STATEMENT OF PROBLEM: Use of custom tray and tray adhesive is clinically recommended for elastomeric impression material. However there is not clear mention of drying time of tray adhesive in achieving appropriate bonding strength of tray material and impression material. PURPOSE: This study is to investigate an appropriate drying time of tray adhesives by evaluating tensile bonding strength between two types of polyvinylsiloxane impression materials and resin tray, according to various drying time intervals of tray adhesives, and with different manufacturing company combination of impression material and tray adhesive. MATERIAL AND METHODS: Adhesives used in this study were Silfix (Dentsply Caulk, Milford, Del, USA) and VPS Tray Adhesive (3M ESPE, Seefeld, Germany) and impression materials were Aquasil Ultra (monophase regular set, Dentsply Caulk, Milford, Del, USA) and Imprint II Garant (regular body, 3M ESPE, Seefeld, Germany). They were used combinations from the same manufacture and exchanged combinations of the two. The drying time was designed to air dry, 5 minutes, 10 minutes, 15 minutes, 20 minutes, and 25 minutes. Total 240 of test specimens were prepared by auto-polymerizing tray material (Instant Tray Mix, Lang, Wheeling, Il, USA) with 10 specimens in each group. The specimens were placed in the Universal Testing machine (Instron, model 3366, Instron Corp, University avenue, Nowood, MA, USA) to perform the tensile test (cross head speed 5 mm/min). The statistically efficient drying time was evaluated through ANOVA and Scheffe test. All the tests were performed at 95% confidence level. RESULTS: The results revealed that at least 10 minutes is needed for Silfix-Aquasil, and 15 minutes for VPS Tray Adhesive-Imprint II, to attain an appropriate tensile bonding strength. VPS Tray Adhesive-Imprint II had a superior tensile bonding strength when compared to Silfix-Aquasil over 15 minutes. Silfix-Aquasil had a superior bonding strength to VPS Tray Adhesive-Aquasil, and VPS Tray Adhesive-Imprint II had a superior tensile bonding strength to Silfix-Imprint II at all drying periods. CONCLUSION: Significant increase in tensile bonding strength with Silfix-Aquasil and VPS Tray adhesive-Imprint II combination until 10 and 15 minutes respectively. Tray adhesive-impression material combination from the same company presented higher tensile bonding strength at all drying time intervals than when using tray adhesive-impression material of different manufactures.

PURPOSE: The accuracy of CT in the detection of injuries of the solid visceral organ is well established, but the value of CT in diagnosing small bowel rupture after abdominal trauma is controversal. This study was conducted to ascertain CT finding of small bowel rupture result from abdominal trauma. MATERIALS AND METHODS: A retrospective analysis of preoperative abdominal CT findings in 40 patients was performed. Small bowel rupture was confirmed by surgery. Precontrast and postcontrast enhanced CT images were obtained in all patients. RESULTS: Diagnostic findings of small bowel rupture including pneumoperitoneum or retroperitoneal air, discontinuity of the bowel wall and extravasation of oral contrast materials were observed in 33 cases(83%). Intraperitoneal or retroperitoneal free air was seen in 31 cases(78%) and intraperitoneal or retroperitoneal free fluid collection was seen in 38 patients(95%). Small bowel wall was thickened in 31 cases(78%), bowel wall was enhanced in 12 cases(30%) and bowel wall discontinuity and extravasation of oral contrast material was seen in 5 cases, respectively. CONCLUSION: The CT scan is sensitive and effective modality for evaluation of small bowel rupture after abdominal trauma, because of high detectability of diagnostic and suggestive CT findings.

Injuries to the tarsometatsrsal joint are not common, and the results or treatment are often unsatisfactory. Whatever the severity of the initisl injury, prognosis depends on accurate reduction and its maintenance. 5 cases of fracture and dislocation of the tarsometatarsal joint were treated at Department of Orthopaedic Surgery, Capital Armed Forces General Hospital. The length of follow-up period ranged from 12 months to 18 months, with a mean of 15 months.

