PURPOSE:To evaluate the role of unenhanced CT in diagnosing the acute appendicitis. METHOD AND MATERIALS: We retrospectively analyzed conventional contrast-enhanced abdominal CT scans of 197 normal patients and barium enemas of 26 out of the 197 patients. Additional unenhanced CT scans of right lower abdomen were performed on 30 patients who were suspected of having acute appendicitis;barium enema was performed in 26 patients. RESULTS: in the analysis of the conventional CT scans, we could detect 132(67%) normal appendicies. On barium enema of 26 out of 197 patients, abruptly narrowed appendix was visualized in 5 cases and luminal irregularity in 4 cases but all 26 cases showed normal appendix on CT. In the 30 cases of unenhanced CT, all appendicies were visualized. Among 12 Cases which were proved as acute appendicitis, barium enenma was done in 10 case;abruptly narrowed appendix was shown in 3 and luminal irregularity in 1. Among 18 cases which were diagnosed as normal appendix, nonvisualization of appendix' was in 1 case, abruptly narrowed lumen in 3, and luminal irregularity in 9. CONCLUSION:Unenhanced CT in the area of the cecum may be an effective and safe diagnostic tool for acute appendicitis.

Granulosa cell tumors are uncommon neoplasm of ovary that are characterized by their long natural history and for their tendency to recur years after an aparrent clinical cure. Endometrial cancer occurs in association with these tumor in at least 5% of cases and 25%-50% are associated with endometrial hyperplasia. In this study, we present a case of granulosa cell tumor of right ovary with endometrial cancer after left oophrectomy.

OBJECTIVES: The purpose of this study was to investigate the risk factors in veterans for posttraumatic stress disorder and to find the correlation between the disorder and the characteristics of the variables. METHODS: We compared the risk factors in veterans between 40 diagnosed PTSD patients and 78 controls, using psychiatric by psychiatrists and measurement instruments such as CES, Mississippi scale, and BDI RESULTS: 1) There was statistically significant difference in prevalence on pre-military factor with regard to age at recruit(p<0.05) 2) PTSD on military factor was closely correlated with CES score(p<0.05) 3) There was statistically significant difference in PTSD on post-military factor with regard to occupation(p<0.05) 4) Scores of Mississippi scale, and BDI in PTSD were higher than those in control subjects(p<0.05, p<0.05) CONCLUSION: This results suggest that the likehood of developing PTSD in veterans depends on pre-military and post-military factors in addition to features of the trauma itself. Age of entry into the military, CES score, and occupation had statistically significant relationships with PTSD.

Bone marrow transplantation has become an accepted treatment for malignancy(particulary leukemia and lymphoma), aplastic anemia, and certain inborn errors of metabolism. In addition to the problem of severe, prolonged myelosuppression, bone marrow transplantation is associated with several unusual complications. Among the complications such as GVHD, graft rejection, interstitial pneumonia and veno-occlusive disease, involvement of the gastrointestinal tract by GVHD is associated with high graft failure and mortality. Intestinal GVHD is usually manifest clinically as voluminous secretory diarrhea accompanied by abdominal cramping, ileus, nutritional depletion, and, at times, hemorrhage. We experienced a case of severe intestinal GVHD after allogeneic marrow transplantation for treatment of severe aplastic anemia. He received bone marrow from his elder sister, HLA-matched multiparous woman and suffered from large amount of watery diarrhea with skin rash 34 days after transplantation. 1n spite of prednisolone therapy the symptom was progressed. After sigmoidoscopic mucosal biopsy, intestinal GVHD was confirmed and we tried methylprednisolone pulse therapy. Skin lesion was improved but the amount of diarrhea was increased with intermittent abdominal cramping. We tried ALG(anti-lymphocyte globulin) and conservative management but the patient did not respond the therapy. He succumbed to pneumonia and acute respiratory insufficiency complicated with GVHD, 70days after transplantation.

