1/15. Yersinia enterocolitis mimicking Crohn's disease in a toddler.A 31/2-year-old girl presented with persistent abdominal pain, fever, vomiting, and diarrhea accompanied by rash, oral ulceration, anemia, and an elevated sedimentation rate. Initial evaluation revealed no pathogens and was extended to include abdominal ultrasound and computed tomography showing marked ileocecal edema and mesenteric adenopathy. colonoscopy revealed focal ulceration from rectum to cecum with histology of severe active colitis with mild chronic changes. Enteroclysis demonstrated a nodular, edematous terminal ileum. Because of the patient's clinical deterioration despite antibiotics, these features were construed consistent with Crohn's disease, and glucocorticoid therapy was begun. By the ninth hospital day, admission cultures grew yersinia enterocolitica, and trimethoprim/sulfamethoxazole was begun followed by prompt clinical improvement. The delay in diagnosis afforded an unusually comprehensive clinical description of the presentation and diagnosis of Yersinia enterocolitis in childhood.- - - - - - - - - - ranking = 1keywords = enterocolitis (Clic here for more details about this article) |
2/15. Recognition of yersinia enterocolitica multiple strain infection in twin infants using PCR-based dna fingerprinting.AIMS: yersinia enterocolitica causes several syndromes in humans. The most common presentation is enterocolitis in children, presenting as fever and diarrhoea. A Y. enterocolitica multiple strain infection in twin infants was investigated. methods AND RESULTS: One isolate was recovered from one patient and two morphologically-different isolates were recovered from the other infant. Biochemically, all isolates were identified as Y. enterocolitica group. The genomic DNA from each strain was purified and dna fingerprinting was performed. The banding patterns observed for Y. enterocolitica isolates 2 and 3, from patients 1 and 2, respectively, were identical when comparing the presence or absence of major bands. However, Y. enterocolitica isolate 1, from patient 1, showed a distinctive banding pattern from isolates 2 and 3. CONCLUSION: The findings indicate that one infant was colonized by more than one strain of Y. enterocolitica, demonstrating that multiple strains can colonize and invade a patient. SIGNIFICANCE AND IMPACT OF THE STUDY: Recognition of multiple strain infections can be important in diagnosis, treatment and prognosis of Y. enterocolitica infections, as well as in disease epidemiology. The technique described here offers a straightforward method for strain comparison.- - - - - - - - - - ranking = 0.2keywords = enterocolitis (Clic here for more details about this article) |
3/15. intussusception due to yersinia enterocolitica enterocolitis in a patient with beta-thalassemia.patients who are homozygous for thalassemia major are at risk for yersinia enterocolitica infections. We present a case of a 4-year-old child with intussusception of the terminal ileum whose past medical history was significant for beta-thalassemia. His monthly blood transfusions for this condition may have put him at risk for Y enterocolitica enterocolitis. The pathogenesis of this disease relates to the role of iron as an essential growth factor for Yersinia, and this patient's transfusions left him in an iron-overloaded state, despite treatment with Desferal. Our patient's unusual presentation of intussusception was secondary to the mass effect caused by lymphoid hyperplasia, specifically hypertrophied peyer's patches in the ileum caused by Y enterocolitica infection. To our knowledge, this is the first such case of intussusception caused by Yersinia to be reported.- - - - - - - - - - ranking = 1keywords = enterocolitis (Clic here for more details about this article) |
4/15. yersinia enterocolitica sepsis in an adolescent with Cooley's anemia.Human infections due to yersinia enterocolitica have been reported worldwide, predominantly in europe. However, there have been few reports of yersinia enterocolitica infection in taiwan. We report a case of Y. enterocolitica sepsis in a 15-year-old Taiwanese girl with Cooley's anemia and insulin-dependent diabetes mellitus. She presented at admission with fever, shock and consciousness disturbance. She had symptoms of abdominal pain, vomiting and diarrhea for three days before admission. blood pressure stabilized after intravenous normal saline rescue. Blood culture yielded Y. enterocolitica 2 days later and ceftriaxone was administered according to the results of sensitivity tests. She recovered well after a course of antibiotic treatment. Though Y. enterocolitica sepsis is rare in taiwan, clinicians should be aware of its tendency to develop in patients with Cooley's anemia, fever and enterocolitis and that its clinical course may include sepsis leading to shock.- - - - - - - - - - ranking = 0.2keywords = enterocolitis (Clic here for more details about this article) |
5/15. Spontaneous pleural empyema due to yersinia enterocolitica.yersinia enterocolitica is a well-known cause of enterocolitis. Although focal extraintestinal manifestations and disseminated disease have been described, usually in immunosuppressed patients, infection in the chest seems to be rare. We report the case of an alcoholic man who had spontaneous pleural empyema due to Y. enterocolitica.- - - - - - - - - - ranking = 0.2keywords = enterocolitis (Clic here for more details about this article) |
6/15. Unusual manifestations of yersinia enterocolitica infections diagnosed using novel methods.We report the cases of two patients who had infections due to yersinia enterocolitica. The first patient exhibited chronic recurrent fever, hepatic and splenic granulomas, and bone marrow abnormalities, and the second patient presented with enterocolitis with leukocytoclastic vasculitis of the skin. Cultures and agglutination titers were negative. Indirect immunofluorescence techniques with use of serotype-specific antisera and antisera to Yersinia outer-membrane proteins (Yops) were applied to biopsy specimens, and immunoblotting techniques for determining class-specific circulating antibodies to Yops were used for demonstrating these unusual manifestations of Y. enterocolitica infections.- - - - - - - - - - ranking = 0.2keywords = enterocolitis (Clic here for more details about this article) |
7/15. 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.- - - - - - - - - - ranking = 0.2keywords = enterocolitis (Clic here for more details about this article) |
8/15. intestinal obstruction complicating yersinia enterocolitica serotype O:21 infection in an infant.intestinal obstruction is an uncommon complication of yersinia enterocolitica infection. We report a case of enterocolitis in an 11-month-old infant, complicated by intestinal obstruction. Y. entercolitica serotype O:21, previously reported to cause severe disease, was isolated from the patient's stool. Unusual or complicated presentations of yersiniosis may be associated with more pathogenic strains of Y. enterocolitica.- - - - - - - - - - ranking = 0.2keywords = enterocolitis (Clic here for more details about this article) |
9/15. Flaccid quadriparesis associated with Yersinia enterocolitis-induced hypokalemia.A 23-year-old woman presented with diarrhea, flaccid quadriparesis, a low serum potassium level, and an elevated creatine kinase level. A stool culture yielded yersinia enterocolitica, and a muscle biopsy was compatible with a hypokalemic myopathy. The patient's diarrhea responded to sulfamethoxazole and trimethoprim therapy. We suggest that Y enterocolitica be added to the group of intestinal pathogens capable of producing hypokalemia and rhabdomyolysis.- - - - - - - - - - ranking = 0.8keywords = enterocolitis (Clic here for more details about this article) |
10/15. Yersinia enterocolitis in iron overload.Yersinia enterocolitis with peritonitis and septicaemia developed in a 4-year-old child with thalassemia intermedia and iron overload. It is likely that the illness was exacerbated by continued administration of desferrioxamine, a bacterial siderophore, which facilitated systemic spread of Yersinia. It is recommended that Yersinia enterocolitis be considered in children with iron overload and that desferrioxamine be discontinued and prophylactic antibiotics be administered while Yersinia is sought.- - - - - - - - - - ranking = 1.2keywords = enterocolitis (Clic here for more details about this article) |
