Objective: Transcatheter arterial chemoembolization (TACE) is an essential therapy for patients with hepatocellular carcinoma (HCC) in whom administering other treatments such as liver transplantation, resection or local therapy is not feasible. The purpose of our study was to determine the independent risk factors for one-year recurrence and two-year mortality in patients treated solely with TACE., Methods: We conducted a retrospective cohort study of 34 consecutive patients (Group 1) with incident HCC who were treated solely with epirubicin-based TACE between April 2004 and March 2009. A subgroup analysis was performed among 24 patients (Group 2) who underwent complete TACE confirmed with abdominal computed tomography (CT) one month later. Tumor recurrence was evaluated using contrast CT every three months after the initial TACE. We calculated Kaplan-Meier estimates and performed a multiple regression analysis using a Cox-proportional hazard model., Results: The patients in Group 1 (men, 59%), all of whom had liver cirrhosis, underwent TACE as the sole therapy for HCC. Kaplan-Meier estimates revealed a two-year survival rate [95% CI] of 70% [48-84%]. For the non-Child A patients, the adjusted hazard ratio (HR) [95% CI] for two-year survival was 7.1 [1.06-51.7]. In Group 2, the Kaplan-Meier estimate of the one-year recurrence rate [95% CI] was 61% [42-81%]. The adjusted HRs [95% CIs] for one-year recurrence for age and indocyanine green (ICG) 15-min >30% were 1.1 [1.0-1.26] and 7.87 [1.94-45.1], respectively., Conclusion: Non-Child A cirrhosis is an independent risk factor for two-year mortality in patients treated solely with TACE. For ICG 15-min >30%, careful monitoring for HCC recurrence at one year, even after complete TACE, is warranted.

Background: Plasma ammonia has been used in emergency departments to assess whether or not generalized convulsion attacks exist in patients who are suspected of having convulsions. However, there are few reports that have assessed the relationship between generalized convulsions and hyperammonemia. The clinical significance of plasma ammonia measurements in the diagnosis of generalized convulsions is investigated in this study., Objective: A total of 293 patients who were transported by ambulance to the emergency department of St. Luke's International Hospital, Tokyo, Japan under suspicion of convulsive seizure or disturbance of consciousness were studied., Methods: The objectives were divided into two groups--"Convulsion" and "Non-convulsion"--according to the information provided by witnesses. Bivariate and multivariate analyses were carried out for patient background, clinical course, past medical history and blood test results., Results: All 11 items showing significant differences on the bivariate analysis were included in the multivariate analysis. Of these, age, total Glasgow Coma Scale score, plasma ammonia level and arterial lactate level showed a significant difference and are recognized as independent findings for the diagnosis of generalized convulsion. The plasma ammonia level had an odds ratio of 14.8 (95% CI, 3.2 to 111.5; p<0.01), 53% sensitivity and 90% specificity when 65 µg/dL was used as the cut-off value., Conclusion: Plasma ammonia values rise during generalized convulsion. Measurement of plasma ammonia is clinically highly significant as an independent finding during the diagnosis of generalized convulsion.

Purpose: Obesity, smoking and alcohol are modifiable putative risk factors for colorectal neoplasms (CRN) and hyperplastic polyps (HP). The aim of this study was to evaluate the strength of association between these modifiable risk factors and colorectal polyps., Methods: These risk factors were assessed by using a questionnaire completed by the patient prior to colonoscopy. Eight hundred-seventy consecutive patients satisfying inclusion criteria who had undergone a complete colonoscopy were divided into 4 groups: CRN (n=194), HP (n=132), CRN and HP (n=42) and control (neither CRN nor HP; n=586). Multiple logistic regression was performed., Results: The ORs [95%CI] of both CRN and HP for incremental body mass index expressed in 2 categories (>or=22, >or=25) were 2.12 [1.00, 4.50] and 1.41 [0.53, 3.77], respectively. The ORs [95%CI] of CRN and HP for heavy smoking of over 20 pack-years were 1.66 [1.05, 2.64] and 1.67 [1.01, 2.77], respectively. The ORs of CRN and HP for habitual alcohol drinking (median ethanol intake 32 g/day and interquartile range 18-40 g/day) were 1.31 [0.86, 1.98] and 1.91 [1.06, 3.47], respectively. CRN and HP were correlated with each other (p=0.0043, chi-square test). Aging was a significant risk factor for all three groups of colorectal polyps., Conclusion: These findings are especially important since smoking and alcohol consumption are modifiable risk factors. Heavy smokers should be encouraged to quit to reduce their risk of CRN and HP. Habitual drinkers should be warned of the risk of HP. HP can be a marker of coincidence of CRN.

A 49-year-old asthmatic woman with a history of drug allergy to aspirin and penicillin presented to the hospital with fever, dark urine, general exanthema and fatigue. Physical examination revealed jaundice. She had been taking four different over-the-counter drugs. Laboratory examination showed eosinophilia, elevated Ig E, hyperbilirubinemia and elevated liver function tests. HBs Ag, anti-HCV Ab and Ig M anti-HA were negative. She was initially diagnosed with drug-induced hepatitis and was treated with steroids. However, liver dysfunction with eosinophilia relapsed after discontinuing steroids. Liver biopsy revealed eosinophilic infiltration. Steroids were discontinued after the start of 6-mercaptopurine.
