Abstract
Infection with the hepatitis E virus (HEV) causes a self-limiting acute hepatitis. However, prolonged viremia and chronic hepatitis has been reported in organ transplant recipients. Vertically transmitted HEV infection is known to cause acute hepatitis in newborn babies. The clinical course and duration of viremia in vertically transmitted HEV infection in neonates in not known. We studied 19 babies born to HEV infected mothers. Babies were studied at birth and on a monthly basis to evaluate clinical profile, pattern of antibody response and duration of viremia in those infected with HEV. Fifteen (78.9%) babies had evidence of vertically transmitted HEV infection at birth (IgM anti-HEV positive in 12 and HEV RNA reactive in 10) and three had short-lasting IgG anti-HEV positivity because of trans-placental antibody transmission. Seven HEV-infected babies had icteric hepatitis, five had anicteric hepatitis and three had high serum bilirubin with normal liver enzymes. Seven babies died in first week of birth (prematurity 1, icteric HEV 3, anicteric HEV 2 and hyperbilirubinemia 1). Nine babies survived and were followed up for clinical, biochemical, serological course and duration of viremia. Five of 9 babies who survived were HEV RNA positive. HEV RNA was not detectable by 4 weeks of birth in three babies, by 8 weeks in one and by 32 weeks in one. All surviving babies had self-limiting disease and none had prolonged viremia. Thus HEV infection is commonly transmitted from mother-to-foetus and causes high neonatal mortality. HEV infection in survivors is self-limiting with short lasting viremia.

Abstract
BACKGROUND The treatment effects of primary prophylactic endoscopic variceal ligation are unclear. AIM To compare the treatment effects of endoscopic variceal ligation and beta-blockers for primary prophylaxis of oesophageal variceal bleeding. In addition, a subgroup analysis was done with the purpose to delineate differences in the effects of intervention that were biologically based. METHODS We performed a literature search for randomized controlled trials, which compared the treatment effects of endoscopic variceal ligation with beta-blockers for primary prophylaxis of oesophageal variceal bleeding. Of the 955 articles screened, eight randomized-controlled trials including 596 subjects (285 with endoscopic variceal ligation and 311 with beta-blockers) were analysed. Outcomes measures evaluated were first gastrointestinal bleed, first variceal bleed, all-cause deaths, bleed-related deaths and severe adverse events. The measure of association employed was relative risk; with heterogeneity and sensitivity analyses. RESULTS Variceal obliteration was obtained in 261 (91.6%) patients and target beta-blockers therapy was achieved in 294 (94.5%) patients (P = 0.19). Endoscopic variceal ligation compared with beta-blockers significantly reduced rates of first gastrointestinal bleed by 31% (RR, 0.69; 95% CI: 0.49-0.96; P = 0.03; NNTB = 15) and first variceal bleed by 43% (RR, 0.57; 95% CI: 0.38-0.85; P = 0.0067; NNTB = 11). All-cause deaths and bleed-related deaths were unaffected (RR, 1.03; 95% CI: 0.79-1.36; P = 0.81 and RR, 0.84; 95% CI: 0.44-1.61; P = 0.60 respectively). Severe adverse events were significantly less in endoscopic variceal ligation compared with beta-blockers (RR, 0.34; 95% CI: 0.17-0.69; P = 0.0024; NNTB = 28). Sensitivity analysis of five trials published in peer review journals and four trials with high quality showed results similar to those seen in the primary analysis of all the eight trials, confirming stability of conclusions. Following variceal obliteration with endoscopic variceal ligation, oesophageal varices recurred in 83 (29.1%) patients. Seven (28.1%) patients bled with one fatal outcome. In subgroup analyses, endoscopic variceal ligation had significant advantage compared wtih beta-blockers in trials including < or =30% patients with alcoholic cirrhosis, >30% patients with Child Class C cirrhosis and >50% patients with large varices. CONCLUSIONS In patients with cirrhosis with moderate to large varices and who have not bled, endoscopic varices ligation compared with beta-blockers significantly reduced bleeding episodes and severe adverse events, but had no effect on mortality.

Abstract
AIM Comparing the efficacy of peginterferon alpha-2b plus ribavirin with interferon alpha -2b plus ribavirin in Saudi patients with chronic hepatitis C virus (HCV) commonly infected with genotype 4. METHODS A total of 96 patients with chronic HCV infection were randomly assigned to two treatment groups. Forty-eight patients received once weekly 100 microg of peginterferon alpha-2b plus ribavirin given orally 800 mg/day (peginterferon group). Another 48 patients received thrice weekly 3 million units of interferon alpha-2b plus ribavirin 800 mg/day (interferon group). At the end of treatment (48 weeks) and sustained (72 weeks) biochemical and virologic responses were determined. RESULTS In the peginterferon group, 70.8% (34/48) patients attained both biochemical and virologic responses at the end of the treatment as against 52.1% (25/48) patients in the interferon group. (P=0.09 for both). Similarly, sustained biochemical and virologic responses in the peginterferon group were attained in 52.1% (25/48) and 43.8% (21/48) patients as against 43.8% (21/48) and 29.2% (14/48) patients in the interferon group, respectively (P=0.54 and 0.20, respectively). The sustained virologic response rates in patients with genotype 4 were 42.9% (12/28) in the peginterferon group and 32.3% (10/31) in the interferon group (P=0.43). Patients in peginterferon group had higher, although statistically not significant adverse reactions. CONCLUSIONS Saudi patients with chronic HCV attained a higher, although statistically not significant sustained virologic response with pegylated interferon plus ribavirin compared with interferon plus ribavirin.

