Biliary ascariasis has been reported from many parts of the world but is common in Kashmir, India. We report five cases of biliary ascariasis of which four were the result of post-endoscopic sphincterotomy for choledocholithiasis. Therefore, biliary ascariasis is not an uncommon complication of endoscopic sphincterotomy.

Twenty-eight had undergone cholecystectomy, with choledocholithotomy in 11, and four had had miscellaneous operations. Endoscopic retrograde cholangiopancreatography (ERCP) was performed 2-75 days after operation and revealed leakage from the cystic duct stump in 19 cases, from a T tube track in five, from the gallbladder and liver abscess cavity in two and from the major bile ducts in six. Major bile duct lesions were not generally amenable to endoscopic treatment, but the remaining 26 patients were treated successfully with internal stenting (22) or endoscopic sphincterotomy (four); bile secretion in all cases stopped within 1 week. One patient with cholangitis after an ERCP procedure was managed by antibiotics; no other complication occurred and there were no deaths related to the procedure. ERCP procedures are well tolerated in the postoperative period and may be performed under sedation. ERCP is the method of choice for dealing with bile leakage and ERCP procedures are effective for the most common causes of postoperative bile leakage; complications are rare.

However, the pathogenesis of microlithiasis is not clear. The aim of this study was to determine the abnormalities of gallbladder emptying and bile composition in patients with microlithiasis. Nucleation time, cholesterol saturation index (CSI), and gallbladder emptying were studied in patients with microlithiasis (n = 10), patients with gallstones (n = 10), and healthy volunteers (n = 10). Bile analysis was repeated in 6 patients with microlithiasis treated with ursodeoxycholic acid (UDCA) for 8 weeks. Nucleation time was shorter in patients with microlithiasis and those with gallstones than in healthy volunteers (P < 0.0001). Patients with microlithiasis had longer nucleation time than those with gallstones (P < 0.001). There was no difference in cholesterol levels and CSI in gallstone and microlithiasis patients. However, healthy volunteers had lower cholesterol levels (P < 0.01) and CSI (P < 0.01). Patients with microlithiasis had prolongation of nucleation time (P < 0.001) and lowering of CSI (P < 0.001) after UDCA therapy. Gallbladder ejection fraction was higher in microlithiasis patients than in gallstone patients (P < 0.01) but lower than in healthy volunteers (P < 0.01). Patients with microlithiasis have longer nucleation time and better gallbladder emptying than patients with gallstones. Bile abnormalities can be successfully corrected with UDCA therapy in patients with microlithiasis.

Vaccination is the foremost tool for interrupting the HBV infection cycle. HBV vaccination was not included in India's government-sponsored expanded immunisation program until 2011, and many children born earlier remain unvaccinated. This study sought to observe the impact of the HOPE Initiative's school-based intervention to increase vaccination coverage by increasing HBV awareness among students in Lucknow, Uttar Pradesh. Methods: At 430 schools in the administrative areas within and surrounding Lucknow, students viewed an educational documentary film on HBV and completed two questionnaires, one immediately before the screening and the other six weeks later. Both questionnaires asked the same 14 questions, which were organized into five domains: knowledge of the magnitude of the problem of HBV; knowledge of modes of HBV transmission; knowledge of consequences of HBV infection; awareness of HBV; and attitudes regarding HBV. The baseline questionnaire also asked students whether they had been vaccinated against HBV. At two-year follow-up, researchers measured vaccination levels at a subset of 30 intervention schools and six non-intervention schools to further assess the impact of the intervention. Results: Baseline questionnaires were completed by 11,250 students, and post-intervention questionnaires, by 9698 students. Scores for knowledge about the magnitude of the HBV problem improved from 41% at baseline to 74% at follow-up, and scores for knowledge about modes of transmission, from 38% to 75% (p < 0.05 for both). The baseline HBV vaccination level among students receiving the intervention was 21%. Two years after the intervention, 45% of students (N = 4284) reported being vaccinated at intervention schools compared to 22% (N = 1264) at non-intervention schools. Conclusions: The observed increases in HBV awareness, knowledge and vaccination levels in this study indicate that school-based interventions can be used to achieve higher vaccination coverage among Indian children. The documentary film was found to be an affordable tool for reaching large audiences. More studies are needed to validate the impact of this intervention and to explore its applicability to other social causes.

