RESUMO
Endoscopic submucosal dissection (ESD) has become the first-line treatment for early gastric neoplasms; however, a subset of patients treated by this method develop aspiration pneumonia. We conducted a comprehensive prospective analysis of the factors contributing to post-ESD aspiration pneumonia in early gastric neoplasms in this study, with special focus on whether pre-treatment oral care can prevent aspiration pneumonia. Sixty-one patients who underwent ESD for gastric neoplasms were randomly assigned to the oral care or control groups. ESD was performed under deep sedation. Of 60 patients whose data were available for analysis, 5 (8.3%) experienced pneumonia confirmed either by chest radiography or computed tomography. Although no difference in the rate of pneumonia was found between the control and oral care groups, the post-oral care bacteria count was significantly higher in the saliva of patients who developed pneumonia compared to those without pneumonia. In addition, the presence of vascular brain diseases and the dose of meperidine were also significantly associated with the occurrence of pneumonia. These results suggest that the number of oral bacteria as well as pre-existing vascular brain diseases and high-dose narcotics can affect the incidence of post-ESD pneumonia.

BACKGROUND: Fecal lactoferrin has been introduced as a useful tool for the diagnosis and monitoring of inflammatory bowel disease (IBD). The aim of this study was to assess if fecal lactoferrin can be employed to predict or estimate the effect of granulocyte and monocyte adsorptive apheresis (GMA) in ulcerative colitis (UC). METHODS: This was a prospective study involving 21 patients with UC. Patients with moderately-to-severely active UC who were scheduled to undergo GMA were recruited. Changes in fecal lactoferrin concentration were compared between the GMA-responder and -nonresponder groups. RESULTS: In the GMA-responder group, fecal lactoferrin significantly increased 1 week after the introduction of GMA and then significantly decreased after GMA sessions. Fecal lactoferrin concentrations were significantly higher in the GMA-responder group than in the GMA-nonresponder group at 1 and 2 weeks after the introduction of GMA. Multivariate logistic regression analysis revealed that fecal lactoferrin concentration 1 week after the introduction of GMA was the most contributing factor for the effectiveness of GMA in patients with UC. CONCLUSIONS: In the GMA-responder group, fecal lactoferrin concentration significantly increased 1 week after the introduction of GMA. Fecal lactoferrin may be beneficial for predicting clinical response of GMA in patients with UC at an early stage of GMA treatment.

BACKGROUND: High-dose (4.0 g/day) mesalazine is typically used for induction therapy, but its efficacy as maintenance therapy remains to be determined. We conducted a multicenter retrospective study to investigate the efficacy of continuous treatment with 4.0 g/day of mesalazine. MATERIAL/METHODS: Japanese ulcerative colitis (UC) patients receiving acute induction therapy with 4.0 g/day mesalazine were enrolled and followed. Those who clinically improved or who achieved clinical remission were categorized into 2 sub-groups according to the median duration of treatment with 4.0 g/day of mesalazine. The clinical relapse frequency and the time to relapse were analyzed. RESULTS: We enrolled 180 patients with active UC, and then 115 patients who clinically improved or who achieved clinical remission after treatment with 4.0 g/day mesalazine were categorized into 2 sub-groups according to the median of treatment duration: a short-term treatment group (≤105 days, n=58) and a long-term treatment group (>105 days, n=57). Overall, 45 (39.1%) patients relapsed: 28 (48.3%) in the short-term treatment group and 17 (29.8%) in the long-term treatment group. This difference was statistically significant (p<0.05). The relapse-free rate in the long-term treatment group was significantly higher than that in the short-term treatment group (p<0.05). The mean time to relapse in the long-term treatment group was significantly longer than that in the short-term treatment group (425.6±243.8 days vs. 277.4±224.5 days; p<0.05). CONCLUSIONS: Long-term continuous treatment with high-dose mesalazine (4.0 g/day) may be more effective than short-term treatment for maintenance of remission in UC patients.

