Acute hepatitis E is an endemic disease, commonly reported in Indian subcontinent, China, Africa, Central America, and so forth. It is a self-limiting disease like other acute hepatitis except in pregnant patient. Although sporadic hepatitis E is noted all over the world, most of them are associated with travel history to HEV-endemic area. In Korea, Hepatitis E is rarely reported. Moreover, sporadic acute hepatitis E without travel history to HEV-endemic area is very rare. We experienced three sporadic cases of acute hepatitis E, without travel history. All of them presented acute hepatitis symptoms, elevated aminotransferase, and positive IgM HEV Ab. Symptoms and aminotransferase levels were normalized during hospitalization and IgM HEV Ab converted negative after 4-8 months. We report three sporadic cases of onset-acute hepatitis E without travel history to HEV-endemic area.

BACKGROUND: Minimal-flow anesthesia can meet the demands of a modern society that is more sensitive to environmental protection and economic burdens. This study compared the safety and efficacy of minimal-flow desflurane anesthesia with conventional high-flow desflurane anesthesia for prolonged laparoscopic surgery. METHODS: Forty-six male patients (ASA physical status II or III) undergoing laparoscopic urologic surgery for more than 6 hours were randomly divided into two groups: the high-flow (HF) group and the minimal-flow (MF) group. The HF group was continuously administered a fresh gas flow of 4 L/min. In the MF group, a fresh gas flow of 4 L/min was administered for the first 20 minutes and was thereafter lowered to 0.5 L/min. Inspiratory and expiratory desflurane concentrations, respiratory variables, and hemodynamic variables were continuously monitored during administration of anesthesia. Measurements of carboxyhemoglobin (COHb) concentration and arterial blood gas analysis were performed every 2 hours during anesthesia. Serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN) and creatinine were measured on the first and second day after the surgery. RESULTS: Demographic data and duration of anesthesia were not different between the two groups. Significant differences were not observed between the two groups in terms of hemodynamic variables, respiratory variables, and inspiratory and expiratory desflurane concentrations. Inspiratory O2 concentration was maintained lower in the MF group than in the HF group (43-53% vs. 53-59%; P < 0.05). Compared with the HF group, COHb concentrations was higher (P < 0.05), but not increased from the baseline value in the MF group. Serum AST, ALT, BUN, and creatinine were not significantly different between the two groups. CONCLUSIONS: In prolonged laparoscopic surgery, no significant differences were found in safety and efficacy between minimal-flow and high-flow desflurane anesthesia.

PURPOSE: Recently, randomized controlled trials have reported that conservative therapy can be a treatment option in patients with noncomplicated appendicitis. However, preoperative diagnosis of noncomplicated appendicitis is difficult. In this study, we determined predictive factors to distinguish patients with noncomplicated appendicitis from those with complicated appendicitis. METHODS: A total of 351 patients who underwent surgical treatment for acute appendicitis from January 2011 to December 2012 were included in this study. We classified patients into noncomplicated or complicated appendicitis groups based on the findings of abdominal computed tomography and pathology. We performed a retrospective analysis to find factors that could be used to discriminate between noncomplicated and complicated appendicitis. RESULTS: The mean age of the patients in the complicated appendicitis group (54.5 years) was higher than that of the patients in the noncomplicated appendicitis group (40.2 years) (P < 0.001), but the male-to-female ratios were similar. In the univariate analysis, the appendicocecal junction's diameter, appendiceal maximal diameter, appendiceal wall enhancement, periappendiceal fat infiltration, ascites, abscesses, neutrophil proportion, C-reactive protein (CRP), aspartate aminotransferase, and total bilirubin were statistically significant factors. However, in the multivariate analysis, the appendiceal maximal diameter (P = 0.018; odds ratio [OR], 1.129), periappendiceal fat infiltration (P = 0.025; OR, 5.778), ascites (P = 0.038; OR, 2.902), and CRP (P < 0.001; OR, 1.368) were statistically significant. CONCLUSION: Several factors can be used to distinguish between noncomplicated and complicated appendicitis. Using these factors, we could more accurately distinguish patients with noncomplicated appendicitis from those with complicated appendicitis.

BACKGROUNDAs one of the intercellular adhesion molecules, CD58 plays important roles in promotion of the adhesion between T cells and target cells, hyperplasia, activation of T cells and natural killer cells, and balance between Th1 and Th2. We studied the relationship between the levels of CD58 expression in peripheral blood mononuclear cells (PBMCs) and severity of HBV infection.

METHODSThe levels of CD58 mRNA in PBMCs were detected using quantitative reverse transcription PCR. The percentage of CD58 positive cells was detected by flow cytometry in patients and healthy controls.

RESULTSThe levels of CD58 mRNA and the percentage of CD58 positive cells in patients infected with HBV were significantly higher than that in the control. Based on severity of HBV infection, the patients were classified into four groups. The expression of CD58 increased significantly in an order from mild chronic, moderate chronic, severe chronic to severe hepatitis groups. The levels of CD58 mRNA and the percentage of CD58 positive cells in PBMCs from patients with HBV infection were both positively correlated with serum levels of ALT and AST.