Abstract
The early prognostic indicators for acute liver failure in endemic zones for hepatitis E virus have not been determined. All consecutive patients with acute liver failure from a geographically defined region endemic for hepatitis E virus were studied over the period April 1989-April 1996. Demographic, clinical and biochemical parameters were recorded at presentation and serum samples were analysed for known viral hepatitis (A-E) markers. Multiple parameters were compared in survivors and non-survivors in a univariate analysis. All significant factors on univariate analysis were entered into a stepwise logistic regression analysis to identify independent variables of prognosis. The sensitivity and specificity of significant prognostic factors was then assessed. A total of 180 [69 males and 111 females: age (mean +/- SD) 31.1 +/- 14.7 years] with acute liver failure were studied. Of these, 131 (72.8%) patients died. Hepatitis E virus was the aetiological cause in 79 (43.9%) patients, while hepatitis A virus, hepatitis B virus, hepatitis C virus and non-A, non-E agent/'s could be incriminated in four (2.1%), 25 (13.9%), 13 (7.2%) and 56 (31.1%) patients respectively. Of 83 women in childbearing age, 49 (59.0%) were pregnant, 33 (67.3%) of these were in the third trimester. Forty-seven (95.8%) pregnant women had HEV infection. Nine variables differed significantly between survivors and non-survivors on univariate analysis. Of these, four variables which predicted the adverse outcome on multivariate analysis were non-hepatitis-E aetiology, prothrombin time >30 s, grade of coma >2 and age >40 years in that order of significance. Pregnancy per se or duration of gestation did not adversely affect the prognosis. In endemic areas, hepatitis E virus is the commonest cause of acute liver failure. Acute liver failure occurs in a high proportion of pregnant women, mostly in third trimester. Early predictors of a poor outcome are non-E aetiology, prothrombin time >30 s, grade of coma >2 and age >40 years.

Abstract
Hepatitis E causes large-scale epidemics in endemic areas. The disease, during epidemics, has increased incidence and severity in pregnant women. Sporadic acute viral hepatitis (AVH) is common in endemic areas. The relationship of sporadic AVH and pregnancy has not been well studied. Over a 3-year period we prospectively studied 76 pregnant women and 337 non-pregnant women of childbearing age with sporadic acute viral hepatitis for aetiology, clinical course and outcome of disease. The aetiology in sporadic AVH was hepatitis A virus (HAV) in six (1.5%), hepatitis B virus (HBV) in 62 (15%), hepatitis C virus (HCV) in seven (1.7%), hepatitis D virus (HDV) co-infection in six (1.5%), hepatitis E virus (HEV) in 205 (49.6%), and hepatitis non-A-to-E (HNAE) in 127 (30.7%). Sixty-five (85.5%) pregnant women and 140 (41.5%) nonpregnant women had hepatitis E. The proportion of pregnant women was 31.7% in HEV group and 5.3% in non-HEV group [P < 0.001; OR=8.3 (95%C1 4.2-16.3)]. The prevalence of HEV in pregnant women in first trimester (76.9%), second trimester (88.9%), third trimester (83.8%) and puerperium (100%) did not differ significantly (P=0.09). Forty-seven (61.8%) of the 76 pregnant women developed fulminant hepatic failure (FHF), 69.2% in HEV group and 10% in non-HEV group (P < 0.001). Thirty-four (10.1%) nonpregnant women developed fulminant hepatic failure, 10% in HEV group and 9.7% in non-HEV group (P=0.86). FHF had occurred in four (40%) of 10 patients with HE in first trimester as against 41 (74.5%) of 55 patients in second trimester and beyond (P=0.015). Amongst the major complications of fulminant hepatic failure, cerebral oedema (53.2%) and disseminated intravascular coagulation (21.3%) occurred more often in pregnant women than in nonpregnant women (29.4% and 2.8%; P=0.03 and 0.016, respectively) while infections occurred more often in nonpregnant women (36.1%) than in pregnant women (10.6%; P=0.003). Fifty (61.7%) patients with FHF died [25 (53.2%) pregnant women and 25 (69.5%) nonpregnant women (P=0.06)]. Cerebral oedema and HEV aetiology were independent variables of survival in patients with FHF. Patients with cerebral oedema had worse prognosis and patients with HEV aetiology had best chances of survival. Hence HEV was the most common cause of sporadic AVH in this endemic area. High proportion of pregnant women and increased severity of disease in pregnancy were limited to patients with hepatitis E. Sporadic AVH caused by agents other than HEV did not show any special predilection to or increased severity in pregnancy. FHF in pregnant women caused by HEV was an explosive disease with short pre- encephalopathy period, rapid development of cerebral oedema and high occurrence of disseminated intravascular coagulation and may represent a severe manifestation of a Schwartzmann-like phenomenon.

