT) scans of the heads of 68 cats with hypersomatotropism and 36 control cats. All cats with a diagnosis of hypersomatotropism had diabetes mellitus, serum insulin-like growth factor-1 >1000 ng/ml and a pituitary mass. Measurements of bones and soft tissues were done by two independent observers without knowledge of the diagnosis.

Mast cell morphometry and densitometry in experimental skin wounds treated with a gel containing adelmidrol: a placebo controlled study.

The role of skin mast cells (MCs) in wound healing has been extensively investigated. The present study was designed to examine the effect of the aliamide adelmidrol on MCs during healing of experimental cutaneous wounds. Adelmidrol gel or the vehicle alone was applied 3 times daily on 5-mm punch biopsy wounds created on the thoracolumbar skin of 10 dogs.

Veterinary e-CPD: a new model for providing online continuing professional development for the veterinary profession.

Continuing professional development (CPD) is widely recognized as an important element in effective lifelong learning for veterinary surgeons. Traditional methods of CPD do not suit all learners, as issues such as location, time, cost, and structure sometimes prevent individuals from completing the required number of CPD study hours per year. The rapid development of the Internet, and with it the increasing scope and sophistication of e-learning, provides new opportunities to address some of these constraints on the provision of CPD.

Sinonasal plasmacytoma in a cat.

A 13-year-old female spayed Domestic Shorthair cat presented with a history of right-sided mucopurulent nasal discharge for 18 months. Computed tomography revealed a mass within the right nasal cavity and the right frontal sinus. The animal was euthanized, and a postmortem examination was performed.

Assessment of the Effect of an Aliamide-containing Topical Gel by Evaluation of the Reduction of Wound Volume Measured by High R.

This study evaluated the use of an aliamide-containing gel in the treatment of skin wounds by employing noninvasive wound volume measurements acquired from wound images of high resolution ultrasonography (HRU). The dorsal thoracolumbar areas of 10 Beagle dogs were clipped and 2 rows of 6 full-thickness 5-mm punch biopsy samples were taken from either side of the midline under general anaesthesia. Wounds were allowed to heal by secondary intention, while treatment gel or base was applied 3 times daily to randomly selected treatment and control groups.

Utility of magnetic resonance imaging for distinguishing neoplastic from non-neoplastic brain lesions in dogs and cats.

The aim of this study was to identify magnetic resonance (MR) signs that aid differentiation of neoplastic vs. non-neoplastic brain diseases in dogs and cats. MR images of 36 dogs and 13 cats with histologic diagnosis of intracranial disease were reviewed retrospectively.

Changes in ultrasonographic appearance of adrenal glands in dogs with pituitary-dependent hyperadrenocorticism treated with trilostane.

Trilostane, a 3beta-hydroxysteroid dehydrogenase inhibitor, has been used successfully over the last few years for the treatment of canine pituitary-dependent hyperadrenocorticism. In a prospective study of 19 dogs with pituitary-dependent hyperadrenocorticism, the adrenal glands were measured before and at least 6 months after initiation of trilostane therapy. Right adrenal gland length and caudal pole thickness and left adrenal gland caudal pole thickness increased significantly (p < or = 0.

Balloon dilatation of nasopharyngeal stenosis in a cat.

A cat was diagnosed with nasopharyngeal stenosis on the basis of clinical signs, survey and contrast radiography, endoscopy and magnetic resonance imaging. The condition was successfully managed with repeated balloon dilatation.
