Abstract
BACKGROUND Endometriosis is a disease among women of reproductive age, which causes several health problems, such as dysmenorrhea, dyspareunia, and subfertility. In addition, it increases psychological stress and often results in marital disharmony. Similarly, migraine is more frequent among this group of women. Several studies have shown an association between endometriosis and migraine among groups of populations completely different from Bangladesh. OBJECTIVE This study aimed to identify the association between endometriosis and migraine among the Bangladeshi population. STUDY DESIGN This nonrandomized case-control study was conducted with cases of endometriosis and controls without endometriosis who were confirmed by laparoscopy or laparotomy. Among the study participants, cases of migraine in 1 group of respondents who were already diagnosed as patients of migraine were identified, and the others with complaints of headaches were further confirmed by a medicine specialist. Patients were recruited from the Department of Obstetrics and Gynecology at the Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine and Metabolic Disorders General Hospital and Ibrahim Medical College. The study was approved by the ethical review committee of the Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine and Metabolic Disorders General Hospital. Multivariate logistic regression was used to identify the association between endometriosis and migraine using odds ratios and 95% confidence intervals. RESULTS Of 1496 patients who underwent laparoscopy or laparotomy during the study period, the frequency of endometriosis was found to be 12.7%. A total of 190 patients with confirmed endometriosis cases and an equal number of controls without endometriosis were enrolled, maintaining the age distribution of the controls similar to that of the cases. Compared with controls, the distribution of age, body mass index, education, and marital status of the patients with endometriosis were similar. The average ages of respondents were 30.6 years in both the case and control groups. Regarding occupation, cases included more students than controls (12% vs 0%, respectively). The odds of suffering from dysmenorrhea and dyspareunia among the cases were 3.3 (95% confidence interval, 2.66-4.15; P<.001) and 9.5 (95% confidence interval, 5.3-17.9; P<.001) times higher than that of controls, respectively. In addition, the odds of menstrual irregularity was 60% lower among the cases than among controls (odds ratio, 0.4; 95% confidence interval, 0.24-0.64; P<.001). No significant difference was observed in having primary subfertility and secondary subfertility among the 2 groups of respondents. Univariate regression analysis showed that patients with endometriosis have 6.13 times higher odds (95% confidence interval, 2.50-18.40; P<.001) of having a migraine and 2.00 times higher odds (95% confidence interval, 1.2-3.2; P=.01) of having a headache than controls. Furthermore, the age- and body mass index-adjusted multivariate model showed that patients with endometriosis have 5.4 times higher odds of having migraine than patients without endometriosis (95% confidence interval, 2.11-16.4; P<.001). In addition, the higher the age of reproductive-age women, the higher the odds of having migraine. A 1-year increase in age increases the odds of having migraine by 23% (odds ratio, 1.23; 95% confidence interval, 1.13-1.16; P<.001). CONCLUSION Our results support the association between endometriosis and migraine among the Bangladeshi population, which is similar to relevant studies conducted in other geographic locations. The groups of physicians who treat patients suffering from the 2 diseases, endometriosis and migraine, should keep this interrelationship in mind to ensure a better quality of life for the patient.

Abstract
Introduction: The objective of this study was to analyze longitudinal changes in sperm parameters of Bangladeshi men. We hypothesized that semen parameters declined for this population. Methods: We retrospectively analyzed semen data from men aged 18-64 years who sought care for general sperm quality or updates on fertility status at an infertility clinic in Dhaka, Bangladesh, from January 2000 to June 2016 (n = 13,953). Samples with incomplete data were excluded (n = 143). The WHO normal criteria and semen analysis procedures were used to evaluate parameters of the remaining 13,810 specimens. Samples with missing values on sperm concentration (n = 6187) were excluded from concentration analyses. Age and duration of abstinence at testing were recorded and adjusted for. Data were imported into SAS® 9.4 statistical software. Temporal significance was investigated using one-way ANOVA for motility parameters and Chi-square test for raw concentration. Logistic regression analyzed the effects of confounders on azoospermia and raw concentration, while median regression modeling adjusted confounders for concentration, total motility, and rapid linear (RL) motility. Results: Age distribution was significantly correlated with annual parameter changes (concentration, total motility, and RL motility [P < 0.0001]). Adjusted total motility and RL motility declined by 20% from their maximum values to end of the study (P < 0.0001). Raw concentration lacked clear trends and was unaffected by adjustment. Azoospermia increased by 18% between the 2000–2010 and 2011–2016 participants (odds ratio = 0.16 [0.14–0.16]). Conclusion: In agreement with the hypothesis, Bangladeshi males attending this clinic have experienced decline in semen parameters (total motility and RL motility) and increased frequency of azoospermia.

