Abstract : A dog was presented with a cough, dyspnea, nasal discharge, gagging, and exercise intolerance. The dog showed leukocytosis, peripheral eosinophilia, and an increase C-reactive protein. The radiographic findings noted bronchointerstitial infiltration, intrathoracic lymphadenopathy, and soft tissue opacity mass. Computed tomography findings showed thickening of the bronchus and bronchiole. Also, peri-bronchial consolidation and generalized intrathoracic lymphadenopathy was present. On blind bronchoalveolar lavage and pulmonary cytology, there were significantly increased eosinophils. Canine pulmonary respiratory pathogens from a real-time polymerase chain reaction analysis was negative. Consequently, the dog was diagnosed with eosinophilic bronchopneumopathy. Clinical signs improved significantly within a few days after treatment with an oral corticosteroid.

Abstract : A 2-month-old intact female domestic short hair presented with physical abnormalities, including discharge of watery feces from the vagina, depression, and dehydration. The rectovaginal fistula and atresia ani type 3 were diagnosed on the vaginogram. During the anoplasty, the fistula could not be identified because the patient was too small. Instead of colotomy, feces were flushed out using a feeding tube. To prevent complications, a 1-cc syringe tip was sutured at the surgical site after the anoplasty. At the 3-month telephone follow-up after surgery, the cat was reported to have no further clinical signs.

Abstract : An 11-year-old, intact female, Miniature Poodle presented with an abdominal mass. The abdominal mass was located around the right fifth mammary gland. The surgically removed mammary mass was subjected to histopathological examination. Based on the microscopic interpretation, a final diagnosis of an intermediate grade infiltrative mammary comedocarcinoma was established. Computed tomography for metastasis evaluation after surgical resection of the tumor showed enlarged right medial iliac and right inguinal lymph nodes, and a micronodule in the accessory lung lobe, suggesting metastasis of the mammary gland tumor. Doxorubicin, a chemotherapeutic drug, was administered six times at three week intervals. However, despite chemotherapy, the masses around the fourth and fifth mammary gland on the right side enlarged in size, and the treatment was discontinued at the request of the owner. The anticancer response to mammary comedocarcinoma is poor and the patient is in hospice management. This is the first attempt to treat a case of canine mammary comedocarcinoma in South Korea.

Abstract : Two Korean short-haired cats were admitted to the Veterinary Medical Teaching Hospital, Chonnam National University, with severe lower lip avulsion. In the first case, the treatment was performed using the tension-free suture technique with rubber tube stents. The second case was treated using the tension-free suture technique with rubber tube stents for lip avulsion and using the cerclage wiring technique for alveolar fracture. The teeth around the alveolar fracture were extracted and bone graft and collagen membrane were applied at the alveolar fracture site to stabilize the mandibular alveolar fracture. Thereafter, the cerclage wire was placed circumferentially around the mandible. In both cases, normal function of the oral cavity was successfully recovered by repairing the anatomic abnormality. In conclusion, tension-free suture technique can be a treatment option for bilateral lower lip avulsion in cats.

Abstract : The current, retrospective study aimed to assess the short-term prognosis and postoperative complications associated with the surgical correction of elongated soft palate using harmonic scalpel and to compare the postoperative complications associated with the application of harmonic scalpel and traditional surgery using Metzenbaum scissors. Harmonic scalpel was used to perform staphylectomy in 21 dogs. A total of ten dogs underwent sacculectomy; six dogs with harmonic scalpel and four dogs using Metzenbaum scissors. Stenotic nares were corrected by wedge resection. Postoperative complications were recorded through monitoring and radiographic examinations. Telephone interviews were conducted on the first, third, and seventh day after discharge and continued until the resolution of postoperative complications. Postoperative edema at the surgical site was identified and mitigated within a day or two. Snoring and dyspnea improved dramatically in the group that underwent staphylectomy alone. Moreover, three dogs presented with postoperative gastrointestinal complications, especially retching. The symptoms persisted for seven days and ten days in two dogs that underwent sacculectomy with harmonic scalpel and for two days in one dog that underwent sacculectomy with Metzenbaum scissors. The clinical signs and symptoms of brachycephalic syndrome disappeared without recurrence. Harmonic scalpel provides a hemostatic effect during staphylectomy, is convenient, and does not cause postoperative complications. Conversely, the use of harmonic scalpel during sacculectomy necessitated a longer period for the resolution of complications without any significant hemostatic efficacy, compared to traditional surgery.

