Computed tomography reports of 311 rabbits taken for any reason over a 4-year period were evaluated for recorded evidence of appendicular osteoarthritis and the joint(s) affected. Risk factors including age, weight, body condition, breed, sex and neuter status were investigated. In rabbits with evidence of osteoarthritis, clinical notes were examined to evaluate if the condition was clinically apparent. Out of 311 computed tomography reports, 61 described evidence of osteoarthritis (19.6%). The most common joints affected were the elbow and stifle. No significant relationship between sex, body condition and neuter status in males and presence of osteoarthritis was found. A statistically significant relationship between greater age, greater weight and neuter status in females and the presence of osteoarthritis was found. Only 9 out of 61 (14.8%) of the rabbits with computed tomography evidence of osteoarthritis had clinical signs of osteoarthritis recorded in the clinical notes. Following the results of this study, it may be concluded that greater age and weight, as well as female neuter status, are related to increased risk of appendicular osteoarthritis in rabbits, but changes on imaging may relate poorly to clinically apparent disease.","PeriodicalId":10606,"journal":{"name":"Companion Animal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139683518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The owner reported a single tonic-clonic seizure 7 months before presentation and intermittent mild gastrointestinal signs for the past 18 months. Initial investigations revealed hyponatraemia, hyperkalaemia and increased levels of liver enzymes. An adrenocorticotropic hormone stimulation test excluded hypocortisolism. The gastrointestinal signs resolved following a dietary change, suggesting that chronic enteropathy and most primary and secondary causes of hepatic disease were excluded, leaving idiopathic chronic hepatitis as the most likely cause of increased levels of liver enzymes. Liver parameters reduced to levels just above reference range after immunosuppressive doses of prednisolone. Aldosterone levels pre- and post-adrenocorticotrophic hormone stimulation were <20 pmol/litre, consistent with mineralocorticoid deficiency. The mineralocorticoid deficiency was treated with desoxycorticosterone pivalate at 1–1.3 mg/kg subcutaneously every 48–87 days, which resulted in immediate and complete resolution of the clinical signs and electrolyte imbalance. Given the dog's signalment and results from clinical investigations, the isolated hypoaldosteronism is speculated to be caused by immune-mediated adrenal gland destruction. Isolated hypoaldosteronism should be considered a differential diagnosis for hyponatraemia in dogs, when an adrenocorticotrophic hormone stimulation test excludes hypocortisolism.","PeriodicalId":10606,"journal":{"name":"Companion Animal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139810112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Galac","doi":"10.12968/coan.2023.0036","DOIUrl":"https://doi.org/10.12968/coan.2023.0036","url":null,"abstract":"Phaeochromocytomas are neuroendocrine tumours arising from chromaffin cells of the adrenal medulla. Clinical signs are primarily associated with excessive catecholamine secretion and, to a lesser extent, with the space-occupying or invasive nature of the tumour. The diagnosis of phaeochromocytoma relies on clinical suspicion, biochemical testing, diagnostic imaging and histopathology. Biochemical testing mainly depends on the measurement of levels of plasma or urinary metanephrines, with normetanephrine demonstrating superior diagnostic performance compared to metanephrine. Adrenalectomy is the treatment of choice, but may not be possible in cases with extensive local invasion, concurrent disorders or distant metastasis. Contrast-enhanced computed tomography is recommended for surgical planning and metastasis screening. Vascular invasion is frequently observed, yet surgery remains a viable option in many cases. Recent studies question the necessity of alpha-blockade before surgery, and randomised controlled clinical trials are necessary to evaluate this. Long-term survival is often seen in dogs that survive the perioperative period. For patients in which surgery is not deemed feasible, medical treatment with tyrosine-kinase inhibitors may be considered. Given the current scarcity of effective medical treatment, there is an urgent need to identify novel therapeutic options. This review provides recommendations on the diagnosis and management of canine phaeochromocytoma.","PeriodicalId":10606,"journal":{"name":"Companion Animal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139453097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
