Sensitivity to mercury appears to be not uncommon and perhaps the commonest contact with mercury in the general population is by amalgam dental restorations. Recently, we have experienced 2 cases of mercury dermatitis following amalgam dental restorations which were confirmed by the patch test. We report our cases with the patch test results and review the literatue on previous reports.

We report 2 cases who have been diagnosed as lipodystrophia centrifugalis abdominalis juvenilis. The case 1 is l2 year-old girl. She had well-defined depression of skin on both inguinal area, lower portion of chest and both flanks which was noticed at the age of 7. The case 2 is 16 year-old boy with depressed lesions on Rt. inguinal area and abdomen which were noticed at the age of 6. Biopsy specimen showed absence of subcutaneous fat tissue in both cases.

The present study was performed to evaluate the comedogenicity of several cosmetic ingredients, vegetable oils, steroid and sulfur. The test materials were applied to one ear canal of rabbits for 6 weekdays for 2 weeks. The results were as follows: l. Among the 14 cosmetic ingredients, no comedogenicity was shown in propylene glycol and petrolatum, mild comedogencity in squalene, acetylated lanolin, polyethylene glycol, cetyl aIcohol and Tween 80. Propylene glycol, sodium lauryl sulfate and oleic acid showed moderate comedogenicity. Severe comedogenicity was observed in myristyl myristate, isopropyl myristate, butyl stearate and myristyl lactate. 2. Moderate to severe comedogenicity was shown in olive oil, sesame oil and corn oil and moderate comedogenicity in sulfur (8%) and betamethasone dipropionate (0.06%) R. Histopathologic grading were paralleled the findings of the naked eye.

BACKGROUND AND AIMS: Hepatitis C virus (HCV)-associated cirrhosis is an increasingly frequent indication for liver transplantation (LT). However, HCV recurrence is universal and this immediately occurs following LT, which endangers both the graft and patient survival. We investigated the frequency of posttransplant recurrence of HCV infection and the patient-graft survival, and we analyzed the responses to ribavirin and interferon therapy in the patients with recurrent HCV infection after living donor liver transplantation (LDLT). METHODS: We retrospectively reviewed the clinical outcomes of 39 HCV-associated cirrhosis patients who underwent LDLT at Asan Medical Center between August 1992 and June 2006. In this study, the diagnosis of recurrent HCV was made on the basis of increased transaminases and serum HCV RNA levels greater than 10 million IU/mL because protocol liver biopsy was not performed. RESULTS: HCV recurrence was seen in 26 of the 39 LDLT patients (66.7%). 86.7% of recurrence occurred within the first postoperative year. Antiviral treatment was used for all patients with recurrence of HCV. None of the 10 patients receiving ribavirin alone and 9 of 16 patients who received combination therapy with pegylated interferon alpha-2a plus ribavirin became HCV RNA negative and they remained persistently negative during the median follow-up of 24.9 months. Our data indicates that there is no significant factor influencing HCV recurrence except for the recipient's age. The 2-year patient survival for the HCV patients with HCC and those patients without HCC were 81.2% and 81.3%, respectively (P=0.85) and the 2-year graft survival rates were 81.2% and 68.2%, respectively (P=0.29). No patient died from HCV recurrence during the follow-up period. CONCLUSIONS: Combination therapy with ribavirin and interferon appears to improve the outcome of recurrent HCV infected patients after LDLT.

Hepatitis E virus is an enterically transmitted virus that causes endemic cases of acute hepatitis in many countries in Africa, and Southeast and Central Asia. Sporadic cases of acute hepatitis E also have been reported in developed countries. In non-endemic areas, most of the sporadic cases of hepatitis E are introduced from the endemic areas. Until now, only three cases of acute hepatitis E have been reported in Korea. Recently, we experienced nine cases of acute hepatitis, in which serologic studies showed positive of IgM anti-HEV. We report these as cases of acute hepatitis E. These cases suggest that HEV infection occurs sporadically in Korea and should be considered as a cause of cryptogenic acute hepatitis.