BACKGROUND: The incidence of hepatocellular carcinoma (HCC) continues to increase in Japan, but the clinical characteristics of Japanese patients with HCC have not been well described. The aim of this study was to determine the frequencies and utilities of elevated a-fetoprotein (AFP) and des-gamma-carboxy prothrombin (DCP) levels as biomarkers in cryptogenic HCC. MATERIAL/METHODS: A total of 2638 patients with HCC diagnosed between 1999 and 2010 in the Nagasaki Association Study of Liver (NASLD) were recruited for this study. The cause of HCC was categorized into 4 groups; HCC-B, HCC-C, HCC-BC, and HCC-nonBC. The significance of factors was examined for HCC-nonBC using logistic regression analysis in all patients. RESULTS: Multivariate analysis identified age, sex, BMI, alcohol consumption, platelet count, AST, ALT, AFP, DCP, and TNM stage as independent and significant risk factors for HCC-nonBC. According to TNM stage, the median AFP levels in HCC-nonBC with TNM stages I, II, and III were significantly lower than in either HCC-B or HCC-C. In TNM stage IV, the median AFP level in HCC-nonBC was significantly lower than in either HCC-B or HCC-BC. The median DCP levels in HCC-nonBC with TNM stages I and II were significantly higher than those in either HCC-B or HCC-C. In TNM stage III, the median DCP level in HCC-nonBC was significantly higher than that in HCC-C. CONCLUSIONS: DCP was more sensitive than AFP for the diagnosis of early stage cryptogenic HCC. DCP should be used as the main serum test for cryptogenic HCC detection.

BACKGROUND: The age of patients with advanced hepatocellular carcinoma (HCC) eligible for molecular-targeted drug treatment is increasing. We assessed liver function after lenvatinib administration according to age in patients with advanced HCC. PATIENTS AND METHODS: In this retrospective, multicenter, observational study, we reviewed the records of patients with HCC who received lenvatinib treatment (March 2018-March 2020). Liver function was measured using the Albumin-Bilirubin Index (ALBI). RESULTS: Of 119 patients, with a median age of 72.0 years, median overall survival was 15.3 months. Overall survival was significantly better in the group which maintained liver function (p=0.02). Older age (≥72 years) was associated with liver-function deterioration within 8 weeks (odds ratio=2.47, 95% confidence interval=1.06-5.75, p=0.035). The ALBI score was significantly higher in the older group at 4 and 8 weeks after lenvatinib administration. CONCLUSION: Lenvatinib administration was more likely to adversely affect liver function in older patients; dose adjustment should be considered in such patients.

We report a case of hepatic portal venous gas (HPVG) caused by transient type ischemic enteritis. The patient was a 65-year-old woman, previously given a diagnosis of hypertension and diabetes mellitus. She was admitted to our hospital because of vomiting and epigastric pain. Abdominal computed tomography showed dilatation of the stomach and small intestine, with hepatic portal and superior mesenteric venous gas. Upper gastrointestinal endoscopy showed diffuse edematous and erosive change, and an extensive ulcer in the duodenum. There was no muscular defence, and physical and laboratory examinations did not indicate necrotic bowel. We diagnosed as HPVG caused by ischemic enteritis, and she responded to conservative treatment. We discuss a rare case of HPVG caused by transient type ischemic enteritis with references.

BACKGROUND/AIMS: A new prognostic staging system, the SLiDe (S, stage; Li, liver damage; De, des-gamma-carboxy prothrombin) score was recently proposed. We examined 207 HCC patients following hepatic resection to determine the usefulness of this staging system for HCC patients after surgery. METHODOLOGY: Disease-free and overall survival rates were calculated according to the Kaplan-Meier method, and differences between groups were tested for significance using the log-rank test. RESULTS: Regarding disease-free survival, there were no significant differences in survival between SLiDe score 0 vs 1, between score 2 vs 3, and between score 4 vs 5. There were significant differences between 0-1 vs 2-3 (p < 0.01) and between 2-3 vs 4-5 (p < 0.01). Regarding overall survival, there were no significant differences in survival between score 0 vs 1, between score 2 vs 3, and between score 4 vs 5. There were significant differences between 0-1 vs 2-3 (p < 0.05) and between 2-3 vs 4-5 (p < 0.01). CONCLUSIONS: The SLiDe score, a staging system that combines tumor factors, a tumor marker and hepatic function, might be a better predictor of prognosis in HCC patients who have undergone hepatic resection.

