Abstract
BACKGROUND The natural history of fulminant hepatic failure (FHF) without liver transplantation is not well known. AIMS To study the natural history and prognostic factors, especially the presence of ascites and spontaneous bacterial peritonitis (SBP), in children with FHF. METHODS FHF was defined by the onset of encephalopathy within 12 weeks of onset of jaundice. From August 1997 to December 2000, 67 children (< or =12 years) were diagnosed with FHF. Their clinical features, investigations and outcome were noted. Viral markers A to E (IgM, anti-HAV; IgM, anti-HEV, HBsAg, and anti-HCV) were determined by ELISA. SBP was defined by the presence of > or =250 neutrophils with or without a positive culture in ascitic fluid. RESULTS Mean age of the children was 5.8 years with an almost equal sex distribution. Viral markers were positive in 63 (94%) cases: hepatitis A in 34 (54%), E in 17 (27%), A+E in seven (11%), and B in five (8%). Thirty one children presented with grade I or II encephalopathy and all recovered, whereas 17 of 36 children who had grade III or IV encephalopathy died. Ascites was detected (both clinically and ultrasonically) in 34 (51%) cases, nine (26%) of which had SBP. Overall mortality was 25%. Mortality was higher in those who had ascites than in those who did not (32% v 18%); among those with ascites it was maximum in those who had SBP (78% v 16%). Total serum bilirubin and grade of encephalopathy were significantly higher, serum albumin was significantly lower, and prothrombin time was significantly prolonged in those who died than in those who recovered. CONCLUSION The natural history of FHF in Indian children depends on age, grade of encephalopathy, ascites, and SBP. SBP depicts worse outcome. In all cases of FHF with ascites, the presence of SBP should be investigated.

Abstract
Nutrition has very important role to play during health and disease state in human beings. Neonates and younger children are more prone to develop nutritional deficiencies. They have very critical reserves and are rapidly growing. Any surgical insult leads to multiple nutritional problems. Careful planning of nutritional management in a surgical patient is mandatory. Nutritional support should start from the day when the child develops the surgical condition to withstand stress of disease and surgical procedure. In the postoperative period nutritional support should start as early as possible. Start with small amount and build up gradually till the normal enteral nutrition (EN) is tolerated. When EN is not tolerated parenteral nutrition (PN) should be considered. Parenteral nutrition on short term basis is very important to tide over the crisis due to postoperative complications. Parenteral nutrition on long term basis is required in short bowel syndrome resulting from resection of large part of the gut. During PN, enteral nutrition should be continued in small amounts in order to maintain the integrity of mucosal lining of the gut. Enteral nutrition is more physiological and can provide adequate amount of immunonutrients, minerals and vitamins.

Abstract
BACKGROUND Little information is available regarding the safety and efficacy of dilation of esophageal strictures in children with Savary-Gilliard bougies. This is a report of our experience with this form of dilation in Indian children. METHODS One hundred seven Indian children age 14 years or younger with benign esophageal strictures underwent dilation. Clinical information including etiology was recorded. Dilation was performed at 2- to 3-week intervals by using Savary-Gilliard bougies under ketamine sedation and was considered adequate if the esophageal lumen could be dilated to 15 mm diameter (12.8 mm in children <5 years of age) with complete relief of symptoms. Subsequently, dilation was performed on an "as needed" basis. RESULTS Mean age was 4.8 +/- 3.4 years; male to female ratio was 3:1. Fifty-four children had corrosive strictures (acid 34, alkali 20). Noncorrosive strictures were sclerotherapy-induced (23), postsurgical (14), congenital (10), peptic (4), and due to other causes (2). Dilation was successful in all but 3 cases. Corrosive strictures required a significantly higher number of sessions to achieve adequate initial dilation (2.4 +/- 1.9 vs. 1.3 +/- 0.5, p < 0.01). Patients with corrosive strictures also required a higher number of subsequent sessions for recurrence (7.3 +/- 6.5 vs. 0.7 +/- 1.3, p = 0.10). Dilation was also successful in patients with strictures 5 cm or more in length and/or patients with multiple corrosive strictures, although these required a higher number of sessions to achieve adequate dilation (p < 0.05) and also higher number of subsequent sessions for recurrence. Six esophageal perforations occurred during 648 dilation sessions (0.9%); 5 occurred in patients with corrosive strictures. One patient required surgery. CONCLUSIONS Corrosive injury is the most common cause of benign esophageal strictures in Indian children. Savary-Gilliard bougie dilation is safe and effective, even for long and/or multiple corrosive strictures.