Abstract
Hb Tak is one of more than 200 high affinity haemoglobin variants reported worldwide. It results from the insertion of two nucleotides (AC) at the termination codon, between codon 146 and codon 147 of the beta-globin gene [Beta 147 (+AC)]. Polycythaemia is the main clinical feature although affected carriers are usually asymptomatic and do not require intervention. Several case studies in this region have reported the co-inheritance of Hb Tak with Hb E, delta beta and beta thalassaemia with one case of homozygous Hb Tak in a Thai boy. In this case report, a cluster of haemoglobin Tak was found in a family of Malay ethnic origin. Cascade family screening was conducted while investigating a 4-year old girl who presented with symptomatic polycythaemia. She had 2 previous Hb analysis done, at 7-month and 2-year-old with the diagnosis of possible Hb Q Thailand and Homozygous Hb D, respectively. Both diagnosis did not fit her clinical presentations. She was plethoric, had reduced exercise tolerance as well as cardiomyopathy. Her parents were consanguineously married and later diagnosed as asymptomatic carriers of Hb Tak. Consequently, re-analysis of the girl's blood sample revealed a homozygous state of Hb Tak. In conclusion, high oxygen affinity haemoglobin like Hb Tak should be considered in the investigation of polycythaemic patients with abnormal Hb analyses. In this case, DNA analysis was crucial in determining the correct diagnosis.

Abstract
BACKGROUND The availability of double-balloon enteroscopy (DBE) and small bowel capsule endoscopy (SBCE) in Ireland has revolutionised our approach to the diagnosis and treatment of small bowel disorders. AIMS To evaluate the use of DBE in Ireland and to compare the diagnostic yield with and without prior SBCE in order to improve the efficiency of our resources for small bowel endoscopy. METHODS A retrospective comparison study of all DBEs performed between two centres, one with SBCE available, was undertaken. Information was obtained by review of endoscopy reports, referral letters, radiology reports and charts. A review of the SBCE database was undertaken to identify patients who had undergone SBCE prior to DBE. RESULTS A total of 242 DBE procedures were carried out between both centres. SBCE was performed prior to DBE in 20 % (n = 46). The overall diagnostic yield of DBE was 47 % (n = 115). There was a statistically significant difference in diagnostic yield between the DBE only and the DBE with prior SBCE groups 44 versus 61 %, respectively, p < 0.0001. There was also a significant difference in the DBE approach, with 73 % of procedures being anterograde in centre 1 versus 56 % in centre 2. A subgroup analysis of centre 1 data revealed a negative predictive value of 100 % and a positive predictive value of 74 % for SBCE when DBE findings were considered as a gold standard. CONCLUSION SBCE as a screening tool prior to DBE is extremely valuable and increases the diagnostic yield considerably as a consequence of a high negative predictive value.

Abstract
BACKGROUND Prostate cancer (PrCa) is one of the most common cancers affecting men but its aetiology is poorly understood. Family history of PrCa, particularly at a young age, is a strong risk factor. There have been previous reports of increased PrCa risk in male BRCA1 mutation carriers in female breast cancer families, but there is a controversy as to whether this risk is substantiated. We sought to evaluate the role of germline BRCA1 mutations in PrCa predisposition by performing a candidate gene study in a large UK population sample set. METHODS We screened 913 cases aged 36–86 years for germline BRCA1 mutation, with the study enriched for cases with an early age of onset. We analysed the entire coding region of the BRCA1 gene using Sanger sequencing. Multiplex ligation-dependent probe amplification was also used to assess the frequency of large rearrangements in 460 cases. RESULTS We identified 4 deleterious mutations and 45 unclassified variants (UV). The frequency of deleterious BRCA1 mutation in this study is 0.45%; three of the mutation carriers were affected at age 65 years and one developed PrCa at 69 years. Using previously estimated population carrier frequencies, deleterious BRCA1 mutations confer a relative risk of PrCa of ~3.75-fold, (95% confidence interval 1.02–9.6) translating to a 8.6% cumulative risk by age 65. CONCLUSION This study shows evidence for an increased risk of PrCa in men who harbour germline mutations in BRCA1. This could have a significant impact on possible screening strategies and targeted treatments.

