Abstract
PURPOSE Consensus is lacking regarding the optimal antibiotic treatment for pediatric complicated appendicitis. This study determined the optimal first-line antibiotic treatment for pediatric patients with complicated appendicitis based on peritoneal fluid cultures. METHODS This retrospective study examined the cases of pediatric patients who underwent appendectomy for complicated appendicitis at our institution between 2013 and 2019. Peritoneal fluid specimens obtained during appendectomy were cultured for the presence of bacteria. RESULTS Eighty-six pediatric patients were diagnosed with complicated appendicitis. Of them, bacteria were identified in 54 peritoneal fluid samples. The major identified bacteria were Escherichia coli (n=36 [66.7%]), Bacteroides fragilis (n=28 [51.9%]), α-Streptococcus (n=25 [46.3%]), Pseudomonas aeruginosa (n=10 [18.5%]), Enterococcus avium (n=9 [16.7%]), γ-Streptococcus (n=9 [16.7%]), and Klebsiella oxytoca (n=6 [11.1%]). An antibiotic susceptibility analysis showed E. coli was inhibited by sulbactam/ampicillin in 43.8% of cases versus cefmetazole in 100% of cases. Tazobactam/piperacillin and meropenem inhibited the growth of 96.9-100% of the major identified bacteria. E. coli (100% vs. 84.6%) and P. aeruginosa (100% vs. 80.0%) were more susceptible to amikacin than gentamicin. CONCLUSION Tazobactam/piperacillin or meropenem is a reasonable first-line antibiotic treatment for pediatric complicated appendicitis. In the case of aminoglycoside use, amikacin is recommended.

Abstract
PURPOSE To determine the features which predict torsion and the pre-operative indicators of malignancy in cases of ovarian torsion in ovarian tumors (OTs) in children. METHODS The medical records of 35 pediatric patients who underwent surgery for OT, except for neonate cases, from 1997 to 2018 at our institution were reviewed retrospectively. RESULTS The pathological diagnosis was mature teratoma in 17, immature teratoma in 9, yolk sac tumor in 3, and others in 6. The preoperative diagnosis, which was made based on the imaging findings and the serum tumor marker values, matched with the pathological diagnosis in 29/35 (83%). Ovarian torsion occurred in 14/35 (40%). All but one case that presented with torsion had intermittent abdominal pain as the primary symptom. The preoperative white blood cell count was significantly higher in cases where ovary preservation was impossible than where it was possible (p = 0.01) among the cases presenting with torsion. CONCLUSION Preoperative imaging findings and the serum tumor marker values enabled us to make an accurate preoperative diagnosis. Patients with intermittent abdominal primary symptoms were more likely to have ovarian torsion than those without such symptoms, and leukocytosis may indicate irreversible ischemic changes in the affected ovary.

Abstract
BACKGROUND Ovarian immature teratomas (ITs) are relatively rare among all pediatric ovarian tumors. The histological grading for ovarian ITs, which ranges from 1 to 3, is based on the proportion of immature neuroepithelial component. Higher-grade ITs in adults are treated as malignant neoplasms and require adjuvant chemotherapy. However, there is no consensus on the therapeutic management of pediatric ovarian ITs. The aim of our study was to analyze the histological grades and clinical characteristics of ovarian ITs in pediatric patients. METHODS This retrospective chart review consisted of seven patients, including one, three, and three patients with histological grade 1, 2, and 3 pediatric ovarian ITs, respectively, who were treated at our institute between 2000 and 2016. Collected data comprised age, alpha-fetoprotein (AFP) level, clinical stage, tumor size, treatment, and prognosis. RESULTS The median age and AFP levels of patients with grade 1, 2, and 3 ovarian ITs were 8, 7, and 10 years and 37, 112, and 221 ng/ml, respectively. All cases were Children Oncology Group (COG) stage I and International Federation of Gynecology and Obstetrics (FIGO) stage IA. All patients had unilateral tumors in the right ovary. The median tumor sizes of the grade 1, 2, and 3 IT patients were 104, 160, and 100 cm2, respectively. All patients underwent primary open surgery alone. Two patients, including one patient each with grade 2 and 3 ITs, underwent tumor enucleation as ovary-sparing surgery, whereas the remaining five patients underwent unilateral salpingo-oophorectomy. The median follow-up was seven years, and all cases achieved event-free survival. CONCLUSIONS Clinical characteristics of patients with grade 3 ovarian ITs were relatively older and had higher AFP levels than those with lower-grade ITs. According to our patient's clinical course and prognosis, COG stage I pediatric ITs should be treated by surgery alone and that postoperative chemotherapy is unnecessary even for those with grade 3 ITs as well as patients with rather low AFP levels.

