A 5-year-old intact female Persian cat was referred with anorexia and vomiting. Physical examination revealed icterus in the pinna, oral mucosa, and sclera. Ultrasonography revealed several findings including uniformly hyperechoic hepatic parenchyma compared to adjacent falciform fat, increased attenuation of the ultrasound beam, and poor visualization of intrahepatic vessel borders. Computed tomography revealed hypoattenuation of the hepatic parenchyma with a radiodensity value of-60 Hounsfield units. The adjacent intrahepatic vessels appeared hyperattenuated relative to the hepatic parenchyma as if the vessels were contrast-enhanced. Based on ultrasonography and computed tomography results, the cat was tentatively diagnosed as feline hepatic lipidosis.

A 6-year-old female domestic short hair cat presented with acute onset of vomiting, anorexia, lethargy, and tachypnea. The cat was apparently healthy prior to presentation without history of trauma. On diagnostic imagings, the entire stomach and spleen were detected in the thoracic cavity. An emergent celiotomy was performed, and a type4 hiatal hernia was confirmed; the stomach, spleen, pancreas, and duodenum were herniated through the esophageal hiatus. It was corrected using phrenicoplasty, esophagopexy, and left-sided gastropexy and there was no recurrence 16 months after surgery. This is the first case report of an idiopathic type-4 hiatal hernia in a cat.

Hwang, T., Gyeongsang National University, Jinju, Republic of Korea | Park, J., Gyeongsang National University, Jinju, Republic of Korea | Jung, D., Gyeongsang National University, Jinju, Republic of Korea | Lee, H.C., Gyeongsang National University, Jinju, Republic of Korea
An 11-year-old, castrated male dog presented with a 3-month history of cough and depression. Auscultation revealed systolic murmur and thoracic radiographs showing enlargement of both the atrium and left ventricle. Echocardiography showed thickened mitral valve and moderate-to-severe left atrial enlargement. Additionally, M-mode echocardiography showed symmetric left ventricular wall thickening and systolic anterior motion of the mitral valve, while Doppler imaging revealed high velocity turbulent flow through the left ventricular outflow tract. Based on echocardiography, this case was diagnosed with hypertrophic obstructive cardiomyopathy. After 5 months, the dog was clinically static in radiography and echocardiography.

The pathogenesis of pancreatic pseudocyst is still not understood. A 5-year-old, 24-kg intact female Shetland Sheepdog was presented with anorexia and vomiting. Diagnostic imaging tests revealed that the left limb of the pancreas was thickened and contained two cystic lesions (6.3 x 5.6 x 4 cm³ and 3.5 x 4.6 x 5.5 cm³ ). During the laparotomy, lesions were opened with de-roofing of superabundant tissue, and omentalization was performed. The dog recovered uneventfully after surgery and was discharged on postoperative day 12. Histopathologically, it was diagnosed as chronic pancreatic pseudocyst. This case report describes the diagnosis and successful omentalization of pancreatic pseudocysts in a dog.

Kim, J.H., Animal and Plant Quarantine Agency, Gimcheon, Republic of Korea | Lee, K., Animal and Plant Quarantine Agency, Gimcheon, Republic of Korea | Jung, J.Y., Animal and Plant Quarantine Agency, Gimcheon, Republic of Korea | Yi, H., Animal and Plant Quarantine Agency, Gimcheon, Republic of Korea | Sohn, J.H., Gyeongbuk Veterinary Service Laboratory, Andong, Republic of Korea | So, B.J., Animal and Plant Quarantine Agency, Gimcheon, Republic of Korea | Choi, E.J., Animal and Plant Quarantine Agency, Gimcheon, Republic of Korea
Two 12-month-old cattle with anthelmintics containing trichlorfon the day before death presented to the Animal and Plant Quarantine Agency for diagnosis. In necropsy, they revealed enlargement of the spleens, redness of mucosa and serosa in stomachs and intestines, and friable kidneys. Histopathologically, hemorrhages in the spleens, omasums, abomasums, and intestines as well as renal tubular necrosis were observed. Trichlorfon was detected at above the lethal dose in the ruminal contents. Based on these findings, we diagnosed this case as death caused by trichlorfon poisoning.

2018
Lee, S.J., Gyeongsang National University, Jinju, Republic of Korea | Cho, G.H., Gyeongsang National University, Jinju, Republic of Korea | Kim, M.K., Gyeongsang National University, Jinju, Republic of Korea | Kim, C.S., Gyeongsang National University, Jinju, Republic of Korea | Won, C.K., Gyeongsang National University, Jinju, Republic of Korea
The aim of this study was to investigate morphological development of filiform papillae (FP) in Korean native goats by using scanning electron microscopy. Tongues were removed from goat fetuses (days 60, 90, and 120), neonates, and juveniles (days 30, 60, 90, 120, 150, and 180 after birth). During the prenatal period, primordia of FP appeared at fetal day 60 and were observed to be developed at day 90. At fetal day 120, the FP were observed like flower leaves of a double flower bud. In neonates, FP were shaped like an obliquely sectioned cylinder with secondary papillae irregularly arranged in a saw blade-like manner. In 60-day-old juvenile goats, the FP were densely distributed at the inner base of 1/3-1/2 degrees. In 90-, 120-, and 150-day-old goats, FP were compacted at the inner base of 1/2-2/3, 3/4, and 4/5 degrees, respectively. In 180-day-old goats, FP were found to be completely compacted on the inner surface with complete morphogenesis. Microridges, microplicae, and micropits were well-developed on the epithelial surface of lingual papillae from embryonic day 120 to juvenile day 180. These results indicate that FP of goats have different shapes and sizes during development both before and after birth.

