1/32. An incidental case of human Heterophyes nocens infection diagnosed by sectional morphology in a biopsy specimen of the small intestine.

    A case of human infection with Heterophyes nocens (heterophyidae) was incidentally found in a biopsy specimen of the Meckel's diverticulum at the upper part of the small intestine. The patient was a 58-year-old man living in a rural area of Talsonggun, Kyongsangbuk-do. He had gastrointestinal symptoms such as epigastric pain, indigestion, and abdominal discomfort for 3 months, and severe diarrhea, abdominal pain, and vomiting for about 1 month before hospitalization. endoscopy of the upper part of the small intestine revealed a Meckel's diverticulum, and it was excised and histopathologically examined. Three adult flukes were incidentally found sectioned in the mucosa, and they were identified as H. nocens. The patient had a history of eating raw mullets at a fish market in Pusan 6 months ago, and the mullets were presumed to be the source of infection. This case brings a considerable interest in that specific diagnosis of heterophyid infections could be done by sectional morphology of the worms.

2/32. Ultrasonographic appearance of colon taeniasis.

    We present the case of a 50-year-old woman with abdominal pain, nausea, loss of appetite, and frequent stools in whom the routine ultrasonographic examination demonstrated a double-reflective, ribbon-like structure in the lumen of the initial segment of the ascending colon, which suggested colon taeniasis. Because the initial parasitologic analysis yielded negative results and application of albendazol did not have any therapeutic effect, the diagnosis was confirmed by barium enema and subsequently by parasitologic examination of proglottids passed in the stool after application of niclosamide. The double-reflective, ribbon-like structure in the lumen of the intestine seems to be specific to the ultrasonographic appearance of intestinal taeniasis. Transcutaneous ultrasonography of the gastrointestinal tract, performed as a screening method before conventional radiologic or endoscopic examination, can point to the ultimate diagnosis of colon taeniasis.

3/32. Hepatobiliary and pancreatic complications of ascariasis in children: a study of seven cases.

    OBJECTIVES: This study presents seven cases of severe hepatobiliary and pancreatic complications of ascariasis in children. The authors describe the clinical, laboratory, and imaging findings, as well as the patients' clinical evolution. methods: These cases were studied within a period of approximately 1 year and included children younger than 11 years (mean age, 4.4 years). The authors reviewed their medical history and evaluated the results of their main diagnostic examinations. RESULTS: All of the patients had vomiting, abdominal pain, pallor, and abdominal distension at presentation. Passage of ascaris lumbricoides in stool occurred in five cases, emesis with worms in three, fever in three, and hepatomegaly in two. Five patients had pancreatitis, of which two were necrohemorrhagic and one had pseudocyst of the pancreas. In three patients, A. lumbricoides was present in the pancreatic duct. Two patients had hepatic abscess (28.6%), and one of them also had cholangitis. One of the patients with pancreatitis also had signs of cholecystitis at presentation. CONCLUSIONS: ultrasonography was the imaging diagnostic method of choice and demonstrated the presence of A. lumbricoides in the biliary and the pancreatic ducts, as well as signs of pancreatitis, cholecystitis, and hepatic abscess. Endoscopic retrograde cholangiopancreatography, used to confirm the diagnosis, was a fundamental procedure in the treatment, allowing the removal of worms from the biliary duct in four of seven patients.

4/32. The endoscopic diagnosis of intestinal capillariasis in a child: a case report.

    A 13-year-old boy was diagnosed as having intestinal capillariasis by gastroduodenoscopy. He presented with a 10-month history of chronic abdominal pain and diarrhea. The boy had stayed in central thailand and had eaten uncooked fish and raw shellfish. Gastroduodenoscopy showed normal jejunal mucosa although histology revealed flattened villi, crypt proliferation, acute inflammation, and eosinophilic granulomata. An egg of capillaria philippinensis was also seen. The child was treated with mebendazole for 30 days. He had gained six kilograms by the time of his last follow-up.

5/32. Human intestinal anisakiosis due to consumption of raw salmon.