We undertook the present study with two objectives: (i) to investigate the possible physiochemical and radiological differences between cholesterol gallstones obtained from Indian and German patients; and (ii) to compare the brittleness of the two stone groups. Forty Indian and 36 German gallstones (matched in size and shape) were subjected to assessment of physical characteristics, in vitro computed tomography (CT) and chemical analysis. German stones more often had a stone density distribution index of > or = 50 Hounsfield units (HU) (26 vs 14; P < 0.01), peripheral calcification (18 vs 9; P < 0.02), maximum CT density > or = 90 HU (17 vs 9; P < 0.05) and significant calcium carbonate (9 vs 5; P < 0.05), compared to Indian stones.

Seven patients with IPSID in two tertiary referral centers in India are included in the study. Diagnosis was based on typical clinical features [diarrhoea (7/7), weight loss (7/7), clubbing (6/7), fever (3/7), abdominal pain and lump (3/7)], biochemical evidence of malabsorption and duodenal biopsy findings. All patients were young males (mean age 29.8 +/- 11.8 years, range 17-53). Atypical features included gastric involvement (1/7), colonic involvement (1/7) and appearance of pigmented nails following anti-cancer chemotherapy (1/7) which disappeared six months after omitting doxorubin from chemotherapy regimen. Parasitic infestation was common. Ascaris lumbricoides (1/7), Giardia lamblia and hookworm (1/7), Strongyloides stercoralis and Trichuris trichura (1/7). In the latter patient S. stercoralis became disseminated after anti-malignant chemot...

Mutated p53 protein is more stable and gets accumulated in the cells that induce the host to develop anti-p53 antibodies in sera of cancer patients. This study is aimed to observe the frequency and nature of mutations in exons 5-8 of p53 gene and to evaluate its correlation with prevalence of serum p53 antibodies in Indian patients with gallbladder cancer (GBC). Mutation studies were done in cancer tissues obtained from 62 patients with proven GBC (40 cytologically proven cases and 22 resected gallbladder cancer tissues) by polymerase chain reaction (PCR), restriction fragment length analysis (RFLP) and single strand conformation polymorphism (SSCP). Presence of serum p53 antibodies was determined using highly specific enzyme linked immunosorbent assay (ELISA) kit in 50 patients with GBC and 30 patients of cholelithiasis. Clinicopathologic characteristics of these patien...

We evaluated effect of infusion of fat or placebo in duodenum randomly in patients with TS and healthy controls on antroduodenal manometry (ADM) and mediators of ileal brake, and duodenocaecal transit time (DCTT). ADM and DCTT (lactulose hydrogen breath test, HBT) were evaluated with placebo and fat in eight controls and 13 patients with TS (diagnostic criteria: tests showing malabsorption of two unrelated substances, abnormal duodenal histology, absence of other causes, response to antibiotics and folate). Patients with TS (6 had SIBO by glucose HBT) were similar in age and gender with controls. After fat infusion, proximal gut motility index (MI) was reduced compared to fasting state in TS, and DCTT was longer in TS than controls (200 min, 120-380 vs. 130, 70-160, P=0.001), though comparable after placebo (70 min, 30-140 vs. 60, 40-90). TS patients had higher PYY and...

