A 13-year-old, spayed female, Yorkshire terrier was presented with a history of vomiting and diarrhea. Radiographic and ultrasonographic studies suggested rupture of right renal cyst. Left kidney had increased cortical echogenecity with indistinct corticomedullary junction on sonogram. Unilateral nephroureterectomy of right kidney was performed. Histopathologic examination of the resected renal mass confirmed a renal cystadenocarcinoma. To the best of our knowledge, it is the first case report of renal cystadenocarcinoma in a small breed dog in Korea.

Pancreatic pseudocyst is one of the most common pancreatic mass lesions developed following acute or chronic pancreatitis. Two dogs were presented with nonspecific clinical signs such as abdominal pain, vomiting and depression and diagnosed as pancreatic pseudocysts through percutaneous ultrasound-guided aspiration. Pancreatic pseudocyst may contain pancreatic juice, so leads the deteriorate state of patient through pertinent inflammation and autodigestion of pancreas. In this study, the clinical signs and pancreatic lesion were improved after aspiration. Percutaneous ultrasound-guided aspiration can provide the diagnostic information through cytology and lipase and amylase concentration, and be selected as the first choice for treatment.

A 2-year-old, castrated male, Scottish fold cat was referred to Veterinary Medical Teaching Hospital of Seoul National University (VMTH-SNU) for evaluation of acute bilateral blindness after general anesthesia. For dental prophylaxis in local animal hospital, general anesthesia had been induced with intravenous acepromazine and ketamine, and maintained with isoflurane after intubation. At VMTH-SNU on next day, complete blood count, electrolytes and serum chemistry values were within normal ranges. On neurologic examination, visual placing and postural reactions like as hopping, hemiwalking and wheelborrowing were reduced on right hindlimb. On ophthalmic examination, menace responses were absent on both eyes and pupillary light reflex (PLR) reduced on right eye, but other reflex and fundus were normal. Prednisolone (2 mg/kg sid for 3 days) was administrated orally and tapered. Visual placing was possible on 2nd day, and postural reactions were recovered on 4th day after dental prophylaxis. Based on the process and recovery, this case was considered as postoperative visual loss (POVL) after general anesthesia.

A Maltese was presented with a subcutaneous mass at right flank, depression and hyperthermia. Ultrasonography revealed a hypoechoic mass with hyperechoic foci, a defect of abdominal wall and peritonitis. In cytology, fat necrosis was found. This dog was diagnosed as chronic suppurative steatitis secondary to pancreatitis and pancreatic herniation through surgery and histopathologic examination. Steatitis is recurrent inflammation and necrosis of adipose tissue. Also steatitis associated with pancreatic diseases such as pancreatitis and pancreatic tumor was reported and direct fat necrosis by pancreatic enzyme was supposed as the etiology. Steatitis secondary to pancreatitis was rarely reported in dogs and there was difficulty in diagnosis and treatment. This case has a limitation that pancreatitis was not diagnosed as underlying cause to steatitis before surgery. However, a defect of abdominal wall and peritonitis were observed on ultrasonography. Good prognosis could be achieved through prompt surgery and medical treatment.

The emergence of bacterial resistance to antibiotics during therapy is a matter of great problem in clinical medicine. This may be because many veterinarians have used inappropriate antibiotics without bacteriological culture. Therefore, the purpose of this study is to determine isolation of anaerobic bacteria as pathogens from veterinary clinical specimens as well as susceptibility pattern for choosing antibiotics. Various anaerobic bacteria were isolated from clinical specimens of dogs, cats, rabbits at Veterinary Medical Teaching Hospital of Seoul National University from May 2001 to October 2002. The total number of isolated anaerobic bacteria was 13 isolates; Bacteroides spp. (3 isolates), Fusobacterium spp. (2 isolates), Peptostreptococcus spp. (2 isolates), Porphyromonas gingivalis (2 isolates), Prevotella spp. (3 isolates), and Propionibacterium acnes (1 isolate). For evaluating the antibiotic susceptibility patterns of the isolates disk diffusion method was used. All isolates were susceptable to all tested antibiotics except only one Fusobacterium varium was resistant to norfloxacin.

A 14 kg, 9-year-old, spayed female, Cocker Spaniel was presented to the Veterinary Medical Teaching Hospital of Seoul National University with a history of head tilt and circling. Otitis externa and media were diagnosed by computerized tomography, and total ear canal ablation was performed. In preanesthetic evaluation, systemic hypertension and second-degree atrioventricular block were observed, but there was no regurgitation through the heart valves. Systemic hypertension was managed with amlodipine (0.1 mg/kg, PO, BID) for the anesthesia. The dog was premedicated with cefazolin (22 mg/kg, IV) and midazolam (0.2 mg/kg, IV). Anesthesia was induced with alfaxalone (2 mg/kg, IV) and maintained with isoflurane and 100% oxygen following intubation. During surgery, vital signs (heart rate, respiratory rate, blood pressure, end tidal carbon dioxide partial pressure and body temperature) were maintained within normal ranges, but bradycardia was observed and corrected with glycopyrrolate (5 ug/kg IV, twice). During subcuticular suture, electrohemostasis was applied at the incision line, which was close to the trigeminal nerve. In no time at all, heart rate dramatically decreased from 110 to 60 beats per minute. No additional treatment was done because mean blood pressure was maintained above 70 mmHg. The heart rate recovered according to the decrease of end tidal isoflurane concentration and there were no complications associated with the anesthesia and surgery. Sudden bradycardia after electrical stimulation around the trigeminal nerve was considered as trigeminocardiac reflex (TCR). It is recommended to be careful of bradycardia from TCR when electrocautery is used in the craniofacial area during surgery.
