Multiple biliary papillomatosis involves an epithelial field change of the intrahepatic and extrahepatic portions of the biliary tree. Pathologically it is benign, occasionally with dysplasia, but the clinical behavior is regarded as having a low-grade malignant potential. Such malignancy is rare but the prognosis is poor if it is impossible to remove the tumor completely. Here, we report one case of multiple biliary papillomatosis in the biliary tree.

OBJECTIVE: To assess the relationship between vaginal cytology and bone mineral density in postmenopausal women. METHODS: In 93 postmenopausal women, vaginal cytology smears were taken for maturation index, serum estradiol level and bone mineral density were also taken. the percentage of each cell type found By vaginal cytology was multiplied to its specific value:superficial cells, 1.0; intermediate cell, 0.6; parabasal cell, 0.2 and modified to maturation value. Bone mineral density was measured at lumbar spine using DEXA. RESULTS: The mean bone mineral density was 0.88+/-0.14g/cm2. Mean maturation value was 50.53+/-20.74 and it was related with age and bone mineral density. CONCLUSION: Maturation value of vaginal epithelial cell represents the influence of estrogen on bone mineral density.

Preoperative and postoperative echocardiography were performed in 33 patients with isolated ostium secondum atial septal defect(ASD), confirmed by right heart catheterization and operation at Seoul National University Hospital from November 1980 to June 1982. The ratio of right ventricular enddiastolic dimension to leftventricular enddiastolic dimension(RVED/LVED) was compared to the pattern of interventricular septum, before and after operation. In patients with persistent paradoxical septal motion during 2wks after operation, repeated echocardiograms were performed upto 9 months, postoperatively. The results obtained are as follows: 1) The ratio of RVED/LVED in patients with ASD, was 0.95+/-0.35(mean+/-standard deviation), which was significantly larger than that of 14 normal subjects(p<0.005). 2) There was statistically correlation between the ratio of pulmonary blood flow to systemic blood flow(QP/QS) and the ratio of RVED/LVED(r=0.44, p<0.025). 3) Thirty three patients were divided into 3 groups according to the pattern of intervent ricular septal motion.(Group "M": Patients with normal septal motion, Group "B": Patients with paradoxical type B septal motion, Group "A": Patients with paradoxical type A septal motion) Preoperatively, the ratio of RVED/LVED was 0.68+/-0.28 in Group "N" (N=9), and 0.88+/-0.23 in Group B (N=9) and 1.14+/-0.34 io Group "A" (N=15). In Group "A, the ratio of RVED/LVED was significantly larger than of Group "N" (p<0.005). Postoperatively, the ratio of RVED/LVED was 0.51+/-0.13 in Group "N" (n=23), and 0.68+/-0.15 in Group "B" (n=7), and 0.79+/-0.14 in Grop "A" (n=3). In Group "A" and Group "B, the ratio of RVED/LVED was significantly larger than that of Group "N" (p<0.005, p<0.01). 4) Postoperative RVED index(18.9+/-4.9) was significantly decreased, compared with preoperative RVED index(27.6+/-8.9) (p<0.005). But there was no significant change in LVED index, before and after operation. 5) Among 10 patients with persistent paradoxical septal motion, repeated echocardiograms were performed in 5 patients. Interventricular septal motion was normalized in 4 out of 5 patients. Thus the ratio of RVED/LVED has significant correlation with QP/QS and the pattern of interventricular septal motion. These results suggest the evidence that interventricular septal motion is determined by septal position at enddiastiole.

Takayasu's arteritis is an arteritis of undetermined etiology, which affects the aorta and the proximal portions of its major branches. But aortic regurgitation and coronary artery involvement were unusual manifestations in this disease. We experienced a patient of Takayasu's arteritis who represented these unusual manifestations. Aortogram revealed grade IV aortic regurgitation and proximal segment narrowing of left main coronary artery. A case of Takayasu's arteritis associated with aortic regurgitation and left main coronary artery involvement is reported with a review of literatures.

OBJECTIVES: A retrospective study was performed to clarify the change of lumbar bone mineral density(BMD) according to the duration of hormone replacement therapy(HRT) and the other factors such as age, years since menopause(YSM) and initial BMD in postmenopausal women. METHODS: From January, 1995 to December, 1998 we measured lumbar bone mineral density in 100 postmenopausal women in the department of obstetrics and gynecology, Inha University Hospital. These women had been followed for 2 years after taking HRT. We investigated whether there were any relation between the duration of HRT, age, YSM, initial BMD and change of BMD. RESULTS: Lumbar BMD was increased 2.06% after one year of HRT(p=0.0001) but there was no change of BMD at the 2nd year of HRT(p=0.847). The response to HRT was greatest in those who were oldest(r=0.209 ; p=0.039) and furthest YSM(r=0.209; p=0.039), and consequently among those who had the lowest BMD(r=0.590 ; p=0.0001). CONCLUSION: The bone mass was increased upto 2.06% at the 1st year of HRT but no more progressive increase was occurred. It suggest that intensive HRT is needed at 1st year of therapy. The risk of fracture is not decreased to that of the healthy population inspite of HRT, so the earlier therapy is necessary to prevent osteoporotic fracture despite of intervention.