Abstract
Ascariasis is a helminthic infection of global distribution with more than 1.4 billion persons infected throughout the world. The majority of infections occur in the developing countries of Asia and Latin America. Of 4 million people infected in the United States, a large percentage are immigrants from developing countries. Ascaris-related clinical disease is restricted to subjects with heavy worm load, and an estimated 1.2 to 2 million such cases, with 20,000 deaths, occur in endemic areas per year. More often, recurring moderate infections cause stunting of linear growth, cause reduced cognitive function, and contribute to existing malnutrition in children in endemic areas. HPA is a frequent cause of biliary and pancreatic disease in endemic areas. It occurs in adult women and can cause biliary colic, acute cholecystitis, acute cholangitis, acute pancreatitis, and hepatic abscess. RPC causing hepatic duct calculi is possibly an aftermath of recurrent biliary invasion in such areas. Ultrasonography can detect worms in the biliary tract and pancreas and is a useful noninvasive technique for diagnosis and follow-up of such patients. ERCP can help diagnose biliary and pancreatic ascariasis, including ascaris in the duodenum. Also, ERCP can be used to extract worms from the biliary and pancreatic ducts when indicated. Pyrantel pamoate, mebendazole, albendazole and levamisole are effective drugs and can be used for mass therapy to control ascariasis in endemic areas.

Abstract
We report a rare case of a patient with a primary hydatid cyst in the head of the pancreas who presented with obstructive jaundice caused by extrinsic compression of the intrapancreatic portion of the bile duct. The patient was treated successfully by ultrasound-guided percutaneous drainage of the cyst using hypertonic (20%) saline as the scolicidal agent and albendazole chemoprophylaxis before and after the drainage. The cyst was not visible on ultrasonography at 6 months follow up. Clinical, sonographic and serological follow up to 35 months showed no evidence of cyst recurrence or dissemination. In endemic areas of hydatid disease, hydatid cyst should be a differential diagnosis in cystic lesions of the pancreas in patients presenting with obstructive jaundice.

Abstract
BACKGROUND Haemosuccus pancreaticus is a rare complication of pancreatitis. It is a diagnostic problem for even the most astute clinician and a challenge for the expert endoscopist. We report a 25-year-old male patient who had all the features usually seen in haemosuccus pancreaticus patients: recurrent obscure upper gastrointestinal bleeding, pancreatitis, pseudocyst formation, ductal disruption, fistula and pancreatic ascites. The patient was treated by subtotal pancreatectomy, splenectomy and drainage of the pseudocyst. Although pancreatic duct communication with the surrounding vasculature could not be ascertained, we strongly believe the patient had haemosuccus pancreaticus because, over a follow-up period of 3 years, the patient was not only ascites free, but did not experience any further upper gastrointestinal bleeding. We believe that in evaluating patients with recurrent obscure gastrointestinal bleeding, one should always remember that the pancreas is a part of the gastrointestinal tract and, like other organs, is prone to blood loss.

Abstract
BACKGROUND In recent years percutaneous drainage has been used successfully to treat the hepatic hydatid cysts of echinococcal disease. We performed a controlled trial to compare the safety and efficacy of percutaneous drainage with those of surgical cystectomy, the traditional treatment. METHODS In a prospective study, we randomly assigned 50 patients with hepatic hydatidosis to treatment with percutaneous drainage (25 patients) or cystectomy (25). Albendazole (10 mg per kilogram of body weight per day for eight weeks) was administered to the patients who underwent percutaneous drainage. Serial assessments included clinical and biochemical examinations, ultrasonography, and serologic tests of echinococcal-antibody titers. RESULTS The mean (+/-SD) hospital stay was 4.2+/-1.5 days in the drainage group and 12.7+/-6.5 days in the surgery group (P<0.001). Over a mean follow-up period of 17 months, the mean cyst diameter decreased from 8.0+/-3.0 to 1.4+/-3.5 cm (P<0.001) after percutaneous drainage and from 9.1+/-3.0 to 0.9+/-1.8 cm (P<0.001) after surgery. The final cyst diameter did not differ significantly between the two groups (P=0.20). The cysts disappeared in 22 patients (88 percent) in the drainage group and in 18 (72 percent) in the surgery group (P=0.29). After an initial rise, the echinococcal-antibody titers fell progressively and at the last follow-up were negative (<1:160) in 19 patients (76 percent) in the drainage group and 17 (68 percent) in the surgery group (P=0.74). There were procedure-related complications in 8 patients (32 percent) in the drainage group and 21 (84 percent) in the surgery group, 17 of whom had fever postoperatively (P<0.001). CONCLUSIONS Percutaneous drainage, combined with albendazole therapy, is an effective and safe alternative to surgery for the treatment of uncomplicated hydatid cysts of the liver and requires a shorter hospital stay.

Abstract
PURPOSE To define the role of endoscopic dilatation/intubation and radiotherapy in squamous cell carcinoma of esophagus patients to improve their quality of life. METHODS AND MATERIALS One hundred and four patients with squamous cell carcinoma of the thoracic esophagus having Stage III and IV disease were enrolled in the present study, with 90 patients in Group 1 (nonesophagorespiratory fistula group) and 14 patients in Group 2 (esophagorespiratory fistula group). From Group 1 patients, 47 were subjected to radiotherapy (conventional) and had endoscopic dilatation and/or intubation whenever and wherever required (Group 1a), and 43 patients were allowed to follow the natural course of the disease except palliation with endoscopic dilatation and/or intubation whenever and wherever required (Group 1b). From Group 2, 4 patients received radiotherapy in addition to endoscopic intubation, while 10 patients received only endoscopic intubation. RESULTS The median survival for Group 1a was 7 months, for Group 1b--3 months, for Group 2a--4.25 months, and Group 2b--3.6 months. Only three patients from Group 1a survived more than 18 months, while no patient from Groups 1b, 2a, or 2b survived for more than 1 year. The difference in survival between Group 1a and 1b was statistically significant. CONCLUSION The addition of radiotherapy to endoscopic treatment definitely prolongs survival as well as improves the quality of life of these patients. We recommend both for the adequate palliation of patients with this disease.

