ABSTRACT
A 6-month-old mature intact female Siamese cat presented with exertional dyspnea. Diagnostic studies revealed pleural effusion, grade 4/6 left basal systolic murmur, deep S-wave in electrocardiograph leads I, II, and III, cardiomegaly with pleural effusion on radiography, pulmonic systolic (~5.8 m/sec) and tricuspid (3.6 m/sec) regurgitant jets, atrial septal defect, and a hypoplastic right outflow tract. Based on these results, the case was diagnosed as pulmonic stenosis with atrial septal defect. To the best of our knowledge, this is the first case report describing pulmonic stenosis with atrial septal defect in a cat in Korea.

Canine heart worm disease is often life-threatening due to its various complications, including right side heart failure, caval syndrome and pulmonary eosinophilic granulomatosis. Several preventive medications and melarsomine have been developed and they are very effective to control heartworm infestation. However, in a case of severe infestation, melarsomine therapy often results in an unfavorable outcome because of the severe immune reaction caused by rapid killing of the adult worm. Surgical removal and an interventional method using flexible alligator forceps have been well described in the literature. Despite the usefulness of mechanical removal using flexible alligator forceps, the methodology still needs to be upgraded for increasing the applicability for treating dogs with severe infestation. We describe herein a newly developed percutaneous removal method for heartworms and this was successfully applied to 4 dogs with severe heartworm infestation. The follow-up studies also showed favorable outcomes with no complications.

The production of miniature animals has been suggested for use in organ transplantation. At present, many of the studies about application of animal organs to human have been focused on pigs because of the number of advantages involved and due to their similarities with human. However, a physiological analysis of the organs to be transplanted has not yet been carried out. Therefore, this study analyzed whether or not there were physiological and morphological differences in the hearts of conventionallyreared pigs and micropigs. In this study, the morphological and physiological functions of the heart were examined using radiographic and echocardiographic equipment. In the lateral radiographic view, the heart of the micropig has a larger cardiac long axis : short axis ratio than does the conventional pig, but the difference in the vertebral heart score was not significant. In addition, there were no morphological differences on the X-ray fluoroscopic view. There were no differences in echocardiographic values, except for several values in the left ventricle traces. Overall, it is expected that the values measured in this study will contribute to understanding of the physiological characteristics of micropigs.

A 3.5-year-old intact female miniature poodle (weighing 2.7 kg) was referred to the Veterinary Teaching Hospital at Kangwon National University, because of inadvertent aortic embolization, by an occlusion coil used for the closure of patent ductus arteriosus (PDA). The coil was found at the site of the branching renal arteries in the abdominal aorta. A foreign body forceps with a three-wire nail tip was used, with fluoroscopic guidance, to retrieve the coil. After the removal, the dog was treated with heparin to prevent thromboembolization.

Rhabdomyosarcoma is the most common sarcoma of children and adolescents. Rhabdomyosarcoma is a highly malignant soft tissue sarcoma that can arise in any site of the body containing striated muscle or its mesenchymal analogue. The common primary sites were head and neck including orbit, extremities, genitourinary tract, trunk, retroperitoneum, gastrointestinal tract, and thorax. There are basically three types of rhabdomyosarcoma: embryonal, alveolar, and pleomorphic; these categories may overlap histologically. Retroperitoneal rhabdomyosarcoma of embryonal type is rarely reported in an adult. Since we experienced a case of 25 X 20 X 12cm-sized retroperitoneal rhabdomyosarcoma of embryonal type, we report this with a review of literatures.

Early gastric cancer(EGC) is defined as carcinoma limited to the mucosa or submucosa, regardless of whether metastasis to lymph nodes have occurred, and the frequency of lymph node metastasis varies from 7 to 18%. The incidence of early gastric cancer has been increasing recently, probably with advance in the diagnostic procedure. Multiple gastric cancer, now cosidered to be a sort of multiple primary cancer by Moertels classification, is a special type of cancer in which two or more tumor lesions arise independently from the stomach. Multiple carcinoma was found in about 8.3% of 500 early gastric cancer cases at the National Cancer Center Hospital in Japan. In 77% of these, two lesions roexisted in the stomach. Coexistence of three lesions were found in 20% and more than four lesions in 3%. We report a case of multiple early gastric cancer of different histologic types in which two adenoma coexisted in the stomach.
