1/61. enterocolitis with pathogenic Escherichia coli infection in renal transplant recipients: case reports.

    PURPOSE: We report three cases of enterocolitis associated with pathogenic Escherichia coli infection in renal transplant recipients. methods/RESULTS: patients presented with abdominal pain and diarrhea at 1, 3 and 7 years after living-related renal transplantation. Pathogens of enterocolitis were identified by stool culture as verotoxin-2-producing O157:H7 E. coli, non-verotoxin-producing E. coli 06 and 0125. All patients were basically treated with fluid replacement with additional fosfomycin administration in the patient with O157:H7 E. coli infection. Immunosuppressive drugs were kept at maintenance doses throughout the treatment. CONCLUSION: All patients recovered uneventfully within 10 days after the onset of enterocolitis without severe complications.

2/61. Vertebral osteomyelitis: a rare complication of transvaginal ultrasound-guided oocyte retrieval.

    OBJECTIVE: To present a case of vertebral osteomyelitis as a complication of transvaginal oocyte retrieval. DESIGN: Case report. SETTING: The IVF unit of a university-affiliated hospital. PATIENT(s): A 41-year-old woman who underwent IVF-ET treatment. INTERVENTION(s): Standard IVF-ET treatment cycles with the use of transvaginal ultrasound for oocyte retrieval and computed tomography-guided needle aspiration. MAIN OUTCOME MEASURE(s): Recovery of the patient, sequelae, and recurrence. RESULT(s): Vertebral osteomyelitis was diagnosed and treated with antibiotics. CONCLUSION(s): When severe low back pain occurs after ovum retrieval, vertebral osteomyelitis should be considered. early diagnosis requires a high index of suspicion.

3/61. Infected hepatic cyst in a patient with multiple hepatic cysts: report of a case diagnosed by change of ultrasonographic findings.

    liver cysts are commonly observed, but infection of a liver cyst is a rare complication. Although patients have clinical symptoms, such as a high-grade fever and abdominal pain, diagnosing an infected cyst by abdominal ultrasonography, computed tomography (CT) with contrast medium and magnetic resonance imagings (MRI) is not always easy. We experienced an unusual case who had only clinical symptoms, such as high-grade fever and a right quadrant abdominal pain, but no imaging findings when admitted. Careful observation using ultrasonography once a week revealed signs of an infected cyst containing echogenic fluid 32 days after admission. We performed percutaneous transhepatic cystic drainage. When a patient has liver cysts and complains of high-grade fever and abdominal pain, liver cysts should be considered as a focus of sepsis, and we recommend repeat use of ultrasonography or CT, even if no typical findings occur the first time.

4/61. Intestinal bleeding and occlusion associated with shiga toxin-producing Escherichia coli O127:H21.

    We report a case of a nine-year old boy with vomiting, abdominal pain and fever, who underwent surgery with a diagnosis of appendicitis in Mendoza and from whom a shiga toxin-producing Escherichia coli (STEC) O127:H21 strain was recovered. Forty-eight hours after surgery he presented bilious vomiting and two episodes of intestinal bleeding. Laboratory findings included: hematocrit, 35%; blood urea nitrogen, 0.22 g/L. The urinary output was normal. The following day physical examination showed an alert mildly hydrated child, without fever but with distended and painful abdomen. The patient was again submitted to surgery with a diagnosis of intestinal occlusion. Bleeding and multiple adhesions in jejunum and ileum were found. The patient still had tense and painful abdomen and presented two bowel movements with blood; hematocrit fell to 29% and blood urea nitrogen rose to 0.32 g/L. STEC O127:H21 eae(-)/Stx2/Stx2vh-b( )/E-Hly( ) was isolated from a stool sample. He was discharged after 10 days of hospitalization and no long-term complications such as HUS or TTP were observed. This is the first report, to our knowledge, on the isolation of E. coli O127:H21, carrying the virulence factors that characterize STEC strains, associated to an enterohemorrhagic colitis case. This serotype was previously characterized as a non-classic enteropathogenic E. coli (EPEC). STEC infections can mimic infectious or noninfectious pathologies. Therefore an important aspect of clinical management is making the diagnosis using different criteria thereby avoiding misdiagnoses which have occasionally led to invasive diagnostic and therapeutic procedures or the inappropriate use of antibiotics.

5/61. Escherichia coli chest-wall hemorrhagic cellulitis associated with central-line placement.

    cellulitis is a common clinical entity. Hemorrhagic cellulitis is distinctly unusual and is most frequent in compromised hosts. In normal or near normal hosts, hemorrhagic cellulitis may rarely complicate gram-negative sepsis. Usually, hemorrhagic cellulitis occurs below the waist. The differential diagnosis includes invasive streptococcal infection, mixed aerobic and anaerobic infection, gram-negative sepsis, and gross gangrene. We present the first-known case of Escherichia coli chest-wall hemorrhagic cellulitis associated with a central line in a patient with renal failure.

6/61. Fatal emphysematous pyelonephritis with gas in the spinal extradural space in a patient with diabetes.