Abstract
Although norovirus (NoV) is the major cause of gastroenteritis, with the largest number of NoV food poisoning cases in Japan, limited information is available regarding NoV detection in food. This study aimed to detect NoV in food samples during the 2015-2016 suspected foodborne outbreaks in Tokyo; 352 food samples from 64 NoV food poisoning outbreaks were collected. Bacterial culturing was performed for sample pretreatment and real-time reverse transcription polymerase chain reaction was conducted for NoV screening. The NoV detection rate was 1·7% (6/352). NoV-positive food samples included leftover boxed lunch, mackerel fillet (foodstuff), aburi salmon slice (partially seared salmon slice), raw tuna as a chirashizushi ingredient, raw amberjack as a sushi topping and ice for drinks. Since fresh fish as sushi toppings or ingredients and ice were consumed without heating, they may present a higher risk of viral infection. NoV-positive food samples were obtained from five outbreaks, wherein food handlers were NoV-positive in four. Each partial VP1 sequence from food samples matched completely with those in NoV-positive individuals and food handlers. Hence, food handlers play a potentially important role in food-based NoV transmission in all five outbreaks; therefore, hygiene education among them is essential to prevent NoV foodborne outbreaks. SIGNIFICANCE AND IMPACT OF THE STUDY: Significance and Impact of the Study: Norovirus (NoV) is a leading cause of foodborne outbreak in Japan. The most frequent route of transmission in NoV foodborne outbreaks is secondary contamination via infected food handlers. However, limited information is available regarding NoV contamination in food samples. This study reports the detection of NoV in food samples to elucidate the source and route of NoV infection leading to outbreaks for 2 years in Tokyo. Our data potentially contribute to education and the development of safe food-handling strategies among food handlers and employees in the food industry through elucidation of risk factors associated with NoV contamination.

Abstract
Aim To assess the feasibility of transferring to the University of Tsukuba Hospital for proton beam therapy (PBT) during intensive chemotherapy in children with Ewing sarcoma family of tumors (ESFT) who had been diagnosed and started their first-line treatment at prefectural or regional centers for pediatric oncology. Background The treatment of ESFT relies on a multidisciplinary approach using intensive neoadjuvant and adjuvant chemotherapies with surgery and radiotherapy. Multi-agent chemotherapy comprising vincristine, doxorubicin, cyclophosphamide, ifosfamide, and etoposide (VDC-IE) is widely used for ESFT, and the interval between each course is very important for maintaining the intensity and effect of chemotherapy. Materials and methods Clinical information of patients who received PBT and VDC-IE between April 2009 and May 2016 was collected retrospectively. The intervals between each course of VDC-IE and adverse events were assessed. Results Fifteen patients were evaluated. No delays in the intervals of chemotherapy due to transfer were observed. There were no adverse events caused during/just after transfer and no increases in adverse events. The estimated 4-year overall and event-free survival rates were 94.6% and 84.8%, respectively. Discussion Although the results of efficacy are preliminary, survival rates were comparable with past studies. More experience and follow-up are required to further assess the efficacy of PBT for patients with ESFT. Conclusion Multidisciplinary therapy for children with ESFT involving transfer to our hospital for PBT during VDC-IE was feasible without treatment delay or an increase in adverse events.