Abstract
BACKGROUND The role of medical treatment for patients with bleeding peptic ulcers is uncertain. METHODS We conducted a double-blind, placebo-controlled trial in 220 patients with duodenal, gastric, or stomal ulcers and signs of recent bleeding, as confirmed by endoscopy. In 26 patients the ulcers showed arterial spurting, in 34 there was active oozing, in 35 there were nonbleeding, visible vessels, and in 125 there were adherent clots. The patients were randomly assigned to receive omeprazole (40 mg given orally every 12 hours for five days) or placebo. The outcome measures studied were further bleeding, surgery, and death. RESULTS Twelve of the 110 patients treated with omeprazole (10.9 percent) had continued bleeding or further bleeding, as compared with 40 of the 110 patients who received placebo (36.4 percent) (P<0.001). Eight patients in the omeprazole group and 26 in the placebo group required surgery to control their bleeding (P<0.001). Two patients in the omeprazole group and six in the placebo group died. Thirty-two patients in the omeprazole group (29.1 percent) and 78 in the placebo group (70.9 percent) received transfusions (P<0.001). A subgroup analysis showed that omeprazole was associated with significant reductions in recurrent bleeding and surgery in patients with nonbleeding, visible vessels or adherent clots, but not in those with arterial spurting or oozing. CONCLUSIONS In patients with bleeding peptic ulcers and signs of recent bleeding, treatment with omeprazole decreases the rate of further bleeding and the need for surgery.

More often, recurring moderate infections cause stunting of linear growth, cause reduced cognitive function, and contribute to existing malnutrition in children in endemic areas. Ascaris infection is acquired by the ingestion of the embryonated eggs. The larvae, while passing through the pulmonary migration phase for maturation, cause ascaris pneumonia. Intestinal ascaris is usually detected as an incidental finding. Ascaris-induced intestinal obstruction is a frequent complication in children with heavy worm loads. It can be complicated by intussusception, perforation, and gangrene of the bowel. Acute appendicitis and appendicular perforation can occur as a result of worms entering the appendix. HPA is a frequent cause of biliary and pancreatic disease in endemic areas. It occurs in adult women and can cause biliary colic, acute cholecystitis, acute cholangitis, acute pancreatitis, and hepatic abscess. RPC causing hepatic duct calculi is possibly an aftermath of recurrent biliary invasion in such areas. Ultrasonography can detect worms in the biliary tract and pancreas and is a useful noninvasive technique for diagnosis and follow-up of such patients.

Abstract
Little is known about vertical transmission of hepatitis E virus from infected mothers to their infants. We studied eight babies born to mothers infected with hepatitis E in third trimester. One baby was icteric at birth with elevated transaminases and four babies had anicteric hepatitis. Two babies were born with hypothermia and hypoglycaemia and died within 24 h; one had massive hepatic necrosis. Hepatitis E virus RNA was detected by PCR in cord or birth blood samples of five infants. Six infants had evidence of hepatitis E infection. We conclude that hepatitis E virus is commonly transmitted from infected mothers to their babies with significant perinatal morbidity and mortality.

Abstract
A solid phase enzyme linked immunosorbent assay (ELISA) that detects IgM and IgG to hepatitis E virus (HEV) was used to study seroepidemiology in 40 healthy subjects and 227 consecutive patients with liver diseases in an endemic area. Fifty-two of the liver diseases patients (22.9 percent) had acute hepatitis E. In contrast, none of the 40 healthy subjects were positive for IgM anti-HEV, validating the ELISA assay. Twenty-three of 25 (92%) patients with epidemic non-A, non-B hepatitis were confirmed as having acute hepatitis E. Only 1 of the 10 patients with sporadic, fulminant hepatic failure of non-A, non-B, non-C etiology was positive for IgM anti-HEV. Five (31.2%) of the 16 patients with acute hepatitis in HBsAg carriers were positive for IgM anti-HEV. One patient with acute hepatitis B was coinfected with acute hepatitis E. Acute hepatitis was a disease of the adult population, with peak attack rates in the second and third decades of life. This disease was seen in only 4 (16%) of the 25 patients with acute viral hepatitis occurring below 14 years of age. Cholestasis was predominant in 25% of patients, enzyme elevation was monophasic, and all patients had clinical and biochemical recovery from the disease. The data suggest that the majority of patients with acute sporadic non-A, non-B, non-C hepatitis in India have hepatitis E. However, fulminant hepatic failure to sporadic nature is rarely from hepatitis E.

