[Show abstract][Hide abstract] ABSTRACT: Although acute hepatitis and nephrotic syndrome are commonly reported as complications of tertiary syphilis, nephrotic syndrome concomitant with hepatitis in early-stage syphilis is rare. Here, we describe the case of a 46-year-old male who was diagnosed with acute liver dysfunction and nephrotic syndrome after presenting with general malaise, and who subsequently developed acute kidney injury. Laboratory examination showed alkaline phosphatase had a greater magnitude of elevation compared to alanine aminotransferase, suggesting the possibility of syphilitic hepatitis. The rapid plasmin regain test and Treponema pallidum hemagglutination assay were positive, supporting the presence of a syphilis infection. Additionally, liver biopsy examination showed infiltration of inflammatory cells into the portal area and epithelioid cell granulomas. Moreover, kidney biopsy examination by both optical and electron microscopy showed a congestion of neutrophils in the capillary vessels, structural collapse of the tubules, and subepithelial deposits under the epithelium of the glomerular endothelial cells. These pathological changes were consistent with those reported previously for early syphilitic hepatitis and nephrotic syndrome in early-stage syphilis. All the symptoms, including liver and renal dysfunction, resolved after benzyl penicillin treatment was initiated. Hence, we believe early-stage syphilis should be included in the differential diagnosis of unknown liver damage and/or nephrosis.

Enhanced CT demonstrated that these masses had slowly become isodense. Consent of histopathological examination was not obtained from the patient at that time. After 6 months, these masses showed a notable increase in size and number. Ultrasound-guided biopsy was performed, and non-caseous epithelioid granulomas with necrosis andmultinuclear giant cells were observed. Based on these findings, we considered a probable diagnosis of liver tuberculosis or sarcoidosis. The QuantiFERON test and tuberculosis polymerase chain reaction results were negative. Serum calcium and angiotensin-converting enzyme levels were normal, and bilateral hilar lymphadenopathy was not present. Although a diagnosis of liver tuberculosis was not confirmed, we decided to initiate anti-tuberculosis therapy to prevent morbid progression of tuberculosis. After 6 months of therapy, the masses decreased in size.

Here, we report the case of a 33-year-old male with obstructive jaundice caused by tuberculous lymphadenitis around the pancreatic head. The patient was born in China and had immigrated to Japan at 12 years of age. He presented with acute abdominal pain and jaundice. Findings from ultrasonography, computed tomography, and endoscopic retrograde cholangiopancreatography were suggestive of a stenosis of the distal common bile duct caused by multiple low-density masses around the pancreatic head with a contrast-enhanced solid rim. We successfully diagnosed the mass as tuberculous lymphadenitis using endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). The patient was treated with anti-tuberculous combination chemotherapy for 6 months, and subsequently exhibited clinical improvement. Thus, we found that EUS-FNA was a valuable minimally invasive method for diagnosing masses that cause icterus.
[Show abstract][Hide abstract] ABSTRACT: Narrow band imaging (NBI) and flexible spectral imaging color enhancement (FICE) allow improved contrasted evaluation of the mucosal surface. However, no study has compared the utility of these two modalities. Therefore, the aim of this study was to compare the adenoma miss rate (AMR) between NBI and FICE.
A total of 55 patients (38 men, 17 women) were enrolled in this study. Patients were randomly assigned to the NBI-FICE group (NBI followed by FICE) or the FICE-NBI group (FICE followed by NBI). NBI and FICE total colonic observations were tandemly performed for each patient during the scope withdrawal with white light following cecal intubation. All detected polyps with the NBI or FICE observation were categorized into three groups according to the size and number of polyps missed.
Twenty-nine patients were assigned to the NBI-FICE group, and 26 patients were assigned to the FICE-NBI group. There was no significant difference in the overall AMR when comparing the image-enhanced endoscopy technologies (17.9 % for NBI, 26 % for FICE, p = 0.159). AMR was lower for NBI than for FICE for adenomas <5 mm in diameter (5.7 % for NBI, 12.6 % for FICE, p = 0.036). AMR was not significantly different when comparing NBI and FICE for lesions 5 to 10 mm (p = 0.967) or for lesions ≥10 mm (p = 0.269).
This study demonstrated that overall AMR was not different when comparing NBI and FICE.

