1/17. A case of abdominal syndrome caused by the presence of a large number of anisakis larvae.

    A 58-year-old woman living in Shizuoka Prefecture, japan, complained of severe epigastric pain and nausea about 8 h after having eaten 'Sashimi'. A gastrocamera examination undertaken as a result of her clinical history of gastric anisakiasis indicated that a large number of worms had penetrated the posterior walls. Fifty-six larval nematodes were directly removed from the greater curvature of the stomach with a gastroendoscopic biopsy clipper, and were identified as the larvae of anisakis simplex.

2/17. 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.

3/17. A case of anisakiasis causing intestinal obstruction.

    A 31-year old salesman living in Seoul developed suddenly abdominal pain due to intestinal obstruction. Exploratory laparotomy exhibited segmental jejunal cellulitis caused by penetrating anisakis larva. The patient had eaten raw fish. The typical history of intestinal anisakiasis was presented with a short review of Korean patients of anisakiasis.

4/17. anisakiasis of the colon: report of two cases with emphasis on the diagnostic and therapeutic value of colonoscopy.

    anisakiasis of the colon is a rare entity as compared with gastric anisakiasis, and its diagnosis is very difficult. We present here two cases--a 42-year-old woman and a 30-year-old woman--of anisakiasis of the colon treated by colonoscopic removal of the worm without surgery. The importance of colonoscopy for the diagnosis and treatment of this disease is briefly discussed.

5/17. Intestinal anisakiasis. A case diagnosed by morphologic and immunologic methods.

    The diagnosis of the fourth reported case of intestinal anisakiasis in the united states was based on the morphologic characteristics of the worm in histologic sections of resected ileum. Detection of antibodies to the worm by a radioallergosorbent test (RAST), enzyme-linked immunosorbent assay (ELISA), and an immunofluorescent antibody assay (IFA) support the diagnosis. IgE antibodies in patient serum reacted specifically to larval anisakis antigens but not to larval ascaris antigens in the RAST. IgG and IgM antibodies to larval anisakis antigen could be detected by ELISA up to six months after infection. IFA findings demonstrated that patient serum recognized the excretory-secretory products produced by the worm and showed their presence in vivo. These products appear to originate from the excretory pore and dorsal esophageal gland of the larval parasite.

6/17. anisakiasis confirmed by radiography of the large intestine.

    As yet, there has been no report of acute anisakiasis of the large intestine diagnosed by radiographic demonstration of the larvae. We present such a case, in which roentgenologic examination revealed anisakis larvae in the ascending colon.

7/17. anisakiasis caused by herring in vinegar: a little known medical problem.

    Six cases of intestinal anisakiasis, or herring worm disease, diagnosed over a two year period in a Belgian gastroenterology unit are described. They presented mainly as intestinal obstructions and larvae of this marine nematode were found in the intestinal wall of two of the four patients who were operated on. In two other patients awareness of the diagnosis permitted conservative treatment and spontaneous healing. In five patients symptoms developed after they had eaten herring marinated in vinegar, a hitherto little known source of the herring worm disease.

8/17. anisakiasis.

    Larval forms of nematodes of the Anisakidae family (cod or herring worms) can cause disease in people who eat raw or undercooked seafood. These nematodes are widespread along the eastern and western coasts of the united states, and the larvae can be found in fresh fish sold in any grocery store. Luminal infestation causes few symptoms. Invasive anisakiasis may be acute or chronic and may involve the stomach or the small intestine.

9/17. 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.

10/17. Probable pulmonary anisakiasis accompanying pleural effusion.

    The first probable human case of pulmonary anisakiasis is reported. A 37-year-old Japanese person in california developed pleural effusion after consumption of raw salmon at a seafood restaurant in san francisco. A marked eosinophilia was noted in the blood and pleural exudate. The patient was tested for helminthic infections by intradermal, complement fixation, Ouchterlony, and immunoelectrophoresis tests using antigens of various worm species. A specific precipitin band was recognized only with anisakis (Type I larvae) antigen.
