Numerous infectious agents may induce acute pancreatitis. We report 6 cases of Salmonella-associated acute pancreatitis. Pathogenesis of this type of pancreatitis is related to multiple factors that may coexist in the same patient. The typical clinical picture consists in epigastric pain, nausea, vomiting, diarrhoea and fever. Imaging techniques often disclose minimal changes such as moderate swelling of a part or of the totality of pancreas. As outcome is usually good, conservative treatment and antibiotics may be sufficient to ensure recovery.

Cholelithiasis and gastroesophageal reflux are both very common diseases that may occur simultaneously. Management of asymptomatic gallstones is still controversial. Because severe complications due to gallstones may occur incidental cholecystectomy during nonrelated abdominal surgery may be offered to patients with coexisting gallbladder disease. The aim of this study was to assess the clinical outcome of patients after laparoscopic fundoplication and incidental cholecystectomy for cholelithiasis compared with the outcome of patients after fundoplication alone. We conducted a retrospective chart review and prospective analysis using a questionnaire of the clinical outcome of patients who underwent laparoscopic fundoplication and incidental cholecystectomy from June 1991 to January 2000 in comparison with sex- and age-matched patients who had antireflux surgery alone. Sixty-seven (6.3%) of 1065 patients had a laparoscopic cholecystectomy at the time of laparoscopic antireflux surgery; 101 (75%) of 134 answered the questionnaire. The mean follow-up time was 4.6 years. Laparoscopic cholecystectomy did not influence surgical morbidity or mortality. Postoperative symptom score (1-10) did not show a statistically significant difference regarding bloating, diarrhea, abdominal pain, nausea, vomiting, biliary problems, jaundice, pancreatitis, dysphagia for liquids and solid, heartburn, regurgitation, and chest pain when the two groups were compared. We conclude that incidental cholecystectomy during laparoscopic antireflux surgery is safe and does not appear to influence the clinical outcome of the antireflux procedure.

Valproic acid is a widely used drug in the treatment of epilepsy and, compared to other anticonvulsant drugs, is considered safe. The most common side effects of valproic acid ingestion or therapy are transient nausea, vomiting, abdominal cramps, and diarrhea. Most of these complaints are mild. However, more serious adverse reactions can occur such as hepatotoxicity and pancreatitis. It has been proposed that, whenever possible, valproic acid not be used in the younger child, the child with a severe seizure disorder or other neurological disorders, mental retardation, developmental delay, organic brain disease, congenital abnormalities, or the child who is taking multiple anticonvulsant drugs, as these factors may increase the likelihood of hepatotoxicity and/or pancreatitis. In the present report, we describe a fatal case of acute hemorrhagic pancreatitis in a four and a half-year-old Hispanic female child who was receiving valproic acid in combination with another anticonvulsant drug for control of focal seizures. The patient also received the macrolide antibiotic azithromycin. For pediatricians and forensic pathologists valproic acid-induced pancreatitis can be a challenging diagnosis which must not be mistaken for abdominal trauma. We discuss the workup of the patient and differential diagnosis.

Endoscopic retrograde cholangiopancreatography (ERCP), together with its substantial therapeutic capabilities, carries a higher potential for complications than other endoscopic procedures. Common major complications specific to pancreaticobiliary instrumentation include pancreatitis, post-sphincterotomy hemorrhage, perforation, and cholangitis with or without systemic sepsis. Two patients underwent therapeutic ERCP for recurrent episodes of abdominal pain and elevation of hepatobiliary enzymes. Endoscopic sphincterotomy was difficult and prolonged. The calculi were successfully extracted by sweeping the choledochus with a balloon-tipped catheter or basket in both cases. The patients experienced postprocedure diffuse abdominal pain unassociated with nausea or vomiting. Laboratory data showed normal serum amylase and lipase 2, 6, and 18 h after the end of procedure, a fall in hematocrit level, and an increase of indirect bilirubin and lactic dehydrogenase. The abdominal pain subsided in 4 to 6 h. The hematocrit level remained stable during the next 3 days, and the patients were very well when discharged. Examination of glucose-6-phosphate dehydrogenase (G-6PD) enzyme levels in red cells 20 days later showed complete enzyme deficiency. This report highlights the importance of examining G-6PD deficiency in patients with post-ERCP abdominal pain, normal serum amylase and lipase, and laboratory findings of hemolysis.

A 35-year-old female who had previously undergone an open gastric bypass, underwent elective caesarian section and ventral hernia repair, complicated by a double closed-loop obstruction with resulting gastric perforation. Back pain and anemetic nausea predominated, as proximal bowel and pancreatobiliary obstruction followed an afferent limb volvulus. Pancreatitis, cholangitis, and gastric perforation ensued, leading to intraabdominal sepsis. This rare situation must be recognized as a potentially serious complication of gastric bypass surgery, and requires prompt recognition and aggressive surgical correction.

Systemic lupus erythematosus presenting as acute pancreatitis is rare. We report a case of a 12-year-old girl with a 1-year history of systemic lupus erythematosus who developed active pancreatitis. The pancreatitis was first manifested by nausea, vomiting, fever, and abdominal pain. Elevated serum amylase (578 U/L) and lipase levels (5588 U/L), and pancreatic enlargement on ultrasound and computerized tomography confirmed the diagnosis. She responded well to high-dose corticosteroid. The high titer of antinuclear antibodies (1:1280) and low level of complement components (C3, 42.9 mg/dL; C4, 2.3 mg/dL) during the pancreatitis attack suggested that the pancreatitis may have been due to systemic lupus erythematosus exacerbation and not related to drug therapy.

