In general, involvement of the upper gastrointestinal tract in Crohn's disease occurs concomitantly with involvement of the lower gastrointestinal tract. The diagnosis depends on clinical,endoscopic, histological and radiological evaluation. The presence of aphthoid ulcers, longitudinal ulcers, bamboo-joint-like appearance, stenoses and fistulas are endoscopic findings suggestive of the disease, and it is important to exclude the presence of Helicobacter pylori infection. The primary histological findings,which facilitate the diagnosis, are the presence of a chronic inflammatory process with a predominance of lymphoplasmacytic cells and active focal gastritis. The presence of epithelioid granuloma, although less frequent, is highly suggestive of the disease in the absence of chronic granulomatous disease. Treatment should include the use of proton pump inhibitors associated with corticosteroids,immunomodulators and biological therapy according to the severity of the disease.展开更多

We may distinguish a urinary form from Schistosomes haematobium and an intestinal-hepatosplenic form mainly from Schistosomes mansonicharacterized by nausea, meteorism, abdominal pain, bloody diarrhea,rectal tenesmus, and hepatosplenomegaly. These infections represent a major health issue in Africa,Asia, and South America, but recently S mansoni has increased its prevalence in other countries, such as Europe countries and USA, due to international travelers and immigrants, with several diagnostic and prevention problems. We report a case of a 24-yearold patient without HIV infection, originated from Ghana, admitted for an afebrile dysenteric syndrome.All microbiologic studies were negative and colonoscopy revealed macroscopic lesions suggestive of a bowel inflammatory chronic disease. Since symptoms became worse, a therapy with mesalazine (2 g/d) was started,depending on the results of a bowel biopsy, but without any resolution. The therapy was stopped after 2 wk when the following result was available: a diagnosis of"intestinal schistosomiasis" was done (two Schistosoma eggs were detected in the colonic mucosa) and this was confirmed by the detection of Schistosoma eggs in the feces. Therapy was therefore changed to praziquantel(40 mg/kg, single dose), a specific anti-parasitic agent,with complete recovery. Schistosomiasis shows some peculiar difficulties in terms of differential diagnosis from the bowel inflammatory chronic disease, as the two disorders may show similar colonoscopic patterns.Since this infection has recently increased its prevalence worldwide, it was considered in the differential diagnosis of our patient with gastrointestinal symptoms.展开更多