[Show abstract][Hide abstract] ABSTRACT: Abnormal serum lipid profiles have been noted in patients with chronic hepatitis C virus (HCV) infection. Moreover, many reports suggest that serum lipoprotein profiles are more profoundly distorted in patients with HCV G1b infection who have an unfavorable response to pegylated interferon (peg-IFN) plus ribavirin (RBV) combination therapy. However, after the discovery of single nucleotide polymorphisms near the IL28B gene (rs8099917 and rs12979860) as potent predictive factors affecting the response to peg-IFN plus RBV, lipid factors are thought to be confounding factors.
To re-examine the significance of lipoprotein profiles on virological response to peg-IFN plus RBV combination therapy in patients with chronic HCV G1b infection, we examined cholesterol and triglyceride concentrations in each lipoprotein fraction separated by high performance liquid chromatography.
Lipoprotein profiles were examined using fasting sera from 108 patients infected with HCV G1b who had chronic hepatitis, as determined by liver biopsy. Results of lipoprotein profiles and clinical data, including IL28B genotype and amino acid substitution at aa70 of HCV G1b, were compared between patients with a sustained virological response (SVR) and non-SVR or a non-virological response (NVR) and virological responses other than NVR (non-NVR). In addition, significant predictive factors independently associated with virological response to peg-IFNα-2b plus RBV were determined by logistic regression analysis.
An increased ratio of cholesterol/triglyceride in very low-density lipoprotein (odds ratio (OR) 3.03; 95% confidence interval (CI) 1.01-9.44) along with a major genotype of rs8099917 (OR 9.09; 95% CI 2.94-33.33), were independent predictive factors for SVR. In contrast, lipid factors were not elucidated as independent predictive factors for NVR.
Examination of the fasting lipid profile has clinical importance in predicting the efficacy of peg-IFN-α-2b plus RBV combination therapy for patients with HCV G1b even after the discovery of the IL28 genotype as a potent predictive factor.
[Show abstract][Hide abstract] ABSTRACT: BACKGROUND: Endoscopic submucosal dissection (ESD) for superficial gastric neoplasm is a curative method. The aim of this study was to detect potential nonbleeding visible vessels (NBVVs) by using an infrared imaging (IRI) system. METHODS: A total of 24 patients (25 lesions) were consecutively enrolled between March 2010 and December 2010. The day after ESD, endoscopist A (K.M.), who was blinded to the actual procedure of ESD, performed esophagogastroduodenoscopy (EGD) of the post-ESD ulcer base using the IRI system. Endoscopist A marked gray/blue points in the hard-copy images with the IRI system. After the first procedure, endoscopist B (Y.Y.), who was blinded to the results recorded by endoscopist A, performed a second EGD with white light endoscopy and administered water-jet pressure with the maximum level of an Olympus flushing pump onto the post-ESD ulcer base. This test can cause iatrogenic bleeding via application of pressure to NBVV in the post-ESD ulcer. RESULTS: The IRI system detected 58 gray points and 71 blue points. The post-ESD ulcer was divided into the central area and the peripheral area. There were 14 gray points (24 %) in the central area and 44 gray points (76 %) in the peripheral area. There were 19 blue points (27 %) in the central area and 52 blue