Abstract
BACKGROUND AND AIM The role of endoscopic retrograde cholangiopancreatography (ERCP) is not yet fully established in children. The purpose of this study was to assess the use of ERCP in the diagnosis and management of various pancreaticobiliary disorders in children. METHODS Eighty-four ERCPs were performed over 5.5 years in 72 children with suspected pancreaticobiliary tract disorders with an adult-type duodenoscope. In all cases, indications, procedure time, ERCP findings, complications, patients course and therapeutic intervention (if any) were recorded. RESULTS The mean (+/- SD) age of these children was 8.8 +/- 3.3 years. Successful cannulation was possible in 70 (97%) cases. Of the 44 cases with suspected biliary tract disease, 14 had a choledochal cyst, 13 had portal biliopathy, two each had CBD stones, primary sclerosing cholangitis and a bile leak, one had biliary ascariasis, eight had a normal cholangiogram, and CBD cannulation failed in two. Eight of the 28 children with suspected pancreatic disorders had chronic pancreatitis, five had pancreatic duct disruption, three had pancreas divisum and the rest had a normal pancreatogram (including all eight children with unexplained abdominal pain). Therapeutic ERCP was performed in 22 children, endoscopic nasobiliary or a nasocystic drain was placed in 16, biliary stenting was conducted in two, pancreatic duct stenting was conducted in three, and minor papilla dilation was conducted in one child. Six children had mild procedure-related complications. CONCLUSION Endoscopic retrograde cholangiopancreatography is very useful in the treatment of cholangitis, bile leak, pseudocyst and pancreatic fistulae in children. However, its role in unexplained abdominal pain is doubtful.

Abstract
Rapid methods for detection of Escherichia coli O157: H7 diarrhoea are preferred to limit differential diagnostic evaluation including invasive procedures. Fifty stool samples from children and adult patients having diarrhoea and ten control samples from volunteers without diarrhoea were collected. Each sample was inoculated into two tubes containing peptone water and one containing MacConkey broth. They were incubated for 5 hours or longer till growth occurred. The first tube of peptone water with growth was tested for production of indole. All samples were tested for enzyme beta-glucuronidase in the pellet of the second peptone water growth. The MacConkey broth growth was tested with latex beads sensitized separately with antisera to E. coli O157 and E. coli H7. All indole positive and beta glucuronidase negative samples with positive agglutination with E. coli O157 and H7 coated latex beads were taken as E. coli O157: H7 positive samples. Three out of 50 diarrhoeic samples were found to be positive for E. coli O157:H7. Confirmation of the results of our rapid assay was done by parallel conventional culture of faecal specimens on sorbitol MacConkey agar. Our rapid assay required only 7-10 hours compared to the conventional technique where the report is available only on the third day. It can therefore be used routinely for initial screening of faecal specimens for E. coli O157: H7.

