We determined the amylase levels in serum samples from six callitrichid species. The normal serum amylase values for all of these species was within or higher than the normal human range. Amylase values higher than the normal range occurred not only in association with pancreatitis but also pyometra, bone fracture, abscesses, diabetes mellitus and gastrointestinal conditions leading to diarrhea. We concluded that although serum amylase activity may be helpful in diagnosing pancreatitis, it is, as in humans, not specific for this condition in callitrichids.

A total of 25 patients with metastatic renal cancer were treated on a phase II protocol with 5 days of continuous-infusion fluorodeoxyuridine (FUDR), (0.1 mg/kg daily) together with high-dose oral leucovorin (100 mg 4 h) and daily x6 high-dose interferon-alpha 2b (30 x 10(6) IU/m2). Despite the good performance status of the patients and the inclusion of 14 previously untreated patients in the cohort, no response was observed among the 20 evaluable patients. Toxicities included high fever, moderate anemia, transient leukopenia, transient and mild elevations of transaminases, and moderate to severe nausea, vomiting, diarrhea, and mucositis. There were also two episodes each of confusion, fluid retention, and pancreatitis and one episode of increased creatinine levels. During the study three deaths occurred, two of which were possibly therapy-related. Despite previous reports of activity of FUDR in metastatic renal cancer, the present regimen cannot be recommended.

Myelosuppression is associated with human immunodeficiency virus (HIV) infection and may also be produced by agents used for the treatment of the disease or the treatment of its complications. Didanosine (ddl; 2',3'-dideoxyinosine) is a newer purine nucleoside that has recently become available for therapy for HIV infection. The effects of didanosine on peripheral blood counts have been retrospectively evaluated in the first 170 patients treated with this new agent in four phase I trials. Patients treated with didanosine showed statistically significant improvements in hemoglobin levels, white cell counts, and granulocyte and platelet numbers as compared with baseline values. These changes were seen with or without prior therapy with zidovudine, were somewhat more pronounced at higher doses of didanosine, and persisted for up to 1 year. Reported adverse events included peripheral neuropathy, diarrhea, and most notably, pancreatitis. It is concluded that, while some toxic side effects occur, didanosine therapy in HIV infection is associated with an amelioration of HIV-induced myelosuppression.

From April 1988 until November 1990, 83 patients with symptomatic gallbladder stones were treated in the University Hospital "Dijkzigt" Rotterdam with extracorporeal shock wave lithotripsy (ESWL) followed by oral administration of bile acids (urso- and chenodeoxycholic acid). According to our inclusion criteria, patients with up to 10 stones without any limit to the size of the stone(s) were accepted for treatment. On average, these patients underwent two sessions of ESWL with an electromagnetic lithotriptor (Lithostar and Lithostar Plus, Siemens AG, Erlangen, Germany). Fragmentation of stones was achieved in 70/83 (84% patients). The best results were achieved in patients with a solitary gallstone (50% of these patients were stone-free 12 months after ESWL). Four percent of the patients with two to three stones, and 12% of the patients with four to 10 stones were free of stones 12 months after ESWL. Twenty-eight (34%) patients suffered from biliary colics after ESWL, and three patients (3.5%) developed pancreatitis. The administration of oral bile acids was complicated by transient diarrhoea in 15 (18%) patients. ESWL followed by oral bile acid therapy is a relatively effective and safe therapy for a highly select population of patients with gallbladder stones, which can be performed on an outpatient basis. Although the results for multiple stones were poor, the usage of wide inclusion criteria (up to 10 stones of any size) did not affect the success rate of ESWL for multiple stones.

Cytomegalovirus (CMV) pancreatitis was diagnosed in eight out of 124 pancreatic transplant recipients. Five of the eight patients developed intrapancreatic abscesses and four of the grafts were lost, but one is still functioning. In the three additional cases of pancreatitis, antiviral treatment with foscarnet or ganciclovir was given as soon as signs of CMV pancreatitis were detected. No such grafts were lost during the acute phase. CMV infection was diagnosed in cells from pancreatic juice, by virus isolation, detection of CMV antigen in cells from pancreatic juice or by CMV serology. The signs and symptoms of CMV pancreatitis included fever, general malaise, abdominal pain, diarrhoea, localized peritonitis, hyperamylasaemia, leukopenia and hyperglycaemia. It is recommended that rapid diagnostic procedures for CMV should be carried out when early signs of pancreatitis develop in pancreatic graft recipients. Antiviral treatment should be given when CMV pancreatitis is suspected or diagnosed in order to prevent the development of intrapancreatic abscesses and graft loss.