Abstract
Background Nonoperative management (NOM) has been established as the standard treatment for isolated blunt organ injury in hemodynamically stable pediatric patients. Although delayed splenic rupture or bleeding is a rare complication in NOM, it is an issue that many pediatric surgeons are greatly concerned about. We herein report a rare pediatric case concerning the mechanisms involved in delayed splenic rupture after NOM. Case presentation A 9-year-old boy with severe abdominal pain was transferred to our hospital. Twenty-one hours before the admission, he had been kicked in the region of his left lateral abdomen. Contrast-enhanced abdominal computed tomography revealed a severe intra-parenchymal hematoma and multiple lacerations of the spleen with a large amount of hemoperitoneum without active bleeding. His condition was diagnosed as a grade III injury on the AAST splenic injury scale. After fluid resuscitation, his vital signs became stable. The patient was treated with NOM in our intensive care unit. However, suddenly after defecation (72 h after the injury), he started complaining of severe abdominal pain and left shoulder pain. His blood pressure dropped to 70/35 mmHg, and he started to lose consciousness. Abdominal ultrasonography (US) revealed increased ascites. Fluid resuscitation and blood transfusion were performed. His symptoms and abdominal US findings suggested that splenic re-bleeding had caused delayed splenic rupture to occur. Emergency splenectomy was performed. The resected spleen was enlarged with a large parenchymal hematoma. The posterior-lateral side of the splenic capsule was ruptured. Conclusions The mechanism of delayed splenic rupture in our case was considered to be the result of a tear in the subcapsular hematoma caused by stretching the splenocolic ligament related to a bowel movement during defecation. Although delayed splenic rupture or bleeding is unpredictable, it is very important to understand the mechanisms and to educate the family of the children with splenic injuries of the warning signs of delayed rupture or bleeding.

Proton beams are able to avoid unnecessary irradiation to normal/vital organs. We conducted a quality of life (QOL) study for CCS who were treated with proton beam therapy (PBT). METHODS We included those patients treated with PBT to the brain, head, or neck and who were ≤15 years old at the University of Tsukuba Hospital between 1983 and 2011. Clinical information was collected from medical records. Questionnaires including the Pediatric Quality of Life Inventory (PedsQL) 4.0 Generic Core Scales (which assess health-related quality of life) were sent to the families/patients. RESULTS Sixty patients were included. Median age at treatment was 6.2 years. The number of patients with status alive/dead/unknown was 32/24/4. Median follow-up period was 63.0 months (range, 48-340 months) for survivors. Questionnaires were sent to 25 families/patients and 19 were returned. PedsQL was assessed for 17 patients. Eleven of 32 living patients had at least one comorbidity grade 3/4. Average QOL score was above that for Japanese schoolchildren and adolescents. There was no correlation with comorbidity, and only longer time from treatment was correlated with a higher PedsQL score (P = 0.006). CONCLUSION CCS who were treated with multimodal treatment using PBT had a higher QOL score. Higher score was related to longer time since treatment, regardless of comorbidity.

Abstract
BACKGROUND The aim of this study was to evaluate the outcome of an early discharge protocol for pediatric acute appendicitis. METHODS The present new early discharge protocol for appendicitis consisted of both postoperative early feeding and reduced-port laparoscopic surgery, to reduce surgical stress. The outcome was studied in patients with acute appendicitis treated at the present institution from 2012 to 2013. RESULTS Data on 36 acute appendicitis patients (mean age, 10.3 years) were collected. Operation time was 95 ± 27 min. Preoperatively, mean white blood cell (WBC) count was 13 850 ± 3644/μL; mean C-reactive protein (CRP), 2.7 ± 2.9 mg/dL; and mean procalcitonin, 0.25 ± 0.37 ng/mL. After surgery there was a significant decrease in WBC count, which fell to within the normal range; CRP peaked at 4.9 ± 3.2 mg/dL on postoperative day (POD) 1. On POD 7, all of the hematological markers were within the normal range. There were no postoperative complications. Mean hospital stay was 2.1 ± 1.1 days. Mean frequency of oral painkiller use was 3.2 ± 3.3 times per person. CONCLUSIONS The present early discharge protocol is safe and effective for the management of acute non-perforated appendicitis.

Abstract
Pulmonary interstitial emphysema (PIE) primarily affects premature infants on positive pressure ventilation. PIE is rarely reported in infants and children in the absence of mechanical ventilation and/or associated respiratory infection. We report a case of PIE in a 22-month-old girl who had severe respiratory distress due to respiratory syncytial virus infection. Chest computed tomography showed cystic lung lesions mimicking congenital cystic adenomatoid malformation. The cystic lesions spontaneously resolved after conservative treatment. Based on the clinical course and the chronological changes on imaging, the cystic lung lesions were diagnosed as localized persistent PIE.