2018
Park, Y., Seoul National University, Seoul, Republic of Korea | Kang, S., Seoul National University, Seoul, Republic of Korea | Jeong, M., I Animal Medical Center, Bucheon, Republic of Korea | Park, J., Olive Animal Hospital, Seoul, Republic of Korea | Seo, K., Seoul National University, Seoul, Republic of Korea
A 13-year-old neutered male Poodle dog was presented with a third eyelid mass in the left eye. The dog had undergone local resection of the mass about a year prior in a private practice. On cytological examination, the mass was diagnosed as adenocarcinoma. Although lung and lymph node metastases were suspected, based upon the computed tomographic results, exenteration was performed to relieve chronic pain and to improve the dog’s quality of life. Exenteration carried a good prognosis with no tumor recurrence until 1 year and 10 months after surgery, when local recurrence occurred near the left zygomatic arch.

OBJECTIVE To assess and compare 2 injection techniques for conducting ocular anterior segment indocyanine green angiography (ASICGA) and sodium fluorescein (SF) angiography in horses. ANIMALS 3 healthy adult female horses (age range, 19 to 25 years). PROCEDURES Horses were sedated, jugular catheters were placed, and manual restraint was used to ensure proper positioning for the angiography procedure. Two injection techniques (IV and intra-arterial) were performed for each horse 1 week apart. Intravenous injections of 0.25% indocyanine green (ICG; 50 mg) and 10% SF (10 mg/kg) were administered via the jugular catheter. Intra-arterial injections of ICG (1 mg) and SF (1 mg/kg) were administered into the common carotid artery with ultrasound guidance. Angiography was performed by use of an adaptor system comprised of a modified digital single-lens reflex camera, camera adaptor, and lens. Imaging was performed at a rate of 3 images/s for 60 seconds immediately following ICG injection, then at 2, 3, 4, and 5 minutes after injection. The SF was injected 5 minutes thereafter. RESULTS ASICGA allowed visual identification of the arterial, capillary, and venous phases of angiography. Intra-arterial administration provided superior dye fluorescence, sharper contrast, and faster dye passage than IV administration. Visibility of the iris vasculature was limited with SF, and extravasation of SF was noted. No clinically important adverse events were detected. CONCLUSIONS AND CLINICAL RELEVANCE ASICGA images were obtainable with both injection techniques; however, visibility of the iris vasculature was better with intra-arterial administration of ICG. The ASICGA technique may serve as a viable ocular imaging modality for horses.

OBJECTIVE To evaluate the diagnostic yield of dental radiography (Rad method) and 3 cone-beam CT (CBCT) methods for the identification of predefined anatomic landmarks in brachycephalic dogs. ANIMALS 19 client-owned brachycephalic dogs admitted for evaluation and treatment of dental disease. PROCEDURES 26 predefined anatomic landmarks were evaluated separately by use of the RAD method and 3 CBCT software modules (serial CBCT slices and custom cross sections, tridimensional rendering, and reconstructed panoramic views). A semiquantitative scoring system was used, and mean scores were calculated for each anatomic landmark and imaging method. The Friedman test was used to evaluate values for significant differences in diagnostic yield. For values that were significant, the Wilcoxon signed rank test was used with the Bonferroni-Holm multiple comparison adjustment to determine significant differences among each of the 6 possible pairs of diagnostic methods. RESULTS Differences of diagnostic yield among the Rad and 3 CBCT methods were significant for 19 of 26 anatomic landmarks. For these landmarks, Rad scores were significantly higher than scores for reconstructed panoramic views for 4 of 19 anatomic landmarks, but Rad scores were significantly lower than scores for reconstructed panoramic views for 8 anatomic landmarks, tridimensional rendering for 18 anatomic landmarks, and serial CBCT slices and custom cross sections for all 19 anatomic landmarks. CONCLUSIONS AND CLINICAL RELEVANCE CBCT methods were better suited than dental radiography for the identification of anatomic landmarks in brachycephalic dogs. Results of this study can serve as a basis for CBCT evaluation of dental disorders in brachycephalic dogs.
Mostrar más [+] Menos [-]Salmonella fecal shedding in pigs from birth to market and its association with the presence of Salmonella in palatine tonsils and submandibular lymph nodes at slaughter

Salmonella is an important cause of foodborne illnesses in humans. Food-producing animals, including swine, are a major source of Salmonella in food products. This study investigated on farm Salmonella fecal shedding in pigs at different production stages - from weaning to marketing - and its association with the presence of Salmonella in tissues at slaughter. Fourteen groups from 8 commercial farrowing sources (N = 809 pigs) were monitored 5 times from birth to slaughter. Fecal and tissue samples were collected from pigs and cultured for Salmonella. A survey was conducted to collect farm management information. A multi-level mixed-effects logistic regression modelling method was used to analyze Salmonella shedding over time and the association between Salmonella shedding and the presence of Salmonella in tissue samples. Salmonella was recovered from 13% (421/3339) of fecal samples collected from 809 pigs over the course of the study. Overall, 35% (284) of pigs shed Salmonella at least once, while 12% (99) shed more than once. Salmonella shedding increased as pigs aged (P = 0.01) and increased in the summer months (P < 0.01). Salmonella was isolated from tissue samples collected from 23% (134/580) of pigs; however, the presence of Salmonella at slaughter was not associated with on farm shedding. The seasonal trend in Salmonella shedding and its association with age may be used to identify high-risk groups and implement more effective control measures accordingly. The identification of repeat shedders warrants interventions that target this source of infection on swine farms.