Abstract
BACKGROUND AND OBJECTIVES Non-cirrhotic portal fibrosis (NCPF) is an infrequent cause of portal hypertension in children. We report 11 children with NCPF, from among 338 with portal hypertension, seen over 6.5 years. METHODS The diagnosis was based on patent splenoportal axis on ultrasonography and/or splenoportal venography and liver biopsy showing no evidence of cirrhosis or other diagnosis, in children with portal hypertension. Those with variceal bleed were managed with endoscopic sclerotherapy and/or shunt surgery. RESULTS The median age was 11 years (range 5 to 14), and 8 were boys. Presentation was with variceal bleed in 6, lump in left upper abdomen in 5 (though all children had splenomegaly) and esophageal varices on endoscopy. The median spleen enlargement was 8.5 cm; 8 also had hepatomegaly. Hypersplenism was present in 7, and two had developed ascites after bleed. Of 6 children presenting with bleed, variceal obliteration was achieved on sclerotherapy (average 5.6 sessions) in 4 while two underwent shunt surgery for associated hypersplenism. After median follow up of 57.5 months (range 12-78) all are alive and well. CONCLUSION NCPF is an uncommon cause of portal hypertension in Indian children. Presentation with variceal bleed is less common than in adults; sclerotherapy is effective.

Abstract
Enteropathogenic Escherichia coli (EPEC) are known to cause infantile enteritis. We studied the prevalence of EPEC in paediatric patients with acute and persistent diarrhoea. A total of 56 stool samples from paediatric patients were studied. There were 28 significant bacterial isolates. Of these 21 were untypable E. coli, 5 were typable E. coli, four of which belonged to members considered to be enteropathogenic. Non E. coli isolates grown in pure culture were one each of Pseudomonas aeruginosa and Citrobacter freundi. The study reveals the definitive role of EPEC in childhood diarrhoea at all age groups and emphasizes the need for characterisation of all significant E. coli isolates in this age group.

Abstract
BACKGROUND Congenital hepatic fibrosis (CHF) is an uncommon cause of portal hypertension in children. So far, there is no report of this from the subcontinent. We have studied the clinical spectrum of CHF in North Indian children. METHODS Fifteen children were diagnosed with CHF on the basis of their liver histology over a period of 6.5 years. Their clinical details were recorded. Oesophagogastroduodenoscopy and abdominal ultrasonography were performed in all cases. All siblings were examined clinically; and ultrasonography, endoscopy and liver biopsy were performed if there was firm hepatomegaly. Children with variceal bleeding were managed by endoscopic sclerotherapy. The median age of these children was 8 years with a male to female ratio of 1.5:1. RESULTS Only one sibling (of 33) was diagnosed as having CHF. The predominant presentations were variceal bleeding in six, abdominal distension in seven and incidental detection of organomegaly in two. Hepatomegaly was present in all patients and splenomegaly in all but one. Liver function and renal function tests were normal in all children, except for a raised serum alkaline phosphatase in six. Two children had associated renal cysts, two had choledochal cysts, one each had Caroli's disease and biliary atresia and two children had portal vein thrombosis. Variceal obliteration was achieved in five children after an average 4.8 sclerotherapy sessions and one required a mesocaval shunt. On follow up (median 41 months, range 1-80 months) all are doing well. CONCLUSIONS Congenital hepatic fibrosis is mainly sporadic in India and associated renal lesions are uncommon. Endoscopic sclerotherapy is effective in controlling variceal bleed and the prognosis is universally good in the absence of renal diseases.

Abstract
Childhood liver disorders have, in general, mode of presentations which are distinct from that in adult population. It is due to varying etiology and natural history of the liver diseases in childhood. Chronic hepatitis B and C can be managed with alpha interferon. Remission rates in children have been reported to be between 20-58%. Recently available lamuvidine has also been used in combination with interferon therapy. Oral chelation therapy and liver transplantation have radically affected the outcome of patients with Wilson's disease. Corticosteroids and immunosuppressive therapy are effective in reducing both morbidity and mortality due to auto-immune hepatitis. Offending carbohydrates are eliminated from the diet of patients with galactosemia and hereditary fructose intolerance. The most important and often neglected component of management of chronic liver diseases in childhood are nutritional management and prompt interventions for ascites, spontaneous bacterial peritonitis, portal hypertension and hepatic encephalopathy. With definitive etiological and histological assessment and institution of specific as well as supportive therapy, children with chronic liver disease can have a prolonged survival with improved quality of life. Several of them can potentially receive the liver transplant as and when it becomes available.

