Automated Assessment of Pelvic Longitudinal Rotation Using Computer Vision in Canine Hip Dysplasia Screening.

Canine hip dysplasia (CHD) screening relies on accurate positioning in the ventrodorsal hip extended (VDHE) view, as even mild pelvic rotation can affect CHD scoring and impact breeding decisions. This study aimed to assess the association between pelvic rotation and asymmetry in obturator foramina areas (AOFAs) and to develop a computer vision model for automated AOFA measurement. In the first part, 203 radiographs were analyzed to examine the relationship between pelvic rotation, assessed through asymmetry in iliac wing and obturator foramina widths (AOFWs), and AOFAs.

Prognostic Factors in 26 Cats Undergoing Surgery for Extra-Hepatic Biliary Obstruction.

Surgical management of feline extra-hepatic biliary obstruction (EHBO) has poor survival rates with few prognostic factors reported in the literature. The etiology and clinical findings of feline EHBO and their influence on short-(2 weeks-6 months) and long-term (>6 months) survival and prognosis were examined in an observational clinical retrospective study of 26 client-owned cats undergoing surgery for biliary obstruction at one institution between 2012 and 2020. The etiology of EHBO was determined in 21/26 cats, which included inflammatory causes (14/21), neoplastic causes (6/21), and a duodenal foreign body (1/21).

Management of an Acquired Palatal Defect With a 3-Dimensional Printed Palatal Obturator in a Dog.

Large defects in the hard palate can be difficult to treat surgically, as dehiscence is common. These defects may instead be managed with a palatal obturator, which can serve to separate the oral and nasal cavities. In this report, a 7-year-old, mixed breed dog was treated with a palatal obturator, after presenting with an acquired palatal defect following treatment of a giant cell tumor of bone in the hard palate.

Ferret Gastroenterology.

Ferrets (Mustela putorius furo) commonly present with gastrointestinal disease, which can be of noninfectious and infectious origin. Clinical signs are often nonspecific, and can include lethargy, anorexia, vomiting, diarrhea, and melena. Obtaining a detailed history, followed by a thorough physical examination and systematic diagnostic approach are the key to obtaining a correct diagnosis.

Profiling host- and parasite-derived miRNAs associated with Strongylus vulgaris infection in horses.

The equine bloodworm, Strongylus vulgaris, is a common and highly pathogenic parasite in horses due to its migratory life cycle involving the intestinal arteries. Current diagnostic techniques cannot detect the prepatent migrating stages of S. vulgaris, highlighting the need for new biomarkers.

Observer reliability in counting erythrocyte ghost cells and impact of short-term storage of canine and feline blood samples.

The presence of erythrocyte ghost cells (EG) in blood smears indicates intravascular haemolysis or in-vitro haemolysis. However, observer reliability in detection of EG has not been documented. Immediate blood smear preparation is advised but may not always be practical.

Vancomycin-resistant Staphylococcus aureus endangers Egyptian dairy herds.

The emergence of pandrug-resistant (PDR) and extensive drug-resistant (XDR) methicillin-resistant and vancomycin-resistant Staphylococcus aureus (MRSA and VRSA) isolates from bovine milk samples along with biofilm formation ability and harboring various virulence genes complicates the treatment of bovine mastitis and highlights the serious threat to public health. This study investigated for the first time the frequency, antimicrobial resistance profiles, biofilm-forming ability, virulence factors, spa and staphylococcal cassette chromosome mec (SCCmec) types of MRSA and VRSA isolated from clinical and subclinical bovine mastitis in Egypt. A total of 808 milk samples were collected from each quarter of 202 dairy animals, including 31 buffaloes and 171 cattle.

ORAL MICROBIOME OF BENNETT'S () AND YELLOW-FOOTED () ROCK WALLABIES AND THE IMPACT OF INTRAORAL DISEASE.

Intraoral disease, including macropod progressive periodontal disease, is one of the leading causes of morbidity and mortality for wallabies under human care. Clinical signs associated with intraoral disease vary, and diagnostic findings can be difficult to interpret without intraoral radiographs or advanced imaging; therefore, this disease process can be challenging to detect in its early stages. Previous studies have investigated the effects of intraoral disease on the normal oral microbiome of various domestic species.

Variability in performance of agility dogs navigating a dynamic obstacle.

Introduction: During agility performance, dogs complete a preset obstacle course. The teeter, also known as the seesaw, is the only dynamic contact obstacle. Dogs handle dynamic obstacles differently than static obstacles due to the need for increased coordination and postural control.

Chlorambucil is used in veterinary medicine for various cancers, while Toceranib, which was licenced for treating canine mast cell tumours, is now used against other solid tumours. Both drugs are generally safe, but their combined use has not been studied. This study aimed to investigate retrospectively the safety profile of the Chlorambucil-Toceranib combination against canine solid tumours.

Hepatic parenchymal hypoattenuation in dogs with diabetes mellitus on computed tomography consistent with hepatic steatosis.

Hypoattenuation of the liver, consistent with hepatic steatosis or lipidosis, has been reported in veterinary patients. In people, measuring CT hepatic attenuation is diagnostic for hepatic steatosis, and hypoattenuation of the liver is defined as absolute if less than 40 HU or relative if the liver is 10 HU less than the spleen. The purpose of this study is to describe hepatic parenchymal attenuation in dogs with diabetes mellitus with or without diabetic ketosis (DK) or diabetic ketoacidosis (DKA), using the above categorization for absolute and relative hypoattenuation, as with humans.