    BACKGROUND: Emphysematous pyelonephritis (EP) is a rare but life-threatening condition of the upper urinary tract, characterized by the presence of gas in the renal parenchyma and perirenal space. The vast majority of patients with EP (90%) are known to have diabetes, with Escherichia coli being the most common causative pathogen. CASE REPORT: We present a case of fatal bilateral EP in a patient with diabetes, with an unusual radiological finding of gas around the spinal cord and in the psoas muscle, with renal parenchymal sparing. Our case serves as an important reminder of this life threatening entity in diabetic patients, which is not well recognized by clinicians because of its rarity.

7/61. Behcet's disease complicated by pylephlebitis and hepatic abscesses.

    A 22 year old man presented with fever, abdominal pain, weight loss and diarrhea. Past medical history revealed recurrent aseptic meningitis, uveitis, and erythema nodosum. Further inquiry unveiled a prominent history of oral aphthous ulcers; all features of Behcet's disease. Imaging revealed mesenteric arteritis and pylephlebitis, septic thrombophlebitis of the portal vein, a previously unrecognized complication of Behcet's disease, with multiple intrahepatic abscesses. Portal venography demonstrated an extensively diseased, expanded, and obstructed portal venous system. Blood cultures and portal vein aspirate yielded polymicrobial flora. Percutaneous intraportal thrombolytic therapy and mechanical thrombectomy were attempted to restore flow to the portal venous system. This distinctly rare manifestation of Behcet's disease, pylephlebitis, may result from ischemic injury and structural compromise of the bowel mucosa, resulting from underlying vasculitis.

8/61. psoas abscess associated with infected total hip arthroplasty.

    A 65-year-old man with a left uncemented total hip arthroplasty performed 11 years previously was admitted with a history of progressive low back pain, left hip pain, and sepsis that had begun 6 months earlier. On physical examination, a gross, fluctuant mass was palpated in the left thigh. A computed tomography (CT) scan revealed a 6.5 x 3 cm left retrofascial psoas abscess communicating with the hip joint. The patient underwent irrigation and debridement of the hip with removal of the components. The psoas abscess was drained through the iliopsoas bursa. A residual psoas abscess was drained percutaneously under CT guidance. Cultures isolated Escherichia coli, and the patient responded to 6 months of ciprofloxacin therapy. After 1 year, the patient had no evidence of infection. Pathways of infection spread, diagnosis, and treatment of a patient with this rare association are discussed with a review of the literature.

9/61. uropathogenic escherichia coli as agents of diverse non-urinary tract extraintestinal infections.

    Escherichia coli isolates from 3 consecutively encountered patients with serious, invasive, non-urinary tract extraintestinal infections (pneumonia, deep surgical wound infection, and vertebral osteomyelitis with associated epidural/psoas/iliacus abscesses) were characterized, using molecular methods, as to extended virulence genotype and phylogenetic background. All 3 isolates exhibited virulence genotypes and genomic profiles characteristic of specific familiar virulent clones of extraintestinal pathogenic E. coli (ExPEC), which traditionally have been regarded primarily as uropathogenic or as associated with meningitis. These included E. coli O1/O2:K1:H7, E. coli O18:K1:H7, and a recently described E. coli O11/O17/O77:K52:H18 clonal group (clonal group A). These findings demonstrate the extraintestinal pathogenic versatility of ExPEC clones, which supports the use of an inclusive designation for such strains and suggests the possibility of cross-syndrome protective interventions. They also provide novel evidence that multidrug-resistant epidemic clonal group A can cause extraintestinal infections other than uncomplicated urinary tract infections and can cause them in hosts other than young women.

10/61. psoas abscess: the spine as a primary source of infection.

    STUDY DESIGN: Case report, literature review, discussion. OBJECTIVES: To emphasize the role of the spine as primary source of infection for psoas abscess. SUMMARY OF BACKGROUND DATA: spine-associated psoas abscesses increase with more frequent invasive procedures of the spine and recurring tuberculosis in industrialized countries. Diagnosis is often delayed by misinterpretation as arthritis, joint infection, or urologic or abdominal disorders. methods: We present six cases of psoas abscesses associated with spinal infections that were treated in our hospital from January to December 2001. Diagnostic and treatment concepts are discussed. RESULTS: Our data emphasize the importance of the spine as primary source of infection and suggest an increase in the incidence of secondary psoas abscess. Treatment includes open surgical drainage and antibiotic therapy. In patients with high operative risk and uniloculated abscess, a CT-guided percutaneous abscess drainage can be sufficient. It is essential to combine abscess drainage with causative treatment of the primary infectious focus. Related to the spine, this includes treatment of spondylodiscitis or implant infection after spinal surgery. Usually, several operations are necessary to eradicate bone and soft-tissue infection and restore spinal stability. Continuous antibiotic therapy over a period of 2-3 weeks after normalization of infectious parameters is recommended. CONCLUSION: The spine as primary source of infection for secondary psoas abscess should always be included in differential diagnosis. Because the prognosis of psoas abscess can be improved by early diagnosis and prompt onset of therapy, it needs to be considered in patients with infection and back or hip pain or history of spinal surgery.