Malignant esophago-bronchial fistula is an incurable and distressing condition. The passage of swallowed saliva and solid or liquid food into the bronchial tree causes coqghing and frequent pulmonary infection and collapse. Most patients are unfit for major surgery, but intubation offers a quick, simple and effective treatment with improved length and quality of life. However, intubation with simple esophageal tubes are liable to result in failure to occlude the fistela, migration of the tube, erosion, and in the case of latex tubes, disintegration. To overcome these problems, the fistula is intubated perorally with a prosthesis surrounded by a foam rubber cuff contained ia silicone sheath, in which vacuum can be created. This cuffed prosthesis is the most satisfactory design for the treatment of malignant esophago-bronchial fistula with effiective and gentle occlusion of the fistula without risk of pressure necrosis. We experienced a case of the endoscopic treatment with a cuffed prosthesis for malignant esophago-bronchial fistula. So we report this case with brief review of the previous literatures.

Spontaneous internal biliary fistula is not an uncommon complication of neglected cholelithiasis, peptic ulcer, and carcinoma. The indidence, as given by various authors, differs but seems to vary between 3 and 5% of all cases of biliary disease. Until development of endoscopy, diagnosis has depended on the presence of air or barium in the biliary tree as radiologic findings or symptoms. Recently endoscopic examination, biopsy in appropriate case, and cannulation of the fistula for precise radiographic delineation will help to make a diagnosis. The main typesof fistulas are cholecystoduodenal, cholecystocolic, choledochoduodenal. Cholecystogastric or choledochogastric fistula is very rare type of internal biliary fistulas. Recently we encountered two cases who had suffered from fever and right upper abdominal pain with pneumobilia as ultrasonographic findings. They were confirmed as having cholecystogastric fistula, and choledochogastric fistula due to complicated gallstones by ERCP and surgical exploration. So we report two cases of biliary-gastric fistula of these patients with a review of relevant literatures.

PURPOSE: More effective diagnosis and treatment through a survey on clinical aspect for the last 5 years and interrelation between cold agglutinin titer and mycoplasma antibody titer of Mycoplasma pneumoniae pneumonia. METHODS: 369 patients hospitalized in the department of pediatrics of Chung Goo Sung Shim Hospital for the 5 years from January 1990 to December 1994 have been surveyed, which diagnosed to be Mycoplasma pneumoniae pneumoniaby physical findings or chest x-ray findings with the titer of 1:64 in cold agglutinin test or the titer of 1:80 in Mycoplasma antibody test or forefold increase of any one or both of 2 titers in follow-up tes RESULTS: 1) More cases were found in 1990(76 cases, 20.6%) and 1994(181 cases, 49%) and the monthly distribution showed irregular fluctuations. Male to female ratio was 1:1.2 and high incidence was in the age of 3 to 5 years(27.9%), but 46 cases(12.5%) affected the infants below 1 year old. 2) Cough, fever, sputum were the most chief complaints. More moist rales, pharyngial injection, wheezing were found in physical examination. 86.7% of pneumonic infiltration were found in x-ray findings, 35.8% of which were both lung infiltration. The most common affected site was Rt. lower lobe and then Lt lower lobe and then followed by Rt. upper lobe. 71.8% of the whole cases were hospitalized for 5-8 days. 3) EM administration started 10-12 days after the onset in 29.3%. Mean duration of hospitalization of the cases administrated within 6 days from onset was 7.5+/-2 days, which was shorter than 8.4+/-3.5-that of the cases administrated after 6days from onset. The observation on those duration meant little atatistically(p>0.1) 4) The measure of Mycoplasma antibody titer in 142 cases among 245 positive cold agglutinin test case showed 61.3% of positive ratio. Positive ratio of cold agglutinin test peaked from 13th to 15th day after onset(89%) and went down(33%) after 19th day. Positive ratio of Mycoplasma antibody titer was at its summit(91%) from 7th to 9th day and went down(63%) after 16th day. decreased to 63% after 16 days. 264 cases tested simultaneously for cold agglutinin titer and Mycoplasma antibody titer. Titers of each simultaneous test for cold agglutinin and Mycoplasma antibody were in proportion each other(p<0.005, N=264, r=0.51). CONCLUSIONS: Mycoplasma pneumoniae pneumonia prevailed every 4 years(1990, 1994) and monthly distribution had been irregular. The most cases were found at age of 4 and 5. Mycoplasma antibody titer seems more effective for early diagnosis for Mycoplasma antibody titer showed high positive rate earlier and the rate went down earlier than cold agglutinin titer. The earlier diagnosis and treatment are required because of tendency of later erythromycin administration.

