Retrospective Look at Septic Subtendinous Calcaneal Bursitis inside 30 Cow.
Xanthogranuloma of the sellar region has been reported in both humans and animals. The lesion is rare, and its aetiology and pathogenesis are not fully understood. The association of sellar xanthogranuloma with an adenoma, known as xanthogranulomatous pituitary adenoma (XPA), is an extremely rare condition in humans and is usually associated with anterior pituitary insufficiencies, headache, vomiting and visual deficits. We present the first report of XPA in an animal. A 7-year-old male neutered Labrador Retriever was presented for investigation of progressive lethargy, vomiting and hyporexia, having been previously diagnosed with chronic kidney disease, pituitary-dependent hyperadrenocorticism and hypoparathyroidism. The dog was euthanized due to lack of response to medical treatment and post-mortem examination revealed XPA. Although rare, xanthogranulomatous lesions should be considered in patients with pituitary disease.Uraemia is a clinical syndrome caused by an increase in uraemia-associated toxins in the bloodstream as a consequence of intrinsic kidney or lower urinary tract diseases. Cats seem to be more affected by urinary tract diseases than dogs, particularly considering that chronic kidney disease (CKD) is one of the most important conditions in cats. Considering the lack of information on the systemic lesions of uraemia in cats, the aim of this study was to investigate the prevalence and clinical and pathological aspects of non-renal lesions in uraemic cats, with special attention to the differences between cats and dogs. Cats necropsied between 2000 and 2019 (n = 1,330) were investigated for urinary tract diseases and non-renal lesions of uraemia. The prevalence of uraemic cats with non-renal lesions (n = 78) was 5.8%. Adult, elderly and male animals were predominantly affected. Anorexia, apathy and vomiting were the most common clinical signs and CKD was observed in the majority of uraemic cats. Pulmonary oedema was the most frequent non-renal lesion identified. In contrast with previous reports, haemorrhagic and ulcerative gastritis was frequently observed, whereas soft tissue mineralization and parathyroid hyperplasia were uncommon features. Fibrous osteodystrophy was not observed. Cats with urinary tract diseases did not have as wide a variety of non-renal uraemic lesions as uraemic dogs and multisystemic manifestation of uraemia was observed in only 24.4% of cases.Uraemic encephalopathy (UE) is rarely associated with acute kidney injury or chronic kidney disease in domestic animals, and we now report the first case in a cat. The animal presented with hypothermia, apathy, lethargy, depression, severe dehydration, uraemic breath, elevated serum urea nitrogen and creatine concentrations, and eventual seizures and coma prior to death. Gross necropsy findings included severe bilateral renal scarring, ulcerative stomatitis and glossitis, and uraemic gastropathy. Microscopic lesions of diffuse interstitial fibrosis, multifocal mineralization and lymphoplasmacytic interstitial nephritis were seen in the kidneys. There was symmetrical, bilateral spongy vacuolation of the white matter of the basal nuclei and cerebellum and Alzheimer type II astrocytes in the cerebral cortex and hippocampus. Glial fibrillary acid protein immunolabelling was absent or faint in astrocytes of the cerebral grey matter. UE should be included in the differential diagnosis in animals with chronic kidney disease and neurological signs.Myofibromas are mesenchymal tumours of myofibroblastic origin that occur in solitary or multicentric forms. Solitary benign myofibromas mainly occur on the head and neck, especially in the subcutaneous region. They rarely occur in visceral organs in humans, but visceral myofibroma has not been reported in animals. We now report a case of testicular myofibroma in a 6-year-old rabbit in which orchiectomy revealed an enlarged testis with a multinodular surface. The cut surface of the testis showed a thick, homogeneous white-yellow mass surrounding the testicular parenchyma. Histopathologically, the mass was composed of collagen and eosinophilic fascicles of spindle cells that were immunopositive for α-smooth muscle actin but not desmin, S-100 or von Willebrand factor. These features distinguished the myofibroma from other spindle cell tumours. To the best of our knowledge, this is the first report of solitary testicular myofibroma in any animal species.The objective of this study was to determine communication preferences of dairy producers in Canada. A secondary objective was to evaluate social media engagement of dairy producers. A survey was administered to Canadian dairy producers between March and April, 2015 to collect information on current management practices on their farms. A total of 1,373 Canadian dairy producers responded to the survey, representing a response rate of 12%. selleckchem The survey consisted of 192 questions; however, only questions regarding producer demographics, importance of information sources, and internet and social media use were evaluated in this study. The primary outcome variables of interest included use of the internet to access dairy information, importance of different sources of information about dairy herd health and management, and use of online search engines and social media platforms. For each outcome, logistic regression analyses were used to investigate associations between the outcome and demographic variables.

We hypothesized that insulin potentiates essential AA stimulation of mTORC1 activity in the MAC-T mammary epithelial cell line. Here, our objective was to assess mTORC1 signaling activity in response to insulin and individual or grouped essential AA. Insulin and essential AA concentrations in the treatment medium ranged from normo- to supraphysiological, with insulin at 0, 1, 10, or 100 nmol/L and essential AA at approximately 0, 0.01, 0.05, 0.1, 1, or 3× reference plasma levels. Effects and interaction of insulin and total essential AA were tested in a 3 × 5 factorial design (n = 3 replicates/treatment); insulin and the individual AA Leu, Met, Ile, and Arg were likewise tested in 3 × 4 factorials (n = 4). As the remaining individual AA His, Lys, Phe, Thr, Trp, and Val were expected to not affect mTORC1, these were tested only at the highest insulin level, 100 nmol/L (n = 4).