RATIONALE: Mucormycosis is a rare opportunistic fungal infection with poor prognosis. The incidence of mucormycosis has been increasing, and it is a threat to immunocompromised hosts. We present a case of gastric mucormycosis complicated by a gastropleural fistula during immunosuppressive treatment for adult-onset Still disease (AOSD). PATIENT CONCERNS: An 82-year-old woman diagnosed with AOSD who developed gastric ulcers during the administration of an immunosuppressive therapy with corticosteroids, cyclosporine, and tocilizumab complained of melena and epigastralgia. Esophagogastroduodenoscopy showed multiple ulcers covered with grayish or greenish exudates. DIAGNOSES: The patient diagnosed with mucormycosis based on culture and biopsy of the ulcers, which showed nonseptate hyphae branching at wide angles. Mucor indicus was identified using polymerase chain reaction. INTERVENTIONS AND OUTCOMES: Although liposomal amphotericin B was administered, gastric mucormycosis was found to be complicated by a gastropleural fistula. The patient died because of pneumonia due to cytomegalovirus infection, and autopsy revealed the presence of Mucorales around the fistula connecting the stomach and diaphragm. LESSONS: Gastric mucormycosis is refractory to treatment and fatal. Surgical resection, if possible, along with antifungal drugs can result in better outcomes.

BACKGROUND/AIMS: We evaluated patients with nonalcoholic fatty liver disease (NAFLD) and compared the clinical and pathological features to identify the risk factors for NAFLD with severe fibrosis. METHODS: One hundred and eighty-two patients with biopsy-confirmed NAFLD from various medical centres were recruited into this study. RESULTS: The variables that were significantly associated with severe steatosis were male gender (mild:severe=36%:53%, P=0.02), younger age (mild:severe=57%:82%, P>0.001) and absence of type 2 diabetes (mild:severe=43%:71%, P>0.001). There was no significant difference in the degree of inflammation among the clinical groups. The variables that were significantly associated with severe fibrosis were female gender (mild:severe=54%:84%, P=0.002), older age (> or = 60 years old) (mild:severe=29%:53%, P=0.020), type 2 diabetes (mild:severe=42%:71%, P=0.020) and hypertension (mild:severe=24%:53%, P=0.002). Although there were more obese patients in the group with severe fibrosis, the association was not statistically significant (mild:severe=67%:78%, P=0.229). The prevalence of high serum triglyceride levels was similar between the two groups. The N (Nippon) score (total number of risk factor) could significantly predict severe fibrosis in NAFLD patients (1.48 +/- 1.14 vs. 2.66 +/- 0.94, P<0.001). CONCLUSIONS: The N score can be used to predict severe fibrosis in cases of NAFLD.

BACKGROUND/AIMS: Autoimmune hepatitis (AIH) is a chronic liver disease characterized by the presence of antinuclear antibodies. However, antimitochondrial antibodies (AMA) and bile duct changes, which are the characteristics of primary biliary cirrhosis (PBC), can be detected in AIH patients. METHODOLOGY: Twenty patients with definite AIH were prospectively followed-up, and the serial changes in AMA profiles were determined. We also examined the correlations between these antibodies and histopathological findings in the liver. RESULTS: Of the 20 patients, 7 (35%) had bile duct injury, and 2 of these 7 patients also showed chronic nonsuppurative destructive cholangitis or ductopenia of interlobular bile ducts histopathologically. Serologically, 7 patients (35%) were positive for AMA at least once by immunoblotting during the follow-up periods. There were no significant differences in biochemical hepatobiliary indices, the presence of bile duct lesions, or the changes in biochemical profiles between AMA-positive and AMA-negative AIH patients during the follow-up periods. CONCLUSIONS: We confirmed that AMA and certain histopathological findings that are characteristics of PBC can be seen in some AIH patients. However, there was no significant correlation between AMA positivity and the histopathological findings in the liver, or biochemical hepatobiliary indices. Thus, the clinical implications of AMA in AIH patients remain unclear.