Peliosis hepatis is an uncommon liver condition involving abnormal dilation of hepatic sinusoids, eventually leading to blood-filled cavities within the hepatic parenchyma. Although the pathogenesis is not understood fully, peliosis hepatis has usually been associated with the use of anabolic steroid therapy, oral contraceptives, various malignancies or tuberculosis. We report a case of 59-year-old patient with cholangiocarcinoma with peliosis hepatis. The patient was admitted for evaluation of abdominal pain and fever. Abdomen CT showed a round cytic and solid mass with peripheral duct dilatation in liver. Grossly, the spongy-like solid mass and cyst was noted. Microscopically, the solid mass was composed of tubular and solid adenocarcinoma in fibrotic stroma and a blood-filled cavity with dilated sinusoids was noted.

Gastrointestinal autonomic nerve tumors (GANT) are uncommon neoplasms of the gastrointestinal tract. The GANT is a specialized form of stromal neoplasm with the feature of myenteric plexus derivation. We report a patient with a GANT of the small intestine and liver metastasis. The patient was admitted for evaluation of hematochezia and a palpable abdominal mass. A CT of the abdomen showed an exophytic mass arising from the distal ileum and exhibiting deep ulceration and air-cavity formation, and a huge cystic mass in the right lobe of the liver. The gross appearance of a surgical specimen of the liver showed a huge cystic mass, containing liquified hemorrhagic fluid, with an irregular nodular peripheral portion. Its capsule was intact. An ileal mass, measuring 9x5 cm and arising from the submucosal layer, with deep ulceration was seen. Histological examination of the liver and the ileal mass revealed a malignant stromal tumor with neural differentiation on immunohistochemical staining.

BACKGROUND: To evaluvate the hypothesis that reperfusion injury and reperfusion arrhythmia could be caused by oxyzen free redicals and that prolonged myocardial dysfunction could be induced by oxyzen free redical. METHODS: Experimnetal model of anesthetized open chest dogs was used. Coronary artery was occluded for 60 minutes and reperfusion was performed 4 hours. In 5 dogs, superoxide dismutase and catalase were infused concomitantly 15 minutes after coronary occlusion to 15 minutes after reperfusion. In 9 dogs, 0.9% saline was infused instead of free redical scavengers. Hemodynamic parameters such as heart rate, left ventricular peak systolic pressure, end-diastolic pressure, peak positive dP/dt, and peak negative dP/dt were analysed. Infarct size was estimated by the unstained area in nitroblue tetrazolium staining and risk area was calculated from the unstained area after methylen blue infusion. Regional systolic function was observed in systolic thickening of ischemic area by echocardiogram. RESULTS: 1) Reperfusion arrhythmia occurred in 67% of control group and in 50% of drug treated group. 2) Systolic hemodynamic parameters such as peak systolic pressure, peak positive dP/dt showed no difference between control and drug-treated group. 3) Diastolic parameters such as end-diastolic pressure and peak negative dP/dt were not different in two groups. 4) Regional systolic parameter measured by systolic thickening in ischemic area improved after reperfusion and continued to be better in drug treated group than in control group. 5) Infarct size, risk area, ratio of infarct size to risk aera were not different in two groups. CONCLUSION: Superoxide dismutase and catalase showed no effect in reducing the infarct size in anesthetized open chest canine model with 60 minutes of coronary occlusion 4 hours of reperfusion. However, postischemic prolonged myocardial dysfunction tended of improve-after reperfusion in drug treated group.

Despite the high incidence of subdural block (SDB) during epidural anesthesia, the condition is unfamiliar to anesthesiologist. We experienced a case of SDB: severe hypotension, transient hemiplegia, wide extent of block and late onset and recovery from block. The case described is an examples of SDB and should remind anesthesiologist of the clinical course and treatment.

Right sided aortic arch is commonly accompanied by congenital heart disease, but abnormally originated left subvlavian artery can be acompression of trachea or esophagus by ducturs arteriosus or ligamentum arteriosus. But right sided aortic arch compressing superior vena cava has not been reported in Korea.We exerienced a case of right sided aortic arch with left subclavian artery compressing the superior vena cava, resulting in superior vena cava syndrome. So we report this case with brief review of literature.