Abstract
An indigenously developed latex agglutination assay using C. sordelli antitoxin was used to screen 211 stool samples received from hospitalized patients. Of 126 samples from patients receiving single to multiple antibiotics for various ailments, 38 (30%) were positive by the toxin assay, whereas only 6/85 (7%) of samples of patients not receiving antibiotics were also positive. Thus, of 211 samples a total of 44 (20.8%) were positive by our toxin assay, giving titers ranging from 1 in 5 to 1 in 320. The test developed by us is simple, rapid, easy and reliable and can be easily adapted to all microbiology laboratories.

Abstract
Celiac disease is well documented especially from northern parts of India. It should be suspected in a child having chronic diarrhoea with growth failure. There are unusual manifestations like refractory anemia, rickets, recurrent abdominal pain and short stature without other gastrointestinal manifestations. Definitive diagnosis still requires undertaking multiple intestinal biopsies, before and after wheat withdrawal from the diet. Additional difficulty in diagnosing celiac in tropical countries like India includes confounding factors of malnutrition and parasitic infestations like giardia. Serological tests like antigliadin antibodies (IgG and IgA), anti-reticulin antibodies and endomysial antibodies have shown some promise in screening and definitive evaluation of the disease. Gluten free diet gives dramatic results.

Abstract
OBJECTIVE To study the clinical spectrum and management of choledochal cyst in children below 12 years of age. DESIGN Descriptive study. SETTING Tertiary care hospital. METHODS Twenty three children with choledochal cysts were managed between January 1991 to September 1997 and their clinical details, investigations and management were recorded. Choledochal cyst was diagnosed by ultrasonography and confirmed by ERCP or peroperative cholangioram (POC) Children were treated with antibiotics and/or percutaneous transhepatic biliary drainage if there was cholangitis and subsequently subjected to surgery (excision of the cyst and jejunal loop interposition hepaticoduodenostomy). RESULTS The median age of these children was 3 years with an almost equal sex ratio. Predominant presentation was jaundice in 18, pain abdomen in 15, fever in 12, and lump abdomen in 9 cases. The classical triad of jaundice, pain and lump was present in only 4 cases. ERCP conducted in 7 and POC in 14 cases yielded positive findings in all. Clinically there were two distinct forms of presentation: (i) infantile form (< or = 1 year) comprised 9 infants which presented with jaundice in all, acholic stool in 6, lump abdomen in 4 but only one had classical triad; and (ii) childhood form (> 1 year) presented with pain abdomen in 12 and jaundice and cholangitis in 9 subjects each. Type I cyst was seen in 20 and type IVa in 3. Two children refused surgery, and the rest underwent surgery. Three infants died after surgery, the remaining 18 were alive and well on follow-up (median 25 months). Secondary biliary cirrhosis was seen in 6, extra hepatic biliary artresia in 2 and congenital hepatic fibrosis in 1 on histology. CONCLUSIONS Choledochal cysts present in two clinically distinct forms. Infantile form is an important cause of cholestasis of infancy. Early diagnosis and referral is essential to prevent complications and death, and prognosis after surgery is good.

