21/218. Multiple liver abscesses secondary to yersinia enterocolitica.

    A 37-year-old male, a poorly-controlled insulin-dependent diabetic patient, was admitted to our hospital with complaints of high fever and confusion. Laboratory data showed hyperglycemia, positive inflammatory reaction and liver dysfunction. blood culture demonstrated yersinia enterocolitica. Liver CT scan showed multiple low density areas. These data were consistent with a diagnosis of liver abscess secondary to yersinia enterocolitica. He died of disseminated intravascular coagulation; subsequent autopsy confirmed the clinical diagnosis. liver abscess secondary to yersinia enterocolitica with septicemia is rare, but has been reported in compromised hosts. In the mechanism of this disease, the alimentary tract has been suggested to be the port of entry in most cases. ( info)

22/218. Chronic intussusception associated with yersinia enterocolitica mesenteric adenitis.

    An unusual case of chronic intussusception, without any digestive sign, secondary to mesenteric lymphadenitis caused by yersinia enterocolitica is reported. Operative reduction by taxis was performed but ileopexy and antibiotic treatment were also carried out to reduce chances of recurrent intussusception. ( info)

23/218. A palpable right lower abdominal mass due to Yersinia mesenteric lymphadenitis.

    Infection by yersinia pseudotuberculosis has become of increasing pathological importance. This report describes the case of a 12-year-old female with mesenteric lymphadenitis due to yersinia pseudotuberculosis. The patient presented with fever, abdominal pain, and a palpable right abdominal mass. Abdominal ultrasonic imaging and computerized axial tomography (CT) revealed a mass. An exploratory laparotomy was performed, followed by appendectomy and mesenteric lymph node biopsy. The diagnosis of Yersinia infection was confirmed by serology and bacterial culture of the biopsy material. This condition should be considered in patients with a right lower abdominal mass and symptoms similar to those of appendicitis. ( info)

24/218. yersinia enterocolitica endocarditis on a prosthetic valve.

    Yersinia entercolitica endocarditis has rarely been described before. This is the first report of prosthetic valve Yersinia enterocolitis endocarditis, complicated by infected brain embolization. The patient, however, completely recovered after 6 weeks of combined therapy with ceftriaxone and gentamicin. ( info)

25/218. Kikuchi's lymphadenitis: report of a yersinia enterocolitica-associated case and an overview of aetiology and clinical outcome.

    Kikuchi's lymphadenitis (KL; histiocytic necrotizing lymphadenitis without granulocytic infiltration) is a generally benign, febrile disorder of unknown aetiology with distinct histological features. To date, a minority of cases reported have been associated with infectious agents. A typical pathological case of KL is described where involvement of yersinia enterocolitica was shown by an indirect immunofluorescent assay applied to lymphatic tissue. The case is discussed with emphasis on recent insight into the course and aetiology of KL. ( info)

26/218. Yersinia infection mimicking recurrence of gastrointestinal stromal tumor.

    gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. So far, surgical resection has been the only curative treatment, but new options became available with the application of imatinib (Glivec) as a specific molecular inhibitor. Even after complete resection, GISTs have a high rate of recurrence and disease-linked mortality. Here we report on the case of a clinically well 57-year-old woman who presented to us 3 years after resection of a GIST of the small intestine. Abdominal ultrasound and CT scan showed intestinal wall thickening in the area of anastomosis and mesenteric lymphadenopathy, suggesting a recurrence of the primary GIST. However, serological testing was positive for yersinia antibodies. Surgical exploration revealed an asymptomatic infection with yersinia enterocolitica serotype O9, proven by positive culture and histology, which showed no evidence of malignancy. Prognostic variables for GIST as well as diagnostic measures and limitations for yersiniosis are discussed. In the end, only surgical exploration and histological analysis could establish the final diagnosis. In conclusion, GISTs have a high likelihood of recurrence even after complete resection, but an asymptomatic infection such as yersiniosis must be considered as a differential diagnosis to GIST recurrence.

27/218. yersinia infections in patients with homozygous beta-thalassemia associated with iron overload and its treatment.

    patients with homozygous beta-thalassemia are at increased risk of serious infections. yersinia enterocolitica is an organism with a predilection for these and other iron-overloaded patients. Three young adult patients with beta-thalassemia who were chronically transfused and developed yersiniosis are reported. iron overload and desferrioxamine use are predisposing factors, as supported by clinical, animal, and in vitro data. Iron excess both immunologically compromises the host and greatly enhances yersinial growth. Desferrioxamine may make host iron even more bioavailable to Yersinia. Recognition of this association and unusual manifestations in these patients such as an appendicitis-like syndrome may direct clinicians to earlier antiyersinial therapy and temporary cessation of chelation.

28/218. yersinia enterocolitica intestinal infection with ileum perforation: report of a clinical observation.

    yersinia enterocolitica infection is responsible in human beings for ileocolitis appearing with abdominal pain, diarrhoea and fever. This kind of disease usually heals spontaneously with no remarkable complication. intestinal perforation is a rare complication of the disease. To date only eleven cases of surgical complications arising from abscess and intestinal perforation due to yersinia enterocolitica have been reported in literature. In our clinical case the patient, who had previously undergone appendicectomy, required urgent surgery for pelvi-peritonitis due to intestinal perforation on necrotic-ulcerative ileitis with adenomesenteritis from yersinia enterocolitica. The surgical treatment combined with intestinal resection and targeted antibiotic therapy have proved to be effective. ( info)

29/218. Clinical and microbiologic characteristics of cutaneous infection with yersinia enterocolitica.

    The clinical and microbiologic features of primary cutaneous infections by yersinia enterocolitica are described in three children. Vesiculobullous lesions developed in two patients, and an intense granulation response followed incision and drainage. In the third child, cellulitis and abscess formation developed at the site of minor skin trauma. Y. enterocolitica isolates from the patients were extensively serologically, biochemically, and molecularly analyzed and compared with virulent Y. enterocolitica strains. The ability of the isolates to adhere to and invade eukaryotic cells was determined using in vitro assays; virulence was assessed by inoculation of suckling mice. The resulting data suggest that primary cutaneous infections by Y. enterocolitica involve strains that are as virulent as pathogenic gastrointestinal isolates. ( info)

30/218. Septicemia due to yersinia enterocolitica in a hemodialyzed, iron-depleted patient receiving omeprazole and oral iron supplementation.

    Septicemia occurred in a long-term hemodialysis patient on oral iron supplementation who had been treated for esophageal ulcer by omeprazole, an ulcer-healing drug. yersinia enterocolitica serotype 0:3 was recovered from blood cultures. A raised intraintestinal pH and an increased intraluminal iron load may have been contributing factors for the enhanced proliferation and generalized infection of Y enterocolitica. ( info)
