Since Combes' first description of hepatitis B virus associated membranous glomerulonephritis, many reports have shown a strong association of hepatitis B virus infection with various types of nephropathies, especially membranous glomerulonephritis and membranoproliferative glomerulonephritis. Recently, the authors experienced a case of membranoproliferative glomerulonephritis, type I in a 16-year-old male patient with persistent HBs and HBe antigenemia. One year prior to admission the patient was told of hepatitis at routine check, but he remained asymptomatic throughout. He was admitted to our hospital with chief complaints of proteinuria and microscopic hematuria found on routine urinalysis. Liver and kidney biopsy revealed chronic persistent hepatitis and membranoproliferative glomerulonephritis type I, respectively. We report a case of hepatitis B virus associated nephropathy with review of the literatures. Considering the endemic nature of hepatitis B virus infection in Korea, the incidence of hepatitis B virus associated nephropathy would be proportionally high in comparison with those of other countries. So, the importance of this entity merits special consideration in our country. Further study concerning pathogenesis, epidemiology, and treatment may be needed.

Empyema thoracis following pneumonia, intra-abdominal pathology, trauma, and surgical procedure continues to be a source of major morbidity and mortality. Thirty seven adult and eleven pediatric patients with empyema thoracis were treated at the University of Yeungnam Medical Center from May 1983 to November 1986. Age distribution ranged from 6 months to 72 years and showed a double-peaked curve with the highest incidence between 36 and 65 years and below 15 years of age. There were male predominance in patients above 16 years of age. The most common predisposing factors was impaired consciousness due to either alcoholism or head injury. The causes of empyema were as follows: pneumonia 64.6%, ling abscess 6.4%, intraabdominal pathology 6.4%, and surgical procedure 6.4%. The cardinal symptoms were fever, cough, chest pain, dyspnea, sputum, weight loss, anorexia, and night sweat in orders. Culture of empyema fluid were positive in 50% of patients. The isolated organisms were Gram-negative bacilli 33.3%, staphylococcus aureus 25%, and streptococcus 25%. The patients received antibiotics in conjunction with various invasive procedures: chest tube drainage 77.1%, decortications 6.3%, and repeated thoracentesis 10.3%. There were 4 deaths, 1 child and 3 adults, with an overall mortality of 8.3%.

Upper gastrointestinal(UGI) bleeding was critical disease that was commonly found in emergency department and needed more early diagnosis and rapid treatment for decreasing mortality and morbidity. It's causes and frequencies here affected by many factors, but the majorities were caused by peptic ulcers and esophageal-gastric varices. With development of economy and medical services, new drugs and endoscopic interventions, the treatment of patients with UGI bleeding was more improved. So I would like to evaluate the change of causes and frequencies of UGI bleeding and the associated clinical findings. A total of 1,546 patients presented with UGI bleeding in emergency department of Yeungnam university hospital during the five years from Jan. 1991 to Dec. 1995 were clinically reviewed by charts and compared with previous seven years report from Jan. 1984 to Dec. 1990 in the same hospital. The ratio of male to female was 6.1:1 and slightly increased in comparison with previous seven years. The incidences in 6th and 5th decades were highest(54.4%) as like as previous seven years. Age distribution of duodenal ulcer bleeding, Mallory-Weiss tear and acute gastric mucosal lesion were developed in lower decades than the others. The causes of UGI bleeding were caused by esophageal varix(45.4%), peptic ulcer(38.8%), Mallory-Weiss tear(4.3%), gastric cancer(3.8%), others(3.1%), acute gastric mucosal lesion(2.7%), undetermined causes(1.8%) in defending order of frequencies. The proportion of esophageal varices was increased from 36.6% to 45.4%, but that of peptic ulcer was relatively decreased from 47.6% to 38.8%. And the annual distribution of varices was increased, however the annual distribution of peptic ulcers was increased. Although the ranking of annual distribution of gastric ulcers and duodenal ulcers were not changed compared to previous study and the frequency of gastric ulcers was increased since 1992, but additional follow-up was needed. Seasonal variations were found that upper gastrointestinal bleeding was increased in fall and peptic ulcer bleeding was increased significantly in summer and fall, however, varix bleeding was less frequent in summer time as like as previous seven years. Emergency endoscopic examination was performed within 6 hours far 54.5%, 24 hours for 90.8% and this reacts were to be like previous results, 57.5% and 90.7% respectively. Findings of emergency endoscopic examination were active bleeding focus(21.2%), blood clot(7.9%), exposed vessels(13.3%), flat blood spot(6.4%) and lesion without evidence of bleeding(51.3%). Endoscopic findings of active bleeding were easily seton when examination was perfomed within 24 hours. Blood transfusion was performed in 67.3% with average 2.1 units. When the causes of bleeding were due to varix and marginal ulcer, more amounts of blood were transfused than the others. In previous seven years, blood transfusions were performed in 71.2% with average 5 units and more amounts of blood were transfused in gastric cancer and varix bleeding.

OBJECTIVES: Hemodynamic measurements of chronic portal hypertension were done to study the mechanisms that maintain high portal pressure despite well developed collateral circulations. METHODS: A prehepatic portal hypertensive rat model was produced by partial portal vein ligation. Cardiac output, organ blood flow and porto-systemic shunt were measured by radioisotope labeled microsphere methods, and vascular resistance was calculated by standard equation. RESULTS: There was a significant reduction in the weight of the liver and increase in the weight of the spleen in the portal stenotic rats. Porto-systemic shunting, representing development of the collateral circulations, was 96.7+/-0.6% in the portal stenosis group compared with 0.9+/-0.2% in the control group (p<0.01). Portal pressure was significantly increased in the portal stenosis group compared with the control group(12.8+/-1.4 vs. 6.5+/-0.6mmHg; p<0.01). Mean arterial pressure was significantly decreased in portal stenosis group compared with control group(101.4+/-2.5 vs, 129.9+/-3.9mmHg; p<0.01). In the portal stenosis group, cardiac output(135.7+/-8.0 vs. 111.0+/-4.2ml/min; p<0.01) and splanchnic organ blood flow (28.97+/-2.03 vs. 17.90+/-1.27ml/min, p<0.01) were significantly increased, with concomitant decrease in total peripheral vascular resistance(58.0+/-3.3 vs. 88.2+/-4.8 dyne sec/cm5 X 105; p<0.01) and splanchnic vascular resistance(2.54+/-0.20 vs. 5.47+/-0.33 dyne sec/cm5 X 105; p<0.01), However, the portal venous resistance was not significantly different in both groups of rats (3.57+/-0.31 vs. 3.03+/-0.38 dyne sec/cm5 X 105; p>0.05). CONCLUSION: The hemodynamic results of this study indicate that hyperdynamic status of systemic and splanchnic circulation was present in chronic portal hypertension and that the primary factor contributing to the persistently elevated portal venous pressure was the markedly increased portal venous inflow.

Plummer-Vinson syndrome is a clinical entity characterized by dysphagia, iron deficiency anemia, cheilosis, glossitis, and cervical esophageal web, especially in middle aged women. Recently, the authors experienced a case of Plummer-Vinson syndrome. A 53-year-old female was admitted due to intermittent solid food dysphagia for 18 months. She had a 2 years history of iron deficiency anemia. On admission glossitis, fissures at the angle of the mouth, spoon nails, and iron deficiency anemia were noted. Esophagogram and esophagoscopic examination revealed thin walled concentric web at upper esophagus. Esophageal web was succefully teared by endoscopic balloon dilatation with subseguant improvement of dysphagia. Skin manifestations as well as anemia were markedly improved after oral iron replacement therapy.