Abstract
Background Hypergastrinemia and the resultant peptic ulcer related to an enteric duplication has been quite rarely reported in the literature. Case presentation We herein report the case of a 4-year-old girl who presented with hypergastrinemia and a duodenal ulcer at 2 years of age. She had been followed up with a proton pump inhibitor, which resulted in resolution of the ulcer; however, unexplained hypergastrinemia had continued. A cystic lesion at the antrum was discovered at 4 years of age, which we suspected to be a gastric duplication. After we resected the lesion, the hypergastrinemia resolved without recurrence of the duodenal ulcer. The histology was compatible with a gastric duplication, and the lumen was lined with antral mucosa that strongly stained positive for gastrin. We presumed that the antral mucosa inside the duplication in our case had no hydrogen ion feedback inhibition of gastrin release from gastrin cells and increased release of gastrin from the mucosa inside the duplication led to the duodenal ulcer. Only two cases have been reported in the literature that had hypergastrinemia related to enteric duplication. Conclusion Gastric duplication should be included in the differential diagnosis of sustained hypergastrinemia in children.

Abstract
PURPOSE Persistent pulmonary hypertension remains a major cause of mortality and morbidity in cases of congenital diaphragmatic hernia (CDH). Recently, RhoA/Rho-kinase-mediated vasoconstriction has been reported to be important in the pathogenesis of pulmonary hypertension (PH). Several recent reports have described that fasudil, a potent Rho-kinase inhibitor and vasodilator, could represent a potential therapeutic option for PH. We designed this study to investigate the hypothesis that the expression level of RhoA is increased in the nitrofen-induced CDH rat model. The expression level of Wnt11, an activator of RhoA, was also evaluated. METHODS Pregnant rats were treated with or without nitrofen on gestational day 9 (D9). Fetuses were sacrificed on D17, D19 and D21 and were divided into control and CDH groups. Quantitative real-time polymerase chain reaction was performed to determine the pulmonary gene expression levels of both Wnt11 and RhoA. An immunofluorescence study was also performed to evaluate the expression and localization of RhoA. RESULTS The relative mRNA expression levels of pulmonary Wnt11 and RhoA on D21 were significantly increased in the CDH group compared with the control group (p=0.016 and p=0.008, respectively). The immunofluorescence study confirmed the overexpression of RhoA in the pulmonary vessels of CDH rats on D21. CONCLUSIONS Our results provide evidence that the RhoA/Rho-kinase-mediated pathway is involved in the pathogenesis of PH in the nitrofen-induced CDH rat model. Our data also suggest that the fasudil, a Rho-kinase inhibitor, could represent a therapeutic option for the treatment of PH in CDH.

Abstract
Lipoblastoma, a relatively rare benign adipose neoplasm, predominantly affects children younger than 3 years of age. We herein report the case of a 7-month-old girl with an unusual myxomatous histology of lipoblastoma. A rapidly growing mass was detected in the subcutaneous area of the left buttock. Histologically, the tumor consisted of abundant myxoid stroma exhibiting cellular atypia and a high mitotic activity. Although the histological findings were unusual, the tumor was diagnosed as a lipoblastoma according to both PLAG1 immunohistochemistry and the presence of PLAG1 rearrangement on fluorescence in situ hybridization.

Abstract
Vitamin E deficiency induces neuronal dysfunction and while oxidative stress is likely to be involved in mediating this process, the detailed mechanisms remain to be elucidated. Previously, we found axonal degeneration in the hippocampal CA1 region in vitamin E-deficient mice of 6 months of age (long-term). However, 3 month-old (short-term) vitamin E-deficient mice did not exhibit axonal degeneration in same region. In order to characterize the mechanisms involved in axonal degeneration in long-term vitamin E-deficient mice, we examined changes in microtubule-related proteins. Long-term vitamin E-deficiency led to significantly increased expression of the phosphorylated form of collapsin response mediator protein (CRMP)-2 compared to short-term deficiency. It is well known that CRMP-2 plays a crucial role in the maintenance of neurite function. Similarly, long-term vitamin E-deficiency significantly decreased the expression of silent mating type information regulation (SIRT)-2 mRNA compared to short-term deficiency. SIRT-2 belongs to a family of class III histone deacetylases (HDACs) and functions in the deacetylation of tubulins. Furthermore, the expression of microtubule-associated protein light chain (MAP-LC)3-2, which is a key autophagy protein was significantly higher in the short-term vitamin E-deficiency than the long-term deficiency. These results indicate that the mechanisms of axonal injury in long-term vitamin E-deficient mice are related to dysfunction in microtubules assembly via alterations in microtubule-related proteins and autophagy.