Abstract
OBJECTIVE The study was undertaken to compare the efficiency and outcome of Laparoscopic Assisted Vaginal Hysterectomy (LAVH) and Vaginal Hysterectomy (VH) in terms of operative time, cost, estimated blood loss, hospital stay, quantity of analgesia use, intra- and postoperative complication rates and patients recovery. MATERIALS AND METHODS A total of 500 diabetic patients were prospectively collected in the study period from January 2005 through January 2009. The performance of LAVH was compared with that of VH, in a tertiary care hospital. The procedures were performed by the same surgeon. RESULTS There was no significant difference in terms of age, parity, body weight or uterine weight. The mean estimated blood loss in LAVH was significantly lower when compared with the VH group (126.5±39.8 ml and 100±32.8 ml), respectively. As to postoperative pain, less diclofenac was required in the LAVH group compared to the VH group (70.38±13.45 mg and 75.18±16.45 mg), respectively. CONCLUSIONS LAVH, is clinically and economically comparable to VH, with patient benefits of less estimated blood loss, lower quantity of analgesia use, lower rate of intra- and postoperative complications, less postoperative pain, rapid patient recovery, and shorter hospital stay.

Abstract
Genome-wide association studies (GWAS) have identified more than 30 prostate cancer (PrCa) susceptibility loci. One of these (rs2735839) is located close to a plausible candidate susceptibility gene, KLK3, which encodes prostate-specific antigen (PSA). PSA is widely used as a biomarker for PrCa detection and disease monitoring. To refine the association between PrCa and variants in this region, we used genotyping data from a two-stage GWAS using samples from the UK and Australia, and the Cancer Genetic Markers of Susceptibility (CGEMS) study. Genotypes were imputed for 197 and 312 single nucleotide polymorphisms (SNPs) from HapMap2 and the 1000 Genome Project, respectively. The most significant association with PrCa was with a previously unidentified SNP, rs17632542 (combined P = 3.9 × 10−22). This association was confirmed by direct genotyping in three stages of the UK/Australian GWAS, involving 10,405 cases and 10,681 controls (combined P = 1.9 × 10−34). rs17632542 is also shown to be associated with PSA levels and it is a non-synonymous coding SNP (Ile179Thr) in KLK3. Using molecular dynamic simulation, we showed evidence that this variant has the potential to introduce alterations in the protein or affect RNA splicing. We propose that rs17632542 may directly influence PrCa risk.

Abstract
A 64-year-old woman was referred with a short history of abdominal pain, anorexia and weight loss. Investigations revealed a probable enteropathy associated T-cell lymphoma (EATL). Further investigations revealed evidence of what appeared to be a myocardial infarction. After going through laparoscopy to obtain diagnostic tissue, the patient developed cardiogenic shock which proved refractory to medical therapy. Postmortem examination revealed diffuse abdominal lymphoma consistent with EATL. Surprisingly, there was extensive infiltration of the myocardium. This report demonstrates an unusual pathology resulting from EATL and discusses the limited evidence relating to cardiac involvement of this disease.

Abstract
Hepatitis C virus-infected haemophiliacs are traditionally under represented in international treatment studies thus data assessing response to pegylated-interferon (peg-IFN) and ribavirin (RBV) in HCV mono-infected or HCV/HIV co-infected haemophiliacs are few. Since 2001, 37 haemophiliac patients have received peg-IFN and RBV according to centre-based investigator initiated protocols. Primary end points were: early virological response (EVR); end of treatment response (EOTR) and sustained virological response (SVR). An intention-to-treat analysis was used. Secondary end points were adverse events, haemopoietic stem cell growth factor use, therapy discontinuations and dose reductions. Hepatitis C virus mono-infection group (Mono-I) numbered 20 (60% genotype 1). HCV/HIV co-infected group (Co-I) numbered 17 (59% genotype 1/4). Primary end points were: EVR 76%, EOTR 70% and SVR 43%. Comparison of Mono-I to Co-I demonstrated: EVR rates of 70% and 82%, respectively; EOTR rates of 65% and 76%, respectively, and SVR rates of 35% and 53%, respectively. SVR rates genotype 1/4 group - 17% (Mono-I) vs. 30% (Co-I); SVR rates genotype 2/3 group - 63% (Mono-I) vs. 86% (Co-I). Therapy discontinuations: six of 20 (30%) Mono-I vs. three of 17 (18%) Co-I. Dose reductions: two of 20 (10%) Mono-I vs. zero of 17 Co-I. Haematological support factor use: one of 20 (5%) Mono-I vs. four of 17 (23.5%) Co-I. Virological outcomes to peg-IFN and RBV in HCV-infected haemophiliacs are comparable to published data relating to other HCV-infected cohorts. Good virological outcomes can be achieved in HIV co-infected haemophiliacs particularly when growth factors are used to facilitate full dosing of peg-IFN and RBV.

