11/31. Gingivostomatitis after eating fish parasitized by anisakis simplex: a case report.

    anisakis simplex (AS) is a nematode that may be encountered as a parasite in various kinds of seafood. Human beings may accidentally acquire AS larvae by eating raw or undercooked seafood. In addition to human parasitization (anisakiasis), this nematode can induce allergic reactions. AS-related diseases are frequent, especially in those countries with a high level of fish consumption and with traditions of eating raw or undercooked seafood. To our knowledge, this is the first report of gingivostomatitis secondary to the ingestion of fish with AS parasites.

12/31. Splenic anisakiasis resulting from a gastric perforation: an unusual occurrence.

    We report a case of gastric perforation by anisakis sp. with consequent localization of the larva in the spleen. An 86-year-old white woman was admitted to our surgical department with a diagnosis of acute abdomen. She had a history of abdominal pain, and her laboratory data showed leukocytosis. In the plain abdominal radiograph, pneumoperitoneum was evident; a computed tomography (CT) scan of the abdomen confirmed the presence of extraluminal air. Anamnesis disclosed the ingestion of raw fish during the week preceding her illness. The patient was underwent emergency laparotomy. A small gastric perforation and a nodular area at the superior pole of the spleen were found. Surgical treatment was performed successfully and consisted of excision of the gastric lesion and splenectomy. The histological diagnosis revealed the presence of gastritis with an ulcer, and in the splenic tissue, some necrotic foci containing cross-sectioned degenerated worms compatible with anisakis larva.

13/31. intussusception due to intestinal anisakiasis: a case report.

    This report describes our experience of intussusception due to intestinal anisakiasis which was treated by laparoscopy-assisted surgery. The unique sonographic findings of this complication were a pseudokidney sign and a target sign with an edema of Kerckring's folds in the intussusceptum. Surgeons should know about intussusception as a rare complication of intestinal anisakiasis. Sonography, computed tomography and laparoscopy are helpful in diagnosing and treating this complication.

14/31. CT findings of surgically verified acute invasive small bowel anisakiasis resulting in small bowel obstruction.

    Acute invasive small bowel anisakiasis is an extremely rare cause of small bowel obstruction. The authors report a case of surgically verified small bowel anisakiasis resulting in small bowel obstruction. A 54-year-old man presented with suddenly developed diffuse abdominal pain after ingestion of raw fish. The peripheral blood examination showed leukocytosis without eosinophilia. CT showed a long segment of thickened small bowel accompanied by a focal narrowed portion and combined with ascites. When these findings are noted in patients with a history of recent ingestion of raw or undercooked fish, the diagnosis of small bowel anisakiasis should be considered in order to avoid application of unnecessary surgical treatment, in spite of the severity of the abdominal pain and bowel obstruction.

15/31. anisakis infestation: a case of acute abdomen mimicking Crohn's disease and eosinophilic gastroenteritis.

    anisakiasis is a rare parasitic disease transmitted to humans by the ingestion of raw fish, which can initially present with acute abdomen. We report the case of a man, a habitual consumer of raw fish, who underwent surgery for acute abdomen, initially attributed to Crohn's disease and then later interpreted as eosinophilic enteritis. Only the subsequent careful histological examination of the surgical specimen, revealing full thickness eosinophilic infiltrate, generally typical of infestation, led to the detection of anisakis simplex larva. In cases of acute abdomen, in the presence of a positive history of raw fish ingestion, it is therefore reasonable to consider the possibility of anisakiasis.

16/31. Acute abdomen due to small bowel anisakiasis.

    The popularity in Western countries of dishes based on raw fish has led to an increased incidence of anisakiasis, a human parasitic disease caused by the ingestion of live anisakid larvae. The entire digestive tract may be involved, but the stomach and the small intestine are the most frequently affected sites. We report a case of acute abdomen due to anisakis simplex infection that caused small bowel obstruction.

17/31. Pulmonary anisakiasis presenting as eosinophilic pleural effusion.

    A 63-year-old man developed a pleural effusion with marked eosinophilia, which was more prominent in the pleural fluid than in the peripheral blood. The pleural effusion spontaneously disappeared 7 days after admission. A multiple dot enzyme-linked immunosorbent assay for anisakiasis was strongly positive for both the serum and pleural fluid. The serum IgG titre for anisakis simplex gradually decreased over 7 months. It is suspected that anisakis larvae can penetrate the alimentary canal, and then migrate into the pleural cavity through the diaphragm. Screening with a serological test is useful in the diagnosis of this condition; human pulmonary anisakiasis.

18/31. Intestinal anisakiasis in italy: a case treated by emergency surgery.

    anisakiasis is a fish-borne zoonotic disease. A case of intestinal anisakiasis in a woman who had consumed raw marinated anchovies was reported. The intestinal localization resulted in occlusive acute abdomen which required an emergency surgical treatment. The histological examination of the eosinophilic granuloma removed from the resected colon revealed the presence of larval nematodes of the genus anisakis as causative agents.

19/31. anisakis simplex-induced small bowel obstruction after fish ingestion: preliminary evidence for response to parenteral corticosteroids.

    BACKGROUND & AIMS: Gastrointestinal anisakiasis, a fish-borne zoonoses, may be acquired by humans after the ingestion of raw marine fish infested with larvae of the nematode anisakis simplex. Because of the invasive nature of the parasite, inflammatory obstruction or perforation of the gut wall may result. Although rare, anisakis-induced intestinal obstruction is becoming a growing public health problem in Mediterranean areas, such as spain, with a high fish-intake-based diet. Unawareness of this entity and nonspecific clinical symptoms, along with the lack of alternative therapeutic options other than conservative measures, may explain why half of these patients require abdominal laparotomy for diagnostic and therapeutic purposes. methods: We describe a series of 8 patients with acute intestinal anisakiasis treated in our center from July 2001 to January 2004. RESULTS: The first 3 patients underwent segmental ileal resection for imminent peritonitis. The remaining 5 patients were treated with intravenous 6-methylprednisolone (1 mg/kg/24 h) for 5 days with fast clinical and radiologic resolution in all 5 patients with no adverse reactions. CONCLUSIONS: Although preliminary, our data may suggest that parenteral corticosteroids could be a reasonable, inexpensive, and safe alternative in these patients to prevent intestinal resection.

20/31. Four cases of gastric submucosal mass suspected as anisakiasis.

    anisakiasis is a parasitic disease caused by ingestion of raw fish infected with anisakid larvae. Endoscopic changing patterns of submucosal lesions in chronic gastric anisakiasis have not been known yet. Here we report 4 cases of suspected gastric anisakiasis which were improved during follow-up periods without surgical treatment. The patients presented with abdominal pain, nausea and vomiting after consuming raw marine fish, and visited our gastroenterology outpatient department. Their endoscopic findings showed firm and yellowish submucosal masses accompanied with eccentric erosions. Histologic findings showed severe eosinophilic infiltrations. In blood tests, peripheral eosinophil counts and total IgE levels were elevated. We believed that all cases were caused by larval anisakid infections. The submucosal mass lesions disappeared during the follow-up periods of 2 to 4 mo.
