Abstract
We report a rare case of choledochal cyst (CC) associated with congenital duodenal atresia (DA) and annular pancreas (AP). A girl was born at 37 weeks of gestation weighing 2,974 g with a prenatal diagnosis of DA. She underwent a duodenoduodenostomy for type III DA with an AP 1 day after birth. At 4 years of age, she was admitted for evaluation of cholangitis and pancreatitis. Radiological studies demonstrated a fusiform-type CC with pancreaticobiliary maljunction (PBMJ). Excision of the CC and hepaticojejunostomy were performed. The patient was discharged without complications. Despite the fact that CC, DA, and AP are embryologically closely related entities, to the best of our knowledge, only eight such cases have been documented. We must be aware of the possible combination of CC in the follow-up of the patients with DA associated with AP.

Abstract
BACKGROUND The association between environmental tobacco smoking (ETS) and childhood pneumonia has not been established in developed or developing countries. A study was conducted to assess the effect and impact of ETS exposure on pneumonia among children in central Vietnam. METHODS A population-based large-scale cross-sectional survey was conducted covering all residents of 33 communes in Khanh Hoa Province, the central part of Vietnam. Information on demographics, socioeconomic status and house environment, including smoking status of each household member, was collected from householders. Hospital admissions for pneumonia among children aged <5 years in each household in the previous 12 months were recorded based on caregiver's report. RESULTS A total of 353 525 individuals living in 75 828 households were identified in the study areas. Of these, 24 781 (7.0%) were aged <5 years. The prevalence of ETS was 70.5% and the period prevalence of hospital admissions for pneumonia was 2.6%. Multiple logistic regression analysis showed that exposure to ETS was independently associated with hospital admissions for pneumonia (adjusted odds ratio 1.55, 95% CI 1.25 to 1.92). The prevalence of tobacco smoking was higher among men than women (51.5% vs 1.5%). It is estimated that 28.7% of childhood pneumonia in this community is attributable to ETS. CONCLUSIONS Children in Vietnam are exposed to substantial levels of ETS which results in 44 000 excess hospital admissions due to pneumonia each year among children aged <5 years.

Abstract
Tuberculosis, a potentially fatal infectious disease, affects millions of individuals annually worldwide. Human protective immunity that contains tuberculosis after infection has not been clearly defined. To gain insight into host genetic factors, nonparametric linkage analysis was performed using high-throughput microarray-based single nucleotide polymorphism (SNP) genotyping platform, a GeneChip array comprised 59 860 bi-allelic markers, in 93 Thai families with multiple siblings, 195 individuals affected with tuberculosis. Genotyping revealed a region on chromosome 5q showing suggestive evidence of linkage with tuberculosis (Z(lr) statistics=3.01, logarithm of odds (LOD) score=2.29, empirical P-value=0.0005), and two candidate regions on chromosomes 17p and 20p by an ordered subset analysis using minimum age at onset of tuberculosis as the covariate (maximum LOD score=2.57 and 3.33, permutation P-value=0.0187 and 0.0183, respectively). These results imply a new evidence of genetic risk factors for tuberculosis in the Asian population. The significance of these ordered subset results supports a clinicopathological concept that immunological impairment in the disease differs between young and old tuberculosis patients. The linkage information from a specific ethnicity may provide unique candidate regions for the identification of the susceptibility genes and further help elucidate the immunopathogenesis of tuberculosis.

Abstract
SETTING The National Tuberculosis Programme (NTP) in Cambodia, one of the countries most affected by tuberculosis (TB) and human immunodeficiency virus (HIV) infection in Asia. OBJECTIVE To conduct national HIV prevalence surveillance among TB patients, to estimate HIV prevalence among TB patients and to determine the potential of the NTP as a source for antiretroviral treatment (ART) scale-up. DESIGN Anonymous unlinked cross-sectional seroprevalence surveys including all TB patients registered by the NTP in January 2003 and January 2005. RESULTS HIV prevalence among all TB patients fell from 11.8% in 2003 to 9.9% in 2005 (P < 0.05). In 2003 and 2005, respectively 265 and 261 TB patients were identified as HIV-positive in a given month. Among new smear-positive pulmonary TB patients, the prevalence dropped from 8.2% to 5.2% (P < 0.01). CONCLUSION The two periodic surveys demonstrated a high prevalence of HIV among TB patients in Cambodia. However, the declining incidence of HIV from the late 1990s might now be reflected in the HIV prevalence among new smear-positive TB patients. The NTP is a potential source of ART if HIV counselling and testing are made more widely available to TB patients.

