1/48. candida glabrata fungemia. Clinical features of 139 patients.Candida species are now the fourth leading cause of nosocomial bloodstream infection in hospitalized patients, and non-candida albicans species now surpass candida albicans. The clinical features of the most common non-candida albicans species, Candida (Torulopsis) glabrata, have not been well studied. We retrospectively reviewed the clinical features of 139 patients with C. glabrata blood-stream infection over a period of 7 years. The mean age of patients was 62 years, and the most common admitting diagnoses were malignancy (28%) and coronary artery disease (18%). The most common identified portals of entry were abdominal (22%) and intravascular catheters (16%). At the time of fungemia, 63% of patients had fever, 45% had change in mental status, and 30% were in septic shock. Three of 50 patients examined by an ophthalmologist had chorioretinitis. The overall hospital mortality was 49%. Factors associated with increased mortality in a regression model were prior abdominal surgery (odds ratio [OR] = 2.8; 95% confidence interval [CI] = 1.2-6.3, p = 0.01), and an elevated creatinine (OR = 2.2; 95% CI = 1.0-4.7, p = 0.05). When early deaths (< or = 72 hours) were censored, amphotericin b treatment and total dose were associated with reduced mortality (OR = 0.2; 95% CI = 0.1-0.4, p < 0.001). Nosocomial C. glabrata fungemia is not just a disease of debilitated and neutropenic patients, but affects a wide variety of patients and is associated with a high mortality.- - - - - - - - - - ranking = 1keywords = fever (Clic here for more details about this article) |
2/48. Unexpected Ebola virus in a tertiary setting: clinical and epidemiologic aspects.OBJECTIVES: To describe the clinical manifestations of viral hemorrhagic fever, and to increase clinicians' awareness and knowledge of these illnesses. DESIGN: Retrospective study of the clinical and laboratory data and management of two cases of Ebola virus infection with key epidemiologic data provided. SETTING: Two tertiary care hospitals. patients: Two adult patients, the index case and the source patient, both identified as having Ebola, one of whom originated in gabon. INTERVENTIONS: One patient was admitted to the intensive care unit. The other was managed in a general ward. MEASUREMENT AND MAIN RESULTS: Clinical and laboratory data are reported. One patient, a healthcare worker who contracted this illness in the course of her work, died of refractory thrombocytopenia and an intracerebral bleed. The source patient survived. Despite a long period during which the diagnosis was obscure, none of the other 300 contacts contracted the illness. CONCLUSIONS: Identification of high-risk patients and use of universal blood and body fluid precautions will considerably decrease the risk of nosocomial spread of viral hemorrhagic fevers.- - - - - - - - - - ranking = 2keywords = fever (Clic here for more details about this article) |
3/48. herpes simplex virus infection in a paediatric burn patient: case report and review.herpes simplex virus (HSV) infection in the burn patient is thought to occur relatively frequently. Most commonly, children with significant burns, particularly involving the head and neck, are affected. Burn related immunosuppression is thought to allow reactivation of latent HSV in most cases, although primary HSV infection has been recognized. Clinical manifestations vary from asymptomatic viral shedding, to prolonged fever with eruption of vesicles, to rare cases of systemic visceral dissemination. Healing partial thickness wounds and donor sites are most prone to infection. Laboratory confirmation of HSV infection relies on direct demonstration of the virus and/or observation of a rise in antibody titer. Treatment of an established HSV infection includes use of IV acyclovir, meticulous wound care, and efforts to prevent nosocomial spread. The vast majority of cases resolve without sequelae unless complicated by systemic, multiorgan HSV infection.- - - - - - - - - - ranking = 1keywords = fever (Clic here for more details about this article) |
4/48. Cluster of pulmonary infections caused by cunninghamella bertholletiae in immunocompromised patients.cunninghamella bertholletiae is a rare cause of pulmonary mucormycosis. We describe a cluster of invasive pulmonary infections caused by C. bertholletiae in 4 immunocompromised patients that occurred during a 2-year period at 1 center. Three of the patients were receiving antifungal prophylaxis with itraconazole. Presenting symptoms were fever unresponsive to antibacterial chemotherapy, hemoptysis, and infiltrates on chest radiograms. Three patients were treated with liposomal amphotericin b. Only 1 patient survived.- - - - - - - - - - ranking = 1keywords = fever (Clic here for more details about this article) |
5/48. Infected mediastinitis secondary to perforation of superior vena cava by a central venous catheter.We describe the first case of infected mediastinitis associated with central venous catheter insertion. The rare occurrence of this complication may be explained by the fact that it results from central venous catheter-related bloodstream infection and catheter perforation of superior vena cava. The symptoms of this complication (chest pain, dyspnoea) are not specific. Diagnosis should be confirmed by chest x-ray and computerized tomography which show hydromediastinum and pleural effusion. Removal and subsequent culture of the catheter tip will confirm infection. Appropriate antibiotic therapy, guided by sensitivities of the cultured organisms, should be commenced. Any pleural effusion should be drained by thoracocentesis, and the pleural fluid cultured. In case of fever, bacteraemia or shock, a thoracotomy to drain mediastinal and pleural effusions may be considered.- - - - - - - - - - ranking = 1keywords = fever (Clic here for more details about this article) |