Abstract
Fludarabine was utilized in the conditioning regimen of 30 adult patients undergoing an allogeneic hematopoietic stem cell transplant. In 18 patients it was combined with full-dose busulfan (FluBu) as a myeloablative regimen and in 12 cases with melphalan (FluMel) as a reduced intensity conditioning (RIC) regimen. Patients in the FluBu group were younger than in the FluMel group (P=0.03). Of 30 patients, 24 received peripheral blood stem cells (PBSC) whereas six patients in the FluBu group received bone marrow cells. The hematological toxicity of each regimen was evaluated by analyzing the kinetics of the neutropenia induced by preparative regimens and the time to recovery of the absolute neutrophils count (ANC) and platelets post transplantation. In PBSC transplants, the median day of severe neutropenia (<500 ANC/microl) occurred on day +6 after the FluBu regimen and on day +3 after FluMel (P=ns), whereas both groups had a duration of severe neutropenia of 9 days and a comparable time for ANC and platelet engraftment. Extra-hematological toxicities were also comparable in the two groups. These findings suggest that the hematological and extra-hematological toxicities induced by fludarabine/full-dose i.v. busulfan are similar to those induced by a standard RIC regimen such as fludarabine/melphalan.

Abstract
Multiple myeloma (MM) has a double incidence in African-American (AA) than in non-AA patients and previous studies have shown a higher mortality in the former patient population. Here, we retrospectively analyzed the results of autologous stem cell transplantation (ASCT) in 38 AA and 32 non-AA consecutive patients. The two groups were comparable at diagnosis for age, stage of the disease, cytogenetic abnormalities, beta(2) microglobulin and albumin blood levels, and plasma cell marrow infiltration. The rates of complete and partial response observed in AA and non-AA patients after induction chemotherapy (9 and 42 vs 13 and 33%) and at 2 months (31 and 25 vs 30 and 20%) following ASCT were similar. At 6 months after ASCT, a greater relapse rate was observed in non-AA patients (P=0.009). At a median follow-up of 26 months, AA patients had a greater event-free survival (P=0.02) than non-AA patients, whereas overall survival was comparable in the two groups. The initial finding that AA patients with MM, compared to non-AA patients, had more prolonged responses and comparable survival after ASCT suggests that intensified chemotherapy is equally effective in patients of various ethnicities.

Abstract
Tissue transglutaminase (tTG) has recently been identified as the antigenic target recognised by anti-endomysial antibodies in patients with coeliac disease. In this study, an enzyme-linked immunosorbent assay (ELISA) is used to measure IgA, IgG and IgM antibodies to tTG in patients with coeliac disease and a variety of other inflammatory disorders; and is compared to the standard immunofluorescence test used to detect endomysial antibodies (EMA). In the samples tested, 3% control sera (n=146), 83% EMA-positive sera (n=29), 9% patients with Graves' disease (n=94), 12% antimitochondrial antibody-positive sera (n=53), 11% rheumatoid arthritis patients (n=53) and 22% systemic lupus erythematosus (SLE) patients (n=46) were positive for anti-tTG antibodies. In contrast, none of the controls, 1% of patients with Graves' disease, 2% antimitochondrial antibody-positive sera, 2% rheumatoid arthritis patients and none of the SLE patients were positive for EMA. Measurement of IgG or IgM antibodies to tTG was much less reliable than IgA anti-tTG antibody for the serological diagnosis of coeliac disease. The addition of calcium to the coating buffer improved the assay characteristics of the anti-tTG ELISA. However, the IgA anti-tTG ELISA, with and without calcium, performed less well than the standard EMA test used for the serological diagnosis of coeliac disease. In particular, the anti-tTG ELISA gave a higher rate of non-specific positive reactions.

