Despite the existence of the American College of Veterinary Pathology guidelines for tumour biopsy specimens, anecdotally the authors' have seen inconsistency of reporting of information on the pathology report for canine soft tissue sarcomas (STSs). If crucial aspects are not reported this can result in slower or impeded patient care. This retrospective study evaluated 255 STS histopathology reports submitted from across the United States. Reports were evaluated by a single observer to assess for information contained in 5 main categories: patient history and signalment, gross and microscopic description, grading, histologic margins and the comments section...

Intestinal T-cell lymphoma is being more frequently diagnosed in dogs owing to the wide availability of endoscopy and clonality analysis in veterinary medicine. However, no epidemiological study on intestinal T-cell lymphoma has been previously performed, and hence, information about dog breed, age and sex distributions of intestinal T-cell lymphoma has largely remained unclear. In this study, breed predisposition to canine intestinal T-cell lymphoma was determined by calculating odds ratios and 95% confidential intervals...

BACKGROUND: Clinical pathology investigations are essential to evaluate the health status and practice management of ruminants. Appropriate and accurate RIs are required for the interpretation of laboratory results. Despite substantial phenotypic differences and management-related disparities between male and female sheep, RIs in rams are sparse and limited by small reference populations and outdated methods. OBJECTIVES: The purpose of this study was to establish RIs for hematologic, biochemical, and hormonal analytes in adult rams using controlled preanalytic and analytic procedures, and to investigate whether breed-dependent partitioning of RIs is required...

Culling, vaccinating, and monitoring animals are the three main techniques used in contemporary veterinary public health to manage animal diseases that can be transmitted to humans. Each technique is underpinned by different ontological understandings of how microbes figure in relations between humans and animals. Therefore, animal diseases are not only a question for an applied anthropology but also involve the theoretical core of the discipline i.e., understanding how social causality emerges out of physical causality...

Case summary: Mammary fibroadenomatous hyperplasia (MFH) is a benign pathology characterised by extensive proliferation of the ductal epithelium and mammary stroma. It typically occurs in young female cats, and seems to result from hypersensitivity to progesterone. A 2-year-old entire male European Shorthair cat presented to the veterinary clinic with enlargement of several mammary glands, which had developed within the previous 10 days. There was no prior administration of progestin in the cat's medical history...

Veterinary parasitology has always been considered to be relevant and interesting by the Danish veterinary students. Students have to acquaint themselves with many new, small creatures with complicated and varied life cycles and with intricate Latin names that are difficult to pronounce, as only a few parasites have Danish names. In our veterinary curriculum, zoology has disappeared as a discipline, and parasitology has gradually moved from the third year to the beginning of the second year, which implies that, for example, pathology and pharmacology are "unknown fields"...

BACKGROUND: Renal disease is considered the main cause of natural mortality in dogs with canine leishmaniosis. The pathological mechanisms associated with kidney injury in canine leishmaniosis include immune complex glomerulonephritis, tubulointerstitial nephritis and occasionally renal amyloidosis. Proteinuria is a frequent finding in canine leishmaniosis and its quantification by the urine protein-creatinine ratio (UPC) is an important parameter in the staging of canine lesihmaniosis as presented by the LeishVet group...

Eosinophils within the central nervous system are abnormal and are usually associated with fungal or parasitic infections in horses. Causative agents include Halicephalobus gingivalis, Sarcocystis neurona, and Neospora hughesi. Confirmation of these organisms via specific testing is typically not performed, and final diagnoses are often presumptive. With molecular technology, many of these organisms can now be confirmed. This is important for emerging and zoonotic pathogens, including Angiostrongylus cantonensis, an emerging parasite of interest in the southeastern United States...

Meniscal pathologies are among the most common injuries of the femorotibial joint in both human and equine patients. Pathological forces and ensuing injuries of the cranial horn of the equine medial meniscus are considered analogous to those observed in the human posterior medial horn. Biomechanical properties of human menisci are site- and depth- specific. However, the influence of equine meniscus topography and composition on its biomechanical properties is yet unknown. A better understanding of equine meniscus composition and biomechanics could advance not only veterinary therapies for meniscus degeneration or injuries, but also further substantiate the horse as suitable translational animal model for (human) meniscus tissue engineering...