BACKGROUND/AIMS: In advanced hepatocellular carcinoma (HCC) with vascular involvement of major vessels, patients have a poor prognosis after surgical treatment. METHODOLOGY: Patient outcomes after surgical resection and the usefulness of adjuvant chemotherapy were examined in 12 patients with major hepatic vessel involvement who underwent hepatectomy with combined resection of major blood vessels. RESULTS: The main portal vein was resected in 8 patients, the inferior vena cava in 3, hilar bile duct in 2 and hepatic artery in 1. Eleven patients underwent hemihepatectomy and 1 underwent segment 4 and 5 resection. The portal branch was repaired by venoplasty. The vena cava wall was repaired by suture closure. The hepatic artery was replaced by end-to-end anastomosis. The bile duct was repaired by Roux-en-Y hepaticojejunostomy. Although 2 patients had biliary leakage, there were no postoperative complications in 10 patients. The tumor recurrence rate was 83% in the early period and cancer death within 1 year was observed in 6 (50%), while 3 with tumor recurrence survived for more than 2 years and 2 survived without recurrence. In 233 HCC patients who underwent hepatectomy, 10 patients including 2 present cases received adjuvant chemotherapy at the time of tumor recurrence and 2 had complete responses. While in 11 patients receiving chemotherapy without resection, the response rate using Gemcitabine (66%) was higher than that using low dose Cisplatin plus 5-Fluorouracil (22%). CONCLUSIONS: Complete surgical resection combined with main vascular resection could be safely performed in most advanced stage HCC patients and adjuvant chemotherapy in the early period after resection would be necessary, which may achieve longer survival in some patients even in the advanced stage.

A 51-year-old man visited the Sasebo General Hospital because of a niche and a ductal lesion with reflux of barium in the lesser curvature of the gastric body in the upper gastrointestinal series of an annual medical checkup. Endoscopic examination showed an ulcer and a depressed lesion draining yellowish serous liquid in the stomach. Abdominal CT scan and MRCP revealed the ductal structure reached from the lesser curvature of the gastric body to the left lobe of the liver besides the ordinary pancreatobiliary system. ERCP showed normal common bile duct, gall bladder, and right intrahepatic bile duct, while the fistulography using cannula through the gastric depressed lesion revealed an accessory bile duct communicating to the left intrahepatic bile duct. The both biliary systems were completely separated, resulting in the diagnosis of double common bile duct of type IIIa.

AIM: Bile duct injury has been thought to be absent in autoimmune hepatitis (AIH), but recent studies have indicated that AIH patients do have bile duct injury. In this study, the intracellular balance of oxidative stress and cytoprotection in biliary epithelial cells was investigated to clarify the pathogenesis of bile duct injury in AIH. METHODS: The intracellular status of oxidative DNA damage caused by oxidative stress and glutathione, an endogenous cytoprotective molecule, were examined in patients with AIH, primary biliary cirrhosis (PBC), and normal controls by immunostaining of 8-hydroxydeoxyguanosine (8-OHdG) and glutathione-S-transferase-pi. RESULTS: Immunohistochemically, 8-OHdG expression was detected as abundantly in the damaged bile ducts of AIH patients as in PBC patients. Moreover, in AIH, 8-OHdG expression was detected in damaged bile ducts more than in undamaged bile ducts. Glutathione-S-transferase-pi expression was relatively preserved in the damaged bile ducts of AIH patients compared to PBC patients, reflecting preservation of intracellular glutathione. CONCLUSIONS: In AIH, oxidative stress and DNA damage may be involved in the pathogenesis of bile duct injury in a manner similar to that found in PBC. However, relatively preserved intracellular glutathione may play a key role in preventing progressive bile duct loss following bile duct injury in AIH.
RESUMO
Although antimitochondrial antibody (AMA) is the characteristic serological feature of primary biliary cirrhosis (PBC), its pathogenic role remains unclear. In our previous study, we reported a positive correlation between immunoglobulin (Ig) A class anti-2-oxo-acid dehydrogenase complex (2-OADC) and histopathological stage. To determine whether the appearance of IgA class anti-2-OADC by immunoblotting represents an early marker of more aggressive disease or whether it is late finding during the disease course of PBC, we tested not only the entire IgA class but also IgA1, IgA2 and secretory IgA class anti-2-OADC in serial serum samples from 15 patients with PBC. During the median observation period of 51 months, four cases showed histopathological progression (from stage 1 to 2, stage 1 to 3, stage 1 to 4 and stage 2 to 4). There was no statistically significant correlation between the above IgA class anti-2-OADCs and histopathological progression. There was no significant correlation between histopathological stages and IgA2 class anti-2-OADC or secretory IgA class anti-2-OADC by immunoblotting. IgA class anti-2-OADC was more frequent in stages 3-4 than in stages 1-2 (p = 0.0049), but IgA1 class anti-2-OADC was more frequent in stages 1-2 than in stages 3-4 (p = 0.0232). Our present study demonstrated that serum IgA class 2-OADC was not a predictive marker of histopathological progression but was associated with the histopathological stage of PBC. Although the IgA class AMA may have a specific pathogenic role for PBC, the discrepant results between IgA and IgA1 class anti-2-OADC should be further assessed to investigate different functional activities depending on their molecular form.

