1/338. A case of cryptic miliary tuberculosis mimicking cholecystitis with sepsis.Miliary tuberculosis is a rare form of tuberculosis in industrialized countries. We report on a 69-year-old woman presenting a sepsis syndrome caused by cryptic miliary tuberculosis clinically mimicking a case of cholecystitis with sepsis. The patient died of a multi-organ failure on day 6 of her hospital stay.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
2/338. flavobacterium meningosepticum sepsis in an infant with a diarrheal prodrome.A full term, previously normal 2 1/2-month-old black boy was transferred to our hospital from an outlying facility on hospital day 5 for failure to thrive. Three weeks before transfer, the infant was hospitalized for a diarrheal illness with fever. The baby received 3 days of ceftriaxone empirically and was discharged home after the sepsis evaluation was negative. Mild diarrhea and steady weight loss continued and the baby was readmitted. Blood culture done on admission grew flavobacterium meningosepticum, an organism previously described as an uncommon cause of sepsis in neonates and immunocompromised individuals. As it is water-borne, it has been associated with infection via contaminated water. This organism is usually resistant to antibiotics commonly used for empiric treatment. To our knowledge, this is the first reported case of flavobacterium bacteremia associated with a prodromal and concurrent diarrheal illness.- - - - - - - - - - ranking = 2keywords = organ (Clic here for more details about this article) |
3/338. Central line sepsis in a child due to a previously unidentified mycobacterium.A rapidly growing mycobacterium similar to strains in the present mycobacterium fortuitum complex (M. fortuitum, M. peregrinum, and M. fortuitum third biovariant complex [sorbitol positive and sorbitol negative]) was isolated from a surgically placed central venous catheter tip and three cultures of blood from a 2-year-old child diagnosed with metastatic hepatoblastoma. The organism's unique phenotypic profile and ribotype patterns differed from those of the type and reference strains of the M. fortuitum complex and indicate that this organism may represent a new pathogenic taxon.- - - - - - - - - - ranking = 2keywords = organ (Clic here for more details about this article) |
4/338. ochrobactrum anthropi bacteremia.ochrobactrum anthropi (O. anthropi ), formerly known as achromobacter CDC group Vd, is a gram-negative bacillus that is aerobic, oxidase producing, and nonlactose fermenting. This organism has been found in environmental and hospital water sources and has pathogenic potential in humans. Most reports in the literature of O. anthropi bacteremia are associated with intravenous line infections. We describe a case of bacteremia with O. anthropi in a 33-month-old boy with acute osteomyelitis. O. anthropi bacteremia also has been reported in immunocompromised hosts. Rarely, O. anthropi has been a cause of soft tissue or bone infection.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
5/338. arcanobacterium haemolyticum and mycoplasma pneumoniae co-infection.Systemic infection caused by arcanobacterium haemolyticum is uncommon. We report a case of empyema and bacteraemia caused by this organism concomitant with mycoplasma pneumoniae infection.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
6/338. Rapid and definitive diagnosis of infectious diseases using peripheral blood smears.A timely diagnosis is essential in the management of septicemia and septic shock. Three patients are described, all of whom presented with fever and one of whom was hypotensive at the time of admission. In each patient, rapid diagnosis of the cause of fever was possible because microorganisms were identified on a peripheral blood smear obtained at the time of admission. This identification permitted prompt initiation of appropriate antimicrobial therapy. In addition, a literature review of use of peripheral blood smears in the diagnosis of bacterial, fungal, and parasitic infections is provided.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
7/338. Meropenem pharmacokinetics in a patient with multiorgan failure from Meningococcemia undergoing continuous venovenous hemodiafiltration.Meropenem is a carbapenem antibiotic with a broad antibacterial spectrum of activity. Its main route of elimination is through the kidneys, with 63% of the drug excreted unchanged in the urine. Meropenem clearance is diminished in renal impairment; therefore, doses need to be adjusted in patients with varying degrees of renal function. An appropriate dose of meropenem for patients undergoing continuous venovenous hemodiafiltration (CVVHDF) is unknown. We evaluated the pharmacokinetics of meropenem in a patient with fulminant meningococcemia undergoing CVVHDF. Meropenem concentrations in serial venous, arterial, and ultrafiltrate samples after a 1 g intravenous dose were measured using high-performance liquid chromatography (HPLC). Meropenem clearance was found to be 129.36 mL/min and 141.29 mL/min for every 8- and 12-hour dosing, respectively. Trough levels were above the MIC90 for neisseria meningitidis and most anaerobic pathogens. We recommend that meropenem 1 g intravenously every 12 hours be used as the initial dose in patients undergoing CVVHDF. Differences between meropenem clearance during CVVHDF and other forms of renal replacement therapy are discussed.- - - - - - - - - - ranking = 4keywords = organ (Clic here for more details about this article) |
8/338. Recurrent "Flexispira rappini" bacteremia in an adult patient undergoing hemodialysis: case report.A blood culture from a 65-year-old febrile man undergoing hemodialysis revealed, 5 days after inoculation, an unusual gram-negative fusiform rod with darting motility. During another episode of fever 21 days later, this campylobacter-like organism was again recovered from three blood cultures and subcultured under an H2-enriched microaerobic atmosphere. The organism was catalase negative and oxidase positive and hydrolyzed urea rapidly. sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis of whole-cell proteins was indistinguishable from that of "Flexispira rappini" LMG 8738 described by Archer et al. in 1988 (J. R. Archer, S. Romero, A. E. Ritchier, M. E. Hamacher, B. M. Steiner, J. H. Bryner, and R. F. Schell, J. Clin. Microbiol. 26:101-105, 1988). The analysis of the 16S ribosomal dna sequence revealed a similarity of 99.3% between the two strains. The patient recovered completely after a 4-week course of meropenem therapy. This is the first reported case of a recurrent "F. rappini" bacteremia in an adult patient, which confirms that this organism may be an invasive pathogen in immunocompromised patients, like other newly described helicobacter species.- - - - - - - - - - ranking = 3keywords = organ (Clic here for more details about this article) |
9/338. Septicemia caused by dysgonic fermenter 3 in a severely immunocompromised patient and isolation of the same microorganism from a stool specimen.Dysgonic fermenter 3 (DF-3)-associated bacteremia occurred in a febrile patient with acute myelocytic leukemia during aplasia. Another DF-3 isolate, identical by ribotyping, was grown 10 weeks later from stool collected in the absence of diarrhea. This is the first case in which DF-3 was isolated from blood and stool specimens from the same patient.- - - - - - - - - - ranking = 4keywords = organ (Clic here for more details about this article) |
10/338. serratia marcescens pseudobacteraemia in neonates associated with a contaminated blood glucose/lactate analyzer confirmed by molecular typing.Three episodes of serratia marcescens pseudobacteraemia occurred on a neonatal intensive care unit. Following the first two cases, one full term and one pre-term infant, the source was identified as a glucose/lactate analyzer. Blood culture and environmental isolates of the organisms involved were indistinguishable when subjected to pulsed-field gel electrophoresis of Spe 1 digests and PCR ribotyping. Failure to recognize pseudobacteraemia in neonates results in inappropriate therapy for the individual and increased antibiotic pressures on the unit. attention to the possibility of cross infection when using automated analyzers is required to minimize the risks of true or pseudoinfection to patients.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
