ABSTRACT
BACKGROUND AND AIM: Patients with functional dyspepsia (FD) often have concomitant anxiety and depression. Mindfulness-based cognitive therapy (MBCT) combines the principles of cognitive behavioral therapy and mindfulness. It is a group-based therapy and has been shown to be efficacious in functional gastrointestinal disorders. There are no randomized controlled trials (RCTs) evaluating MBCT in FD. We aimed to evaluate feasibility and efficacy of MBCT in FD management. METHODS: We performed a mixed-method single-center pilot randomized trial of 28 patients fulfilling ROME-III criteria for FD. Fifteen patients were randomized to an 8-week MBCT program while 13 underwent treatment-as-usual (TAU). Patients completed questionnaires at baseline and at week 8. Two focus-groups were conducted. Feasibility of recruitment, acceptability of randomization, procedures and intervention, handout compliance and feasibility of quantitative measures were assessed. The primary outcome was subjective-clinical-assessment of FD symptoms (SCA-FD). Secondary outcome measures included Short-form Nepean Dyspepsia Index (SF-NDI), subjective-clinical-assessment of general health (SCA-GH), EuroQoL-Visual Analog Scale (EuroQoL-VAS), and Depression, Anxiety and Stress Scale-21 Items (DASS-21). RESULTS: Twelve of 15 patients in the MBCT group completed the program. There was a trend towards symptom improvement, with 90% in the MBCT group reporting improvement in SCA-FD compared with 45% in TAU(P = 0.063). Patients who underwent MBCT reported greater improvement in SF-NDI (mean change: -8.8 (SD: 7.5) vs -0.7 (7.2), P = 0.018) and DASS-21 (-19.8 (29.5) vs -5.5 (6.6) P = 0.13) compared with TAU. There was no difference in SCA-GH and EuroQoL-VAS. Based on SCA-FD improvement, the eventual RCT will require 50 patients (25 in each group). CONCLUSIONS: Mindfulness-based cognitive therapy is likely efficacious for FD, and it would be feasible to conduct a RCT.

BACKGROUND AND AIM: Brush cytology, the conventional method to diagnose cholangiocarcinoma, has been plagued by low diagnostic sensitivity and false-negative results. This paper aims to study the clinical utility of fluorescence in situ hybridization (FISH) in enhancing identification of malignant biliary strictures. METHODS: Brush cytologic specimens collected from endoscopic retrograde cholangiopancreatography for biliary strictures in a tertiary hospital in Singapore from March 2013 to July 2015 were examined by FISH technique using UroVysion probe set in this study. RESULTS: Thirty patients were chosen with five patients having multiple FISH performed due to indeterminate results. The diagnoses for biliary strictures were 13 (43.3%) cholangiocarcinomas, seven (23.3%) pancreatic cancers, seven (23.3%) benign biliary strictures, and three (10%) primary sclerosing cholangitis. Conventional brush cytology had sensitivity of 53.8% with specificity of 82.4%. FISH had sensitivity of 30.8% with specificity of 100%. When FISH results were interpreted in cases with negative or atypical brush cytology, two patients had positive FISH results and cholangiocarcinomas. Based on this pilot study, FISH increased sensitivity of brush cytology in detection of cholangiocarcinoma from 53.8% to 69.2% while preserving specificity of 82.4%. CONCLUSION: Compared with conventional cytology with low sensitivity, FISH may help to increase sensitivity on top of brush cytology while maintaining high specificity.

INTRODUCTION: Patients with functional gastrointestinal disorders (FGIDs) have a decreased quality of life (QoL). Psychological illnesses are strongly associated with FGIDs. This study examined the effect of a comprehensive psychological intervention programme designed for refractory FGID patients. METHODS: Refractory FGID patients at a tertiary gastroenterology unit were encouraged to participate in a psychological intervention programme, which included screening for anxiety and depression in patients, educating patients and physicians on FGIDs, and providing early access to psychiatric consultation for patients with significant psychological illnesses. The duration of follow-up was six months. Outcomes were measured using the Irritable Bowel Syndrome-QoL (IBS-QoL) instrument and the EuroQol five dimensions (EQ-5D) questionnaire. RESULTS: A total of 1,189 patients (68% female, 80% Chinese, mean age 48.6 years) participated in the programme. Among these participants, 51% had a significant psychological disorder (Hospital Anxiety and Depression Scale [HADS] anxiety or depression score > 7). These participants had a significantly poorer QoL (IBS-QoL and EQ-5D, both p < 0.0001), and were more likely to be single or English-speaking, as compared to the participants without psychological disorders. Participants who completed ≥ 3 months of follow-up (n = 906) showed significant and durable improvement. High baseline HADS anxiety score predicted improvement (p < 0.001), with participant IBS-QoL and EQ-5D scores decreasing over time. CONCLUSION: The intervention programme was associated with a clinically meaningful improvement in the QoL of patients with refractory FGIDs. High baseline anxiety was predictive of improvement.