BACKGROUND: The "Liver damage" classification proposed by the Liver Cancer Study Group of Japan and Child-Pugh classification are both useful classifications for hepatic function. However, the factors responsible for the difference between the two classifications have not been fully investigated. METHODS: The medical records of 594 admissions of 220 patients with hepatocellular carcinoma (HCC) were retrospectively analyzed for encephalopathy, ascites, serum bilirubin and albumin, plasma retention rate (%) at 15min after injection of 0.5mg/kg of indocyanine green (ICG R15), and prothrombin time. RESULTS: Of 594 admissions, ICG R15 was tested in 337 (56.7%). The Child-Pugh classification was evaluated in all 594 admissions, but the "Liver damage" could be evaluated in 510 (85.9%) due to the lack of ICG R15 results. Of the 594 admissions, 372 (62.6%), 162 (27.3%), and 60 (10.1%) were Child-Pugh grade A, B, and C, respectively. Of the 510 admissions, 219 (42.9%), 202 (39.6%), and 89 (17.5%) were "Liver damage" grade A, B, and C, respectively. The grade of "Liver damage" was similar to that of Child-Pugh classification in 369 (72.4%), under-evaluated in 138 (27.1%), and over-evaluated in 3 (0.6%). The Child-Pugh classification was statistically a better classification for predicting outcome than "Liver damage", but the "Liver damage" had better stratification ability than Child-Pugh classification in patients with relatively good liver function. CONCLUSIONS: Although the "Liver damage" could not be evaluated in some cases due to the lack of ICG R15 results, this classification system is useful in the evaluation and prediction of outcome of patients with early-stage liver diseases.
RESUMO
Octachlorodibenzo-p-dioxin (OCDD)-added, pretreated fly ash was heated under vacuum at sample temperatures ranging from T(s)=450 to 650 K. The fly ash and liquid nitrogen-cooled trap samples were analyzed for DD/DF through OCDD/DF. The total amounts of DD through OCDD decrease with increasing T(s), which indicates that dechlorination/hydrogenation (DCH) reactions are not the only reaction channels. Reduction of toxic equivalent (TEQ) for PCDDs by more than 99% was achieved in the fly ash by the vacuum heat treatment at T(s)=650 K for 4 h. The total amount of PCDDs and DD detected in the liquid nitrogen-cooled trap relative to that of added OCDD was about 17%, i.e., PCDDs and DD which were adsorbed to the fly ash surfaces can evaporate into the gaseous phase. The difference between the evaporation behavior of PCDDs in the present and the previous studies is discussed in the light of their states of existence.

A 46-year-old man complaining right lateroabdominal pain and dysphagia was admitted our hospital. The CT examination revealed the low density area spreading through the mediastinum. The patient's condition improved with fast and antibiotics. He was discharged from the hospital, having an equivocal diagnosis. Seven months later, his symptoms relapsed and he was hospitalized again. Further evaluation confirmed that his disease was the mediastinal pancreatic pseudocyst occurred by a pancreatic stone. The pseudocyst resolved twice with conservative therapy, fast and intravenous injection of antibiotics. We consider it a rare case, because mediastinal pancreatic pseudocyst generally have the tendency of becoming severe. Finally the operation was performed for depriving the pancreatic stone, which was the cause of pancreatic pseudocyst.

A 36-year-old Japanese woman with intestinal Behcet's disease was admitted to our hospital due to a recurrent ileocecal ulcer. Because infliximab (IFX) showed secondary failure, IFX was switched to adalimumab (ADA). After the third injection of ADA, she was unexpectedly 4-weeks pregnant. ADA was continued until 20 gestational weeks. Remission of the disease activity was maintained during pregnancy, and the birth was uneventful. The ileocecal ulcer disappeared after her delivery. ADA was detected in the umbilical blood after 119 days from the last infusion. The placental transition and timing of neonatal vaccination should be considered in cases of pregnancy with TNF antibody therapy.
