1/4. 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.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
2/4. Case report: unusual presentation of Fasciolopsis buski in a Vietnamese child.A Vietnamese child presented with a history of abdominal pain. Shortly afterwards, he vomited eight live trematode flukes that were collected and morphologically identified as Fasciolopsis buski. The identification was confirmed by dna analysis. adult worms of F. buski from humans are very rarely seen except at autopsy, and this is the first such report from vietnam.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
3/4. Cytologic diagnosis of liver fluke infestation in a patient with subsequently documented cholangiocarcinoma.In a 32-year-old Laotian immigrant who presented with a two-day history of vomiting, abdominal pain and jaundice, ultrasound examination revealed a posthepatic obstruction. Characteristic parasitic ova were present in bile fluid submitted for cytologic evaluation. Subsequent biopsy of the patient's bile duct lesion revealed a coexistent cholangiocarcinoma. The life cycles of clonorchis sinensis and Ospisthorchis viverrini are reviewed along with the clinical and pathologic complications of infestation by these parasites in humans. The cytologic features of liver fluke infestation are characteristic and should be appreciated, as should the importance of its early diagnosis in the prevention of bile duct neoplasms.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
4/4. Locally acquired Brachylaima sp. (Digenea: Brachylaimidae) intestinal fluke infection in two South Australian infants.eggs of a small intestinal trematode were found in the faeces of two 21-month-old children from the same rural district of south australia who presented 18 months apart with mild abdominal pain and diarrhoea. Treatment with praziquantel resulted in egg clearance and resolution of gastrointestinal symptoms. A brachylaimid intestinal trematode involving the common house mouse, poultry and introduced European helicid snails is well established in south australia. Both infants had been seen eating raw snails, and snails from their environment were found to be infected with metacercariae of a brachylaimid trematode.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
