  ABSTRACT: A nine-year-old child presented with melena and anemia. She had similar symptoms five months earlier and had undergone an extensive workup with upper gastrointestinal endoscopy and colonoscopy, both normal and 99m-Tc-RBC-scintigraphy which was positive in the right lower quadrant. This time, capsule endoscopy was performed and disclosed an hemangioma with a dark spot suggesting recent bleeding in the ileum. The lesion was resected. Pathological examination revealed a transmural cavernous hemangioma. Small bowel hemangioma is a rare disease. Its diagnosis is extremely difficult and is usually obtained during surgery. Capsule endoscopy is an endoscopic technique that can improve preoperative diagnosis, as reported in the present case.

• Article: Ulcerative colitis, primary biliary cirrhosis, and chronic pancreatitis: coincident or coexistent?

  F T Veloso, L M Dias, J Carvalho, J Fraga, J Saleiro
  [show abstract] [hide abstract]
  ABSTRACT: We report a 45-year-old woman with chronic ulcerative colitis complicated by primary biliary cirrhosis and concomitant chronic pancreatitis. The combination of primary biliary cirrhosis and ulcerative colitis has only rarely been reported, and the association of these diseases with chronic pancreatitis is even rarer. These systemic manifestations of ulcerative colitis should be looked for more often.

  [show abstract] [hide abstract]
  ABSTRACT: Autoimmune hemolytic anemia is a rare complication of ulcerative colitis. This report chronicles a patient successfully treated with steroids, and reviews treatment in previously reported cases. The fact that 21% of patients recovered with steroid therapy encourages a conservative approach before surgery is considered.

  ABSTRACT: Hepatic abscess is a rare complication of Crohn's disease. The present report describes an additional case diagnosed by CT scanning and successfully treated by surgery. Recognition of this complication is important because early therapy could improve the prognosis.

  [show abstract] [hide abstract]
  ABSTRACT: Spontaneous umbilical fistula developed in two young women with Crohn's disease. This peculiar complication of Crohn's disease has been rarely reported. In view of the complete closure of the fistulas with medical treatment, we recommended conservative medical management, at least initially, in such patients.

  ABSTRACT: Since 1975, 375 patients with inflammatory bowel disease (IBD) in Oporto have been studied; 180 had ulcerative colitis (UC) and 195 had Crohn's disease (CD). The steady rise in the number of patients observed suggests that the incidence of IBD is rising in the north of Portugal. At diagnosis UC was mild or moderate in 75.5% of patients, and 40.5% had rectal affection only. Colectomy was done only in two cases. The mortality was 1.1%. Clinical experience suggests that the behaviour of UC in this community may be milder than that reported at other centres. In CD patients ileitis was the commonest form (44.1%), and at diagnosis surgery was required for an acute condition of the abdomen in 22.5% of cases. The main complications were abdominal fistulae (22.1%) and perianal fistulae (21.5%). Colitis-related extraintestinal complications were present in 33.3% of IBD patients.

• Article: Macroglobulinemia and small intestinal disease. A case report with review of the literature.

  ABSTRACT: Involvement of the gastrointestinal tract in macroglobulinemia is exceedingly rare. We describe a patient with IgM biclonal immunoglobulin disorder associated with diffuse lymphoplasmacytic infiltration of the small intestine. This chronic illness was characterized by diarrhea, steatorrhea, and intestinal pseudo-obstruction. Full-thickness biopsy specimens of the jejunum showed stunted and fused villi, giardiasis, and a widespread cellular infiltrate in the lamina propria extending through the muscularis mucosae into the submucosa and muscular layers. The infiltrate had a cytologically benign appearance that was shown to be polyclonal by immunochemical stains. Intestinal vacuolated plasma cells were occasionally observed in electron microscopic study. The patient has not developed the features of Waldenstrom's disease on a clinical follow-up of 14 years.