Abstract
BACKGROUND This preplanned subset analysis of the phase III MONET1 study aimed to determine whether motesanib combined with carboplatin/paclitaxel (C/P) would result in improved overall survival (OS) versus chemotherapy alone, in a subset of Asian patients with nonsquamous nonsmall-cell lung cancer (NSCLC). PATIENTS AND METHODS Patients with nonsquamous NSCLC (stage IIIB/IV or recurrent) and no prior systemic therapy for advanced disease were randomized to IV carboplatin (AUC, 6 mg/ml min) and paclitaxel (200 mg/m2) for up to six 3-week cycles, plus either oral motesanib 125 mg q.d. or placebo. Primary end point was OS; secondary end points included progression-free survival (PFS), objective response rate (ORR), and safety. RESULTS Two hundred twenty-seven Asian patients from MONET1 were included in this descriptive analysis. Median OS was 20.9 months in the motesanib plus C/P arm and 14.5 months in the placebo plus C/P arm (P=0.0223); median PFS was 7.0 and 5.3 months, respectively, (P=0.0004); and ORR was 62% and 27%, respectively, (P<0.0001). Grade≥3 adverse events were more common in the motesanib plus C/P arm versus placebo plus C/P (79% versus 61%). CONCLUSION In this preplanned subset analysis of Asian patients with nonsquamous NSCLC, motesanib plus C/P significantly improved OS, PFS, and ORR versus placebo plus C/P. CLINICAL TRIAL NUMBER NCT00460317.

Abstract
The effects of cashew nut shell liquid (CNSL) feeding on methane production and rumen fermentation were investigated by repeatedly using 3 Holstein nonlactating cows with rumen fistulas. The cows were fed a concentrate and hay diet (6:4 ratio) for 4 wk (control period) followed by the same diet with a CNSL-containing pellet for the next 3 wk (CNSL period). Two trials were conducted using CNSL pellets blended with only silica (trial 1) or with several other ingredients (trial 2). Each pellet type was fed to cows to allow CNSL intake at 4 g/100 kg of body weight per day. Methane production was measured in a respiration chamber system, and energy balance, nutrient digestibility, and rumen microbial changes were monitored. Methane production per unit of dry matter intake decreased by 38.3 and 19.3% in CNSL feeding trials 1 and 2, respectively. Energy loss as methane emission decreased from 9.7 to 6.1% (trial 1) and from 8.4 to 7.0% (trial 2) with CNSL feeding, whereas the loss to feces (trial 1) and heat production (trial 2) increased. Retained energy did not differ between the control and CNSL periods. Digestibility of dry matter and gross energy decreased with CNSL feeding in trial 1, but did not differ in trial 2. Feeding CNSL caused a decrease in acetate and total short-chain fatty acid levels and an increase in propionate proportion in both trials. Relative copy number of methyl coenzyme-M reductase subunit A gene and its expression decreased with CNSL feeding. The relative abundance of fibrolytic or formate-producing species such as Ruminococcus flavefaciens, Butyrivibrio fibrisolvens, and Treponema bryantii decreased, but species related to propionate production, including Prevotella ruminicolla, Selenomonas ruminantium, Anaerovibrio lipolytica, and Succinivibrio dextrinosolvens, increased. If used in a suitable formulation, CNSL acts as a potent methane-inhibiting and propionate-enhancing agent through the alteration of rumen microbiota without adversely affecting feed digestibility.

Abstract
We report the case of 2-week-old female infant with cystic lung disease who presented with mild tachypnea and had no history of mechanical ventilation. Chest CT demonstrated multiple air-filled cystic lesions in right upper lobe, and the patient subsequently underwent a right upper lobectomy. Histology revealed cystic lesions located in the pulmonary parenchyma and showed that the lesions were lined by lymphatic endothelium and were communicating with dilated lymphatic vessels in the interstitium. Additionally, multinucleated foreign body giant cells were attached to the lumen of the cyst. On the basis of these findings, we considered this a case of persistent interstitial pulmonary emphysema (PIPE) with massive pneumatic expansion of the lymphatic vessels, resulting in cystic lesions with lymphatic endothelium in the pulmonary parenchyma. While PIPE is extremely rare in term non-ventilated infants, our case demonstrated that this disease should be added to the differential diagnosis of cystic lung diseases with lymphatic endothelium even in infants without mechanical ventilation. When cystic lesions and symptoms persist despite conservative treatment, open or thoracoscopic resection is an appropriate option for diagnosis and treatment.