BACKGROUNDS: Living-donor liver transplantation (LDLT) has been established as an efficacious option to resolve the shortage of cadaveric donor organs for pediatric recipients. This surgical innovation has significantly reduced the pretransplantation mortality for children, but the crisis of increasing scarcity of donor organs in our hospital has led us to extend LDLT to adult recipients. However, the extension of LDLT from pediatric recipients to adult recipients has been made only with limited success largely because of the inability of a relatively small-size left-lobe graft to meet the metabolic demands of an adult recipient. It has been postulated that a left-lobe graft smaller than 40% of the recipient's standard liver volume will not result in a successful adult-to-adult LDLT in chronic parenchymal liver disease. METHODS: From February 1997 to October 1997, 10 LDLTs, using 9 extended left-lobe grafts and 1 right-lobe graft, were performed on patients with end-stage parenchymal liver diseases (9 cases of B-hepatitis-induced cirrhosis with or without an associated hepatocellular carcinoma and 1 case of alcoholic cirrhosis) at the Department of Surgery, Asan Medical Center. The ratios of the graft to the standard liver volume of the recipients were in the range of 30% to 55%. RESULTS: All grafts showed immediate function, but delayed normalization of the serum total bilirubin was demonstrated in all recipients receiving left-lobe grafts. There were no mortalities and serious complications in donors. Two recipients died of sepsis 21 days and 40 days after transplantation, and 8 recipients (80%) are alive with good liver function at a median follow-up of 5.1 months (range 2~10 months). CONCLUSIONS: The aim of this article is to report our experience with adult-to-adult LDLT shows that a graft size greater than 30% of the recipient's standard liver volume is able to meet the metabolic demands of adult recipients with chronic parenchymal liver disease and that LDLT might open a new donor pool for adult recipients when the supply of cadaveric organs is severely restricted.

The aim of this study was to investigate the efficacy of simvastatin to improved lipid profiles in hypercholesterolemic Korean patients. METHODS: From 25 hospitals in Korea, 478 hypercholesterolemic patients were enrolled from November 1996 to April 1998. The inclusion criteria was hypercholesterolemia over 240 mg/dl after diet therapy for 1 month or hypercholesterolemia over 220 mg/dl in patients with definite evidence of ischemic heart disease. Simvastatin 10mg was started and doubled up to 40mg if total cholesterol level remained higher than 200 mg/dl at monthly check. Of 478 subjects, 344 patients in whom study protocol was not violated were analyzed. RESULTS: Male to female ratio was 27:73 and 47% of the subjects were in 6th decade. Hypertension, coronary artery disease, and diabetes mellitus were present in 30, 10, and 4% of the subjects. Baseline lipid profile (mean of total cholesterol-LDL-HDL-triglyceride mg/dl) was 274-185-52-188. The dose of simvastatin for 3 months was 10/10/10mg in 61% of subjects, 10/20/20mg in 21%, 10/10/20mg in 7%, and 10/20/40mg in 12%. The change of total cholesterol level(before-4wk-8wk-12wk-withdrawal 4wk) was 274-209- 205-198-250, and the maximal reduction rate was 27%. The change of LDL-cholesterol was 185-123-116-110-159, with maximal reduction rate 39%. The change of HDL-cholesterol was 52-54-56-55-54, with maximal increase rate 9%. The change of tryglyceride was 188-161- 164-162-189, with maximal reduction rate 15%. The value before/after treatment of ApoA1, ApoB, and Lp(a) was 129/129, 138/83, and 9.3/10.7, respectively. The level of LDL-cholesterol at the end of treatment was below 100mg/dl in 36% of subjects, 100-130 in 45%, 130-160 in 16%, and over 160mg/dl in 4%. The reduction rate of LDL-cholesterol was different between subjects whose LDL decreased below 100 and those whose LDL did not decrease below 130mg/dl, which suggests the existence of the individual difference of responsiveness to simvastatin. There were only 3 subjects (0.9%) who showed increase of liver enzyme over 3 times as the upper normal limit. Conclusion: Simvastatin is effective in improving lipid profiles in hypercholesterolemic Korean patients without serious side effects.
