Study purposes were to evaluate ultrasonographic characteristics of transitional cell carcinoma (TCC) and quantitate bladder tumor size in dogs. Heterogeneous mass, wall involvement, and broad-based attachment were significantly associated with TCC, but not prominently the trigone region. Mass size evaluation revealed a significant correlation between progressive disease (PD) in TCC patients with piroxicam therapy. Largest diameter of target lesion/body weight (cm/kg) ratio showed a high mean value in PD. A value > 0.3 was associated with PD with 83% sensitivity and 66% specificity. The results suggest that ultrasonography can provide evidence for diagnosing and predicting a prognosis for TCC.

We have observed 360 cases of spontaneous pneumothorax from January 1980 to May 1991 at the department of Thoracic and Cardiovascular Surgery, Chosun University Hospital. Males occupied 266 cases[73.9%] and females 94 cases[26.1%], and its ratio was 2.8: l. The age of patients ranged from neonate[5 days] to 84 years old. The site of pneumothorax was right in 50.3%, left in 43.3% and bilateral in 6.4%a. The clinical symptoms were frequently dyspnea, chest pain and coughing. The associated pulmonary lesions were shown pulmonary tuberculosis in 199 cases[55.3%], bullae in 54, pulmonary emphysema in 31, COPD in 17, pneumonia in 6, lung cancer in 5, paragonimiasis in 5, catamenial pneumothorax in 3 and unknown underlying pathology in 39 cases. The results of surgical management of spontaneous pneumothorax are followings: 288 out of 360 cases[80.0%] were cured by closed thoracotomy, 53 cases[14.8%] were cured by open thoracotomy. Open thoracotomy was the most effective procedure in persistent air leakage, recurrent pneumothorax, visible bleb or bullae on the chest X-ray, associated lesion, bilateral simultaneous pneumothorax, parenchymal incomplete lung expansion and bleeding after closed thoracotomy. The incidence of complication was developed in 10. ado and recurrent rate was seen in 10.6%. There was no operative death.

Gastrointestinal duplications are rare congenital malformation that may require surgical intervention in the neonate, infant, and occasionally the older child. Symptoms produced by duplications vary according to their location, size, type and histology. We report the clinical characteristics and the surgical results of 9 cases of the gastrointestinal duplications treated at at Asan Medical Center between 1989 and 2000. Five patients were boys and four were girls; age of patients ranged from 5 days to 10 years. Eight duplications were cystic and one was tubular. One involved the stomach; five were in the ileum, and two in the cecum. The most common presentation was intestinal obstruction. There was associated anomaly in one patient, pulmonary sequestration and double ureter. Ectopic gastric mucosa was found in two. All patients underwent surgical resection. There was no perioperative mortality or morbidity. Although gastrointestinal duplication is a rare entity. consideration of associated anomalies and being familiar with the anatomy and clinical features are required for adequate management. In cystic form. complete excision is recommended but planned surgery is required for long segment tubular lesion.

Split cord malformations (SCMs) usually present in childhood, and are rarely reported in adults. And also, a cervicothoracic SCM associated with tethered cord syndrome has very rarely been reported in the literature. We report a case of SCM associated with tethered cord and spina bifida in an adult. This report describes the case of a 34-year-old woman who presented for evaluation of neck pain, back pain, and intermittent paraparesis of several months duration. The MRI and CT showed a SCM at the cervicothoracic level and a fibrous septum at the thoracic level. She underwent surgery for the SCM and tethered cord syndrome, and was followed for 7 years. Patient presented complete recovery in the follow-up. The authors discuss this unusual lesion and describe the anatomical relationship of the level of cord duplication and fibrous septum.

Chronic viral infection has been reported to cause a range of hepatic lesion, including hepatic fibrosis, cirrhosis and hepatocellular carcinoma (HCC) in a wide variety of animal species. Woodchucks (Marmota monax) chronically infected with woodchuck hepatitis virus (WHV) develop similar progressive hepatic inflammatory and neoplastic lesions that are remarkably similar to those associated with HBV infection in humans. Twenty two-month-old offspring from woodchucks (Marmota monax) experimentally infected with woodchuck hepatitis virus, were purchased. One randomly chosen animal was autopsied. The liver exhibits marked cirrhotic changes characteristic of the pre-transformation phase of WHV. We believe that this may represent a new suitable and cost-effective model for the disease processes associated with hepadnaviruses in a number of other species, most notably Hepatitis B virus infection in man.

회전근 간의 질환은 과거 강직과 불안정성에 대한 연구가 주종을 이루었다. 동결견에 대한 치료로 회전근 간을 절제하는 것도 치료의 한 방법으로 사용되어 왔다. 불안정성에 대한 치료 중 회전근 간의 봉합술은 아직은 다른 치료 방법을 시행하고 추가적인 관절 운동 범위의 감소가 필요할 때 사용할 수 있는 보조적인 방법으로 사용하는 것이 좋을 것으로 보인다. 그 외의 회전근 간 자체 파열 등의 병변이 발생할 수 있으므로 수술시 반드시 확인해야 하는 구조물로 사료된다.

A 19-year-old Korean woman presented with left mandibular dental pain and swelling. Periapical radiolucencies were associated with the mandibular left first molar, second molar and the mandibular right second molar. The mandibular right second molar root developed incompletely and has the open apex. Clinical examination revealed worn accessory occlusal cusps of premolars. A diagnosis of dens evaginatus with associated periapical lesion secondary to pulpal necrosis was made. The root canal of the lower right second premolar was sealed with Calcium hydroxide paste for apexification. About two months later Calcium hydroxide paste was removed and the canal was resealed with new Calcium hydroxide paste. After four months the canal was sealed permanently with guttapercha and zinc oxide-eugenol sealer. The root canals of the lower left premolars were irrigated every week with 3.5% NaOCl solution for and half month. And the canals were sealed with gutta-percha and ZOE sealer. Preventive endodontic treatment for the lower right first premolar was undertaken.

Brain abscess commonly occurs secondary to an adjacent infection (mostly in the middle ear or paranasal sinuses) or due to hematogenous spread from a distant infection or trauma. Pulmonary arteriovenous fistulas (AVFs) are abnormal direct communications between the pulmonary artery and vein. We present two cases of brain abscess associated with asymptomatic pulmonary AVF. A 65-year-old woman was admitted with a headache and cognitive impairment that aggravated 10 days prior. An magnetic resonance (MR) imaging revealed a brain abscess with severe edema in the right frontal lobe. We performed a craniotomy and abscess removal. Bacteriological culture proved negative. Her chest computed tomography (CT) showed multiple AVFs. Therapeutic embolization of multiple pulmonary AVFs was performed and antibiotics were administered for 8 weeks. A 45-year-old woman presented with a 7-day history of progressive left hemiparesis. She had no remarkable past medical history or family history. On admission, blood examination showed a white blood cell count of 6290 cells/uL and a high sensitive C-reactive protein of 2.62 mg/L. CT and MR imaging with MR spectroscopy revealed an enhancing lesion involving the right motor and sensory cortex with marked perilesional edema that suggested a brain abscess. A chest CT revealed a pulmonary AVF in the right upper lung. The pulmonary AVF was obliterated with embolization. There needs to consider pulmonary AVF as an etiology of cerebral abscess when routine investigations fail to detect a source.