Abstract
From December 1989 to March 1992, 50 (32%) of 156 patients with hepatobiliary and pancreatic ascariasis underwent various endoscopic interventional procedures. Endoscopic intervention was performed when patients did not respond to energetic symptomatic treatment within the first few days of hospitalization (n = 45) or when worms had not moved out of the ducts into the duodenum at 3 weeks (n = 5). Worm extraction was successful in all 18 patients from the ampullary orifice and in 34 (89.5%) of 38 patients from the bile or pancreatic duct. In five patients with pyogenic cholangitis, endoscopic nasobiliary drainage was performed to decompress the bile ducts. After worm extraction/nasobiliary drainage, 41 (91%) of the 45 patients with biliary disease (n = 42) or acute pancreatitis (n = 3) had rapid relief of symptoms. Three patients developed complications related to endoscopy, including cholangitis (n = 2) and hypotension (n = 1).

Abstract
From December 1982 to December 1991, cholangiograms were obtained in 227 patients with recurrent pyogenic cholangitis. Cholangiographic abnormalities included biliary dilation, calculi, sludge, excessive branching, and arrowhead formation of intrahepatic ducts and biliary strictures. In 21 patients, previous evidence of biliary ascariasis was seen. Repeat cholangiograms were performed in 55 patients in a follow-up period of 18.0 +/- 1 months. Of these patients, 12 treated conservatively continued to get recurrent cholangitis and revealed worsening abnormalities on repeat cholangiograms. Another 25 patients had successful endoscopic sphincterotomy and extraction of biliary calculi. These patients remained free of symptoms on follow-up, with significant resolution of abnormalities on repeat cholangiograms. The remaining 18 patients with failed surgical or endoscopic interventions continued to get recurrent episodes of cholangitis and worsening of abnormalities on repeat cholangiograms. This retrospective study indicates that the natural course of recurrent pyogenic cholangitis is a progressive, destructive cholangiopathy. Ascaris lumbricoides invasion of the biliary tree is an initiating event in a sub-group of patients.

We prospectively studied 21 consecutive patients with extrahepatic portal venous obstruction for evidence of biliary tract disease. Two patients were first seen with extrahepatic cholestasis; another had recurrent cholangitis. All three patients with clinically manifest biliary disease were adults. Another five patients had icterus on clinical examination. Liver function tests revealed elevated bilirubin levels in 14 patients (66.6%), elevated alkaline phosphatase levels in 17 (80.9%) and elevated serum ALT levels in 8 (38.0%). Endoscopic retrograde cholangiography revealed abnormal findings in 17 patients (80.9%). The changes involved the common bile duct (66.6%) more often than they did the hepatic bile ducts (38.1%). Cholangiographic abnormalities included strictures (52.4%), caliber irregularity (23.8%), segmental upstream dilatation (42.8%), ectasia (9.5%), collateral veins causing extraluminal bile duct impressions (14.3%), displacement of ducts (9.5%), angulation of ducts (4.7%) and pruning of intrahepatic ducts (9.5%). The pathogenesis of such cholangiographic abnormalities is unknown. However, possible factors in such changes include collateral veins bridging the blocked portal vein, causing bile duct impressions; fibrous scarring of porta hepatis, causing angulation of bile duct; and ischemic injury to bile duct, leading to stricture formation and caliber irregularity. Biliary disease is important in the clinical outcome of patients with extrahepatic portal venous obstruction because variceal sclerotherapy has prolonged the life expectancies of such patients.

Abstract
BACKGROUND Recently, drug treatment and percutaneous drainage have been used successfully when treating hepatic hydatid cysts. Until now, there is no published study comparing the relative safety and efficacy of these two forms of treatment. METHODS In a prospective study, 33 hepatic hydatid cysts were randomly distributed to receive percutaneous drainage (10), albendazole (10 mg.kg-1.day-1 for 8 weeks) plus percutaneous drainage (12), and albendazole alone (11). Patients were serially assessed by clinical and biochemical examinations, ultrasonography, and hydatid serology. RESULTS On serial ultrasonography, cysts attained heterogeneous echopattern in 18, uniform echogenicity in 11, and disappearance in 3. All 22 cysts treated with percutaneous drainage and only 2 (18.2%) cysts treated with albendazole alone reduced in size and change in echopattern (P < 0.01). Maximum size reduction was observed in cysts treated with a combination of percutaneous drainage and albendazole (P < 0.05). Complications observed with drainage were cyst infection in 2 patients, fever in 3, cyst biliary rupture in 1, and urticaria in 2. These were managed successfully without any mortality. Three patients who received albendazole developed reversible elevation of liver cell enzymes. CONCLUSIONS It was concluded that percutaneous drainage with albendazole therapy is an effective form of management for hepatic hydatid cysts.

Abstract
The prevalence of serum antibodies to hepatitis C virus was assessed by an enzyme-linked immunosorbent assay in patients with epidemic non-A, non-B hepatitis (14), sporadic non-A, non-B hepatitis (42), chronic hepatitis (14) and cirrhosis (26). None of the patients with epidemic non-A, non-B hepatitis (14) and acute self-limiting sporadic non-A, non-B hepatitis without prior parenteral exposure (38) tested positive for hepatitis C virus antibody. Based on epidemiologic features, hepatitis E virus is presumably the etiologic agent for both these entities. Hepatitis C virus (HCV) antibody was positive in none of the patients with cryptogenic chronic hepatitis (11) and in 2(8%) patients with cryptogenic cirrhosis (25). It was concluded that cryptogenic chronic hepatitis and cirrhosis in India may be caused by alternative viral agents of the non-A, non-B type or by hepatotoxins to which the population may be exposed. Of 8 patients with prior parenteral exposure (transfusions 6, needle pricks 2) 5 (62.5%) patients tested positive for HCV antibody. HCV antibody was detected in 1 (25%) patient with acute self-limiting, parenterally transmitted non-A, non-B hepatitis and in 4 (100%) patients with chronic parenterally transmitted non-A, non-B hepatitis.

