RESUMO

A santorinicele is defined as a focal cystic dilatation of the terminal portion of the dorsal pancreatic duct at the minor papilla. Most cases reported previously were associated with pancreas divisum and a santorinicele without pancreas divisum is known to be rare. We recently experienced a typical case of a santorinicele without pancreas divisum in a 67-yr-old woman with abdominal pain and hematochezia, subsequently proven to be the result of an ischemic colitis. The santorinicele was diagnosed incidentally with multi-detector row computed tomography using a minimum intensity projection technique, which clearly showed a cystic dilatation of the terminal portion of the dorsal pancreatic duct and a communication between the ventral and dorsal pancreatic ducts. This finding was also confirmed by a magnetic resonance cholangiopancreatography.

RESUMO

BACKGROUND/AIMS: Saccharomyces boulardii (S. boulardii) has been reported to be beneficial in the treatment of inflammatory bowel disease, however, little is known about its mechanism of action. Peroxisome proliferator- activated receptor-gamma (PPAR-gamma) is recently found to regulate inflammation in intestinal epithelial cells. We hypothesized that the anti-inflammatory effects of S. boulardii are mediated, in part, through PPAR-gamma. To test this hypothesis, we examined the ability of S. boulardii to modulate the expression of PPAR-gamma in human colon cells. METHODS: Effects of S. boulardii on survival and proliferation of HT-29 human colon cells were assessed by MTT and [3H]thymidine incorporation assays. PPAR-gamma expression was assessed by Western blot and RT-PCR. Induction of interleukin-8 (IL-8) expression by tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta), or lipopolysaccharide (LPS) was assessed by RT-PCR. RESULTS: S. boulardii did not affect viability and proliferation of HT-29 cells. S. boulardii up-regulated PPAR-gamma expression at both mRNA and protein levels. Pretreatment of HT-29 cells with S. boulardii blocked PPAR-gamma down-regulation by TNF-alpha, IL-1beta, or LPS, whereas it ameliorated IL-8 response to these proinflammatory factors. CONCLUSIONS: S. boulardii stimulates PPAR-gamma expression and reduces response of human colon cells to proinflammatory cytokines.

RESUMO

Primary biliary cirrhosis is a chronic progressive cholestatic liver disease of unknown cause that usually affects middle-aged women and eventually leads to cirrhosis and liver failure. It is characterized by the progressive destruction of small intrahepatic bile ducts, portal inflammation, and progressive scarring. The diagnosis is made by these characteristic pathologic findings and the presence of antimitochondrial antibody. Immunofluorescence, the most widely used method for determining antimitochondrial antibody, is less sensitive and specific than ELISA or immunoblotting and influenced by observer interpretation. Therefore, it is important to detect anti-M2 antibody, the most specific antibody of primary biliary cirrhosis, by ELISA or immunoblotting when antimitochondrial antibody is not detected by immunofluorescence method which can lead to the incorrect diagnosis as autoimmune cholangitis. We describe a case of primary biliary cirrhosis with antimitochondrial antibody negative by immunofluorescence, anti-M2 antibody positive by ELISA. We confirmed primary biliary cirrhosis by liver biopsy.