Leiomyosarcomas of the stomach are unusual tumors, accounting for 1% to 3% of all malignant tumors and 17% to 20% of all smooth muscle tumors of the stomach. It is difficult to diagnosis these tumors preoperatively because of its vague symptoms and signs or producing symptoms only late. Despite their rarity and difficulty in diagnosis, thier diagnosis is important due to more favorable prognosis aasociated with these tumors than that of gastric carcinoma. Recently, endoscopy is being used with increasing frequency, but because these are submucosal lesions the diagnosis of thease tumors cannot be easily made through the endoscope. We experienced a case of relatively full-brown leiomyosarcoma in gastric fundus. Endoscopy showed 6x6cm sized, definite margined, protruding mass on gastric fundus, with central deep ulceration coated with blood clots. The mucosa overlying the mass was intact, smoothly effaced and the bridging fold was also visible. Postoperative ultrasound showed large protruding mixed echogenic solid mass with contral deep excavation due to ulcer, and intact serosa, so suggestive of endogastric tumor. We believed endoscopy combined with endoscopic ultrasound is probably useful method in early diagnosis of gastric submucosal tumors, especially exogastric type or early small tumors

BACKGROUND: The percutaneous pleural needle biopsy have been regarded as cornerstone in the diagnosis of lymphocyte dominant pleural effusions of which acid fast bacilli smear and cytologic exam was negative. However, the complications of percutaneous pleural needle biopsy is not rare arid its diagnostic efficacy is not always satisfactory. Recently, pleural fluid adenosine deaminase (ADA) and carcinoembryonic antigen (CEA) are widely accepted as markers of tuberculous pleurisy arid malignant pleural effusion respectively. We designed this study to re-evaluate the role of percutaneous pleural needle biopsy in the diagnosis of lymphocyte dominant exudative pleural effusions whose APE smear, cytologic exam was negative. METHODS: Retrospective analysis of 73 cases of percutaneous pleural needle biopsy in case of lymphocyte dominant exudative pleural effusions whose AFB smear and cytoloic exam was negative from Jan 1994 to Feb 1996 was done. RESULT: In 35 cases, specific diagnosis was obtained(all cases were tuberculous pleurisy), arid in 3(1 cases specific diagnosis was not obtained in spite of getting adequate pleural tissues, and in the other 8 cases, percutaneous pleural biopsy failed to get pleural tissues. In 9 cases, complications were combined including pneuomothorax and hemothorax. All 49 cases of pleural effusions whose ADA value was higher than 40IU/L and satisfying other categories were finally diagnosed as tuberculous pleurisy, however, the pleural biopsy confirmed only 28 cases as tuberculous pleurisy. In 6 cases of pleural effusions of which CEA value is higher than l0ng/ml, the pleural biopsy made specific diagnosis n no case. Final diagnosis of above 6 cases consisted of 4 malignant of fusions, I malignancy associated effusion and I tuberculous pleurisy. CONCLUSION: In the diagnosis of 73 cases of lymphocyte dominant pleural effusions of which acid fast bacilli smear and cytologic exam was negative, percutaneous pleural biopsy diagnosed only in 35 cases. In the diagnosis of tuberculous pleurisy, the positive predictive value of higher ADA than 40 IU/L in lymphocyte dominant pleural effusion with negative AFB smear and negative cytologic exam was l00%. And the diagnostic efficacy of pleural biopsy was 57%. In cases of effusions with high CEA than 10ng/ml 83% and 0% respectively. Finally, we concluded that percutaneous pleural needle biopsy in the diagnosis of APE smear negative and cytologic exam negative lymphocyte dominant exudative pleural effusion was not obligatory especially in effusions with high ADA and low CEA value.

Gallstone pancreatitis is caused by migration of gallstones through the common bile duct and ampulla of Vater, where ohetruction or impaction may occur. Early detection and endoscopic treatment of impacted gallstones are very important for the amelieration of pancreatitis. Pancreatic imagings, such as conventional ultrasonography, computerised tomography(CT) and endoscopic retrograde cholangiypancreatography(ERCP) have beea used for the diagnosis of gallstone pancreatitis. But these imaging net are often unsatisfactory fordetection of the impacted gallstones in the common bile duct ampulla of Vater. Especially ERCP has been contraindicated in acute pancreatitis. Endoscopic ultrasonography(EUS), which was recently developed, has been known as highly accurate diagnostic tool in the diagnosis of biliary and pancreatic disease. The high resolution of EUS is capable of showing unique morphological detail in gallstone pancreatitis. We report 3 cases of gallstone pancreatitis which Was accurately diagnosed by EUS and successfully treated by endoscopic treatment.