    Anisakiosis is a parasitic infection that follows consumption of raw or insufficiently pickled, salted, smoked, or cooked wild marine fish infected with anisakis sp. larvae. We report a case of intestinal anisakiosis in a 50-year-old man from quebec who presented with abdominal pain and peripheral eosinophilia after eating raw wild-caught salmon from the pacific ocean off canada. Abdominal CT scan showed bowel distension proximal to a segmental jejunal wall thickening, which was resected. The jejunum segment showed a localized area of serositis with mucosal edema and a submucosal abscess rich in eosinophils surrounding a parasite consistent with the third larval stage of anisakis sp. Diagnostic morphologic characteristics included an unpaired excretory gland (renette cell), Y-shaped lateral epidermal cords, no apparent reproductive system, and a ventriculus (glandular esophagus). These features and the absence of lateral alae excluded Ascaris sp. The absence of ventricular appendage and intestinal cecum excluded other anisakids of the genera Pseudoterranova and Contracaecum. As the popularity of eating raw fish is growing in north america, anisakiosis may be diagnosed more frequently in surgical specimens. This parasitic infection should be considered in the differential diagnosis of acute abdominal syndromes and eosinophilic infiltrates of the stomach, small intestine, colon, omentum, and mesentery, especially with a history of raw marine fish consumption.

6/32. oesophagostomiasis in man: report of the first Malaysian case with emphasis on its pathology.

    This paper describes the first Malaysian case of oesophagostomiasis. The patient was an 8-year-old Malay boy who presented to Ipoh General Hospital, Perak with abdominal pain and weight loss. Examination revealed multiple cavitated pseudotumours of the colon. A hemicolectomy was performed. Examination of the lesions revealed oesophagostomum worms in the necrotic centres. The differential diagnoses and the pathology caused by oesophagostomum are discussed. A brief review of the available literature is presented.

7/32. Intestinal enterocytozoon bieneusi microsporidiosis in an hiv-infected patient: diagnosis by ileo-colonoscopic biopsies and long-term follow up.

    A 39-year-old patient with acquired immunodeficiency syndrome was diagnosed as having intestinal enterocytozoon bieneusi microsporidiosis after persistent watery diarrhea for 30 months and a 16-kg weight loss. Microsporidian parasites were found by light and electron microscopy in tissue specimens of the duodenum, jejunum, and terminal ileum, and by light microscopic examination of stool specimens. When duodenal tissue sections obtained 16 months previously were reviewed retrospectively, E. bieneusi was also found. Until now, diagnosis of intestinal microsporidiosis has been based on examination of bioptic specimens of the upper small intestine because the sensitivity of new coprodiagnostic techniques has not been determined. Our findings of ileal microsporidiosis show that examination of the terminal ileum and ileal biopsy collection in tandem with colonoscopy is indicated for patients infected with human immunodeficiency virus and suffering from unexplained chronic diarrhea. The long-term course of our patient demonstrates that E. bieneusi, although not necessarily life threatening, can cause protracted debilitating diarrhea and wasting in severely immunodeficient patients.

9/32. A patient with eosinophilia, hypoalbuminemia and abdominal pain.

    strongyloides stercoralis infections frequently present with eosinophilia and abdominal pain. Since the gastrointestinal symptoms are non-specific, only 15 percent of these patients are correctly considered to have an infectious enteritis or intestinal parasite. In fact, the initial diagnosis is peptic ulcer disease in most patients. The clinical course may be indolent, or patients may develop a sudden catastrophic illness, particularly following the administration of corticosteroids.

10/32. Intestinal capillariasis (capillaria philippinensis) acquired in indonesia: a case report.

    We report a case of intestinal capillariasis in a 32-year-old Italian man. After he made a trip to indonesia that lasted approximately one month, he developed heartburn, abdominal pain, irregular bowel movements, headache, fatigue, weight loss, low-grade fever, and severe itching. The diagnosis was provided by the recovery of capillaria philippinensis eggs in the stool. Treatment with oral albendazole, 200 mg twice a day for 21 days, resulted in clinical and parasitologic cure. This is the first report of C. philippinensis infection acquired in indonesia.
