11/38. osteomyelitis/septic arthritis caused by kingella kingae among day care attendees--minnesota, 2003.kingella kingae is a fastidious gram-negative coccobacillus that colonizes the respiratory and oropharyngeal tract in children. K. kingae occasionally causes invasive disease, primarily osteomyelitis/septic arthritis in young children, bacteremia in infants, and endocarditis in school-aged children and adults. Although diagnosis of this organism frequently is missed, invasive disease is uncommon. Only sporadic, non-epidemiologically linked cases have been reported previously. In October 2003, the minnesota Department of health (MDH) investigated a cluster of two confirmed cases and one probable case of osteomyelitis/septic arthritis caused by K. kingae among children aged 17-21 months attending the same toddler classroom in a day care center. All reported within the same week with onset of fever, preceding or concurrent upper respiratory illness (URI), and refusal to bear weight on the affected limb. This report summarizes these cases and describes the epidemiologic investigation of the day care center. The findings underscore the need for clinicians and laboratorians to consider K. kingae infection in young children with Gram stain--negative or culture-negative skeletal infections.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
12/38. kingella kingae intervertebral diskitis in an adult.kingella kingae rarely causes infection and is mainly associated with endocarditis and septic arthritis in adults. The organism is also capable of causing intervertebral diskitis in children, but thus far, no reports of this infection occurring in adults have been published. A case of diskitis due to K. kingae in an adult is reported for the first time, and the literature on this infection in children is reviewed.- - - - - - - - - - ranking = 1.5keywords = infection (Clic here for more details about this article) |
13/38. moraxella catarrhalis bacteremic pneumonia in adults: two cases and review of the literature.moraxella (formerly Branhamella) catarrhalis is a gram-negative coccus now recognized as one of the common pathogens in respiratory infections. Documented cases of bacteremic pneumonia due to this organism, however, have been a rarity. Two cases of moraxella catarrhalis bacteremic pneumonia in immunosuppressed adult patients are reported. The clinical characteristics of these patients together with those of the seven adult and the six pediatric patients reported to date in the literature, are analyzed. All patients had an underlying condition and most were male. The mean age was 64.9 years. No adult patient had skin lesion, although purpuric rash was frequent in children. The overall morality rate was only 13.3%, in spite of the underlying diseases. In three patients the pneumonia was nosocomial. The seasonal recovery of moraxella catarrhalis in respiratory infections is significantly increased during the late fall through early spring period. Because most strains are beta-lactamase positive, empiric use of penicillin, ampicillin or amoxicillin for this organism can no longer be recommended.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
14/38. peritonitis due to neisseria mucosa in an adolescent receiving peritoneal dialysis.neisseria mucosa is part of the normal nasopharyngeal flora and rarely pathogenic in humans. Reports of serious infections associated with this pathogen are very unusual. A 17-year-old boy with end-stage renal disease due to IgA nephropathy presented with acute, spontaneous, symptomatic peritoneal dialysis-associated peritonitis without reported break in sterility or PD catheter exit site infection. beta-lactamase-negative N. mucosa was isolated from the dialysate effluent. Intraperitoneal antibiotic treatment with cephalothin/gentamicin for 5 days and subsequent ceftriaxone led to complete resolution of the infection. This case demonstrates that "non-pathogenic" Neisseria species can cause clinically severe peritonitis with high intraperitoneal neutrophil counts, elevated c-reactive protein levels in the peritoneal effluent (in the presented case, 27,600/mul and 3.6 mg/l, respectively) and impaired peritoneal membrane transport function. To our knowledge, this is the first case of N. mucosa peritonitis complicating chronic peritoneal dialysis in an adolescent patient.- - - - - - - - - - ranking = 1.5keywords = infection (Clic here for more details about this article) |
15/38. kingella kingae septic arthritis with endocarditis in an adult.kingella kingae is part of the nonpathogenic flora normally found in the oral cavity and pharynx. Recent reports have established that K. kingae can cause invasive infections in pediatric patients. Few cases have been described in adults, however. We report a case of K. kingae arthritis of the knee followed by endocarditis in a 59-year-old woman. physicians and microbiologists should be alert to the possibility of K. kingae infection. K. kingae is easy to detect provided its specific culture requirements are taken into account. synovial fluid inoculation into blood culture vials considerably increases the likelihood of K. kingae recovery in patients with septic arthritis.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
16/38. First case report of neisseria lactamica causing cavitary lung disease in an adult organ transplant recipient.We describe a case of an adult organ recipient patient with a pulmonary cavitary lesion due to neisseria lactamica, a harmless commensal organism that rarely causes human infection. To our knowledge, this is the first report of pulmonary disease caused by this organism and the second case of N. lactamica infection in an adult patient.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
17/38. kingella kingae spondylodiscitis in a child.Most osteoarticular infections in children are due to staphylococcus aureus. In this case, the isolation of kingella kingae by image guided disc aspiration resulted in modification and optimization of treatment. We take a look at a case of spondylodiscitis in a young child and review some of the current literature with regards to kingella kingae infections.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
18/38. moraxella atlantae bacteraemia in a patient with systemic lupus erythematosis.We describe the first reported case of human infection caused by moraxella atlantae (formerly known as CDC group M-3) and its successful treatment with intravenous cefuroxime. The isolation and identification of this species, as well as the pathogenesis of the infection, are discussed. It is recommended that isolates of moraxella species be speciated so that the epidemiological characteristics and pathogenesis of the infections caused by the various species may be understood more completely.- - - - - - - - - - ranking = 1.5keywords = infection (Clic here for more details about this article) |
19/38. Branhamella catarrhalis colonization of exposed nylon sutures.A 63-year-old man who had uncomplicated cataract surgery four years previously complained of having redness, blurred vision, and photophobia in his right eye for one week. Examination revealed numerous exposed nylon sutures with peculiar leaf-like, white deposits surrounding them, associated with underlying conjunctival leukocytic infiltration. Smears of the adherent material showed gram-negative diplococci and cultures produced heavy growth of Branhamella catarrhalis. Removal of the offending sutures and fortified topical antibiotic therapy resolved the ocular inflammation. The unique form in which this infection presented is a reminder that ocular surgical patients deserve long-term follow-up for problems like exposed sutures.- - - - - - - - - - ranking = 0.5keywords = infection (Clic here for more details about this article) |
20/38. Septicaemia caused by a penicillin-resistant moraxella-like organism in a neutropenic patient.Invasive infections with moraxella and related species are unusual. In this report we describe a case of septicaemia in an immunocompromised patient caused by a moraxella-like organism. The organism was difficult to identify in the laboratory and was also unusual in that it was resistant to penicillin.- - - - - - - - - - ranking = 0.5keywords = infection (Clic here for more details about this article) |
