This report describes clinical cases of a palato-gingival groove on a maxillary lateral incisor with associated localized periodontal disease and pulp necrosis. The tooth of the first case was extracted because of severe bone destruction. The palato-gingival groove of the second case was eliminated using a round bur, and the resulting defect was filled with synthetic graft and covered by an absorbable membrane. Both diagnosis and treatment of palato-gingival groove were very difficult and usually extraction of the involved tooth is the treatment of choice, but combined endodontic-periodontic treatment allowed the tooth to be saved.

Objectives: Endoscopic variceal ligation is well established metbod of treatment for esophageal varices whereas for gastric varices there has not been any systematic report of its use as a method of treatment. To evaluated its possible clinical application, the band ligation(banding) and the method of band ligation in conjuction with submucosal ethanolamine injection(banding with sclero) were tested on canine stomach, and results were assessed.

Early and longterm prognosis depended on the extents of acute myocardial infarction and residual myocardial function. Many clinical methods have been evaluated to determine their ability to estimate the size of myocardial infarcts. But because of many disadvantages simplified QRS scoring system, used with standard 12-lead EKG, was developed, which is noninvasive, inexpensive and easily releatible. Therefore, the correlation between QRS and peak CK,killip classification were evaluated in 55 patients with initial acute myocardial infarction at the Chung-Ang University, Yong-San and Pil-Dong Hospital during the period from January 1983 to December, 1986. The results were as follows : 1) The average QRS score of the anterior wall infarction is 7.1 and that of the inferior wall infarction is 4.5 and there is a statistical significance(p<0.01). 2) In the acute myocardial infarction, the correlation coefficeient between the QRS score and the killip classification is 0.66(p<0.05). 3) In the acute myocardial infarction, the average QRS score is 6.3 and the correlation coefficient between the leak CK and the QRS score is 0.52(p<0.05). 4) In the anterior wall infarction, the average QRS score is 7.1 and the correlation coefficient between the peak Ck and QRS score is 0.48(p<0.05). 5) In the inferior wall infarction, the average QRS score is a 4.5 and the correlation coefficient between the leak CK and QRS score is 0.79(p<0.05).

Carcinosarcoma is a rare malignant neoplasm consisting of both epithelial and nonepithelial components, that is, carcinoma and sarcoma in the same tumor. Since Queckenstedt reported the case of carcinosarcoma of the stomach in 1904, only 30 cases have been reported. We present a case of carcinosarcoma and adenocarcinoma of the stomach in 63-year-old man with the review of the literature.

PURPOSE: To evaluate the CT findings of pleural dissemination in primary lung cancer and the limitations of CT scanning in detecting pleural dissemination in primary lung cancer. MATERIALS AND METHODS: Primary lung cancer with pleural dissemination was diagnosed in 68 patients and confirmed by pleural biopsy, cytology and surgery, and these cases were the subject of this study. Adenocarcinoma accounted for 49, squamous cell carcinoma for 13 and small cell carcinoma for six. Eight CT features, namely the amount of pleural effusion, the contour, extent andlocation of pleural thickening, the shortest distance between pleura and mass, pleural calcification, pleural tailsign and the extent of extrapleural fat proliferation, were evaluated. RESULTS: Pleural effusion was noted in 51 of 68 patients(75%), though in most cases(70%), the amount of this was small. Among 42 patients(62%) in whom thickened pleura, were noted, pleural thickening was thin and irregular in 22(52%), thick and irregular in 16(38%), and thin and regular in 4(10%). The extent of pleural thickening was multifocal in 22 patients(52%),diffuse in 16(38%), and circumferential and single in two(5%). Pleural thickening was more frequently noted at theposterior than the anterior pleura. Pleural abutting was seen in 53 patients(78%). In ten patients(15%), chest CTscans revealed no perceptible pleural abnormalities. CONCLUSION: If in primary lung cancer, the primary lung masscontacts the pleura, and if pleural thickening, even when slight, shows marginal irregularity, pleuraldissemination should be considered. Although CT scanning is very useful for the detection of pleural disseminationin primary lung cancer, about 15% of patients showed no perceptible pleural abnormalities. Other diagnosticmodalities such as thoracoscopy are mandatory for the correct diagnosis of pleural dissemination in primary lung cancer.

BACKGROUND: To analyze the morphologic characteristics of low density lymph node in etiologic differentiation of lymphadenopathy, emphasizing the different features between tuberculosis and lung cancer, on contrast enhanced CT scan,. METHOD: A total of 64 patients who showed low density lymph nodes on chest CT scan were analyzed. Primary causes were tuberculosis (n=28), lung cancer (n=27), malignant lymphoma (n=5) and metastasis from extrathoracic malignancies (n = 4). CT scan was performed with 10mm slice thickness and 7 characteristic features were evaluated: location,size, presence or absence of the nonnecrotic lymph node, calcification, perinodal fat obliteration, thickness and evenness of the enhancing rim. RESULTS: In patients with tuberculous lymphadenopathy, lymph nodes with uneven (68.0%) and thick (62.1%) enhancing rim were more common than lung cancer (p<0.05). Low density lymph nodes with less than 1cm in size were found only in tuberculous lymphadenopathy(n=10). In 48.2% of patients with lung cancer, more than 1 nonnecrotic enlarged lymph node were coexisted, whereas 21.4% in patients with tuberculous lymphadenopathy(p=0.06). However, the size, location and calcification were not statistically significant between tuberculous lymphadenopathy and lung cancer. CONCLUSION: Tuberculous lymphadenopathy is strongly suggested when enhancing rim of enlarged lymph nodes is uneven and thick, when the coexisting nonnecrotic lymph nodes are few in number and when central low density is encountered in normal sized lymph nodes.

Esophageal perforation is a rare disease, which require emergent diagnosis and therapeutic procedure. In this paper, we present one case of esophageal perforation by traction of toothbrush which was swallowed during pharyngeal irritation. After the toothbrush was inserted to stomach by gastroscope, gastrostomy was performed for removal of toothbrush and the esophageal perforation was repaired by operation.

PURPOSE: To analyze angiearchitecture of arteriovenous malformations(AV malformation) in order to clarify the angiegraphic risk factors for intracerebral hemorrhage and other nonhemorrhagic symptoms. MATERIALS AND METHODS: Eighty-five patients with angiegraphically-proved brain arteriovenous malformation were included in this study. Retrospective review of clinical history and angiography was done. Topographic analysis and evaluation of 17 angiearchitectural characteristics were conducted. RESULTS: Deep-seated and cortico-callosal type, small nidus size, intranidal pouch, one draining vein, deep venous drainage only venous stenosis and venous aneurysm were the most discriminating or predictive characteristics of hemorrhage in brain arteriovenous malformation. And those with large nidus size, dural supply and venous hypertension were correlated with nonhemorrhagic symptoms such as seizure, headache and neurologic deficit. CONCLUSION: Detailed analysis of the angiearchitecture of brain arteriovenous malformations is needed to identify the features that are correlated with prognostic implications for the treatment of patients with ^V malformations.
