Acute ileitis in children is frequently diagnosed at the time of laparotomy for acute abdominal pain and is usually due to inflammatory bowel disease, Yersinia, or Campylobacter infections. We report a case in which a pathogenic strain of Escherichia coli was responsible for the disease. The diagnosis, microbiology, and epidemiology are discussed.

Human anisakiasis or anisakidosis is an unusual parasitation. During the autumn of 1996 seven patients came to our Hospital for such a condition. Five of these patients had the parasites in the gastroduodenal area (1 in the gastric body, 3 in the antrum and 1 in the duodenal bulb, this one with two parasites). Four out of the five patients consulted us for intense epigastric pain; only one developed a cutaneous rash. The fifth patient was diagnosed unexpectedly during an endoscopy appointment. Eosinophilia was detected in none. All the parasites were extracted endoscopically and identified as belonging to the Anisakis genera. Excepting for the patient with no complaint, the other four showed adhered larvas to mucosa. The two other patients were operated because of acute abdominal pain. At laparotomy an ileitis was seen and then resected. Under microscopic examination both ileon were found to be edematous and infiltrated by eosinophils. Anisakis larvae were observed in the submucosa of one of the removed intestines. The other patient was diagnosed after an immunologic study consisting of radioimmunoassay and Western Blot. Five of the seven patients (71%) acquired the parasites after consumption of anchovies with vinegar.

The purpose of our study is to emphasize the central role of ultrasound (US) in finding the cause of abdominal pain in children. Ultrasound of the lower abdomen quadrant should be considered in all cases in which the clinical signs and symptoms are not diagnostic of appendicitis. There is a wide range of clinical syndromes and diseases which can easily be diagnosed using a high resolution ultrasound with adjunct of color and power Doppler. The spectrum of abnormalities includes appendicitis, mesenteric lymphadenitis, infectious ileocecitis, Crohn's disease, intussusception, ovarian cysts, and encysted cerebrospinal fluid. One of the most common causes of acute abdominal pain in children is acute terminal ileitis (infectious ileocecitis) with mesenteric lymphadenitis. Ultrasound is the best tool to rapidly differentiate this disease from acute appendicitis, and prevent unnecessary laparotomy (Ref. 12).

Anisakidosis is the infestation of man by the larval stage of the parasite Anisakis simplex. A history of ingestion of raw or undercooked fish up to 48-72 hours before the onset is highly orientative. Based on the location of the lesions, various types of human anisakidosis have been identified: gastric, intestinal and luminal forms constitute the majority of cases and symptoms often mimic a variety of acute conditions such as gastritis, acute appendicitis, diverticulitis, or ileitis. We present a case of a young woman admitted to our department with acute abdominal pain. A history of raw fish ingestion was recorded. The patient was submitted to explorative laparoscopy in which an oedematous, thickened segment of ileum was observed. Therefore a small laparotomy was performed, followed by resection of the thickened ileum. The histological examination revealed transmural inflammation with marked infiltration of eosinophils. High levels of total IgE and Anisakis simplex-specific IgE were recorded. Anisakidosis is an underestimated cause of acute abdomen, and should be taken into consideration as a differential diagnosis in these conditions. Nevertheless, in most cases, the correct approach could prove difficult, because surgery may be necessary in these settings, allowing the diagnosis only by histological and parasitological investigation of the resected specimen.
