1/22. Acute intestinal anisakiasis in spain: a fourth-stage anisakis simplex larva.A case of acute intestinal anisakiasis has been reported; a nematode larva being found in the submucosa of the ileum of a woman in Jaen (spain). The source of infection was the ingestion of raw Engraulis encrasicholus. On the basis of its morphology, the worm has been identified as a fourth-stage larva of anisakis simplex. In spain, this is the ninth report of human anisakiasis and also probably the first case of anisakiasis caused by a fourth-stage larva of A. simplex.- - - - - - - - - - ranking = 1keywords = pain (Clic here for more details about this article) |
2/22. Eosinophilic gastritis due to anisakis: a case report.BACKGROUND: the parasite anisakis simplex is a helminth included in the nematode class. When man eats raw or rare fish and cephalopods infested by anisakis larvae, he can acquire the parasitic disease (anisakidosis). The parasite can also originate manifestations of immediate IgE mediated hypersensitivity in patients with sensitisation to it. methods AND RESULTS: we present the case of a 14 year old boy diagnosed of eosinophilic gastritis after endoscopic examination and biopsy associated to recurrent abdominal pain. After allergologic study, a type I hypersensitivity mechanism against anisakis simplex is confirmed by means of prick test, antigen specific IgE determination and antigen specific histamine release test. Sensitisation against fish proteins is ruled out as well as parasitic infestation. CONCLUSIONS: in this case report we demonstrate a type I hypersensitivity mechanism against anisakis simplex in a patient diagnosed of eosinophilic gastritis. This can be suspected in cases of gastritis or non filiated enteritis with a torpid evolution following the conventional treatment and especially if the onset of the symptoms is related with the intake of fish. The therapeutic success was reached when fish and shellfish were taken out of the diet. After two years without seafood ingestion our patient is asymptomatic and the allergologic study has been normalised.- - - - - - - - - - ranking = 0.16666666666667keywords = pain (Clic here for more details about this article) |
3/22. Gastrointestinal infection due to anisakis simplex in southern italy.The authors present four cases of infection due to anisakis in an area where people are prone to infectious diseases transmitted by raw fish, but in which the presence of this parasite has never been reported. Three of four cases were discovered accidently during surgical procedures for co-existing abdominal pathologies. Raw fish was apparently not involved in all patients. Characteristics of the patients are discussed.- - - - - - - - - - ranking = 0.0068983054970804keywords = area (Clic here for more details about this article) |
4/22. Gastroallergic anisakiasis: findings in 22 patients.BACKGROUND AND AIMS: Ingestion of Anisakidae larvae in raw seafood may cause anisakiasis. However, despite the high level of consumption of seafood in spain, only a few cases of anisakiasis have been reported until now. anisakis simplex can cause allergic reactions in sensitized patients as a result of its parasitism in the gastrointestinal tract. The purpose of this study was to analyse the clinical findings in 22 patients with gastroallergic anisakiasis. methods: patients with allergic and/or gastric symptoms after seafood ingestion were evaluated in the emergency room of the La Paz General University Hospital. skin testing for anisakis simplex and tests on the implicated seafood were performed and amounts of serum-specific immunoglobulin e were assessed. A gastroscopy was performed in those patients with severe allergic or/and persistent gastric symptoms after ingestion of raw or undercooked seafood. RESULTS: Twenty-two patients were diagnosed with gastroallergic anisakiasis in 1 year. Most patients presented to the emergency room of our hospital with allergic symptoms. Gastric symptoms were usually moderate. gastroscopy revealed local mucosal oedema and gastric erosion at the point of fixation. Two or more worms were detected in three patients. The mean time of latency of allergic symptoms was 5 h, while the mean time for gastric symptoms was 3 h. CONCLUSION: anisakis simplex parasitism was the causative agent of allergic and gastric symptoms. Gastroallergic anisakiasis appears to be a relatively common disease, that may have been underdiagnosed.- - - - - - - - - - ranking = 0.16666666666667keywords = pain (Clic here for more details about this article) |
5/22. A human case of gastric infection by Pseudoterranova decipiens larva.We report a case of gastric pseudoterranoviasis proven by gastrofiberscopy on Dec. 13, 1994. The 34-year-old male patient, residing in Chungju-shi, was admitted to Konkuk University Hospital complaining of prickling epigastric pain. The symptoms suddenly attacked him two days after eating raw marine fish at Chonan-shi. By the gastrofiberscopic examination, a long white-yellowish nematode was found from the fundus region of stomach. The worm was 34.50 x 0.84 mm in size, and was identified as a 3rd stage larva of Pseudoterranova decipiens judging from the position of the intestinal cecum. This is the 12th confirmed case of human pseudoterranoviasis in korea.- - - - - - - - - - ranking = 0.16666666666667keywords = pain (Clic here for more details about this article) |
