We describe a case of chronic idiopathic pancreatitis associated with ulcerative colitis. Pancreatitis is a rare extra-intestinal manifestations of inflammatory bowel disease. Chronic idiopathic pancreatitis associated with ulcerative colitis are usually painless, without calcification, with stricture of the main pancreatic duct and with severe exocrine pancreatic insufficiency.
Hepatitis E virus (HEV) is the worldwide leading cause of non-A non-B enterically transmitted hepatitis, and affects most commonly the population in developing countries. Cases outside this area, are nearly always imported, although apparent local acquisition has been occasionally reported. We assisted three patients with acute HEV hepatitis, confirmed by the presence of serum anti-HEV IgM. One of them did not report travelling outside of Spain in the previous years. HEV has to be included in the differential diagnosis of acute non-A non-B non-C hepatitis, even in cases in which an exposure in endemic areas cannot be recalled.

Bronchobiliary fistula is a rare condition, defined by the presence of a passage between the biliary tract and the bronchial tree. Many conditions can give rise to the development of such a communication. Biliary lithiasis is one of those and is perhaps the one most amenable to endoscopic management. We describe a case of bronchobiliary fistula secondary to the development of choledocholithiasis in a cholecystectomized patient. The clinical suspicion was raised by the presence of bilioptosis (bile-stained sputum), and the diagnosis established by endoscopic retrograde cholangiopancreatography. The patient was submitted to endoscopic sphincterotomy and stone extraction, achieving frank clinical alleviation. This case gives us the chance to review bronchobiliary fistulas secondary to biliary lithiasis, placing particular emphasis on the opportunities of endoscopic management.

We describe a patient with rapidly progressive pneumonia and a high level of serum lactate dehydrogenase, in whom postmortem study revealed the presence of a diffuse, small and large-cell multicentric non-Hodgkin's lymphoma, together with an invasive pulmonary aspergillosis. Aspergillosis is rare as a presenting feature of a lymphoproliferative disease; only one previous case has been reported to the best of our knowledge. Invasive aspergillosis and lymphoma should be considered in patients presenting with pneumonia and high level of lactate dehydrogenase.

The presence of antibody to hepatitis C virus was determined in 316 HBsAg-negative patients with non-alcoholic chronic hepatitis who did not receive any blood transfusion once the diagnosis was made. A titre of antinuclear antibodies of 1/40 or lower was found in 18 patients. Persistent chronic hepatitis was present in 21 patients, active chronic hepatitis in 145, hepatic cirrhosis in 128, and hepatocarcinoma in 22 patients. One hundred and three patients had previously received blood transfusion, 76 had undergone previous surgery without transfusion, a clinical episode of hepatitis could be traced in 14, 13 patients were drug addicts (all of them HIV negative), 1 patient had received multiples injections, another had been treated with acupuncture, and 108 patients were free of any of the above. Anti-HCV was present in 76.6% of patients; a significantly higher proportion (87.4%) was found among patients who had received blood transfusion than in patients with previous surgery (72.4%) (p = 0.012), clinical hepatitis (57.1%), or without previous hepatic disease (70.3%) (p = 0.003). The incidence of anti-HCV was lower among cirrhotics (70.3%) than in patients with active chronic hepatitis (84.1%) (p = 0.006); in contrast, previous blood transfusion was significantly higher (p = 0.001) among the latter (40.7%) than in cirrhotics (21.9%). The incidence of anti-HCV was similar among patients with (78.6%) and without (75.8%) type B infection. Our results suggest that infection with virus C may account for a high proportion of non-alcoholic non-B chronic hepatitis.