Abstract
Sonographic and cholangiographic appearances of confirmed intrabiliary rupture of a hepatic hydatid cyst were studied in 15 cases. Sonographic findings included liver cyst in all cases; nonshadowing echogenic structures in the dilated biliary tree representing hydatid material, such as fragmented membranes, sand, matrix, and daughter vesicles, in eight cases; and loss of continuity of the cyst wall adjacent to the bile duct representing the site of communication in seven cases. Cholangiographic findings were as follows: filling defects of varying size and shapes in the dilated biliary tree in 13 cases, and changing shape and position of these filling defects in three of them; and leakage of contrast medium into the cyst cavity in 12 cases. Intrabiliary rupture of hepatic hydatid cyst was suggested by sonography in 10 cases (66.7%) and at cholangiography in 13 cases (86.6%). We conclude that a joint application of sonography and endoscopic cholangiography is mandatory for proper preoperative evaluation of this disorder.

Abstract
The incidence, clinical disease and outcome of acute pancreatitis caused by ascariasis in an endemic area of Kashmir, India, was studied prospectively. Ascariasis was an aetiological factor in 59 of 256 patients (23.0 per cent) with acute pancreatitis. Worms had invaded the bile duct in 51 patients, the pancreatic duct in four and both ducts in four. Pancreatitis was mild in 46 patients and severe in 13. Associated pyogenic cholangitis was present in eight. Acute complications occurred in 11 patients. Endoscopic retrograde cholangiopancreatography (ERCP) was performed in all cases within 72 h of admission and delineated ascarides in the duodenum invading the ampullary orifice (44 patients), in the bile duct (55) and in the pancreatic duct (eight). At ERCP, worms were extracted from the ampullary orifice and removed via the mouth of 33 patients with intractable epigastric pain, leading to rapid relief of symptoms. The eight patients with pyogenic cholangitis underwent endoscopic nasobiliary drainage to decompress the bile ducts; worms were extracted from the bile duct of three of these patients using a Dormia basket. A total of 56 patients recovered from acute illness with a combination of conservative and endoscopic treatment; the other three required emergency surgery. At a mean(s.d.) follow-up of 19(7) months, ten patients showed symptomatic worm reinvasion of the biliary tree. The overall mortality rate was 3 per cent.

Abstract
Invasion of the adult roundworm, Ascaris lumbricoides, into the gallbladder is rare and was seen in 14(2.1%) of the 665 cases with hepatobiliary ascariasis. The diagnosis was suggested in all 13 cases in which sonography was performed and in 5 of the 11 cases at endoscopic retrograde cholangiography. Sonographic findings included a nonshadowing, long, echogenic structure in the form of a coil, an echogenic strip with central anechoic tube, an echogenic structure extending across the gallbladder giving it a septate appearance, and characteristic erratic, nondirectional, zig-zag movements of these echogenic structures in the gallbladder. Serial sonograms accurately predicted spontaneous exit of the worm. Pregnancy and anomalous origin of the cystic duct directly from the papilla of Vater facilitated worm invasion into the gallbladder. We conclude that real-time sonography offers a simple, rapid approach for the diagnosis and follow-up of patients, whereas endoscopic retrograde cholangiography has limited diagnostic value in this disorder.

Abstract
We studied epidemics of viral hepatitis occurring at three different places in India. One was a combined epidemic due to hepatitis E virus (HEV) and hepatitis A virus (HAV) infections. In this epidemic, HAV affected children below 10 years of age, whereas HEV infected the young adult population. HEV was transmitted to rhesus monkeys (Macaca mulata) and confirmed by the polymerase chain reaction (PCR) on bile from the animals. Fecal material from acutely infected patients in one of the epidemics was also found positive for HEV RNA by PCR. This may help in confirming the nature of future epidemics. The bile and liver from experimental animals can be used as a source of material for further virological and molecular biological studies of HEV.

Abstract
This study was undertaken to assess the role of person-to-person transmission in hepatitis E and the ability of immune serum globulin (ISG) from an Indian source to prevent such transmission. Seventy six subjects (62 household contacts of patients with sporadic hepatitis E and 14 controls with no household contacts) were studied clinically, biochemically and serologically at entry and fortnightly thereafter for the next 8 weeks. Thirty two household contacts received 2 mL of 16.5% ISG 16.5% while the other 30 household contacts and 14 controls received 2 mL of normal saline intramuscularly at entry. Eighteen (29%) household contacts and none of the control subjects developed biochemical evidence of acute hepatitis E (p less than 0.01). The enzyme elevation occurred after a mean interval of 31.0 +/- 4.5 days from the onset of disease in the index case. This suggested that the disease in the case contacts had been contracted by household contact with the index case and not by simultaneous infection of the index case and the household contact. The incidence of disease was similar in the household contacts receiving ISG and normal saline (25% and 33.3% respectively, p = ns). ISG had no effect on the time interval to SGPT rise or on the severity of disease in household contacts.

