BACKGROUND/AIMS: Chronic hepatitis C virus (HCV) infection is often associated with extrahepatic autoimmune disease, and autoantibodies such as anti-nuclear antibody (ANA) or anti-smooth muscle antibody (ASA). The presence of autoantibodies may make discrimination between chronic hepatitis C with autoimmune features and type 1 autoimmune hepatitis difficult. We studied the prevalence of autoantibodies in patients with chronic HCV infection and their clinical significance. MATERIALS AND METHODS: ANA, ASA, anti-mitochondrial antibody (AMA), anti-microsomal antibody (AmA), rheumatoid factor (RF), anti-cardiolipin antibody (aCL) and lupus anti-coagulant (LA) were tested in 116 patients (80 chronic hepatitis C, 36 liver cirrhosis). Genotypes of HCV were determined in 25 patients by INNO LiPA. RESULTS: The overall prevalence of autoantibody was 65.5%. The most common autoantibody was aCL (34.5%), followed by ANA (25%), RF (18%), LA (15.5%), ASA (6.9%), anti-microsomal antibody (6%) and AMA (1%). The positive rate of either ANA or ASA was 30.2%, but both were positive in 1.7% only. There was no difference in the demographic features, biochemistry, HCV genotypes and disease status between autoantibody-positive and autoantibody-negative patients. CONCLUSIONS: Autoantibodies were commonly found in patients with chronic HCV infection. But, the presence of autoantibodies may be a non-specific finding in chronic hepatitis C infection without clinical significance.

Hepatocellular carcinoma (HCC) is one of the most frequent and malignant diseases worldwide. Epidemiological studies have clearly demonstrated that chronic hepatitis B virus (HBV) infection is a major etiological factor in the development of HCC. The pathogenesis of HBV-associated HCC has been studied extensively, and the molecular changes associated with malignant transformation have been identified. The predominant carcinogenic mechanisms of HBV-associated HCC are chronic inflammation and the effects of cytokines in the development of fibrosis and liver cell proliferation. An important role is also played by the integration of HBV DNA into host cellular DNA, which disrupts or promotes the expression of cellular genes that are important in cell growth and differentiation. Especially, HBx protein is a transactivating protein that promotes cell growth, survival, and the development of HCC. Continued investigation of the mechanisms underlying hepatocarcinogenesis will refine our current understanding of the molecular and cellular basis for neoplastic transformation in the liver. Prevention of HBV infections and effective treatments for chronic hepatitis B are still needed for the global control of HBV-associated HCC. This review summarizes the current knowledge on the mechanisms involved in HBV-associated hepatocarcinogenesis.

We investigated whether symptom-free period(mean response time) could be prolonged when diltiazem, one of the calcium-channel blocker, as a adjuvant was administered with botulinum toxin in blepharospasm and hemifacial spasm. The patients were 10 blepharospasms and 20 hemifacial spasms who had been treating with botulinum toxin injection in our hospital. When they received only botulinum toxin for treatment of blepharospasm and hemifacial spasm, their mean response times were 126.94 +/- 42.74 and 167.32 +/- 52.90 days, respectively. After start combination therapy of diltiazembotulinum toxin, mean response times were prolonged to 163.83 +/- 53.07 (p=0.0446) in patients with blepharospasm, on the other hand, 154.21 +/- 43.36(p=0.2156) days in patients with hemifacial spasm. This study suggests that a combination treatment of diltiazem and toxin may be effective especially when the mean response time is decreased due to antibody production and the local complications are possibly expected in some patients. Present study is meaningful in that it provides a new treatment modality for blepharospasm and hemifacial spasm.

BACKGROUND: The cardiac troponin I (cTnI), one of the subunits of the troponin regulatory complex, binds to actin and inhibits interactions between actin and myosin. cTnI is highly sensitive and specific marker for myocardial injury and is useful in diagnosis and detection of reperfusion in acute myocardial infarction (AMI). In this study, we measured the serum concentration of cTnI according to serial time after chest pain in patients with AMI and compared serum concentration of cTnI with CK-MB and echocardiographic data to evaluate the significance of measuring serum concentration of cTnI in AMI. SUBJECTS AND METHODS: The study was carried out on 16 patients with first attack of AMI within 6 hours of chest pain. All patients were performed thrombolytic therapy and reperfusion was confirmed by coronary angiography. Blood samples for measuring of CK-MB and cTnI were collected at 4-h intervals during the first 24 h, 12-h intervals until 48 h, and 24-h intervals until fourth days after hospitalization. Echocardiography were performed before thrombolytic therapy in all patients. RESULTS: 1) The mean age of subjects was 63.6+/-11.5 years (range:44 - 84 years) and 11 patients were men and 5 patients were women. The site of infarction was anterior in 11 patients and inferior in 5 patients. 2) The peak concentrations of CK-MB and cTnI were reached from 4-h to 12-h after admission in all patients (7.3+/-2.6-h, and 9.0+/-3.1-h, respectively), but there was no significant difference in peak time. 3) Serum concentration of CK-MB was normalized at 72-h after admission, but cTnI was remained in increased state until 96-h after admission. The numbers of the patients with above cutoff value of CK-MB and cTnI at different time after admission were significantly different after 72-h (p<0.05). 4) The peak cTnI and sigma cTnI level were significantly correlated with peak CK-MB and sigma CK-MB level, respectively (r 2 =0.7955, p<0.0001 and r 2 =0.6378, p=0.0002, respectively). 5) The ejection fraction was not correlated with peak cTnI concentration (r 2 =0.0948, p=0.2461) and sigma cTnI (r 2 =0.1867, p=0.0946). 6) The wall motion score index was not correlated with peak cTnI concentration (r 2 =0.2135, p=0.0716), but significantly correlated with sigma cTnI (r 2 =0.2540, p=0.0465). CONCLUSION: The serum concentration of cTnI was useful in late diagnosis of AMI and cTnI release in patients with AMI was correlated with myocardial infarct size.

