Transarterial chemoembolization (TACE) is the worldwide procedure performed for patients with various stage hepatoceullar carcinoma (HCC), but is not yet considered as curative treatment because of relatively high local recurrence rate. Moreover, many clinicians frequently experience treatment failure (incomplete necrosis or stage progression etc.) after repeated TACE, but no clear guidelines have been recommended about salvage treatment modalities for this situation. Recently, studies for combination of radiation therapy and TACE for HCC with TACE refractoriness have been tried and reported better therapeutic efficacy. Based on above suggestions, we herein offer our experience of a patient with macrovascular invasion developed after repeated TACE that achieve complete remission by stereotactic body radiation therapy. Further study, maybe regarding a combination of locoregional and systemic therapy, is necessary on how to manage HCC patients with TACE refractoriness.

BACKGROUND/AIMS: This study investigated the antiviral effects of tenofovir disoproxil fumarate (TDF) monotherapy in nucleos(t)ide analogue (NA)-naive and NA-experienced chronic hepatitis B (CHB) patients. METHODS: CHB patients treated with TDF monotherapy (300 mg/day) for > or =12 weeks between December 2012 and July 2014 at a single center were retrospectively enrolled. Clinical, biochemical, and virological parameters were assessed every 12 weeks. RESULTS: In total, 136 patients (median age 49 years, 96 males, 94 HBeAg positive, and 51 with liver cirrhosis) were included. Sixty-two patients were nucleos(t)ide (NA)-naive, and 74 patients had prior NA therapy (NA-exp group), and 31 patients in the NA-exp group had lamivudine (LAM)-resistance (LAM-R group). The baseline serum hepatitis B virus (HBV) DNA level was 4.9+/-2.3 log IU/mL (mean+/-SD), and was higher in the NA-naive group than in the NA-exp and LAM-R groups (5.9+/-2.0 log IU/mL vs 3.9+/-2.0 log IU/mL vs 4.2+/-1.7 log IU/mL, P<0.01). The complete virological response (CVR) rate at week 48 in the NA-naive group (71.4%) did not differ significantly from those in the NA-exp (71.3%) and LAM-R (66.1%) groups. In multivariate analysis, baseline serum HBV DNA was the only predictive factor for a CVR at week 48 (hazard ratio, 0.809; 95% confidence interval, 0.729-0.898), while the CVR rate did not differ with the NA experience. CONCLUSIONS: TDF monotherapy was effective for CHB treatment irrespective of prior NA treatment or LAM resistance. Baseline serum HBV DNA was the independent predictive factor for a CVR.

OBJECTIVETo identify the position of traditional herbal medicine in dementia research field using mapping technology.

METHODSKeywords for dementia and traditional herbal medicine for treating dementia were used to extract scientific articles from the Web of Science database from January 2000 to July 2010. A co-occurrence matrix was created based on the concurrent set of author's keywords occurring in each scientific article, and technology network maps were created from similarity index matrices.

RESULTSTwenty specialized research areas were identified in the dementia field, and the relationship strength was 0.2-0.6. Many research fields were associated with diagnosis and risk factors for dementia. Additionally, the mechanism or cause of dementia is an actively studied field. Traditional herbal medicine for treating dementia was located on a map near the cortical dementia diagnosis and therapy, and frontotemporal dementia research field with a relationship strength of 0.53 and 0.31-0.33 respectively, which demonstrates that traditional herbal medicine for dementia occupies an independent research area with a relationship to existing scientific research fields.

CONCLUSIONTraditional herbal medicine can provide an alternative and complementary approach for treating dementia as evidenced by a scientific mapping analysis.

BACKGROUND/AIMS: Adequate screening colonoscopy in the general population decreases the mortality associated with colorectal cancer through detection and removal of adenomatous polyps. Prolonged colonoscopic withdrawal times (>6 min) are reportedly beneficial for adenoma detection rates (ADRs). However, the quality of the endoscopist compared with colonoscopic withdrawal times is not known. The aims of this study were to investigate the difference in ADRs between trainees and experienced examiners. METHODS: A total of 967 consecutive patients who underwent screening colonoscopy in a single University hospital from June 2010 to November 2011 were enrolled in this prospective observational study. Colonoscopy was performed by four experienced staff and seven gastroenterology fellows. RESULTS: Seven gastroenterology fellows performed 633 colonoscopies and four experienced staff performed 334 colonoscopies. The overall detection rates of colorectal adenoma were 31.5% with ADRs of fellows and staff of 29.4% and 35.6%, respectively (p=0.047). Fellows also showed lower advanced ADRs (5.7% vs. 9.9%, p=0.016), and fellows had longer mean withdrawal times than staff (12.4+/-4.9 min vs. 8.2+/-4.1 min, p<0.001). Multivariate analysis showed significantly increased ADRs and advanced ADRs for staff compared with fellows (adjusted OR 2.41, 95% CI 1.70-3.43; adjusted OR 2.55, 95% CI 1.47-4.45, respectively). CONCLUSIONS: ADRs were significantly lower when colonoscopy was performed by trainees, although withdrawal times were longer than those of staff. Our results demonstrated that the quality of colonoscopy, as measured by ADRs, may be improved by experienced examiners.