Abstract
INTRODUCTION Smoking is a leading global cause of avoidable mortality. It has been reported that the nicotinic acetylcholine receptor (CHRNA4 and CHRNB2) genes might be associated with smoking behavior in several ethnic populations. However, no study between the 2 genes and nicotine dependence (ND) using a Japanese population has been reported. METHODS We examined the association between ND and 5 single nucleotide polymorphisms (SNPs) within the CHRNA4 and 3 SNPs within the CHRNB2 using a well characterized sample of 558 Japanese healthy male workers with a relatively homogeneous background. The Fagerström test for nicotine dependence (FTND) was used to quantify the degree of ND. Additionally, we explored the effect of gene-gene interactions of the 2 genes on ND. RESULTS We found CHRNB2 rs4845652 genotypes to be associated with FTND scores under an additive genetic model: rs4845652 T-allele carriers had lower ND levels (p=0.038; when adjusted for smoking duration: p=0.052). Furthermore, we demonstrated a possible gene-gene interaction of CHRNA4 and CHRNB2 on ND in a dose-dependent manner: those smokers with CHRNA4 rs1044397 GG or GA genotypes along with CHRNB2 rs4845652 CC genotype are likely to demonstrate higher ND scores. DISCUSSION These findings suggest that CHRNB2 rs4845652 T-allele carriers may be associated with lower levels of ND, and that certain allelic combinations of CHRNA4 and CHRNB2 might be correlated with higher ND levels. This preliminary study has certain limitations (issues such as sample size/power and multiple testing) that need to be taken into account, and the present work thus has an experimental nature.

Abstract
PURPOSE The aim of this study is to investigate the clinical characteristics of cases of duodenal atresia (DA) which present with bowel gas distal to a typical double-bubble sign through an anomalous bile duct conduit. METHODS Medical records of 57 neonates with duodenal obstruction (atresia or stenosis), presenting with a double-bubble sign and treated at our institute from 1978 to 2010, were retrospectively reviewed. RESULTS Thirteen (23%) of 57 neonates presented with bowel gas distal to the double-bubble sign. Passage of gas through the duodenal stenosis may have occurred in 3 cases, whereas in 9 cases, gas may have bypassed the atresia through an anomalous bifurcated bile duct termination and through the pancreatic duct from the accessory to the main pancreatic duct in one case. A preoperative upper gastrointestinal series was performed in 9 cases, and an anomalous bifurcated bile duct conduit was demonstrated in 5 cases. Severe and prolonged cholestasis necessitating evaluation for biliary atresia was found in 2 patients with anomalous bile duct anatomy. CONCLUSIONS Neonatal DA presenting with distal bowel gas via an anomalous bifurcated bile duct conduit is more common than initially thought and occurs more frequently than duodenal stenosis. These patients might be at risk for cholestasis, possibly owing to duodeno-biliary reflux through the ampulla.

Abstract
PURPOSE The aim of the study was to identify the clinical characteristics and outcome of patients with liver fibrosis in choledochal cyst (CC). METHODS Forty patients with CC who underwent liver biopsy were included. Liver fibrosis was classified as follows: grade 0, no fibrosis; grade 1, mild fibrosis localized in the portal area; grade 2, moderate fibrosis with occasional bridging; and grade 3, severe fibrosis with diffuse bridging. RESULTS Fourteen patients (35%) had liver fibrosis. Patients in the fibrosis group were significantly younger (1.2 vs 2.7 years) and had higher total bilirubin (5.3 vs 2.6 mg/dL). Severity of liver fibrosis was inversely correlated with age (P = .044). Amylase and lipase in bile were significantly lower in the fibrosis group (amylase, 531 vs 15,000 U/L; lipase, 783 vs 23,100 U/L). Postoperative serum analysis demonstrated no differences between the two groups. Most patients in both groups had normal aspartate aminotransferase, alanine aminotransferase, total bilirubin, and γ-glutamyl transpeptidase regardless of severity of fibrosis. Postoperative biliary complication or cholangiocarcinoma was not found in the fibrosis group. CONCLUSIONS Our data suggest that liver fibrosis is mainly influenced by obstructive cholangiopathy rather than refluxed pancreatic secretion. Prognosis of patients with CC and liver fibrosis was as good as that of patients without fibrosis.