Abstract
The alkaline single-cell gel electrophoresis or comet assay is a relatively simple method of measuring DNA single-strand breaks and alkali-labile sites in individual cells. Previously, we have used a combination of this with bromodeoxyuridine labelling of DNA and immunolocalisation of the BrdUrd to show that DNA replicative integrity can be assessed in single cultured cells. This study demonstrates the application of the technique to single cells derived from small human colonic biopsies isolated at routine endoscopy. A high level of reproducibility within replicate comet slides and between comet slides prepared from various colonic sites within a single patient is shown. Preliminary results demonstrate that defects in replication can be detected in tumour and premalignant colonic tissue adjacent to the tumour, suggesting that alterations in replicative integrity are an early event in neoplasia, appearing in premalignant mucosal cells. This development deems the BrdUrd comet assay suitable as an ex vivo molecular end point that can be measured easily in tissue collected by biopsy at routine colonic endoscopy. Thus, the BrdUrd comet assay has the potential to facilitate trial investigations of diet- or environment-related factors that may affect replicative integrity in the colon and provides a novel biomarker for colon carcinogenesis.

Abstract
The data on thyroid volume measurements that determines prevalence of goitre in children is very important for public health consideration as the presence of goitre in children effectively reflects the status of iodine deficiency disorders (IDD) in the general population. Ultrasound is an excellent modality to evaluate thyroid size. Local experience in using a portable ultrasound machine to measure thyroid volume is presented. The thyroid anatomy and techniques of ultrasound assessment are highlighted. Proper training of public health doctors to perform thyroid gland ultrasonography is crucial to ensure that the thyroid volume data collected would be more accurate and reliable for the planning of health programmes to eliminate IDD in the particular areas.

Abstract
BACKGROUND A number of cases of nephrotoxicity have been reported in patients with inflammatory bowel disease taking oral 5-aminosalicylic acid (5-ASA). AIM To evaluate the effects of 9 months of therapy with mesalazine or olsalazine on renal function in patients with ulcerative colitis in remission. METHODS Forty patients with ulcerative colitis in complete remission for 6 months were randomized to either olsalazine (n=20) or mesalazine (n=20 for nine months). Thirty-six of the 40 patients were on prior salicylate therapy. Disease activity was the measure ofclinical efficacy and was assessed by the Harvey-Bradshaw Index (HBI). Laboratory efficacy measurements included glomerular filtration rate (GFR), microalbuminuria, urinary gluthathione S-transferase (GST) and serum C-reactive protein (CRP). Safety analysis consisted of documentation of adverse events and laboratory values. RESULTS There was no significant reduction in the GFR overall on therapy. The levels of GFR adjusted for baseline were similar in the two treatment groups after 3, 6 and 9 months. A significantly higher percentage of mesalazine-treated patients experienced drug related adverse events, all of a minor nature. The incidence of adverse events causing early withdrawal was similar in the two treatment groups. CONCLUSION Treatment with mesalazine or olsalazine for 9 months had no significant impact on GFR.

Abstract
BACKGROUND Dyspepsia is a common symptom for which an organic cause is found in only 40% of patients. When no cause is apparent and the dyspepsia is considered to be idiopathic, a diagnosis of non-ulcer dyspepsia is made. The pathophysiology of non-ulcer dyspepsia is poorly understood and numerous theories have been put forward, including a theory of enhanced central serotoninergic receptor sensitivity. AIM To determine the sensitivity of serotonin receptors in non-ulcer dyspepsia. METHODS Using a randomized, double-blind, placebo-controlled design, we compared buspirone (a serotonin type 1a partial agonist)-stimulated prolactin release in 50 patients and 59 healthy comparison subjects. Buspirone, 30 mg, or matching placebo was administered on two separate occasions and prolactin release over 180 min was monitored. Patients and healthy subjects received both treatments in random order, 1 week apart. RESULTS Overall, patients with non-ulcer dyspepsia had greater prolactin release in response to the buspirone challenge than the healthy comparison subjects, with differences most significant at 90 min following the challenge. Enhancement occurred in patients both with and without Helicobacter pylori infection. Female subjects, both patients and healthy volunteers, showed a greater response to buspirone than male subjects, and the augmentation of response observed in male and female patients was greater in females. CONCLUSIONS Patients with non-ulcer dyspepsia have enhanced central serotoninergic responses and such responses are independent of H. pylori infection. Blockade of such receptors might be an appropriate therapeutic strategy.