We undertook the present study with two objectives: (i) to investigate the possible physicochemical and radiological differences beween cholesterol gallstones obtained from Indian and German patients; and (ii) to compare the brittleness of the two stone groups. Forty Indian and 36 German gallstones (matched in size and shape) were subjected to assessment of physical characteristics, in vitro computed tomography (CT) and chemical analysis. German stones more often had a stone density distribution index of 350 Hounsfield units (HU) (26 vs 14; P < 0.01), peripheral calcification (18 vs 9; P < 0.02), maximum C T density 3 90 HU (17 vs 9; P < 0.05) and significant calcium carbonate (9 vs 5; P < 0.05), compared to Indian stones. The in vitro lithotripsy performed with the Siemens Lithostar Plus machine at a constant energy level showed the German stones to be more brittle (easy to fragment), more often requiring < 1000 shocks for fragmentation (25/36; 69%) compared to Indian stones (1 8/40; 45'/0, P < 0.05). Gallstones from different geographic regions may show significant variations in their physicochemical characteristics that may explain the differences in their brittleness to lithotripsy.

We evaluated SIBO in NASH using quantitative jejunal aspirate culture (conventional criteria: ≥ 105 colony forming unit (CFU)/mL and newer cutoff ≥ 103 CFU/mL) and glucose hydrogen breath test. Thirty-eight patients with NASH (age 37.5 years, range 20-54, 9, 24% female), diagnosed by ultrasonography, alanine aminotransferase >1.5 times normal and liver biopsy (in 27/38, 71%) and exclusion of other causes and 12 constipation-predominant irritable bowel syndrome as historical controls (age 39.5-y, 26-44; 3, 25% female) without fatty liver were studied. Jejunal aspirates, obtained in 35/38 patients, were sterile in 14/35 (40%) and bacteria isolated in 21 (60%) (all aerobic, in one anaerobe also; Gram positive 5, negative 13, both 3). In contrast, bacteria (two Gram negative) were isolated in 3/12 (25%) controls (odds ...

A detailed literature search of published medical reports in English language was performed on electronic databases such as PubMed and Cochrane, from 2000 to 2016 using relevant search terms. The search yielded 25 relevant articles whose full texts were retrieved and evaluated. Non-alcoholic fatty liver disease (NAFLD) is an emerging cause of liver disease in India. It is observed that physicians under appreciate the overlap between NAFLD and metabolic risk factors, thus missing a significant proportion of high-risk NAFLD patients. Lifestyle intervention is generally considered the first line therapy for patients with NAFLD without steatohepatitis while pharmacotherapy (in addition to lifestyle intervention) is suggested for patients with non-alcoholic steatohep...

Twenty-eight had undergone cholecystectomy, with choledocholithotomy in 11, and four had had miscellaneous operations. Endoscopic retrograde cholangiopancreatography (ERCP) was performed 2-75 days after operation and revealed leakage from the cystic duct stump in 19 cases, from a T tube track in five, from the gallbladder and liver abscess cavity in two and from the major bile ducts in six. Major bile duct lesions were not generally amenable to endoscopic treatment, but the remaining 26 patients were treated successfully with internal stenting (22) or endoscopic sphincterotomy (four); bile secretion in all cases stopped within 1 week. One patient with cholangitis after an ERCP procedure was managed by antibiotics; no other complication occurred and there were no deaths related to the procedure. ERCP procedures are well tolerated in the postoperative period and may be performed under sedation. ERCP is the method of choice for dealing with bile leakage and ERCP procedures are effective for the most common causes of postoperative bile leakage; complications are rare.