Abstract
1. Twenty-eight patients who fulfilled entry criteria for sphincter of Oddi dysfunction were randomly allocated to receive nifedipine and placebo in a cross over design with 12 week treatment periods separated by a 2 week wash-out. 2. All patients had episodic pain resembling biliary pain, had previously undergone cholecystectomy, had elevated alkaline phosphatase during episodes of pain and had elevated basal pressure on sphincter of Oddi manometry. 3. Compared with placebo, significant decreases in cumulative pain score, number of pain episodes, oral analgesic tablets consumed and emergency room visits were observed during nifedipine treatment. 4. Overall 21 patients improved during nifedipine therapy while seven patients did not. None of the following predicted response to nifedipine therapy: enzyme levels, morphine-Prostigmine test, fatty meal sonography, common duct diameter and pressure, sphincter of Oddi phasic pressure, frequency and duration of phasic waves and maximal fall in the basal pressure at sphincter of Oddi manometry after sublingual administration of nifedipine. However patients with predominant antegrade propagation of phasic contractions of sphincter of Oddi did significantly better on nifedipine than those with abnormal propagation of phasic contractions. 5. Nifedipine therapy orally in maximal tolerated doses relieves pain in patients with sphincter of Oddi dysfunction who have elevated basal pressure and sphincter of Oddi phasic contractions of predominantly antegrade nature.

Abstract
Over a three year period (1 July 1986 to 30 June 1989) all newly diagnosed and histologically proved cases of oesophageal and gastric cancer were recorded prospectively. Some 1515 cases of oesophageal cancer (1050 men and 465 women) and 966 cases of gastric cancer (789 men and 177 women) were registered. Seven patients had simultaneous oesophageal and gastric cancer. Age standardised incidence rates for oesophageal cancer were: men 43.6/100,000 per year; women 27.9/100,000 per year. The rates for gastric cancer were: men 36.7/100,000 per year, women 9.9/100,000 per annum. These figures were three to six times higher than those recorded by cancer registries in Banglore, Madras, and Bombay. The incidence rates for oesophageal and gastric cancer in Islamabad (southern district of Kashmir) were 4.1 to 5.4 times higher in men and 1.5 to 2.0 times higher in women than those for Kupwara (northern district of Kashmir). The incidence rates for oesophageal and gastric cancer in Muslims, Hindus, and Sikhs were different. The epidemiology of oesophageal cancer in Kashmir was similar to that found in the 'Asian oesophageal cancer belt'. At the same time Kashmir also had an unprecedented high incidence of gastric cancer. Kashmiries have special personal and dietary habits. Further studies are needed to define the relation between these habits and the occurrence of oesophageal and gastric cancer.

Abstract
The hypothesis that the cytodiagnostic results on endoscopic brushings obtained before biopsy may be superior to those brushings obtained after biopsy, but with the accuracy of the subsequent biopsy reduced, was examined for 300 consecutive patients, including 256 with esophageal or gastric carcinomas. Following stratification by site and endoscopic appearance of their lesions, the patients were randomized to undergo brushing either before or after forceps biopsy. The accuracy of brushing cytology in patients with carcinoma was significantly higher when the brushing was performed before biopsy than after biopsy (93.5% versus 82.6%; P less than .01). The diagnostic yield of the biopsy was not significantly different whether the lesions were brushed before or after the biopsy (92.7% versus 93.2%; P less than .5). The diagnostic superiority of brushings obtained before biopsy did not relate to the site or endoscopic appearance of the tumor. There were no false-positive cytologic or histologic reports. For all 256 carcinomas, the cumulative accuracy (brushing cytology plus biopsy) reached 98.8% and was significantly better (P less than .001) than that of biopsy alone (93.9%) or cytology alone (87.9%). Apart from reinforcing the belief that the combined application of brushing and biopsy is mandatory for achieving optimal results, this study indicated that the brushing should be performed before the biopsy.

Abstract
Antihelmintic treatment with piperazine (1,4-diazacyclohexane) for microfilarie parasitism results in the endogenous formation of piperazine-derived N-nitrosamines. The urinary excretion of these N-nitrosamines was determined by biochemical monitoring of 14 patients receiving 2 g piperazine citrate. The urinary excretion (mean +/- SD) of N-mononitrosopiperazine (MNPz) was 27.0 +/- 26.7 micrograms/day (range 0.6-96.0 micrograms/day). Trace levels of 0.73 +/- 0.92 micrograms/day N,N'-dinitrosopiperazine (DNPz) (range ND-2.8 micrograms/day) were also found in 7 of 14 urine samples. N-Nitroso-3-hydroxypyrrolidine (NHPYR), a metabolite of both MNPz and DNPz, was detected in 11 of 14 urine samples at a mean concentration of 1.74 +/- 1.72 micrograms/day (range ND-5.7 micrograms/day) and traces of N-nitrosodiethanolamine in two samples at levels of 0.3 and less than 0.1 micrograms/day. The results show that biochemical monitoring of urinary NHPYR may be a good indicator of endogenous MNPz formation. While DNPz was also detected in urine, conclusive validation for its endogenous formation could not be provided because no evidence was found for the presence of its major metabolite, N-nitroso-(2-hydroxyethyl)glycine in urine.