Abstract
BACKGROUND AND AIMS The benefit of 5-aminosalicylic acid therapy for maintenance of remission in Crohn's disease is controversial. The primary aim of this study was to evaluate the prophylactic properties of olsalazine in comparison with placebo for maintenance of remission in quiescent Crohn's colitis and/or ileocolitis. METHODS In this randomised, double blind, parallel group study of olsalazine versus placebo, 328 patients with quiescent Crohn's colitis and/or ileocolitis were recruited. Treatment consisted of olsalazine 2.0 g daily or placebo for 52 weeks. The primary end point of efficacy was relapse, as defined by the Crohn's disease activity index (CDAI) and by clinical relapse. Laboratory and clinical disease activity indicators were also measured. Safety analysis consisted of documentation of adverse events and laboratory values. RESULTS No differences in the frequency of termination due to relapse or time to termination due to relapse were noted between the two treatment groups (olsalazine 48.5% v placebo 45%) for either colitis or ileocolitis. The failure rate, defined as not completing the study, was significantly higher in olsalazine treated patients compared with placebo treated patients for the overall population (colitis and/or ileocolitis: olsalazine 65.4% v 53.9%; p=0.038). Similar failure rates were seen for patients with colitis. A significantly higher percentage of olsalazine treated patients experienced adverse gastrointestinal events. Drug attributed adverse events were reported more frequently in the olsalazine treated group with gastrointestinal symptoms being causally related to olsalazine treatment (olsalazine 40.7% v placebo 26.9%; p=0.010). Back pain was reported significantly more often by the placebo treated group. However, serious medical events did not differ between the two groups. Adverse events led to more early withdrawals in the olsalazine treated group than in the placebo treated group; thus average time in the study for patients in the olsalazine treatment group was significantly shorter than that of patients in the placebo group. CONCLUSIONS Patients treated with olsalazine were more likely to terminate their participation in the trial than those taking placebo. This difference was not related to relapse of disease, as measured by CDAI and clinical measures, but rather was due to the development of intolerable adverse medical events of a non-serious nature related to the gastrointestinal tract. The gastrointestinal related events in the olsalazine treated group may be due to the difference in gastrointestinal status at baseline which favoured the placebo treatment group.

Abstract
Human mesenchymal stem cells (MSCs) are capable of differentiating into multiple mesenchymal lineages including chondrocytes, osteocytes, adipocytes, and marrow stromal cells. Using a nonhuman primate model, we evaluated nonhuman primate MSCs as targets for gene therapy. Baboon MSCs (bMSCs) cultured from bone marrow aspirates appeared as a homogeneous population of spindle-shaped cells. bMSCs were capable of differentiating into adipocytes and osteocytes in vitro and chondrocytes in vivo. bMSCs were genetically modified with a bicistronic vector encoding the human erythropoietin (hEPO) gene and the green fluorescent protein (GFP) gene. Transduction efficiencies ranged from 72 to 99% after incubation of MSCs with retroviral supernatant. Transduced cells produced from 1.83 x 10(5) to 7.12 x 10(5) mIU of hEPO per 10(6) cells per 24 hr in vitro before implantation. To determine the capacity of bMSCs to express hEPO in vivo, transduced bMSCs were injected intramuscularly in NOD/SCID mice. In a separate experiment, transduced bMSCs were loaded into immunoisolatory devices (IIDs) and surgically implanted into either autologous or allogeneic baboon recipients. Human EPO was detected in the serum of NOD/SCID mice for up to 28 days and in the serum of five baboons for between 9 and 137 days. NOD/SCID mice experienced sharp rises in hematocrit after intramuscular injection of hEPO-transduced bMSCs. The baboon that expressed hEPO for 137 days experienced a statistically significant (p < 0.04) rise in its hematocrit. These data demonstrate that nonhuman primate MSCs can be engineered to deliver a secreted and biologically active gene product. Therefore, human MSCs may be an effective target for future human gene therapy trials.

