Radiographic findings of degenerative joint disease (DJD) in the coxofemoral joints were studied in 108 dogs referred to Veterinary Medical Teaching Hospital, College of Veterinary Medicine, Seoul National University. Radiographic findings were identified with a extended ventrodorsal projection. Clinical signs such as pain in the affected joint, exercise intolerance, lameness, crepitation on flexion and extension of the joint and decreased range of motion, were shown in 40% and radiographic changes of bilateral coxofemoral joints were identified in 69% of a group of dogs. There are no sex predilections. Thirty-seven dogs were diagnosed as canine hip dysplasia (CHD; 10 cases), avascular necrosis of the femoral head (Legg-Calves-Perthes disease [LCPD]; 12 cases), fracture of the acetabulum (1 case), luxation(10 cases) and subluxation (15 cases), however, luxation and subluxation were identified in 11 dogs affected with CHD and LCPD. Causes of DJD in others (71case) were not identified. Radio-graphic findings identified included osteophyte formation at the attachment of the joint capsule (70%), sclerosis of the subchondral bone of the cranial acetabular edge (47%), remodeling of the femoral head (34%), thickening of the femoral neck(31%), perichondral osteophyte formation (31%), joint laxity (30%) and so on. All of the dogs diagnosed as CHD were large breed such as Retriever, Germain Shepherd, and Weimaraner and their age was under 1 year. This condition occurred bilaterally in 70% of affected animals. Dogs diagnosed as LCPD were young (under 1 year), small breed dogs. The incidence of LCPD is greater in Yorkshire Terrier, Miniature Pinscher and Poodle. This condition occurred unilaterally in 67% of affected animals. Clinical signs of dogs with unknown cause were shown in 15% and this condition occurred bilaterally in 75% of affected animals. Radiographic findings varied with patient's age and breed, however, the most common finding was osteophyte formation at the attachment of the joint capsule.

Fourteen dogs referred to veterinary Medical Teaching Hospital, Seoul National University were diagnosed as esophageal foreign body (9 cases), megaesophagus (4 cases) and esophageal stricture (1 case). Patients showed a variety of clinical signs including regurgitation, vomiting, anorexia, hypersalivation, and retching. Survey radiographic examination included the entire esophagus, including the caudal pharynx and cranial abdomen. contrast radiographs were done to identify lesions or to characterize abnormal radiographic findings on survey films. In case static contrast studies were not sufficient were not sufficient to differentiate the diseases, dynamic fluoroscopic studies were performed. In thoracic megaesophagus, when gas filled, it provided several hallmark findings such as visualization of paired longus colli muscle and tracheal stripe sign. When gas-distended, the caudal thoracic esophagus was seen as a pair of thin, soft-tissue stripes that converged into a point overlying the diaphragm and cranial abdomen. All cases of megaesophagus could be solely identified by survey radiographs. In esophageal foreign body, 6 cases out of 9 patients had the history of having foreign body and others not. Most of esophageal foreign body could be diagnosed on survey radiographs and one case with radiolucent foreign body was confirmed by esophagram. It appeared as radiopaque material along the path of esophagus and the radiopacity was determined by its nature. Obstruction caused by foreign body eventually led to dilation of the esophageal lumen cranial to the site in 3 cases. In esophageal stricture, there was no remarkable findings on survey radiograph of the thorax. However, esophagography with barium sulfate showed the narrowing of the esophagus near hiatus. On fluoroscopy, swallowed barium was stagnated cranial to the site despite the esophageal peristalsis.

A 3-year-old, 38 kg, male Golden Retriever dog was referred to Veterinary Teaching Hospital of Konkuk University because of chronic formation of crust on nasal bridge and planum nasale. Abnormalities of physical examination included hyperkeratosis on the footpad, symmetrical alopecia and erythma around olecranon, and crust on nasal bridge and planum nasale. Results of the hematological examination showed a mild leukopenia with neutropenia, monocytosis, and mild lymphocytosis. In addition, the result of serum chemistry and thyroid gland profile were normal. Results of fungal and bacterial culture was negative. Acanthocytes in cytological evaluation of nasal crust were observed in direct microscopic examination. Examination of skin biopsy exhibited vacuolation of basal cell layer, degeneration and necrosis of basal cell with defluxion, mild monocytes filtrations between epidermis and dermis, and mild acanthosis with hyperkeratinization. Based on results of examination described above, Discoid Lupus Erythematosus (DLE) was diagnosed.

A 7-year-old female, Jindo dog was referred to the Veterinary Teaching Hospital with mild dyspnea and anorexia due to a gunshot trauma. The dog was wounded in the thoracic region 3 days ago. Plain radiographs showed the left 8th rib fracture, interstitial pattern in the left caudal lung field and pleural effusion. Abdominal radiographs showed the lead bullet. Computed tomographs(CT) showed the size of pulmonary contusion, laceration, lung parenchymal injuries, hemothorax and perforation of abdominal wall. The therapeutic plan was based on abnormalities seen on CT scans but not clearly seen in survey radiographs. Thoracic CT significantly provides even more informations compared with the corresponding radiographs in thoracic gunshot trauma. Although thoracic survey radiographs are useful as a screening tool, CT is highly sensitive in detecting thoracic injuries after thoracic trauma and is superior to routine thoracic survey radiographs in visualizing lung contusion, pneumothorax and hemothorax. Therefore, we recommend CT in the initial diagnostic work-up of patients with thoracic injuries and with suspected chest trauma because early and exact diagnosis of all thoracic injuries along with sufficient therapeutic consequences may reduce complications.

An 8-year-old, male Shih-tzu dog with clinical signs of hemorrhage from penile orifice and pain on lifting hindlimb was brought to the Veterinary Medicine Teaching Hospital, Chungnam National University. The patient was shown polyuria/polydipsia (PU/PD), more than 10 times per day, and gasterointestinal signs such as intermittent vomiting and melena. On laboratory examination, BUN, creatinine and amylase level were all highly increased. Radiographic and ultrasonographic findings included that both kidneys were abnormal, and both prostates were hyperplastic bilaterally and cysts were presented in parenchyma. Additionally, hyperechoic pancreas and intact urinary bladder were observed from ultrasonographic examination. The dog was diagnosed as pancreatitis, acute renal failure and benign prostatic hyperplasia (BPH). After the appropriate treatment for pancreatitis and acute renal failure, He dog was treated with administration of azasteroid for BPH. On day 71 after azasteroid treatment, good response to the treatment was defined by ultrasonography and clinical signs cured completely.

The purpose of this study was to compare the long term prognosis of Ahmed valve implantation and medical therapy in dogs with early primary glaucoma. The medical records of dogs with early primary glaucoma from the Veterinary Medical Teaching Hospital of Seoul National University between January 2005 and May 2008 were reviewed. Five dogs underwent Ahmed valve implantation and medical therapy was performed in six dogs. Breeds of the dogs included Shih Tzu(n = 7), American cocker spaniel(n = 2), and miniature poodle(n = 2). Adequate intraocular pressure(IOP) was better maintained in the Ahmed valve implantation group than in the medical treatment group throughout the follow-up period. Mean time for vision loss to develop after treatment in the Ahmed valve implantation group($198.0{\pm}115.4$ days) was significantly longer than that in medical treatment group($43.2{\pm}30.4$ days, p < 0.05). Post-operative complications included occlusion of the tube by fibrin in the anterior chamber (n = 1), fibrous capsule about the episcleral base of the device(n = 1), and dislocation of the valve body(n = 1). It is considered that Ahmed valve implantation is more effective strategy to control IOP and maintain vision than medical treatment in early glaucomatous dogs.