However, the pathogenesis of microlithiasis is not clear. The aim of this study was to determine the abnormalities of gallbladder emptying and bile composition in patients with microlithiasis. Nucleation time, cholesterol saturation index (CSI), and gallbladder emptying were studied in patients with microlithiasis (n = 10), patients with gallstones (n = 10), and healthy volunteers (n = 10). Bile analysis was repeated in 6 patients with microlithiasis treated with ursodeoxycholic acid (UDCA) for 8 weeks. Nucleation time was shorter in patients with microlithiasis and those with gallstones than in healthy volunteers (P &amp;amp;amp;amp;lt; 0.0001). Patients with microlithiasis had longer nucleation time than those with gallstones (P &amp;amp;amp;amp;lt; 0.001). There was no difference in cholesterol levels and CSI in gallstone and microlithiasis patients. However, healthy volunteers had lower cholesterol levels (P &amp;amp;amp;amp;lt; 0.01) and CSI (P &amp;amp;amp;amp;lt; 0.01). Patients with microlithiasis had prolongation of nucleation time (P &amp;amp;amp;amp;lt; 0.001) and lowering of CSI (P &amp;amp;amp;amp;lt; 0.001) after UDCA therapy. Gallbladder ejection fraction was higher in microlithiasis patients than in gallstone patients (P &amp;amp;amp;amp;lt; 0.01) but lower than in healthy volunteers (P &amp;amp;amp;amp;lt; 0.01). Patients with microlithiasis have longer nucleation time and better gallbladder emptying than patients with gallstones. Bile abnormalities can be successfully corrected with UDCA therapy in patients with microlithiasis.

Vaccination is the foremost tool for interrupting the HBV infection cycle. HBV vaccination was not included in India's government-sponsored expanded immunisation program until 2011, and many children born earlier remain unvaccinated. This study sought to observe the impact of the HOPE Initiative's school-based intervention to increase vaccination coverage by increasing HBV awareness among students in Lucknow, Uttar Pradesh. Methods: At 430 schools in the administrative areas within and surrounding Lucknow, students viewed an educational documentary film on HBV and completed two questionnaires, one immediately before the screening and the other six weeks later. Both questionnaires asked the same 14 questions, which were organized into five domains: knowledge of the magnitude of the problem of HBV; knowledge of modes of HBV transmission; knowledge of consequences of HBV infection; awareness of HBV; and attitudes regarding HBV. The baseline questionnaire also asked students whether they had been vaccinated against HBV. At two-year follow-up, researchers measured vaccination levels at a subset of 30 intervention schools and six non-intervention schools to further assess the impact of the intervention. Results: Baseline questionnaires were completed by 11,250 students, and post-intervention questionnaires, by 9698 students. Scores for knowledge about the magnitude of the HBV problem improved from 41% at baseline to 74% at follow-up, and scores for knowledge about modes of transmission, from 38% to 75% (p < 0.05 for both). The baseline HBV vaccination level among students receiving the intervention was 21%. Two years after the intervention, 45% of students (N = 4284) reported being vaccinated at intervention schools compared to 22% (N = 1264) at non-intervention schools. Conclusions: The observed increases in HBV awareness, knowledge and vaccination levels in this study indicate that school-based interventions can be used to achieve higher vaccination coverage among Indian children. The documentary film was found to be an affordable tool for reaching large audiences. More studies are needed to validate the impact of this intervention and to explore its applicability to other social causes.

We undertook the present study with two objectives: (i) to investigate the possible physiochemical and radiological differences between cholesterol gallstones obtained from Indian and German patients; and (ii) to compare the brittleness of the two stone groups. Forty Indian and 36 German gallstones (matched in size and shape) were subjected to assessment of physical characteristics, in vitro computed tomography (CT) and chemical analysis. German stones more often had a stone density distribution index of > or = 50 Hounsfield units (HU) (26 vs 14; P < 0.01), peripheral calcification (18 vs 9; P < 0.02), maximum CT density > or = 90 HU (17 vs 9; P < 0.05) and significant calcium carbonate (9 vs 5; P < 0.05), compared to Indian stones.