Between June and November 2015, 25 woodpeckers (Picidae) with neurologic signs or unknown cause of death were admitted to a veterinary clinic. Alive birds were clinically examined. Birds that were found dead or died despite intensive care treatment were forwarded to a pathologic examination. Necropsy and subsequent tests included screening for several infectious agents and toxins. Three birds tested positive for Sarcocystis calchasi. Toxoplasma gondii was detected in one bird demonstrating intracerebral cysts...

BACKGROUND: The Arabian Sand Gazelle (Gazella subgutturosa marica, Thomas, 1897) has been extirpated throughout the Arabian Peninsula. Captive breeding and reintroduction for conservation purposes require veterinary support and the use of hematology RIs. OBJECTIVES: The purpose of the study was to establish hematological RIs for the Arabian Sand Gazelle. METHODS: Blood from 231 clinically healthy captive and 22 wild (reintroduced) Arabian Sand Gazelles were sampled...

BACKGROUND: Empty sella is the neuroradiological or pathological finding of an apparently empty sella turcica containing no pituitary tissue. The prevalence of primary empty sella, i.e., empty sella without any discernible cause, is not precisely known; estimates range from 2% to 20%. Technical advances in neuroradiology have made empty sella an increasingly common incidental finding. It remains unclear whether, and to what extent, asymptomatic adult patients with an incidentally discovered empty sella should undergo diagnostic testing for hormonal disturbances...

Clinical pathology testing of rodents is often challenging due to insufficient sample volume. One solution in clinical veterinary and exploratory research environments is dilution of samples prior to analysis. However, published information on the impact of preanalytical sample dilution on rodent biochemical data is incomplete. The objective of this study was to evaluate the effects of preanalytical sample dilution on biochemical analysis of mouse and rat serum samples utilizing the Siemens Dimension Xpand Plus...

While articular cartilage changes are considered to be one of the initial events in the pathological cascade leading to osteoarthritis, these changes remain difficult to detect using conventional diagnostic imaging modalities such as plain radiography. The aim of this prospective, experimental, methods comparison study was to compare the sensitivity of magnetic resonance imaging (MRI), magnetic resonance arthrography, computed tomography (CT), and CT arthrography in the detection of artificially induced articular cartilage defects in the equine carpal joints...

OBJECTIVES: Laryngomalacia is the most common cause of stridor in infants. Dynamic airway collapse is also a well-recognised entity in horses and an important cause of surgical veterinary intervention. We compare the aetiology, clinical features and management of human laryngomalacia with equine dynamic airway collapse. METHODS: A structured review of the PubMed, the Ovid Medline and the Cochrane Collaboration databases (Cochrane Central Register of Controlled Trials, Cochrane Database of Systemic Reviews)...

Filarial nematodes of the Eulimdana genus inhabit subcutaneous tissue of various avian species, mostly Charadriiforme birds. In domestic pigeons, E. clava is the only species recorded in the subcutaneous tissue in a number of isolated cases. In the present study, we discuss the morphology and histopathology of filarial nematodes recovered from subcutaneous tissue of domestic pigeons in Bosnia and Herzegovina. In total 110 pigeons were submitted to necropsy at the Department of Pathology of the Faculty of Veterinary Medicine in Sarajevo...

Peter J Dickinson, Sarah Jones-Woods, Derek D Cissell
Postcontrast, fluid-attenuated inversion recovery (FLAIR) sequences are reported to be of variable value in veterinary and human neuroimaging. The source of hyperintensity in postcontrast-T2 FLAIR images is inconsistently reported and has implications for the significance of imaging findings. We hypothesized that the main source of increased signal intensity in postcontrast-T2 FLAIR images would be due to gadolinium leakage into adjacent fluid, and that the resulting gadolinium-induced T1 shortening causes reappearance of fluid hyperintensity, previously nulled on precontrast FLAIR images...