Abstract
BACKGROUND Several factors could influence patient satisfaction with endoscopy including technical quality of care, comfort and tolerability of the procedure, whether informed consent has been obtained, the level of communication with staff before and after the procedure, and delays in appointments. AIM To assess what factors should be measured in assessing patient satisfaction by using a 16-point questionnaire based on the informed consent recommendations of the first workshop at Kos, and of the criteria of the American Society for Gastrointestinal Endoscopy (ASGE), and to compare the response of patients with gastroenterologists and the support staff. METHOD The questionnaire was answered by 81 patients, 71 gastroenterologists and 36 support staff (nurses and receptionists). It graded the relative importance of different factors which influenced the perception of satisfaction in those undergoing endoscopy. These factors included: the waiting time for appointment, the explanation received at various stages before and after the procedure, the reception process, the importance of premedication against pain and discomfort, privacy and satisfaction related to findings at the procedure. RESULTS Thirteen of the 16 factors were generally graded as important for patient satisfaction. The finding at endoscopy, a written explanation and the alternatives to the endoscopic procedure were regarded as of lesser importance. Gastroenterologists tended to rate the importance of a written explanation and the explanations from the nurses before and after the procedure lower than did the patients and nursing staff. CONCLUSIONS The courtesy and personal manner of the entire medical staff, as evidenced by the explanation of the procedure by the various physicians before and after and the process of admission, were generally rated of the highest importance. The nurses' ranking of the various factors was closer to that of the patients than of the gastroenterologists.

Abstract
OBJECTIVE To investigate the epidemiology of dysmenorrhea in Japanese women of menstrual age. METHODS A prospective cohort study was conducted using a health diary in a sample representative of Japanese women. Information on health care use was also collected. RESULTS Among 823 enrolled participants (age range, 18-51 years), dysmenorrhea (mean duration 1.75 days; range 1-5 days) was reported in 15.8% (95% CI, 13.3-18.3) during the 1-month study period. Common associated symptoms included headache (10.77%), back pain (6.92%), and fatigue (5.38%). No participant with dysmenorrhea visited a physician, while 51.5% of the women used self-medication, and 7.7% used complementary/alternative medicine. CONCLUSION Dysmenorrhea is common in Japanese women. In our study, about half used self-medication, while some preferred complementary/alternative medicine. Dysmenorrhea is significantly associated with younger age and employment status.

Abstract
BACKGROUND Follicular lymphomas occasionally arise in the extra-nodal organs and are frequently found in the duodenum. They are often localised tumours with multiple polyps around the ampulla of Vater. AIMS To examine a IgH/bcl-2 hybrid gene and VH gene to investigate the nature of the lymphoma cells and how they differ from nodal follicular lymphomas and MALT lymphomas. METHODS Of 40 patients reported previously, 35 with duodenal follicular lymphoma were studied in detail with respect to clinicopathological characteristics. RESULTS 37/40 patients were in clinical stage I (n = 30) or stage II (n = 7). Clonal immunoglobulin gene rearrangement was detected in 53.3% of examined cases, and rearrangement of IgH/bcl-2 gene at the major break point was detected in 27% of cases. Three of 8 examined cases were VH4 (38%); 2 out of them were VH4-34. As VH4 deviation is one of the common characteristics of MALT lymphomas and 2/3 were identical, duodenal follicular lymphomas have a similar aetiology to MALT lymphomas. Clinical course was also similar to that of MALT lymphomas. CONCLUSIONS Results suggest that duodenal follicular lymphomas have intermediate characteristics of MALT lymphomas and nodal follicular lymphomas.