Seven patients with IPSID in two tertiary referral centers in India are included in the study. Diagnosis was based on typical clinical features [diarrhoea (7/7), weight loss (7/7), clubbing (6/7), fever (3/7), abdominal pain and lump (3/7)], biochemical evidence of malabsorption and duodenal biopsy findings. All patients were young males (mean age 29.8 +/- 11.8 years, range 17-53). Atypical features included gastric involvement (1/7), colonic involvement (1/7) and appearance of pigmented nails following anti-cancer chemotherapy (1/7) which disappeared six months after omitting doxorubin from chemotherapy regimen. Parasitic infestation was common. Ascaris lumbricoides (1/7), Giardia lamblia and hookworm (1/7), Strongyloides stercoralis and Trichuris trichura (1/7). In the latter patient S. stercoralis became disseminated after anti-malignant chemot...

Mutated p53 protein is more stable and gets accumulated in the cells that induce the host to develop anti-p53 antibodies in sera of cancer patients. This study is aimed to observe the frequency and nature of mutations in exons 5-8 of p53 gene and to evaluate its correlation with prevalence of serum p53 antibodies in Indian patients with gallbladder cancer (GBC). Mutation studies were done in cancer tissues obtained from 62 patients with proven GBC (40 cytologically proven cases and 22 resected gallbladder cancer tissues) by polymerase chain reaction (PCR), restriction fragment length analysis (RFLP) and single strand conformation polymorphism (SSCP). Presence of serum p53 antibodies was determined using highly specific enzyme linked immunosorbent assay (ELISA) kit in 50 patients with GBC and 30 patients of cholelithiasis. Clinicopathologic characteristics of these patien...

We evaluated effect of infusion of fat or placebo in duodenum randomly in patients with TS and healthy controls on antroduodenal manometry (ADM) and mediators of ileal brake, and duodenocaecal transit time (DCTT). ADM and DCTT (lactulose hydrogen breath test, HBT) were evaluated with placebo and fat in eight controls and 13 patients with TS (diagnostic criteria: tests showing malabsorption of two unrelated substances, abnormal duodenal histology, absence of other causes, response to antibiotics and folate). Patients with TS (6 had SIBO by glucose HBT) were similar in age and gender with controls. After fat infusion, proximal gut motility index (MI) was reduced compared to fasting state in TS, and DCTT was longer in TS than controls (200 min, 120-380 vs. 130, 70-160, P=0.001), though comparable after placebo (70 min, 30-140 vs. 60, 40-90). TS patients had higher PYY and...

We undertook the present study with two objectives: (i) to investigate the possible physicochemical and radiological differences beween cholesterol gallstones obtained from Indian and German patients; and (ii) to compare the brittleness of the two stone groups. Forty Indian and 36 German gallstones (matched in size and shape) were subjected to assessment of physical characteristics, in vitro computed tomography (CT) and chemical analysis. German stones more often had a stone density distribution index of 350 Hounsfield units (HU) (26 vs 14; P < 0.01), peripheral calcification (18 vs 9; P < 0.02), maximum C T density 3 90 HU (17 vs 9; P < 0.05) and significant calcium carbonate (9 vs 5; P < 0.05), compared to Indian stones. The in vitro lithotripsy performed with the Siemens Lithostar Plus machine at a constant energy level showed the German stones to be more brittle (easy to fragment), more often requiring < 1000 shocks for fragmentation (25/36; 69%) compared to Indian stones (1 8/40; 45'/0, P < 0.05). Gallstones from different geographic regions may show significant variations in their physicochemical characteristics that may explain the differences in their brittleness to lithotripsy.

A detailed literature search of published medical reports in English language was performed on electronic databases such as PubMed and Cochrane, from 2000 to 2016 using relevant search terms. The search yielded 25 relevant articles whose full texts were retrieved and evaluated. Non-alcoholic fatty liver disease (NAFLD) is an emerging cause of liver disease in India. It is observed that physicians under appreciate the overlap between NAFLD and metabolic risk factors, thus missing a significant proportion of high-risk NAFLD patients. Lifestyle intervention is generally considered the first line therapy for patients with NAFLD without steatohepatitis while pharmacotherapy (in addition to lifestyle intervention) is suggested for patients with non-alcoholic steatohep...