Abstract
BACKGROUND AND STUDY AIMS Endoscopic retrograde cholangiopancreatography (ERCP) has a significant mortality, morbidity, and failed cannulation rate. Magnetic resonance cholangiopancreatography (MRCP) is a safer, noninvasive method of imaging the pancreaticobiliary tree. A substantial number of patients are referred for ERCP because of abdominal pain, a high proportion of whom have normal ducts or pathology not requiring interventional ERCP. The aim was to assess the potential impact of MRCP on overall ERCP workload and patient outcome if MRCP were the primary investigation in patients referred for ERCP because of abdominal pain. PATIENTS AND METHODS 1758 consecutive ERCPs performed in 1148 patients over a 3-year period in a single tertiary referral center in the pre-MRCP era were reviewed. Cannulation failure, ERCP findings, need for follow-up ERCP and all 30-day major complication rates were analyzed with regard to clinical indications. RESULTS The overall workload comprised 1108 (63 %) successful initial ERCPs, 188 (11 %) failed cannulation attempts and 462 (26 %) follow-up ERCPs. Of the patients, 299 (27 %) had normal ERCP findings, 331 (30 %) had choledocholithiasis and 246 (22 %) had strictures. lf MRCP had been used as the primary imaging investigation in the 451 patients (39 %) referred for ERCP because of abdominal pain, we estimate that 197 patients (44 %) would have avoided ERCP, and the overall ERCP workload would have been reduced by 13 %. Initial MRCP in suspected gallstone pancreatitis and certain miscellaneous groups, it was estimated, would have further decreased ERCP workload by 9 %. Four of 40 major ERCP-related complications (3.5 %) and one of four ERCP-related deaths (0.35 %) would potentially have been avoided. CONCLUSIONS Initial MRCP in patients referred with abdominal pain would potentially have avoided ERCP in 44 % of cases, reduced ERCP workload by 13 % and significantly reduced patient morbidity and mortality. The relatively small reduction in ERCP workload among these patients reflects the fact that over half of them had probable sphincter dysfunction, a significant proportion of whom might have benefited from biliary manometry and/or endoscopic intervention despite a normal MRCP. Furthermore, a small number of patients with calculi and subtle biliary and pancreatic strictures would be missed by this approach.

Abstract
Nonhuman primates are useful large animal model systems for the in vivo study of hematopoietic stem cell biology. To better understand the degree of similarity of the hematopoietic systems between humans and baboons, and to explore the relevance of such studies in nonhuman primates to humans, this study was designed to compare the global gene expression profile of bone marrow CD34(+) cells isolated from these 2 species. Human complementary DNA (cDNA) filter arrays containing 25 920 human cDNAs were surveyed for this purpose. The expression pattern and relative gene abundance of the 2 RNA sources were similar, with a correlation coefficient of 0.87. A total of 15 970 of these cDNAs were expressed in human CD34(+) cells, of which the majority (96%) varied less than 3-fold in their relative level of expression between human and baboon. Reverse transcriptase-polymerase chain reaction analysis of selected genes confirmed that expression was comparable between the 2 species. No species-restricted transcripts have been identified, further reinforcing the high degree of similarity between the 2 populations. A subset of 1554 cDNAs, which are expressed at levels 100-fold and greater than background, is described, which includes 959 expressed sequence tags and uncharacterized cDNAs, and 595 named genes, including many that are clearly involved in hematopoiesis. The cDNAs reported here represent a selection of some of the most highly abundant genes in hematopoietic cells and provide a starting point to develop a profile of the transcriptosome of CD34(+) cells.

Abstract
BACKGROUND Most large published series on endoscopic retrograde cholangiopancreatography (ERCP) are multicentre-based and consequently reflect varying experience. AIMS To assess morbidity and mortality rates of ERCP in a single tertiary referral centre. METHODS A series of 1,758 consecutive ERCPs performed in 1,148 patients between 1991 and 1994 were reviewed to evaluate indications, findings, procedures, success, complication and mortality rates. RESULTS There were 1,108 (63%) successful initial ERCPs, 11% failed cannulation attempts and 26% follow-up ERCPs. The desired duct was successfully cannulated in 96.5% of cases. Initial cannulation failure rate was 8.8%. Twenty-seven per cent had normal ERCPs, 30% had choledocholithiasis and 22% had strictures. Fifty-five per cent had therapeutic ERCPs. Major complications occurred in 3.5% with four ERCP-related deaths (0.35%). Therapeutic ERCP had a higher incidence of major complications compared to diagnostic ERCP: 4.6% vs 2.1%, (p=0.02); and mortality rate was 0.5% vs 0.2%, (p=0.4). Significant haemorrhage secondary to biliary sphincterotomy, pre-cut papillotomy and snare papillectomy accounted for most of the difference (1.6%). CONCLUSIONS The majority of ERCPs were performed in elderly patients, over half of whom required therapeutic ERCP. Therapeutic ERCP carried significantly higher complication rate compared with diagnostic ERCP. Unsuccessful cannulation and follow-up ERCP accounted for 11% and 26% of ERCP workload, respectively.