CONCLUSIONThe level of CD58 expression is related with the severity of HBV infection and the degree of liver damage.

OBJECTIVETo investigate the diagnostic values of prealbumin (PAB) and retinol-binding protein (RBP) for liver damage caused by mild or severe asphyxia.

METHODSA retrospective analysis was performed on 185 neonates (including 84 premature infants and 101 full-term infants) with asphyxia. Based on the Apgar score, they were divided into two groups: mild asphyxia group (n=150) and severe asphyxia group (n=35). The levels of PAB, RBP, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were measured and compared. Their diagnostic values for liver damage were evaluated by ROC curve analysis.

RESULTSThe premature infants in the severe asphyxia group had significantly higher AST level and significantly lower levels of PAB and RBP than those in the mild asphyxia group (P<0.05). The full-term infants in the severe asphyxia group had a significantly lower PAB level than those in the mild asphyxia group (P<0.05). After treatment, the PAB level was significantly improved in the premature infants in the severe asphyxia group and in the full-term infants in both mild and severe asphyxia group (P<0.05). The full-term infants in the mild asphyxia groups also showed a significant improvement in AST level (P<0.05). The ROC curve analysis showed that PAB had a good sensitivity and specificity for identifying liver damage caused by mild or severe asphyxia in full-term and preterm infants.

CONCLUSIONSPAB can be used as an indicator of liver damage caused by asphyxia in neonates, and can be used to assess the degree of asphyxia.

PURPOSE: In order to provide effective hospice care, adequate length of survival (LOS) in hospice is necessary. However the reported average LOS is much shorter. Analysis of LOS in hospice has not been reported from Korea. We evaluated the duration of LOS and the factors associated with LOS at our hospice center. MATERIALS AND METHODS: We retrospectively examined 446 patients who were admitted to our hospice unit between January 2010 and December 2012. We performed univariate and multivariate analysis for analysis of factors associated with LOS. RESULTS: The median LOS was 9.5 days (range, 1 to 186 days). The LOS of 389 patients (86.8%) was< 1 month. At the time of admission to hospice, 112 patients (25.2%) were completely bedridden, 110 patients (24.8%) had mouth care only without intake, and 134 patients (30.1%) had decreased consciousness, from confusion to coma. The median time interval between the day of the last anticancer treatment and the day of hospice admission was 75 days. By analysis of the results of multivariate analysis, decreased intake and laboratory results showing increased total white blood cell (WBC), decreased platelet count, increased serum creatinine, increased aspartate aminotransferase (AST), alanine aminotransferase (ALT), and lactate dehydrogenase (LDH) level were poor prognostic factors for survival in hospice. CONCLUSION: Before hospice admission, careful evaluation of the patient's performance, particularly the oral intake, and total WBC, platelet, creatinine, AST, ALT, and LDH level is essential, because these were strong predictors of shorter LOS. In the future, conduct of prospective controlled studies is warranted in order to confirm the relationship between potential prognostic factors and LOS in hospice.

OBJECTIVETo analyse the factors which influence the four serum fibrosis markers hyaluronic acid (HA), type III procollagen (PCIII), laminin (LN) and type IV collagen (CIV).

METHODSThe levels of serum HA, PCIII, LN and CIV were measured by RIA in 141 patients with chronic hepatitis B (CHB), then the patients were divided into two groups according to the serum fibrosis markers, namely consistent group and inconsistent group. the liver biopsy materials were examined pathomorphologically and liver function was detected by automatic biochemistry analyzer, The interior diameters of the portal vein, the spleen vein and the thickness of the spleen were also measured with ultrasonography.

RESULTS16 patients (14.16%) whose serum fibrosis markers were inconsistent with histological stage of liver fibrosis were found. Their serum fibrosis markers were not correlated with staging of liver fibrosis (P>0.05), but were positively correlated with inflammation grade (x(2)=12.07, P<0.05), at same time, the serum levels of alanine aminotransferase (ALT), aspartate aminotransferase(AST), gamma-glutamyltransferase (GGT) and globulin (GLB) decreased obviously, from 89.28 U/L +/- 64.25 U/L to 49.31 U/L +/- 26.75 U/L (t=2.45, P<0.05), 66.10 U/L +/- 42.30 U/L to 40.83 U/L +/- 22.40 U/L (t=2.33, P<0.05), 86.26 U/L +/- 70.36 U/L to 48.99 U/L +/- 29.96 U/L (t=2.08, P<0.05) and 32.13 g/L +/- 5.18 g/L to 28.05 g/L +/- 3.47 g/L (t=3.03, P<0.01) respectively. And the level of albumin (ALB) and the ratio of albumin and globulin (A/G) increased evidently, from 42.34 g/L +/- 4.81 g/L to 46.19 g/L +/- 3.61 g/L (t=3.06, P<0.01) and 1.35 +/- 0.28 to 1.63 +/- 0.26 (t=3.70, P<0.01). But the serum level of alkaline phosphatase (ALP), total bilirubin (TBil), total protein (TP), the width of main portal vein, the width of splenic vein and the thickness of the spleen did not change clearly (P>0.05).