The majority of cystic lesions of the pancreas are psudocysts and a small fraction neoplastic. Failure to recognize the true nature of neoplastic cyst will lead to an incorrct treatment strategy. Ultrasonography, computerized tomography and angiography were used to distingish these lesions, but diagnostic value of ERCP is in controversy. To evaluate the diagnostic value of ERCP in cystic lesions of the pancreas, we analysed 33 cases of pancreatic cystic lesions (pseudocyst 18 cases, retention cyst 3 cases and cystic, neoplasm l2 cases) between Apr. 1985 and June 1993. In 18 cases of pseudocysts, ERP findings were communication with cyst in 8 cases (44.4%), chronic pancreatitis in 8 cases (44.4%), obstruction in 4 cases (22.2%) and displscement of pancreatic duct in 2 cases (11.1%), and ERC findings, which were perfomed in 8 cases, showed cholangitis in 3 cases (37.5%), CBD stone in 2 cases (25%), mass effect in 1 case (12.5%) and normal in 2 cases (25%). There was no communication with the cyst and pancreatic duct, except two mucinous ductal ectasia, in 12 cases of cystic neoplasms, and the other findings were displacement of pancreatic duct in 4 cases (33.3%), obstruction in 2 cases (16.7%) and normal in 4 cases (33.3%). ERC findings of cystic neoplasm were almost normal (85.7%) except 1 case of cholangitis. In conclusion, ERCP findings of pseudocysts were communication with pancreatic duct, chronic pancreatitis and biliary tract abnormality. In contrast, ERCP findings of cystic neoplasms were displacement or obstruction of pancreatic duct without communication and chronic pancreatitis, and biliary tract abnormality were rare.

Peliosis hepatis is characterized by the presence in the liver of blood-filled cavities, which may or may not be lined with sinusoidal cells. The individual cysts or cavities usually do not exceed several centimeters in diameter. The cysts are typically continuous with adjacent, more normal sinusoids, and they sometimes can be seen in continuity with hepatic venous tributaries. The lesion is usually diagnosed by gross or microscopic examination. When suspected, it can be diagnosed by percutaneous liver biopsy. In the past, peliosis hepatis is primarily associated with wasting diseases, such as tuberculosis, malignancy, and chronic suppurative infection. However, recently peliosis hepatis is seen most commonly in association with the administration of anabolic steroids or HIV infection. We report a case of peliosis hepatis that is diagnosed by peritoneoscopic live biopsy and not associated with known disease.

Measurement of Central venous pressure is very helpful to assess, the circulating blood volume, venous tone and preload of right ventricle. To obtain an accurate CVP, the correct placement of a CVP catheter is mandatory, There are many means of identifing the correct placement of a CVP catheter which was inserted through the internal jugular vein, subclavian vein and other veins. Authors have chosen the method of intracardiac EKG, which was very easy and useful clinically. The placement of a CVP catheter by intracardiac EKG using modified Lead II was verified by postoperative chest X-ray.

STATEMENT OF PROBLEM: Unlike screw-retention type, fixture-abutment retention in Locking taper connection depends on frictional force so it has possibility of abutment to sink. PURPOSE: In this study, Bicon(R) Implant System, one of the conical internal connection implant system, was used with applying loading force to the abutments connected to the fixture. Then the amount of sinking was measured. MATERIAL AND METHODS: 10 Bicon(R) implant fixtures were used. First, the abutment was connected to the fixture with finger force. Then it was tapped with a mallet for 3 times and loads of 20 kg corresponding to masticatory force using loading application instrument were applied successively. The abutment state, slightly connected to the fixture without pressure was considered as a reference length, and every new abutment length was measured after each load's step was added. The amount of abutment sinking (mm) was gained by subtracting the length of abutment-fixture under each loading condition from reference length. RESULTS: It was evident, that the amount of abutment sinking in Bicon(R) Implant System increased as loads were added. When loads of 20 kg were applied more than 5 - 7 times, sinking stopped at 0.45 +/- 0.09 mm. CONCLUSION: Even though locking taper connection type implant shows good adaption to occlusal force, it has potential for abutment sinking as loads are given. When locking taper connection type implant is used, satisfactory loads are recommended for precise abutment location.