points (73 %) in the peripheral area. There was no significant difference when comparing the distribution of gray points and blue points. Bleeding occurred with a water-jet pressure in 11 of 58 gray points and in none of the blue points (P = 0.000478). Among the gray points, bleeding in response to a water-jet pressure occurred in 2 points in the central area and in 9 points in the peripheral area. CONCLUSION: The IRI system detects visible vessels (VVs) that are in no need of coagulation as blue points, and VVs have a potential risk of bleeding as gray points.
[Show abstract][Hide abstract] ABSTRACT: To identify factors associated with prognosis of hepatocellular carcinoma (HCC) after initial therapy.
A total of 377 HCC patients who were newly treated at Katsushika Medical Center, Japan from January 2000 to December 2009 and followed up for > 2 years, or died during follow-up, were enrolled. The factors related to survival were first analyzed in 377 patients with HCC tumor stage T1-T4 using multivariate Cox proportional hazards regression analysis. A similar analysis was performed in 282 patients with tumor stage T1-T3. Additionally, factors associated with the period between initial and subsequent therapy were examined in 144 patients who did not show local recurrence. Finally, 214 HCC stage T1-T3 patients who died during the observation period were classified into four groups according to their alcohol consumption and postprandial glucose levels, and differences in their causes of death were examined.
On multivariate Cox proportional hazards regression analysis, the following were significantly associated with survival: underlying liver disease stage [non-cirrhosis/Child-Pugh A vs B/C, hazard ratio (HR): 0.603, 95% CI: 0.417-0.874, P = 0.0079], HCC stage (T1/T2 vs T3/T4, HR: 0.447, 95% CI: 0.347-0.576, P < 0.0001), and mean postprandial plasma glucose after initial therapy (< 200 vs ≥ 200 mg/dL, HR: 0.181, 95% CI: 0.067-0.488, P = 0.0008). In T1-T3 patients, uninterrupted alcohol consumption after initial therapy (no vs yes, HR: 0.641, 95% CI: 0.469-0.877, P = 0.0055) was significant in addition to underlying liver disease stage (non-cirrhosis/Child-Pugh A vs B/C, HR: 0649, 95% CI: 0.476-0.885, P = 0.0068), HCC stage (T1 vs T2/T3, HR: 0.788, 95% CI: 0.653-0.945, P = 0.0108), and mean postprandial plasma glucose after initial therapy (< 200 mg/dL vs ≥ 200 mg/dL, HR: 0.502, 95% CI: 0.337-0.747, P = 0.0005). In patients without local recurrence, time from initial to subsequent therapy for newly emerging HCC was significantly longer in the "postprandial glucose within 200 mg/dL group" than the "postprandial glucose > 200 mg/dL group" (log-rank test, P < 0.05), whereas there was no difference in the period between the "non-alcohol group" (patients who did not drink regularly or those who could reduce their daily consumption to < 20 g) and the "continuation group" (drinkers who continued to drink > 20 g daily). Of 214 T1-T3 patients who died during the observation period, death caused by other than HCC progression was significantly more frequent in "group AL" (patients in the continuation and postprandial glucose within 200 mg/dL groups) than "group N" (patients in the non-alcohol and postprandial glucose within 200 mg/dL groups) (P = 0.0016).
This study found that abstinence from habitual alcohol consumption and intensive care for diabetes mellitus were related to improved prognosis in HCC patients.

