Abdominal ultrasound examinations (AUEs) are commonly used in the diagnostic evaluation of canine acute pancreatitis (AP). The purpose of this retrospective study was to evaluate and monitor the ultrasonographic changes observed in dogs with clinically suspected AP on consecutive AUEs. The study population was constituted by 38 client-owned dogs hospitalized for no less than 48 h from January 2016 to December 2019. Dogs included in this study were suspected of AP based on the clinical examination and abnormal rapid specific canine pancreatic lipase test performed at admission. Dogs were submitted to two AUEs, the first on the first day of hospitalization, and the second between 40–52 h after the first one. Twelve dogs had both AUEs suggestive of AP. Fourteen dogs received an ultrasonographic diagnosis of AP exclusively on the second AUE. Twelve dogs remained negative on both the first and the second AUE. In 26 out of 38 patients the second AUE was suggestive of AP. If a patient is suspected of AP, it is advisable to carry out ultrasonographic monitoring at least within the first 52 h after admission, since ultrasonographic signs of AP may only become observable later after hospitalization.

Given the abundance of chickens in Italy, it is important for veterinarians to know the normal state of chickens’ eyes in order to identify any ophthalmic pathological changes. The aim of this study was to determine the normal values of select ocular parameters and to evaluate conjunctival microflora in two Italian chicken breeds. Sixty-six healthy chickens underwent a complete ophthalmic examination, which included a phenol red thread test (PRTT) for the evaluation of tear production and the assessment of intraocular pressure by rebound tonometry. B-mode ultrasound biometric measurements and conjunctival microflora identification were also performed in twenty-seven chickens. Mean PRTT was 23.77 ± 2.99 mm/15 s in the Livorno breed and 19.95 ± 2.81 mm/15 s in the Siciliana breed. Mean intraocular pressure was 14.3 ± 1.17 mmHg in the Livorno breed and 14.06 ± 1.15 mmHg in the Siciliana breed. Reference ranges for morphometric parameters were reported in the two breeds. Twenty-three chickens (85.18%) were bacteriologically positive. Chlamydia spp. antigen was detected in 14.81% of chickens. No positive cultures were obtained for fungi. Normal reference range values for selected ophthalmic parameters were obtained in clinically healthy chickens, which could facilitate accurate diagnosis and better management of ophthalmic diseases in these animals.

Background: The evidence of mineralizations in the canine liver is usually considered an incidental finding of unclear clinical significance, frequently observed in small size old dogs. Aim: To describe the ultrasound features of intrahepatic biliary tree foci of mineralization, to assess their clinical relevance and their possible relationship with other gastrointestinal pathological disorders. Methods: A retrospective analysis evaluating the database of canine patients admitted to two referral veterinary centers we carried out. All dogs under study underwent an abdominal ultrasound examination in which intrahepatic biliary tree mineralization was found. Clinical and anamnestic data of the included dogs were reviewed. Results: Approximatively 90% of the patients showed ultrasonographic abnormalities regarding the biliary system, and over 85% presented ultrasonographic abnormalities of the hepatic parenchyma. In 81.2% of dogs, ultrasonographic anomalies in the digestive tract were observed. In approximately the half of our patients, we evidenced increased liver enzymes (ALP, ALT and GGT). At clinical evaluation, 84.4% (23 out of 32 dogs) of patients showed signs of gastrointestinal disease that persisted for over three months. Conclusion: The presence of intrahepatic biliary tree mineralizations is an unusual and frequently incidental finding that could be related to a bile stasis condition, a chronic inflammatory disease involving the biliary system and the hepatic parenchyma, and it could be associated to a liver-gut axis alteration.