Abstract : A 1-year-old spayed female Scottish Fold cat presented with a 1.5-month history of vomiting, intermittent dyspnea, and abdominal distention. Radiographic, ultrasonographic, and computed tomographic examinations suggested a tentative diagnosis of a fluid-containing cystic mass with an internal septum. The mass was surgically removed. Histological examinations revealed that the mass was a non-neoplastic hepatic cyst. The patient had no recurrence of the cystic structure but died of acute renal failure 5 years after the surgery. This report describes the unusual case of a giant hepatic cyst with clinical signs that resolved after mass removal.

Abstract : A 12-year-old spayed female beagle dog was presented with pollakiuria and stranguria. Abdominal ultrasonography identified irregular a marginated, hyperechoic mass in the urethra and trigon area of the bladder. Computed tomography (CT) revealed a heterogeneous mass in the trigone area leading to a urethra. There was no evidence of regional or distant metastasis. Cytologic analysis suspected transitional cell carcinoma (TCC). The patient was treated with piroxicam, mitoxantrone, and once weekly fractionated radiation therapy (RT) with volumetric modulated arc therapy (VMAT). A follow-up CT scan at 6 months after RT revealed a reduction in tumor size. At 17 months after the start of RT, the patient became severely anorectic and lethargic. Ultrasound examination revealed a hyperechoic mass in the apex area of bladder while the trigone area of the bladder and urethra appeared normal. Multiple hypoechoic nodules of various sizes were found in the liver and spleen. The patient was humanely euthanized at the request of the owner. A combination of piroxicam, mitoxantrone, and hypofractionated RT with VMAT protocol was well tolerated. This case described tumor response and survival time of a canine TCC treated with piroxicam, mitoxantrone, and once weekly palliative RT using computer-assisted planning and VMAT.

Abstract : An 11-year-old male Rex rabbit (Oryctolagus cuniculus) had a rectal prolapse induced by a polypoid mass. The mass was highly vascularized with a cauliflower-like appearance. Anorectal papilloma was suspected, and fine needle aspiration cytology showed eosinophilic inflammation. After surgical removal of the polyp, postoperative care was given, such as systemic antibiotics and analgesics. In the re-examination, the rabbit was resolved, and there were no complications. Histopathological examination of the removed polyp indicated chronic eosinophilic proctitis to be the cause of the inflammatory condition of the protruding rectal polyp.

Abstract : Compared to the other chemodectoma, aortic body tumors, the carotid body tumor is rarer and more often malignant. In the present case, a 12-year-old, intact female Shih-tzu dog presented to the hospital with a right ventral cervical mass. The mass was diagnosed by immunohistochemical staining with chromogranin A (CgA) as a carotid body tumor. The cervical mass and metastasized lymph node were removed by surgical resection. Because the dog had valvular heart disease, chemotherapy with carboplatin was initiated over 6 months to prevent metastasis and recurrence as an adjunctive treatment. After over two years of management, tumor metastasis and recurrence were not observed until recently. This report shows that proper management and chemotherapy as an adjunctive therapy can treat carotid body tumors in elderly dogs with concurrent heart disease.

Abstract : A 3-year-old female Connemara pony was referred to Jeju National University Equine Hospital because of weight loss and prolonged anorexia. On admission, heart and respiratory rates were slightly elevated while body temperature was within the normal range. The color of the conjunctival and oral mucosa was yellowish pink. The blood chemistry results showed that total bilirubin, aspartate aminotransferase, and gamma-glutamyl transferase levels were remarkably elevated while blood urea nitrogen was within the reference range. Transcutaneous abdominal ultrasound revealed an enlarged right lobe of the liver with prominently increased parenchymal echogenicity, reduced hepatic vessels, and rounded caudal border. The pony was tentatively diagnosed with chronic hepatitis and icterus; rest and supportive treatments were provided. Clinical signs aggravated on day 2 with hind quarter paresis and cranial nerve signs such as circling, drooping, jerking, and head pressing against walls. Recumbency and generalized ataxia (grade 5/5) were shown on day 3. Plasma ammonia concentration on day 3 was as high as 656 μmol/L. Necropsy and histopathologic examinations strongly supported a diagnosis of hepatic encephalopathy. This case of hepatic encephalopathy exhibited rapid progress from low to terminal grade within 4 days in a Connemara pony. The results provide well-established clinical and pathological data for future application.
