Yersinia enteritis may present with alarming gastrointestinal manifestations. The aim of this study was to review the cases of children admitted to a general hospital with a preliminary diagnosis of surgical nature and subsequently proven to be infected by Yersinia enterocolitica. All cases of children aged less than 14 years with stool cultures positive for Y. enterocolitica during the 12-year period January 1993 through December 2004 were analyzed. Y. enterocolitica was isolated from the stools of 71 children with gastrointestinal manifestations; 27 children were treated as outpatients and 44 were hospitalized. Six were admitted to the Pediatric Surgery Department (13.6% of the total hospitalizations and 8.4% of all Y. enterocolitica cases). Four of the Pediatric Surgery patients presented with abdominal pain and right lower quadrant tenderness. The preliminary diagnosis of appendicitis was excluded during hospitalization and none of them underwent appendectomy. The other two children were admitted for vomiting initially attributed to a preceding head injury and for diarrhea and a perianal abscess. Two children were given antibiotics and all had an excellent outcome. Y. enterocolitica enteritis manifestations can infrequently mimic appendicitis or other surgical conditions but should remain in the differential diagnosis of children presenting with an acute abdomen.
traumatic duodenal hematoma (DH) is an unusual event, occurring mainly in children and young individuals, with a male predominance in both age groups. Furthermore, it can be a diagnostic challenge because of unreliable history, nonspecific signs and symptoms, delayed appearance, and the duodenum's retroperitoneal location.
1,2Sonography is considered a reliable screening tool for blunt abdominal trauma (BAT) 3,4 ; however, since the beginning of the last decade, only a small number of reported DH cases 5-8 have been described by sonography. We illustrate the sonographic findings at the diagnosis and follow-up of a traumatic DH in a young man who was treated expectantly. We also present the sonographic findings of the resulted complete obstruction of the upper gastrointestinal (GI) tract and the DH's postoperative sonographic appearance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