Abstract
BACKGROUND AND STUDY AIM Following acute diverticulitis, colonoscopy is advised to rule out malignancy. Commonly, the colonoscopy is postponed to avoid the potential risk of perforation. In a previous pilot, noncontrolled study, we showed that early colonoscopy is feasible in patients with acute diverticulitis. This randomized controlled trial compared early and late colonoscopy in hospitalized patients with acute diverticulitis. PATIENTS AND METHODS 154 patients diagnosed with acute diverticulitis were hospitalized between January 2004 and June 2006. Of these, 35 patients were excluded because of either free perforation or pericolic air on computed tomography (CT), and another 18 because they had undergone colonoscopy in the previous year. The remaining 101 patients were offered the possibility of participating in the study, with random allocation to either early in-hospital colonoscopy or late colonoscopy, 6 weeks later. Randomization was refused by 15 patients, and 86 were included in the study. RESULTS 45 patients were randomly allocated for early colonoscopy and 41 for late colonoscopy. Three and 10 did not present for the examination, in the early and late group respectively. The cecum could not be reached in eight and three patients from the early and late groups, respectively. The colonoscopy revealed polyps in five patients, two in the early group and three in the late group. No malignancy was detected. There were no complications in either group. CONCLUSIONS Early colonoscopy in acute diverticulitis is feasible and safe in the absence of pericolic air on CT, and has greater compliance. However, no added value is apparent compared with the CT scan currently used.

Abstract
OBJECTIVE To assess the prevalence of tuberculosis (TB) in Hanoi, Vietnam, in 2003/2004. METHODS A random selection was carried out involving 11624 subjects from 20 communes within the city. RESULTS On chest X-ray examination, 317 subjects (2.73%) showed abnormal lung opacity, of which 17 were sputum smear-positive, two concentrated smear-positive and three culture-positive, all with active TB. The prevalence of sputum smear-positive pulmonary TB was 146 per 100000 in persons aged >or=15 years (95%CI 65-228). CONCLUSION This is the first large-scale assessment of the prevalence of TB in Hanoi. The prevalence rate was higher than expected, suggesting that a significant number of patients with active TB, particularly females, remain undiagnosed, thus representing a continuing potential source of transmission in the community.

Abstract
The presence of receptor for chicken parathyroid hormone-related peptide (cPTHrP) in the cortical cells of the adrenal gland of the hen was demonstrated by radioligand binding assays. When the cortical cells were incubated in vitro with chicken adrenocorticotropic hormone (cACTH) in the presence of cPTHrP, greater production of corticosterone was observed than when incubated with cACTH alone. The results suggest that PTHrP may act directly on the adrenocortical cells via its receptor binding and increase the response to ACTH for corticosterone secretion in the hen.

Abstract
We report a case of light and heavy chain deposition disease (LHCDD), a rather rare monoclonal immunoglobulin deposition disease (MIDD) with successful therapeutic effect. A 58-year-old woman suffered from proteinuria and renal insufficiency (serum creatinine 1.0 mg/dl, creatinine clearance 49.2 ml/min) in February 2003. In serum and urine samples, monoclonal IgG-kappa was detected. A bone marrow aspiration showed a slightly hypocellular marrow and plasma cell population was increased to 7.0%. Renal histological findings revealed lobulated glomeruli with nodular lesions on light microscopy, characteristic findings of MIDD. Intense deposition of IgG heavy chains in the linear pattern in the glomerular and tubular basement membranes was observed. Immunohistochemistry revealed both kappa and lambda light chain depositions in glomeruli. Electron-microscopic examination revealed fine granular electron-dense deposits accompanied by microfibrils. Based on these findings, this patient was diagnosed as LHCDD. She received three courses of melphalan and prednisone chemotherapy, resulting in disappearance of proteinuria, prevention of renal functional deterioration and the decrease of monoclonal immunoglobulin. This case clearly demonstrates that the earlier and accurate diagnosis and initiation of chemotherapy at the early stage with serum creatinine level below 4.0 mg/dl are necessary to improve renal and patient outcome.

Abstract
We have searched for the decay B+-->omegal(+)nu (l=e or mu) in 78 fb(-1) of Upsilon(4S) data (85x10(6)BB events) accumulated with the Belle detector. The final state is fully reconstructed using the omega decay into pi(+)pi(-)pi(0), combined with detector hermeticity to estimate the neutrino momentum. A signal of 414+/-125 events is found in the data, corresponding to a branching fraction of (1.3+/-0.4+/-0.2+/-0.3)x10(-4), where the first two errors are statistical and systematic, respectively. The third error reflects the estimated form-factor uncertainty.