A fifty-year-old man complained of abdominal pain, nausea, loss of appetite, postprandial vomiting and loss of weight. Abdominal sonography revealed a chronic calcifying pancreatitis with a tubular stenosis of the common bile duct, dilatation of the pancreatic duct and multiple pancreatic duct stones. Distal of the pylorus there was an intramural pseudocyst, which had led to the obstruction of the duodenal lumen. Shortly after the ultrasound examination abdominal pain increased. In addition, an elevation of serum lipase levels was noted, but reclined rapidly the next day and was normalized a few days later. The patient was well the next morning, the symptoms of gastric retention disappeared and he had a good appetite. A CT of the abdomen two days later showed the chronic pancreatitis but could not confirm the pseudocyst and a subsequent repeat sonography revealed only a remnant of the pseudocyst. In conclusion it can be assumed that the intramural pseudocyst ruptured when pressure was applied with the ultrasound transducer to displace interfering colonic gas. Although it cannot be advised as a treatment measure for a pseudocyst, regression of a pseudocyst due to emptying into the gastrointestinal tract has to be expected.

Lactic acidosis (LA), a rare but life-threatening adverse effect associated with antiretroviral therapy, has been reported with an increasing frequency since the mid-1990s. From June 1994 to June 2002, a total of six patients, four males and two females with a median age of 43 years (range, 30 to 74 years), had been diagnosed with LA. The estimated incidence of LA was 5.1 per 1000 patient-years (PYs) on highly active antiretroviral therapy (HAART) (95% confidence interval [95% CI], 4.5-5.5 per 1000 PYs) and 4.4 per 1000 PY on nucleoside analogues (NAs) (95% CI, 3.9-4.7 per 1000 PYs). Their median body mass index at diagnosis of LA was 17.6 kg/m(2) (range 16.3 to 22.6 kg/m(2)). The median CD4+ lymphocyte count at the initial diagnosis of HIV infection and at the onset of LA was 38 cells/ micro L (range, 4 to 103 cells/ micro L) and 108 cells/ micro L (range, 79 to 224 cells/ micro L), respectively. The most common symptoms were nausea, vomiting, and dyspnoea. All of the patients had findings suggestive of NA-related mitochondrial toxicity, such as myositis, pancreatitis, fatty hepatitis, peripheral neuropathy or lipodystrophy. The prescribed NA related to LA were stavudine in six patients, lamivudine, five, and didanosine, one. Despite treatment, all patients died of persistent circulatory collapse following LA. The median duration from diagnosis to death was eight days (range, 4-17 days). Our report highlights that clinicians caring for patients with AIDS should be alerted to the potentially fatal LA associated with antiretroviral therapy when patients present with low body mass index, lipodystrophy, unexplained abdominal symptoms, dyspnoea, or elevated aminotransferases.

Lupus cystitis was rare but frequently resulted in obstructive uropathy and had a strong association with gastrointestinal (GI) symptoms. We treated six patients with systemic lupus erythematosus (SLE) and obstructive uropathy from January 1996 to December 2001 in a university hospital. Evidence of cystitis was obtained from cystoscopic biopsy or the presence of thickened bladder wall in image study. Similar to other reports, five patients had GI manifestations such as abdominal pain, nausea/vomiting, diarrhoea or ileus. In addition, mesenteric lymphadenopathy or pancreatitis was noted in three patients. Two patients had been treated for idiopathic thrombocytopenic purpura (ITP), four and 20 years ago, respectively. All six patients had antibodies to double-stranded DNA (dsDNA). Five patients each had antibodies to cardiolipin (IgG aCL) or SSA. The high prevalence of anti-SSA had also been reported in Chinese lupus patients with intestinal pseudo-obstruction, a clinical manifestation frequently associated with bilateral ureterohydronephrosis. Two patients died of intractable infection after the surgical procedures for persistent ureterohydronephrosis and both patients had antibodies to ribosomal P proteins. Lupus cystitis might not be so rare in Chinese patients with SLE. The diagnosis should be kept in mind when lupus patients have urinary and/or GI symptoms.

Acute pancreatitis is a rare complication of interferon (IFN) and ribavirin (RBV) therapy. The aim of this study was to determine the incidence, clinical presentation, and outcome of acute pancreatitis in patients with chronic hepatitis C virus (HCV) infection treated with IFN and RBV combination therapy. We conducted a retrospective review of 1706 HCV-infected patients treated with IFN alpha-2b and RBV. The diagnosis of drug-induced acute pancreatitis was made based on the presence of epigastric pain, elevated amylase and lipase levels, and the absence of other identifiable causes of pancreatitis. Acute pancreatitis was diagnosed in 7 of 1706 HCV-infected patients (0.4%; 95% CI, 0.2 to 0.8%) who were treated with IFN alpha-2b and RBV. The mean age of the patients (four males and three females) was 51.4 +/- 4.7 years and the median duration of therapy prior to development of pancreatitis was 12.0 weeks (range, 4.0-21.0 weeks). All patients presented with epigastric pain associated with nausea, vomiting, and/or fever. The median amylase and lipase values at the time of diagnosis of pancreatitis were 330.0 U/L (range, 182.0-1813.0 U/L) and 500.0 U/L (range, 171.0-2778.0 U/L), respectively. IFN and RBV were discontinued in all patients at the time of diagnosis and six of the seven patients were hospitalized; one patient refused hospital admission. Pancreatitis resolved in all seven patients and none of these individuals had recurrent pancreatitis during a median follow-up of 18.0 months (range, 3.0-27.0 months). In conclusion, IFN and RBV combination therapy is a potential cause of drug-induced pancreatitis in patients with chronic HCV. In these individuals, pancreatitis is often severe enough to warrant hospital admission, although symptoms resolve promptly after discontinuation of antiviral therapy.