6/22. Human infection by Pseudoterranova decipiens (nematoda, Anisakidae) in chile: report of seven cases.From 1997 to 1999, we identified seven human cases of infection by fourth stage larvae of Pseudoterranova decipiens in chile. All identified larvae were coughed up by the patients. Subjects were 10-55 years old; five were female. Some patients complained of coughing, expectoration, pharyngeal pain, nausea or anal and nasal pruritus. Larvae of three patients were coughed up from 36 h to 7 days after having eaten raw (cebiche or sushi) or lightly fried fish. P. decipiens has a marine life cycle. Infective third stage larva develop to adult stage in pinniped mammals. The nematode eggs are voided with the host faeces and develop and hatch releasing third stage larvae. Some crustaceans and fish act as hosts of third stage larvae. Man is an accidental host for third or fourth stage larvae.- - - - - - - - - - ranking = 0.16666666666667keywords = pain (Clic here for more details about this article) |
7/22. Small bowel obstruction caused by anisakiasis of the small intestine: report of a case.Enteric anisakiasis is a relatively rare disease that is difficult to diagnose preoperatively. We report a case of small bowel obstruction caused by enteric anisakiasis in a 59-year-old Japanese man who presented with abdominal pain a few hours after eating sliced, raw fish. Because of signs of an intestinal obstruction, a laparotomy was performed. Focal thickening and stenosis of the ileocecal region were seen about 100 cm from the end of the ileum and the lesion was excised. We found a moving anisakis thrusting its head into the mucosa of the excised small intestine. Histopathological examination revealed the infiltration of eosinophils in all layers of the intestinal wall and severe edema. Enteric anisakiasis is very rare, and its diagnosis is usually only made after laparotomy. Nevertheless, when signs of acute abdomen develop after the ingestion of raw fish, such as sushi or sashimi, the possibility of enteric anisakiasis should be borne in mind.- - - - - - - - - - ranking = 0.16666666666667keywords = pain (Clic here for more details about this article) |
8/22. anisakiasis of the colon presenting as bowel obstruction.anisakiasis is a disease caused by human infection by the anisakis larvae, a marine nematode found in raw or undercooked fish. With the increased popularity of eating sushi and raw fish (sashimi) in the united states infection with anisakis is expected to rise. We present the first reported case in the united states of intestinal anisakiasis presenting as a bowel obstruction. A 25-year-old healthy woman with no prior history of surgery presented to the emergency room with bowel obstruction by history and CT. CT also showed a mass in the right lower quadrant. She had eaten seviche, a raw fish appetizer, 2 days earlier and sashimi 3 weeks before admission. She was taken to the operating room for an exploratory laparotomy and was found to have an obstruction, the 2-cm mass in the mesentery, and diffuse mesenteric adenopathy. She had an ileocolectomy. pathology showed a degenerating fish worm, anisakiasis. She also had a serologic test for immunoglobulin e specific to anisakiasis and it was highly positive. Human infections, as mentioned before, are principally the result of ingestion of the anisakis larvae. These larvae are usually found in herring, mackerel, salmon, cod, halibut, rockfish, sardine, and squid. Most human infections have been reported from japan and The netherlands and involve the stomach. Invasion of the gastric or intestinal wall one to 5 days after eating raw fish may be characterized by the abrupt onset of abdominal pain, nausea and/or vomiting, diarrhea, or an ileus. For transient anisakiasis, supportive measures and reassurance are all that is needed. If the larvae have invaded the intestine or the stomach wall diagnosis and cure occur with endoscopic or surgical removal if evidence of obstruction or perforation is found. The incidence of anisakiasis in the united states is unknown but will likely continue to increase with the popularity of eating sashimi. This case is meant to demonstrate another possible cause for bowel obstruction in the patient who has just eaten raw or undercooked fish.- - - - - - - - - - ranking = 0.16666666666667keywords = pain (Clic here for more details about this article) |
9/22. 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.- - - - - - - - - - ranking = 0.16666666666667keywords = pain (Clic here for more details about this article) |
10/22. 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.- - - - - - - - - - ranking = 0.17356497216375keywords = pain, area (Clic here for more details about this article) |