A retrospective study of 76 children with hemolytic uremic syndrome (HUS) who were admitted to the Alberta Children's Hospital in Calgary. Alberta between January 1982 and December 1988 was undertaken to explore the gastrointestinal manifestations of the syndrome. The children (mean age of 4.0 +/- 3.1 years) presented primarily during the summer months with a microangiopathic hemolytic anemia (Hgb 94 +/- 26 g/L), thrombocytopenia (platelets 87 +/- 83 X 10(9)/L), and acute renal failure (oligoanuria with a BUN of 26 +/- 15 mmol/L, and a creatinine of 294 +/- 90 mumol/L). Forty-three children required dialysis for 10 +/- 17 days. The duration of hospitalization was 17 +/- 17 days. Four children died of complications attributable to HUS. The following symptoms and gastrointestinal manifestations of HUS were noted: fever (33%), vomiting (80%), abdominal discomfort/tenderness (59%), diarrhea (100%), hemorrhagic colitis (79%), rectal prolapse (13%), colonic stricture (3%), colonic perforation (1%), intussusception (1%), indirect hyperbilirubinemia (49%), and elevated hepatocellular enzymes (58%). Of the last 29 children studied, 19 (66%) had elevated levels of amylase and lipase in the presence of acute renal failure, and six (21%) had a marked elevation of lipase (more than four times normal) with additional supportive evidence of pancreatitis. The additional supportive evidence included persistent elevation of lipase after the resolution of acute renal failure in four children, a marked increment in lipase in association with abdominal pain and an abnormal ultrasound of the pancreas after the initiation of oral feeding in a fifth child, and pancreatic exocrine and endocrine necrosis at autopsy in a sixth child.(ABSTRACT TRUNCATED AT 250 WORDS)

Nine children with acute typical post-diarrhea hemolytic uremic syndrome (HUS) were treated with intravenous gammaglobulin (IVIG). These children were compared to nine children with HUS who did not receive IVIG. The use of IVIG did not appear to have a beneficial effect on eight of the nine treated children. There were no significant differences found in the duration of hemorrhagic colitis, thrombocytopenia, elevation of the white blood count (WBC), anuria, dialysis, or hospitalization, or the presence of a central nervous system complication or pancreatitis. Although no significant difference was found in the duration of thrombocytopenia, there was a trend towards a longer duration of thrombocytopenia in children treated with IVIG (P = 0.13). One child demonstrated both an increase in her platelet count and a decrease in her WBC count within 24 h of receiving her first dose of IVIG.

The role of operative intervention for hereditary pancreatitis, a rare form of chronic parenchymal destruction, is unclear. To determine whether surgical therapy is safe and provides prolonged symptomatic relief, the authors reviewed the management of 22 adults (11 men, 11 women) with hereditary pancreatitis treated surgically between 1950 and 1989. Hereditary pancreatitis was defined as a family history of two or more relatives with pancreatitis and clinical, biochemical, or radiologic evidence of pancreatitis. The mean ages at onset of symptoms and at operation were 15 years (range, 3 to 52 years) and 31 years (range, 18 to 54 years), respectively. Pain was the primary indication for operation in all patients. Additional symptoms included nausea, vomiting (73%), weight loss (55%), and diarrhea (41%). Ductal dilatation was present in 68%, pancreatic parenchymal calcifications in 73%, pseudocysts in 36%, and splenic vein thrombosis in 18%. Primary operations included ductal drainage in 10 patients, pancreatic resection alone in three, resection with drainage in three, cholecystectomy plus sphincteroplasty in two, cholecystectomy with or without common bile duct exploration in two, pancreatic abscess drainage in one, and pseudocyst drainage in one. There were no perioperative deaths, and the morbidity rate was 14% (intra-abdominal abscess, wound infection, and urinary tract infection). Symptoms recurred in nine patients. Severity prompted reoperation in five. Secondary operations included pancreatic resection in three, pseudocyst excision in one, and pancreaticolithotomy in one. Follow-up to date is complete and extends for a median of 85 months. Eighteen patients (82%) are clinically improved or asymptomatic. Symptoms have persisted in four patients, and two patients have died of pancreatic carcinoma. Two patients died of unrelated causes. Surgical therapy for patients with hereditary pancreatitis selected on the basis of the traditional indications for surgical treatment of chronic pancreatitis is safe and efficacious.