Abstract
AIMS To determine the origins of DNA sequences isolated from the rumen microbial ecosystem using a self-organizing map (SOM). METHODS AND RESULTS DNA sequences other than 16S small subunit ribosomal RNA (SSU rRNA) gene sequences that were detected from the rumen were analysed by the SOM method reported by Abe et al. [2000, Self-Organizing Map (SOM) unveils and visualizes hidden sequence characteristics of a wide range of eukaryote genomes. Gene 365, 27-34]. Because query sequences positioned by SOM were scattered on the master drawing of SOM, it was suggested that many DNA sequences isolated from the rumen were collected from a broad range of micro-organisms. Although the results obtained by SOM were similar to those obtained by the neighbour-joining (NJ) method, SOM was able to presume the phylotypes of the query sequences without information about the 16S SSU rRNA gene sequences and homology searches, and to reveal existence of novel micro-organisms deduced to be cellulolytic bacteria, archaea and methanotrophic bacterium. CONCLUSIONS As the SOM method defined phylotypes of unreported rumen micro-organisms, it is presumed that these phylotypes would be involved in rumen fermentation in cooperation with known rumen micro-organisms. Moreover, it is demonstrated that SOM is a useful tool for affiliating DNA sequences, which have no matches in databases. SIGNIFICANCE AND IMPACT OF STUDY Through SOM analysis, a better means of identifying rumen micro-organisms and estimating their roles in rumen function was provided.

Abstract
e19021 Background: Few studies have formally assessed whether treatment outcomes for patients with extensive-disease small-cell lung cancer (ED-SCLC) enrolled in Phase III trials have improved substantially over the years. This investigation determined the trends in the outcomes for the patients in those trials. Methods: We analyzed trials that were reported between January 1991 and August 2008. Phase III randomized controlled trials were eligible if they compared first-line, systemic chemotherapy for ED-SCLC. Data were evaluated using linear regression analysis. Results: We identified 55 trials initiated between 1980 and 2006, involving 10,407 patients with 116 chemotherapy arms. The number of randomized patients and the proportions of patients with good performance status (PS) increased with the passage of time. In the 1990s, increasing numbers of studies examined cisplatin-based regimens, especially cisplatin and etoposide (PE) regimens, while decreasing numbers examined cyclophosphamide, doxorubicin, and vincristine-based regimens. A scattergram of the parameters ‘year of trial initiation’ and ‘median survival time’ (MST) indicated that MST increased 0.024 months (0.71 days) per year (P = 0.198). The multiple regression analysis showed no significant survival improvement over the years (regression coefficient for the year of trial initiation = 0.004, P = 0.980). In addition, the use of PE regimens did not prolong survival, whilst the proportion of good PS patients and the assignment of prophylactic cranial irradiation were significantly associated with favorable outcomes. Conclusions: The survival of patients with ED-SCLC enrolled in phase III trials has not improved significantly over the years, suggesting the need for a breakthrough, such as the discovery of novel molecular targets. No significant financial relationships to disclose.

Abstract
7699 Background: The AJCC disease stage, performance status (PS), and weight loss are established and important prognostic factors in patients with NSCLC. However, it is controversial whether smoking history affects the prognosis or not. We therefore assessed prognostic implication of smoking in patients with NSCLC. Methods: This retrospective study was performed using an institutional database for 1,440 NSCLC patients between 1995 and 2005. The characteristics of these patients were as follows: median age, 68 years (range,19–93); male/female, 947/493 patients; smokers/never-smokers, 897/543 patients; ECOG PS 0–1/2–4, 1319/121 patients; AJCC disease stage I-II/III-IV, 715/725 patients; squamous cell/non-squamous cell histologies, 391/1,049 patients; and weight loss > 5%/0–5%, 229/1,211 patients. Results: At a median follow-up time of 17 months (range, 1–59.7 months), the median survival time in smokers was 25 months, and significantly shorter than that in never-smokers (52 months, P < 0.0001). In a multivariate analysis using a Cox regression model, significance of the risk of death in smoking was confirmed when adjusted for age, sex, AJCC disease stage, ECOG PS, weight loss, and histologic subtypes (HR = 1.227, 95% CI 1.018–1.478, P = 0.032). Conclusions: Smoking history was considered to be a possible prognostic factor in patients with NSCLC. No significant financial relationships to disclose.