Abstract
OBJECTIVES We studied the clinical spectrum, histology, and malignant potential of colonic polyps in Indian children (< or =12 yr). METHODS Two hundred thirty-six children with colonic polyps were studied from January 1991 to October 1996. They were evaluated clinically and colonoscopic polypectomy was done. Children with five or more juvenile polyps were labeled as having juvenile polyposis and serial colonoscopic polypectomies were done every 3 wk. Colectomy was performed when there were intractable symptoms or clearing of the polyps by colonoscopy was not possible. Histological examination of the polyps was done. Follow-up colonoscopy was done in children with juvenile polyposis only. RESULTS The mean age of these children was 6.12 +/- 2.7 yr, with a male preponderance (3.5:1). Rectal bleeding of a mean duration of 14 +/- 16 months was the presenting symptom in 98.7%. Solitary polyps were seen in 76%, multiple polyps in 16.5%, and juvenile polyposis in 7% (n = 17) of the children. A majority (93%) of the polyps were juvenile and 85% were rectosigmoid in location. Adenomatous changes, seen in 11%, were more common in juvenile polyposis (59%) than in juvenile polyps (5%). Among those with juvenile polyposis, colon clearance was achieved in eight, six required colectomy for intractable symptoms, and three were still on the polypectomy program. Polyps recurred in 5% of children with juvenile polyps and 37.5% of those with juvenile polyposis. CONCLUSIONS Juvenile polyps remain the most common colonic polyps in children. A significant number of cases of polyps are multiple and proximally located, which emphasizes the need for total colonoscopy in all. Juvenile polyps should be removed even if asymptomatic because of their neoplastic potential. Colonoscopic polypectomy is effective even in juvenile polyposis. Surveillance colonoscopy is required in juvenile polyposis only.

Abstract
The clinical profile, malignant potential, and management of 17 children with juvenile polyposis (more than five juvenile polyps) were evaluated clinically and endoscopically. Colonoscopy and polypectomy were done three weekly until colonic clearance was achieved, and thereafter two yearly. All polyps were subjected to histological examination. Mean age was 7.7 years, with a male preponderance (3:1). Presentation was with rectal bleeding (94%), pallor (65%), stunted growth (53%), and oedema (47%), and the mean (SD) duration of symptoms was 33 (27) months. None had a positive family history or any congenital anomaly. Two children had six polyps up to the transverse colon; the rest had numerous polyps all over the colon. All children had juvenile polyps on histology and 10 (59%) had adenomatous changes (dysplasia). Total colectomy was done in six for intractable symptoms. Colon clearance was achieved in eight after an average 3.4 polypectomy sessions, and three were still on the polypectomy programme. In conclusion, juvenile polyposis is commonly associated with low grade dysplasia. Serial colonoscopic polypectomy is effective but colectomy is required for intractable symptoms and when clearance of the colon is not possible.

Abstract
BACKGROUND A juvenile polyp is a commonly seen condition in the pediatric age group as an etiological factor for rectal bleeding. The histological appearance was considered to be nonneoplastic and was distinguished from other neoplastic polyps. But this concept has been changing over the years as higher incidence of colonic and rectal adenocarcinomas are seen in patients with both familial and nonfamilial polyposis. The malignant potential was first recognized in 1980. METHODS With this background knowledge, the authors carried out a retrospective study of juvenile polyposis patients, who underwent full-length colonoscopy and upper gastrointestinal endoscopy to assess the presence of dysplastic epithelium. There were eleven cases of nonfamilial juvenile polyposis (one case with foregut polyps). RESULTS Ten cases showed presence of dysplastic epithelium in focal areas in the juvenile polyps, mild in degree in three cases and moderate in degree in 10 cases, with focal severe degree in two. CONCLUSION All polyps of juvenile polyposis after polypectomy must be subjected to histopathologic examination to determine the presence of dysplastic/adenomatous epithelium.

Abstract
The pattern of viral markers in acute sporadic hepatitis in 329 children and those in 334 healthy school children from North West India were studied. Hepatitis A was found to be the commonest infection in sporadic cases (78 per cent). Of these, 86 per cent were under 10 years and 50 per cent less than 5 years of age. Hepatitis B was positive in 8 per cent, non-A non-B in 13 per cent, A as well as B in 1 per cent, and none had Delta virus infection. Viral markers in healthy school children showed anti-HAV IgG positivity in 96 and 85 per cent in those belonging to low and high socio-economic groups, respectively, indicating past infection. HBsAg was positive in 1 per cent of cases. Viral hepatitis is an important public health problem in children and warrants active immunization.