Background. Paraneoplastic syndromes (PNS) such as hypercalcaemia, hypercholesterolaemia, and erythrocytosis have been described in hepatocellular carcinoma (HCC). Aims. (1) To examine the prevalence, clinical characteristics, and survival of PNS in HCC patients and (2) to evaluate the extent to which each individual PNS impacts on patient survival. Methods. We prospectively evaluated the prevalence, clinical characteristics, and survival of PNS among 457 consecutive HCC patients seen in our department over a 10-year period and compared them with HCC patients without PNS. Results. PNS were present in 127 patients (27.8%). The prevalence of paraneoplastic hypercholesterolemia, hypercalcemia, and erythrocytosis 24.5%, 5.3%, and 3.9%, respectively. Patients with PNS had significantly higher alpha-fetoprotein levels, more advanced TNM stage, and shorter survival. Among the individual PNS, hypercalcemia and hypercholesterolemia were associated with more advanced disease and reduced survival but not erythrocytosis. On multivariate analysis, the presence of PNS was not found to be an independent prognostic factor for reduced HCC survival. Conclusion. PNS are not uncommon in HCC and are associated with poor prognosis and reduced survival due to their association with increased tumor burden. However, they do not independently predict poor survival. Individual PNS impact differently on HCC outcome; paraneoplastic hypercalcemia in particular is associated with poor outcome.
ABSTRACT
BACKGROUND: Hepatocellular carcinoma (HCC) is uncommon in young adults. This study examined the clinical characteristics and survival outcome of young HCC patients compared with those in older patients. METHODS: Data were prospectively collected from 638 patients diagnosed with HCC over a 9-year period. Patients aged < or =40 years at diagnosis of HCC were defined as young HCC patients. Their clinical characteristics and survival was compared with those aged >40 years. RESULTS: The prevalence of young HCC was 8.6% (55/638). Young HCC patients had a significantly higher rate of hepatitis B-related disease (HBsAg positivity: 85.5% vs. 59.7%, P = 0.003), better Child-Pugh status (Child-Pugh class A: 69.1% vs. 43.9%, P = 0.002), and lower rates of cirrhosis (12.7% vs. 34.3%, P = 0.001) compared with the older group. They had more advanced disease at diagnosis, with higher alpha-fetoprotein levels (>12 000 microg/l: 45.4% vs. 30.5%, P = 0.026), a higher incidence of portal vein involvement (63.6% vs. 40%, P = 0.003), and a more advanced TNM stage (TNM IV: 83.6% vs. 66.4%, P = 0.018). More young patients were eligible for surgical resection (18.2% vs. 8.2%, P = 0.014). The overall survival between the two groups was similar, but when the patients were stratified for stage of disease, the median survival of young patients with early disease was superior to that of older patients (51.2 vs. 11.6 months, P = 0.025). CONCLUSIONS: HCC in young adults occurs mainly in hepatitis B carriers and is often diagnosed at an advanced stage. Their survival outcome is not different from that of older patients because the advanced disease at presentation offsets the advantages of better liver function and a higher resection rate. However, there is a distinct survival advantage for young patients diagnosed with early disease. These results support the importance of extending HCC surveillance to young hepatitis B carriers.

BACKGROUND AND AIM: Extracorporeal shockwave lithotripsy (ESWL) has an established role in the management of pancreatic ductal stones. Its efficacy in management of multiple stones in tropical pancreatitis is unknown. The aim of this study was to prospectively evaluate: (i) the efficacy of main pancreatic duct stone clearance; and (ii) associated complications with ESWL therapy in tropical pancreatitis. METHODS: Consecutively recruited patients with tropical pancreatitis underwent fragmentation of main pancreatic duct stones using ESWL. Endoscopic retrograde cholangiopancreatography (ERCP) using standard techniques was performed to manage residual stones. Complete, partial and unsatisfactory clearance was defined as >90%, 50-90% and <50% of stone clearance, respectively. Clinical and technical data were collected on a pre-formatted data sheet. Statistical analysis was performed on an intention-to-treat basis. RESULTS: A total of 250 patients (mean+/-SD age 35.2+/-11.9 years; 66% men), 86.8% with multiple radio-opaque stones, underwent ESWL between February 2004 and May 2005. Of the 250 patients, 149 (59.6%) achieved complete clearance and 59 (23.6%) achieved partial clearance of pancreatic calculi. Main pancreatic ductal decompression was achieved in 70.0% (175/250) of patients. Complications occurred in 5.6% (14/250) during ESWL and in 1.2% (3/250) during ERCP. A mean of 1.3 sessions, with mean+/-SD 5.5+/-0.7 intensity setting, 85.8+/-13.5 pulses per minute and 3862+/-1426 shocks per session were required. CONCLUSION: Clearance of multiple main pancreatic duct stones in patients with tropical pancreatitis is safely performed via ESWL followed by ERCP ductal drainage.
