1/11. Asymptomatic gastroduodenal anisakiasis as the cause of anaphylaxis.

    A great number of parasites have been reported in fish, but only a few of them are capable of infecting human beings. anisakiasis or anisakidosis is caused by sea nematodes of the genus anisakis, with the main implicated species being anisakis simplex. infection with anisakis causes a wide spectrum of clinical manifestations, ranging from symptoms related to the upper and occasionally lower digestive tract to allergic manifestations, mainly urticaria and anaphylaxis. We report a case of asymptomatic gastroduodenal anisakiasis presenting as severe anaphylaxis.

2/11. What does anisakis simplex parasitism in gastro-allergic anisakiasis teach us about interpreting specific and total IgE values?

    BACKGROUND: gastro-allergic anisakiasis is a mostly transitory clinical entity caused by anisakis simplex (A. simplex) and can be suspected by history and confirmed by fiberoptic gastroscopy and specific IgE. OBJECTIVE: we report a case of gastro-allergic anisakiasis, in which the parasite induces a high specific and total IgE response, and want to follow the specific and total IgE values by a serologic follow up over 10 months. methods: an analysis of total IgE and specific IgE against. A. simplex was performed within 24 hours, after 1, 4, 6 and 10 months. At month 4 and month 10 specific IgE against ascaris lumbricoides and echinococcus granulosus was determined in order to value cross-reactivity. RESULTS: there is an important raise in specific IgE against anisakis simplex (up to 903 kU/l) after 6 months and total IgE (up to 15,258 kU/l) after one month. Cross-reactive specific IgE against ascaris lumbricoides and echinococcus granulosus can be detected. CONCLUSIONS: we consider a raise of total and specific IgE as a typical feature of helminth infestation and learn that specific and total IgE values are highly variable in the months following the allergic and parasite-specific reaction. The amount of specific IgE against other cross reactive parasites depends directly on the total IgE values.

3/11. A case of acute gastric anisakiasis provoking severe clinical problems by multiple infection.

    Acute gastric anisakiasis with multiple anisakid larvae infection is reported. A 68-year-old woman residing in Busan, korea, had epigastric pain with severe vomiting about 5 hours after eating raw anchovies. Four nematode larvae penetrating the gastric mucosae in the great curvature of the middle body and fundus were found and removed during gastro-endoscopic examination. Another one thread-like moving larva was found in the great curvature of upper body on the following day. On the basis of their morphology, the worms were identified as the 3rd stage larvae of anisakis simplex. This case is acute gastric anisakiasis provoking severe clinical problems by the multiple infection and the greatest number of anisakid larvae found in a patient in korea.

4/11. 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.

5/11. anisakiasis in hawaii: a radiological diagnosis.

    Human anisakiasis, an increasing medical problem in japan, was recently identified in 7 people in hawaii. We report an 8th case occurring in an individual who had consumed a large amount of raw squid sushi at a restaurant. The diagnosis of anisakiasis in this patient was made after the parasite was identified by X-ray. To our knowledge, radiographic demonstration of the anisakiasis parasite has not been reported in hawaii previously.

6/11. Gastric anisakiasis: report of a case with clinical, endoscopic, and histological findings.

    A case of gastric anisakiasis in a 45-yr-old Oriental woman who had eaten fresh, raw salmon is reported. This is the second case of gastric anisakiasis reported in the united states. The clinical course, endoscopic features, and histological findings are described. With the increased popularity of Japanese restaurants and sushi bars in the united states, the incidence of anisakiasis can be expected to increase. Clinicians and pathologists should be aware of this unusual parasitic infestation in this country.

7/11. Endoscopic management of acute gastric anisakiasis.

    Early endoscopy was performed in six cases of acute gastric anisakiasis. Immediately after detecting the larva of anisakis, the larval body was extracted together with its surrounding mucosa by a biopsy forceps. With the removal of the larva, severe colic pain subsided rapidly. Two cases in our series were identified as the stage IV larvae of the anisakis, type I. It was presumed that the stage III larva had exuviated in the human stomach. It is emphasized that endoscopic extraction of larva is the most effective procedure in dealing with acute gastric anisakiasis.

8/11. A human case of gastric anisakiasis by Pseudoterranova decipiens larva.

    A case of gastric anisakiasis due to the larva of Pseudoterranova decipiens was confirmed by gastroendoscopic examination in April 23, 1991. The patient, residing in Pusan, was a 42-year-old housewife, who complained of severe epigastric pain and recalled that the symptom suddenly attacked her about 6 hours after eating raw Sebastes inermis. In the gastroendoscopic examination performed about 9 hours after the onset of the symptom, a long whitish nematode larva penetrating the gastric mucosa in the greater curvature of mid-body was found and removed with a biopsy forcep. The nematode was 29. 73 x 0.94 mm in size, had an intestinal cecum reaching over mid-level of the ventriculus and was identified as the 4th stage larva of P. decipiens.

9/11. Noncardiac chest pain due to acute gastric anisakiasis.

    This paper described the first confirmed case of acute anginalike chest pain caused by gastric anisakiasis. A 55-year-old male, with a history of a sudden onset of chest pain and also a history of eating raw mackerel and tuna 9 hr prior to the onset of chest pain, was found upon endoscopy to have an imbedded parasite in the mucosal lining of his stomach. The chest pain disappeared after the endoscopic removal of larva. endoscopy is highly recommended at the earliest possible time for patients who are suspected to have acute gastric anisakiasis.

10/11. Severe chest pain due to gastric anisakiasis.

    We treated two cases of gastric anisakiasis presenting with severe chest pain. In both cases, there was a history of prior ingestion of raw saltwater fish. After endoscopic removal of larvae, the chest pain disappeared and never recurred. Other diseases causing chest pain were ruled out by symptoms, signs, blood tests, electrocardiography, chest radiograph, and ultrasonic examination of the heart and abdomen. Thus the chest pain was considered to be caused by gastric anisakiasis. Gastric anisakiasis should be included in the differential diagnosis of acute chest pain.