Abstract
Twenty-one hepatic Echinococcus granulosus cysts (maximal diameter, 7.5 cm +/- 4.0) in 12 patients were aspirated and irrigated with hypertonic (20%) saline under sonographic guidance. All patients had signs and symptoms of a hepatic mass caused by the cysts, which had a prominent fluid component that appeared anechoic or hypoechoic, with marked enhancement of back wall echoes. The amounts of cyst fluid aspirated and of hypertonic saline used were 190 mL +/- 240 and 120 mL +/- 90, respectively. Separation of the endocyst from the pericyst and nonviability of scoleces were observed in all cysts. Mean hospital stay was 4.0 days +/- 3.4. Serial sonographic examinations revealed high-level echoes in the cyst cavity (heterogeneous echo pattern), which ultimately became uniformly echogenic (pseudotumor). After follow-up of 14.0 months +/- 5.5, maximal cyst diameter decreased to 4.1 cm +/- 3.1 (P less than .001). One patient died of unrelated causes; the remaining 11 patients experienced relief of symptoms and a decrease in liver span.

Abstract
In a prospective study we compared the diagnostic accuracy of endoscopic fine needle aspiration cytology with that of brush cytology and forceps biopsy in relation to gross tumour pattern and site in 265 confirmed consecutive cases of malignancy of the oesophagus, stomach, colon, and rectum. Aspiration cytology gave the highest diagnostic accuracy (94%), which was significantly better than that of brush cytology (84.9%) and biopsy (87.2%) (p less than 0.005). The difference was mainly related to tumour pattern. When compared to brush cytology and biopsy aspiration cytology was significantly better in submucosal tumours (92.9% v 7.1% and 14.3%, p less than 0.001); in infiltrative malignancies (95.8% v 90.1% and 78.9%, p less than 0.01), and in ulceronecrotic malignancies (90.9% v 36.4% and 45.4%, p less than 0.05). In polypoid malignancies there was a significant trend (p less than 0.05) in favour of forceps biopsy, with a diagnostic yield of 100% compared with 95% for aspiration cytology and 93.3% for brush cytology. The accuracy of the different techniques was not significantly related to the site of the tumour. The cumulative accuracy of aspiration cytology and biopsy was significantly better than that of biopsy and brush cytology (98.5% v 90.9%, p less than 0.005). Aspiration cytology was diagnostic in 21 of 24 lesions that were negative with both brush cytology and biopsy. There were no false positive cytology or histology results. We conclude that aspiration cytology is a simple, safe, and reliable technique with a high diagnostic yield and is of particular value in submucosal, infiltrative, and ulceronecrotic tumours.

Abstract
The conservative treatment of solitary rectal ulcer is generally unsatisfactory. Six patients, aged 27-54 years, with recurrent solitary rectal ulcer were treated with topical administration of sucralfate in a daily dose of 2 g twice a day for 6 weeks. Four patients experienced complete relief of symptoms and the remaining two patients had marked improvement. Although macroscopic healing of the ulcer was apparent in all, histologic improvement was not appreciable. Five of the six patients remain in remission during a follow-up period of 4-14 months (mean, 8 +/- 1.5 months). Recurrence was observed in one patient at 5 months, which satisfactorily resolved with sucralfate enemas. From these preliminary observations we infer that solitary rectal ulcer can be effectively treated with topical application of sucralfate.

Abstract
Ultrasonically (US) guided fine-needle aspiration biopsy was performed in 88 patients who had gallbladder masses. All masses were less than 4.8 cm in diameter. A 22- or 23-gauge, Teflon-coated needle was placed into the mass with the transhepatic or transperitoneal route. By means of this technique, gallbladder malignancy was confirmed in 69 of the 78 cases of malignancy (88.5%). Ten of 10 benign lesions were properly categorized. One patient developed bile peritonitis following a single needle pass with the transperitoneal approach. Pain, a minor complication of the procedure, was noted in four cases. No instances of hemorrhage or vasovagal reactions occurred. From their experience in this large series, the authors conclude that US-guided fine-needle aspiration biopsy of gallbladder masses is a safe, reliable, and accurate technique for the diagnosis of malignancy.

Abstract
500 patients with hepatobiliary and pancreatic disease due to Ascaris lumbricoides infection were studied. 274 patients had duodenal ascariasis, 171 biliary ascariasis, 40 hepatic ascariasis, 8 gall bladder ascariasis, and 7 pancreatic ascariasis. Five clinical presentations were recognised: acute cholecystitis (64 patients), acute cholangitis (121), biliary colic (280), acute pancreatitis (31), and hepatic abscess (4). Ascarides in the duodenum (which were seen to invade only the ampullary orifice) induced either severe biliary colic or episodes of acute pancreatitis. 27 patients had pyogenic cholangitis and were managed by surgical (2) or endoscopic (25) biliary decompression and drainage. Removal of worms from the ampullary orifice and their extraction by mouth led to rapid relief of biliary colic (214 patients) and acute pancreatitis (16). 4 patients died (acute pancreatitis 2, pyogenic cholangitis 1, hepatic abscess 1). In 12 patients worms persisted in the biliary tree at 3 weeks; dead worms were removed from the biliary tree by surgery (5 patients) or with an endoscopic basket (7). Worms moved out of the ductal system in 211 patients. During a mean follow-up of 48 months (SD 14), 76 patients had worm re-invasion of the biliary tree due to ascaris re-infection. Intrahepatic duct and bile duct calculi developed in 7 patients in whom dead worms formed the nidus of stones.