Chronic intestinal pseudo-obstruction (CIPO) is a rare digestive syndrome characterized by symptoms and signs of intestinal obstruction in the absence of mechanical obstruction. A 48-year-old female presented at our facility with severe abdominal pain and vomiting. Simple abdominal radiography revealed small bowel gas and ileus. Computed tomography also revealed a dilated small bowel, but there was no evidence of mechanical obstruction. Esophageal function was decreased based on high-resolution manometry and the gastric emptying time was prolonged on a gastric emptying scan. The patient recovered with conservative treatment. We report a case of chronic intestinal pseudo-obstruction with esophageal and gastric dysfunction.

Bloodstain pattern analysis is a forensic discipline that reconstruct events of a crime scene by analyzing sizes, shapes, distributions, positions of bloodstains. Bloodstain pattern can be classified into the low velocity, medium velocity, and high velocity system. Velocities in this system represent the velocity of the wounding agent (the force applied) and not to the velocity of the blood in flight. Thus there is no reference system about the velocity of the blood in flight in the existing bloodstain classification system. Applying bloodstain pattern analysis to the real crime case, we needed to have the reference system of velocities of impact spatter, cast-off spatter, and expectorate spatter. Therefore we measured the velocities of these spatters using high speed camera and we analyzed the results. In this experiments the average velocity of impact spatter that generated by swinging a hammer with all experimenter's strength at the pool of blood is about 4.7 times faster than that of swing cast-off spatter that generated by swinging a red-wat hammer with all experimenter's strength, and about 3.9 times faster than that of expectorate spatter that generated by emitting blood from the mouth with all experimenter's strength. The velocities of cast-off spatter and expectorate spatter, however, showed similar distributions. Our experiments that measure the velocities of droplets of blood spatters in flight under the specific conditions that generated at fastest speed can give some reference to the classification system of velocities of bloodstains which is not distinct up to now, as well as some real bloodshed crime cases.

BACKGROUND/AIMS: This study investigated the efficacy and safety of docetaxel/cisplatin/5-fluorouracil (DCF) combination chemotherapy as a first-line treatment in patients with advanced gastric cancer. METHODS: The study enrolled 48 patients diagnosed with unresectable pathologically proven gastric cancer who received DCF combination chemotherapy between April 2006 and August 2009. The dose administered was docetaxel 75 mg/m2 for 1 h and cisplatin 75 mg/m2 for 90 min on day 2, and 5-FU 750 mg/m2 for 24 h on days 1-5, every 3 weeks. The response was assessed every three cycles. The toxicity was evaluated for every chemotherapy course according to the National Cancer Institute (NCI) toxicity criteria ver. 2.0. RESULTS: The median age of the patients was 58 years (range 31-78 years). The median overall survival was 11.5 months (2.3-28.2 months) and the median time to progression was 5.5 months (0.3-18.9 months). No complete remission occurred. Of the patients, 56% achieved a partial response, 21% stable disease, and 10% progressive disease. The overall response rate was 56%. During a total 292 cycles, anemia worse than NCI toxicity grade 3 occurred in 2%, leukopenia in 33.1%, neutropenia in 67.1%, and thrombocytopenia in 4.4%. Neutropenic fever occurred in 33 cycles (11.3%), dose reduction due to side effects in 165 cycles (56.5%), and a regimen change due to side effect in five cycles (1.7%). CONCLUSIONS: Combination chemotherapy with docetaxel, cisplatin, and 5-FU is efficacious, but has relatively high toxicity. A DCF protocol that maximizes its efficiency, while minimizing toxicity, would be more useful as a first-line treatment in patients with advanced gastric cancer.

This cohort study is a collaborative effort of 8 institutions. The goal is to establish a large scale cohort that can be followed for 10 or more years to assess the relationship between life-styles and cancer occurrence, and to evaluate the role of environmental exposures in the development of six major sites of cancers(stomach, liver, lung, colorectum, uterine cervix and female breast) in the rural population. Since 1993, 11,304 men and women aged over 35 living in four areas have been recruited. The number of target population is 30,000 persons, which is expected to be successfully recruited until 1999. Each subject has completed a detailed questionnaire on general life-styles, reproductive factors, and agricultural chemical exposures through the interview. Anthropometric measurements with body fat composition and the routine clinical laboratories were examined. For the cancer-free cohort, physical examination by the physicians and serologic tests for hepatitis markers, some tumor markers, and lipid profile have been done, but not all. In order to provide an opportunity to incorporate barious biomarkers of exposure and effect as well as genetic susceptibility, a biologic tissue bank has been established from blood and urine sample(plasma, WBC buffy-coat, RBC clots, and urine supernatant) stored at-70degrees C. Re-examination of changes in exposere to risk factors will be done periodically. Disease occurrence will be ascertained by the active(mainly through diagnosis by physicians) and the passive surveillance(through both death certificate and screening of medical utilization records).