Abstract
Quiescence has been thought to be required for the retention of the full biological potential of pluripotent hematopoietic stem cells (PHSCs). This hypothesis has been challenged recently by the observation that all murine PHSCs cycle continuously and constantly contribute to steady-state blood cell production. It was asked whether these observations could be extrapolated to describe hematopoiesis in higher mammals. In this series of experiments, the replicative history of PHSCs was examined in baboons by continuously administering bromodeoxyuridine (BrdU) for more than 85 weeks. The results indicate that under steady-state conditions, PHSCs remain largely quiescent but do cycle, albeit at a far lower rate than previously reported for rodent PHSCs. BrdU-labeled cycling PHSCs and progenitor cells were shown to have an extensive proliferative capacity and to contribute to blood cell production for prolonged periods of time. The proportion of PHSCs entering cell cycle could, however, be rapidly increased by the in vivo administration of granulocyte-colony stimulating factor. These data indicate that during steady-state hematopoiesis, baboon PHSCs require prolonged periods of time to cycle and that the proportion of PHSCs in cycle is not fixed but can be altered by external stimuli. The relative quiescence of PHSCs observed in this nonhuman primate model, in contrast to murine PHSCs, might explain the current barriers to genetic modification and ex vivo expansion of human PHSCs.

Abstract
BACKGROUND Soluble adhesion molecules are elevated in a number of inflammatory conditions. AIMS To investigate the correlation of soluble intercellular adhesion molecule-1 (sICAM-1) and sE-selectin with the activity of inflammatory bowel disease (IBD). METHODS sICAM-1 and sE-selectin were measured by an enzyme-linked immunosorbent assay (ELISA) in 53 patients with ulcerative colitis (UC) and 38 patients with Crohn's disease (CD). RESULTS Patients with active UC and CD had significantly higher sICAM-1 than patients with inactive disease and controls. Patients with pancolitis had significantly higher levels than patients with distal colitis. There was a significant difference in sE-selectin levels between patients with active CD and control sICAM-1. sE-selectin did not correlate with the Harvey Bradshaw index (HBI). C-reactive protein (CRP) and microalbuminuria were better markers than sICAM-1 or sE-selectin which correlated with serum tumour necrosis factor (TNF)-alpha. CONCLUSION sICAM-1 and sE-selectin are elevated in the serum of patients with IBD but CRP and microalbuminuria reflect clinical disease activity more accurately. This study does not support the routine use of soluble adhesion molecules as disease activity markers in IBD.

Abstract
BACKGROUND Nitric oxide (NO) production is increased in inflammatory bowel disease (IBD), and measurement of NO metabolites may be useful for monitoring disease activity. AIMS AND OBJECTIVES To characterise urinary nitrite levels, a stable metabolite of NO, in IBD and to evaluate its potential as a marker of disease activity. METHODS Twelve-hour urinary nitrites were measured by the microplate assay method in 46 patients with IBD (active; n = 32). Urinary samples from 16 healthy individuals served as controls. RESULTS Increased levels of urinary nitrites were found in patients with active IBD compared with those with inactive IBD. Twenty-eight out of 32 patients (87.5%) with active IBD had detectable levels of nitrite in their urine as compared with 2/14 (14.3%) patients with inactive IBD. None of the 16 healthy controls had detectable urinary nitrite. Twelve-hour urinary nitrite in active compared with inactive IBD: 5 0.7 versus 0.1+/-0.04 micromol (P < 0.05). There was good correlation between urinary nitrite and some markers of disease activity in IBD such as C-reactive protein and microalbuminuria but not with erythrocyte sedimentation rate. CONCLUSIONS Increased levels of nitrite were detected in urine of patients with active IBD, consistent with increased NO synthesis. This simple assay may be exploited as a potential marker of disease activity in IBD.