BACKGROUND/AIMS: Spontaneous bacterial peritonitis (SBP) is a major problem associated with liver cirrhosis which has high mortality. Increased production of inflammatory mediators, such as tumor necrosis factor-a (TNF-a) and interleukin- (IL-) may be associated with development of renal impairment, one of the most important prognostic parameters in SBP. The aim of this study is to investigate the changes of these cytokines in ascitic fluid and plasma in patients with SBP and the relationship between these cytokines and development of renal impairment. METHODS: Forty patients with liver cirrhosis and ascites were studied 21 with SBP and 19 with sterile ascites. TNF-a and IL- levels in ascitic fluid and plasma were determined by ELISA at the time of diagnosis in both groups and 48 hours after antibiotics treatment in SBP patients. RESULTS: TNF-and IL- levels in ascitic fluid and plasma were significantly higher in patients with SBP than those without SBP (ascitic fluid TNF-a: 2.5+/-0.5 vs. 1.6+/-0.2; plasma TNF-a: 2.3+/-0.5 vs. 1.5+/-0.2; ascitic fluid IL-: 3.8+/-0.5 vs. 3.0+/-0.4; plasma IL-: 3.4+/-0.5 vs. 2.3+/-0.3, log pg/mL)(p<0.001). In patients with SBP, levels of TNF-a and IL- in ascitic fluid and plasma decreased 48 hours after antibiotics treatment. Eleven patients with SBP (11/21, 52%) developed renal impairment. Patients with renal impairment had significantly higher ascitic fluid and plasma TNF-a levels than those without renal impairment (median 2.5 vs. 2.1 for ascitic fluid, p=0.006; median 2.4 vs. 2.0, log pg/mL for plasma, p=0.04). Although four out of eleven (36%) patients who developed renal impairment died during hospitalization, all the patients without renal impairment survived (p=0.09). CONCLUSION: Our results suggest that the levels of TNF-a and IL- in ascitic fluid and plasma are increased in SBP and elevated levels of TNF-a in ascitic fluid and plasma may be associated with development of renal impairment, thus indicating poor prognosis in patients with SBP.

Congenital long QT syndrome (LQTS) is an inherited disease characterized by prolonged QT intervals and polymorphic ventricular tachycardia. The clinical manifestations vary from sudden cardiac death by ventricular arrhythmia to asymptom throughout life. In 1957, Jervell and Lange-Nielsen reported a syndrome of congen-ital sensory deafness associated with a prolonged QT interval in four children. The affected children had multiple syncopal episodes, and three died suddenly. The mode of inheritance is autosomal recessive. Affected persons are susceptible to recurrent syncope, and they have a high incidence of sudden death and short life expectancy. We report a case and review the literature on long QT syndrome diagnosed in a 30-year-old female with a history of convulsion and loss of consciousness during delivery.

BACKGROUND: The electrocardiogram may provide valuable information regarding the identity of the culprit coronary artery and the location of obstructing lesion within the artery, which may be of guidance in selecting the therapeutic modality. Previous studies have concluded that changes in lateral leads (I, aVL, V5, V6) are predictive of left circumflex coronary artery obstruction in inferior wall acute myocardial infarction. Elect-rocardiographic criteria for determining the location of the obstructing lesion, however, have not been well established. The purpose of this study is to investigate the patterns of ST segment depression in lateral leads in inferior wall acute myocardial infarction and the obstruction site of culprit artery according to ST segment depression in lateral leads. METHODS: We examined 78 patients with inferior wall acute myocardial infarction analizing their electrocardiogram and coronary angiography which performed during acute hospitalization. RESULTS: Of the fifty-five patients in which the culprit artery could be determined, 1)in 41 the culprit artery was the right coronary artery (19 proximal to the right ventricular branch and 22 distal), and in 14 the left circumflex coronary artery (7 proximal to the first obtuse marginal branch or involving a high first obtuse marginal branch, and 7 with distal obstruction). 2)Significant ST depression (ST< or =1 mm) in leads I and aVL was more common in right coronary artery obstruction (p<0.05 and p=0.01 respectively) than left circumflex artery. 3)It was difficult to define the location of obstruction with ST segment change of lateral precordial leads (V5, V6). CONCLUSIONS: In acute inferior wall myocardial infarction, ST segment depression in lateral limb leads (I, aVL) can be indicative of the right coronary artery obstruction and the ST segment depression pattern in lateral precordial leads was not indicative of the site of obstruction.

When examining in the patients with epiphora, it is common to evaluate only the insufficiency or obstruction of lacrimal pathway by irrigation or dacryocystography and to over look the conjunctival conditions near the punctum in most cases. Authors found marked redundancy of conjunctival tissue around the punctal area in 8 patients(12 eyes) who complained of epiphora. They have neither lacrimal pathway insufficiency and obstruction, nor facial palsy or lid laxity that can impass the lacrimal pump action, and also no anatomical anomaly of the puncta. In fluorescein dye dissappearence test of these patients, the clearance of dye was markedly delayed on the lesion site(Grade 3 to 4). Epiphora was dramatically improved after simple resection of redundant conjunctiva under surgical microscope. The Hematoxylin-Eosin and Toluidine-Blue staining of resected conjunctiva revealed infiltration of many inflammatory cells and increase of metachromatic cells in the conjunctival stroma.