The pathologic changes associated with human cryptosporidiosis have not been well characterized. In this report, 15 cases of cryptosporidiosis in acquired immunodeficiency syndrome patients are described. Organisms were found in autopsy tissue specimens in 13 cases, and only in antemortem stool samples in two. Gastrointestinal/hepatobiliary distribution of organisms was as follows: small intestine (13 cases), extrahepatic bile ducts (eight), intrahepatic bile ducts (seven), large intestine (six), pancreas (five), stomach (three), and esophagus (one). At all sites, infection was usually associated with nonspecific reactive epithelial changes, architectural abnormalities such as villous flattening in the small intestine, and interstitial edema with mixed inflammatory cell infiltrates. Presence of organisms and associated mucosal injury were patchy and of variable severity in the intestine. In the biliary tract, injury was commonly diffuse and severe. Pancreatic duct injury was generally mild and often limited to hyperplastic squamous metaplasia. In late-stage acquired immunodeficiency syndrome patients with cryptosporidiosis, widespread infection in the gastrointestinal and biliary systems by this coccidian was more common and severe than previously suggested. Although the mechanisms have yet to be determined, infection usually is accompanied by pathologic changes that may be causally related to pathophysiologic abnormalities, such as diarrhea and malabsorption, and may account for other clinical manifestations of pancreatitis, cholangitis, and obstructive cholestasis.

Significant differences exist in the prevalence of most gastroenterological emergencies in tropical compared with temperate countries. Both ethnic and environmental (often clearly defined geographically) factors are relevant. The major oesophageal lesions which can present acutely in tropical countries are varices and carcinoma; bleeding and obstruction are important sequelae. Peptic ulcer disease (and its complications), often associated (not necessarily causally) with Helicobacter pylori infection, has marked geographical variations in incidence. Emergencies involving the small intestine are dominated by severe dehydration, and its sequelae, resulting from secretory diarrhoea, most notably cholera. However, enteritis necroticans ('pig bel' disease), paralytic ileus (sometimes caused by antiperistaltic agents) and obstruction (secondary to luminal helminths, volvulus and intussusception) are other important problems, especially in infants and children. Enteric fever is occasionally complicated by perforation and haemorrhage; the former (which is notoriously difficult to manage) is accompanied by significant mortality. Ileocaecal tuberculosis is a major cause of right iliac fossa pathology--sometimes associated with malabsorption; amoeboma is an important clinical differential diagnosis. The colon can be involved in invasive Entamoeba histolytica infection (which, like complicated enteric fever, is difficult to manage if the fulminant form, with perforation, ensues), shigellosis, volvulus and intussusception. Acute colonic dilatation occasionally follows Salmonella sp., Shigella sp., Campylobacter jejuni, Yersinia enterocolitica and rarely E. histolytica infections. Acute hepatocellular failure is a major cause of morbidity and mortality in the tropics and subtropics. It usually results from viral hepatitis (HBV, sometimes complicated by HDV, and HCV), but there is a long list of differential diagnoses. Hepatotoxicity resulting from herbs, chemotherapeutic agents or alcohol also occurs not infrequently. Chronic liver disease and its sequelae (often long-term results of viral hepatitis) are commonplace. Haematemesis and hepatocellular failure are usually very difficult to manage due to a lack of sophisticated support techniques in developing countries. Invasive hepatic amoebiasis usually responds well to medical management; however, spontaneous perforation can occur and the consequences of this are serious. Pyogenic liver abscess, although far less common than amoebic 'abscess', carries a bad prognosis whatever the method(s) of management. Hydatidosis and schistosomiasis also involve the liver, and helminthiases are important in the context of biliary tract disease. Gall stones are unusual in most tropical settings. Acute pancreatitis is overall unusual, but chronic calcific pancreatitis can present as an acute abdominal emergency.