CONCLUSIONAs diagnostic markers, serum fibrosis markers as well as inflammation grade and liver function should be taken into account.

Increasing evidence suggests an association between elevated serum aminotransferase level and the metabolic syndrome. However, the significance of relatively low levels of aminotransferase in relation to the metabolic syndrome has not been fully investigated in the general population. We investigated the association between serum amiontransferase level and the metabolic syndrome using data from a nationwide survey in Korea. We measured serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels and metabolic conditions among 9771 participants aged 20 or more in the 1998 and 2001 Korean National Health and Nutrition Examination Surveys. Metabolic syndrome was defined according to NCEP-ATP III criteria with a modified waist circumference cutoff (men > 90cm; women > 80cm). Serum aminotransferase level, even within normal range, was associated with the metabolic syndrome independent of age, body mass index, waist circumference, smoking, and alcohol intake. Compared with the lowest level (<20IU/L), the adjusted odds ratios (95% CI) for an AST level of 20-29, 30-39, 40-49 and > or = 50IU/L were 1.10 (0.85-1.42), 1.37 (1.02-1.83), 1.62 (1.08-2.43), and 2.25 (1.47-3.44) in men, and 1.18 (0.99-1.41), 1.43 (1.29-1.83), 1.71 (1.09-2.68), and 2.14 (1.20-3.80) in women, respectively. Corresponding odds ratios for ALT levels were 1.27 (0.99-1.63), 1.69 (1.28-2.23), 2.17 (1.58-2.99), and 2.65 (1.96-3.58) in men, and 1.44 (1.22-1.70), 1.65 (1.26-2.15), 2.94 (1.93-4.47), and 2.25 (1.54-3.30) in women, respectively. In conclusion, elevated serum aminotransferase levels, even in the normal to near normal range, are associated with features of the metabolic syndrome.

The purpose of this study was to evaluate and assess the compatibility of current risk scoring systems from Japan that were developed to predict intravenous immunoglobulin (IVIG) resistance in patients with Kawasaki disease (KD). The authors previously investigated another prediction model for patients with refractory KD in Korea. A retrospective study involving 350 patients with KD who were admitted between January 2014 and December 2015 was performed. Patients younger than 2 years were excluded for the propensity score matching in this study. Patients were classified into IVIG responders and IVIG resistance groups. The well-known Harada, Kobayashi, and Egami risk scores were calculated for each patient, and the proportion of high-risk patients was compared between the two groups for each risk score. Logistic regression analysis revealed that platelets, C-reactive protein (CRP) levels, and aspartate aminotransferase levels were independent predictors of IVIG resistance. Multivariate analysis suggested that platelets and CRP were risk factors. Risk-scoring systems from Japan have good specificity but low sensitivity. Among the three risk scoring systems, the Kobayashi risk score demonstrated significant differences between the IVIG resistance and IVIG responder groups in Korean patients with KD. It is very important to identify IVIG-resistant patients to protect them from ongoing coronary arterial lesion(s); therefore, early prediction and timely optimal additional treatment is of significant benefit. It would be helpful to construct a highly sensitive, exclusive scoring system for Korean patients with KD.

BACKGROUND/AIMS: To assess the usefulness of magnetization-tagged magnetic resonance imaging (MRI) in quantifying cardiac-induced liver motion and deformation in order to predict liver fibrosis. METHODS: This retrospective study included 85 patients who underwent liver MRI including magnetization-tagged sequences from April 2010 to August 2010. Tagged images were acquired in three coronal and three sagittal planes encompassing both the liver and heart. A Gabor filter bank was used to measure the maximum value of displacement (MaxDisp) and the maximum and minimum values of principal strains (MaxP1 and MinP2, respectively). Patients were divided into three groups (no fibrosis, mild-to-moderate fibrosis, and significant fibrosis) based on their aspartate-aminotransferase-to-platelet ratio index (APRI) score. Group comparisons were made using ANOVA tests. RESULTS: The patients were divided into three groups according to APRI scores: no fibrosis (≤0.5; n=41), moderate fibrosis (0.5-1.5; n=23), and significant fibrosis (>1.5; n=21). The values of MaxDisp were 2.9±0.9 (mean±SD), 2.3±0.7, and 2.1±0.6 in the no fibrosis, moderate fibrosis, and significant fibrosis groups, respectively (P<0.001); the corresponding values of MaxP1 were 0.05±0.2, 0.04±0.02, and 0.03±0.01, respectively (P=0.002), while those of MinP2 were -0.07±0.02, -0.05±0.02, and -0.04±0.01, respectively (P<0.001). CONCLUSIONS: Tagged MRI to quantify cardiac-induced liver motion can be easily incorporated in routine liver MRI and may represent a helpful complementary tool in the diagnosis of early liver fibrosis.