[Show abstract][Hide abstract] ABSTRACT: Of 168 patients with chronic hepatitis B virus (HBV) infection-related liver disease, 20 patients who had received 100 mg of lamivudine plus 10 mg/day of adefovir dipivoxil (ADV) (ADV group) and 124 patients who had received 0.5 mg/day of entecavir or 100 mg/day of lamivudine (non-ADV group) for >1 year were enrolled. For comparative analyses, 19 well-matched pairs were obtained from the groups by propensity scores. At the time of enrollment, serum creatinine and phosphate concentrations were similar between the ADV and non-ADV groups; however, urinary phosphate (P = 0.0424) and serum bone-specific alkaline phosphatase (BAP) (P = 0.0228) concentrations were significantly higher in the ADV group than in the non-ADV group. Serum BAP was significantly higher at the time of enrollment than before ADV administration in the ADV group (P = 0.0001), although there was no significant change in serum BAP concentration in the non-ADV group. There was a significant positive correlation between the period of ADV therapy and ΔBAP (R (2) = 0.2959, P = 0.0160). Serum BAP concentration increased before increase in serum creatinine concentration and was useful for early detection of adverse events and for developing adequate measures for continuing ADV for chronic HBV infection-related liver disease.

[Show abstract][Hide abstract] ABSTRACT: Purpose. Although esophageal capsule endoscopy (ECE) is reportedly useful in the diagnosis of esophageal varices (EV), few reports have described the benefits of this technique in Asian countries. The present paper evaluates the usefulness of ECE for diagnosing EV in Japanese patients with cirrhosis. Methods. We examined 29 patients with cirrhosis (20 males and 9 females; mean age 60 years; Child-Pugh classification A/B/C; 14/14/1) using ECE followed by esophagogastroduodenoscopy (EGD). High-risk EV were defined as F2 and/or RC2 and above. Results. The sensitivity and specificity of ECE for the diagnosis of high-risk EV were 92% and 80%, respectively. Conclusions. The findings showed that ECE is a highly sensitive method of diagnosing high-risk EV that requires endoscopic or pharmacological therapy. Thus, ECE might be a useful method for the screening and followup of EV in patients with cirrhosis.

[Show abstract][Hide abstract] ABSTRACT: The life cycle of the hepatitis C virus (HCV) is closely related to host lipoprotein metabolism. Serum levels of lipid are associated with the response to pegylated interferon plus ribavirin (PEG-IFN/RBV) therapy, while single nucleotide polymorphisms (SNPs) around the human interleukin 28B (IL28B) gene locus and amino acid substitutions in the core region of the HCV have been reported to affect the efficacy of PEG-IFN/RBV therapy in chronic hepatitis with HCV genotype 1b infection. The aim of this study was to elucidate the relationship between serum lipid and factors that are able to predict the efficacy of PEG-IFN/RB therapy, with specific focus on apolipoprotein B-100 (apoB-100) in 148 subjects with chronic HCV G1b infection. Our results demonstrated that both the aa 70 substitution in the core region of the HCV and the rs8099917 SNP located proximal to the IL28B were independent factors in determining serum apoB-100 and low-density lipoprotein (LDL) cholesterol levels. A significant association was noted between higher levels of apoB-100 (P = 1.1 × 10(-3)) and LDL cholesterol (P = 0.02) and the subjects having Arg70. A significant association was also observed between subjects carrying the rs8099917 TT responder genotype and higher levels of apoB-100 (P = 6.4 × 10(-3)) and LDL cholesterol (P = 4.2 × 10(-3)). Our results suggest that apoB-100 and LDL cholesterol are markers of impaired cellular lipoprotein pathways and/or host endogenous interferon response to HCV in chronic HCV infection. In particular, serum apoB-100 concentration might be an informative marker for judging changes in HCV-associated intracellular lipoprotein metabolism in patients carrying the rs8099917 responder genotype.

[Show abstract][Hide abstract] ABSTRACT: The effects of an oral rehydration solution (ORS) on fatigue were studied in workers engaged in manual work during the summer.
One hundred and fifty-three workers engaged in loading cargo onto aircraft at Tokyo International Airport who consented to participate in the study were the subjects. The study was carried out on two summer days with fine weather during the daytime shift. The subjects were randomly divided into two groups: with one group restricted to ORS intake and the other group having free-choice of their favorite drink (FAD) in a randomized crossover study. The subjects were asked about the amount of beverage that they consumed and the type of FAD that they chose on the days of the survey. The effects of the ORS and the FAD were compared using a visual analogue scale (VAS) to determine the degree of fatigue experienced immediately after completing work.
The average wet bulb globe temperature (WBGT) on the survey days was 30 degrees C. The beverage intake during work was 1,000 ml for most participants and the most commonly chosen types of FAD were tea and coffee. The fatigue VAS was significantly lower on the ORS intake days than on the FAD intake days (50.0 +/- 18.3 vs. 53.9 +/- 16.3).
The results of this study suggest that the intake of ORS during outdoor work in a hot environment would be effective for preventing industrial accidents and heat stroke. It is important to select an appropriate drink to ensure adequate intake of water and electrolytes.

[Show abstract][Hide abstract] ABSTRACT: A 29-year-old woman was referred to our hospital for the intensive examination of leg edema and hypoproteinemia. CT scan of showed multiple thin-walled cysts in both lungs, suggesting lymphangioleiomyomatosis. CT scan of the abdomen, lymphoscintigraphy showed enlarged abdominal lymph nodes. Protein loss from the gastrointestinal tract was documented by measurement of the clearance of alpha-1 antitrypsin from the plasma using a 72 h stool collection and (99m)Tc human serum albumin scintigraphy. We thought that secondary lymphangiectasia with lymphangioleiomyomatosis caused protein-losing gastroenteropathy. Dietary therapy resulted in symptomatic improvement.