6/48. Fulminant stenotrophomonas maltophilia soft tissue infection in immunocompromised patients: an outbreak transmitted via tap water.Soft tissue infection caused by stenotrophomonas maltophilia is uncommon, but nosocomial infections had been reported. We describe herein 2 young female patients, with severe neutropenia, on broad spectrum antimicrobial agents for neutropenic fever, with Hickman-type central venous catheter, who developed mucocutaneous and soft tissue infections with rapidly progressive and devastating course. Cultures from the skin of both patients and from blood of one of them grew S. maltophilia. Both patients died and post mortem examination of the patient with S. maltophilia bacteremia revealed extensive soft tissue necrosis and a vegetation on the mitral valve that grew S. maltophilia. The infection occurred in both patients at the same time and in the same ward. Epidemiological study was done, and surveillance cultures grew the organism from the faucets from the room of 1 patient and also from some of the neighboring rooms in our ward but not from any other ward nor in the water reservoir of the building.- - - - - - - - - - ranking = 1keywords = fever (Clic here for more details about this article) |
7/48. Patient-to-patient transmission of nosocomial malaria in italy.OBJECTIVE: To describe nosocomial transmission of malaria from patient to patient via blood exposure. patients: A 56-year-old man was admitted to an Italian hospital with fever and plasmodium falciparum parasitemia, but with no risk factors for malaria. Twenty days earlier, he had been admitted for bronchopulmonary disease to the hospital's intensive care unit, where a woman with P. falciparum malaria acquired abroad was present. methods: We reviewed both patients' medical records and searched for mosquitoes in the hospital and on the grounds. We interviewed the staff about patient care practices potentially involving contact with blood. The genetic identities of strains were determined by genotyping of the dna extracted from blood. RESULTS: Molecular genotyping showed that the two strains were identical. The only invasive procedures performed on both patients by the same staff on the same shift were capillary blood sampling by finger stick, intravenous drug administration, and substitution of total parenteral nutrition bags and intravenous sets. The fingerstick device used was designed to prevent person-to-person transmission of blood-borne infections, and the staff interviews did not reveal any incorrect use of aseptic techniques. The likely source of infection was identified during a training course 6 months later: a nurse reported that, when collecting blood, she placed patients' fingers directly on the blood glucose meter, a practice she had learned from a poster advertising the device. CONCLUSIONS: A nosocomial case of malaria was ascertained, which was likely due to patient-to-patient transmission via a contaminated blood glucose meter. Incomplete instructions for the meter seem to have played a role in this case.- - - - - - - - - - ranking = 1keywords = fever (Clic here for more details about this article) |
8/48. Emergence of resistance of vancomycin-resistant enterococcus faecium in a thermal injury patient treated with quinupristin-dalfopristin and cultured epithelial autografts for wound closure.vancomycin-resistant enterococcus faecium and faecalis (VRE) remains a major complication among critically ill patients. A 26-year-old patient with 65% total body surface area burns (TBSA) was infected with several E. faecium strains during his admission that were resistant to vancomycin. Because chloramphenicol was the standard treatment at this time, this drug was initiated until, the organism was identified as E. faecium and reported as susceptible to quinupristin-dalfopristin. Given these data, it was then decided to discontinue the chloramphenicol therapy. Quinupristin-dalfopristin therapy resulted in initial reduction of fever and white blood cell counts that continued over the next 5 days. However, on day 7 of quinupristin-dalfopristin therapy, a return of fever and elevation of the white blood cell count was noted and a repeated E. faecium blood culture demonstrated sudden resistance to quinupristin-dalfopristin (Bauer-Kirby zone size <14 mm). chloramphenicol was restarted and the patient improved slowly over a period of 16 days. Our indigenous VRE had limited exposure to quinupristin-dalfopristin in the recent past; however, resistance emerged with the first commercial use of this agent in our burn treatment center. High-dose chloramphenicol treatment did not appear to impair engraftment of cultured epithelial autografts (CEA) in this patient.- - - - - - - - - - ranking = 2keywords = fever (Clic here for more details about this article) |
9/48. pichia ohmeri fungemia associated with phlebitis: successful treatment with amphotericin b.We report a case of fungemia caused by the yeast-form fungus pichia ohmeriin a 59-year-old hospitalized patient. P. ohmeri was found in all of the patient's blood cultures collected on days 52, 57, 59, and 64 of his hospital stay. Intermittent fever developed on the 52nd hospital day and persisted for about 10 days. The patient had previously received intensive antimicrobial therapy for a ventriculoperitoneal shunt infection and subsequent nosocomial pneumonia. Although a central venous catheter was not used in the patient, he suffered from tender swelling of the right leg due to peripheral phlebitis at the site of insertion of a peripheral venous catheter (which had already been removed at the onset of fever), the same site from which P. ohmeri was isolated. The fungemia and phlebitis cleared following 14-day amphotericin b therapy. This case shows that P. ohmeri can be a nosocomial bloodstream pathogen associated with phlebitis.- - - - - - - - - - ranking = 2keywords = fever (Clic here for more details about this article) |
10/48. serratia marcescens bacteremia associated with schistosomiasis mansoni.The case of a 21-year-old man coming from rural Paraiba, northwestern brazil, with schistosomiasis mansoni associated with serratia marcescens bacteremia, is reported. His main complaints on admission were fever, diaphoresis and chills for ten days, and diarrhoea that lasted for four days. On physical examination he had jaundice and hepatosplenomegaly. Diagnosis of S. marcescens bacteremia was made by isolation of the bacterium in blood culture, and schistosomiasis was diagnosed by rectal and liver biopsies. This is the first time that the association of S. marcescens bacteremia and schistosomiasis mansoni is recognized. Although our case does not fit into the classic definition of prolonged bacteremia associated with schistosomiasis, it can be considered as a mild form of this association. With the improvement of medical assistance and laboratory facilities, early diagnosis of this association will be made more frequently, cases with short duration will be diagnosed few days after the start of the symptoms, and classic prolonged cases will become rarer.- - - - - - - - - - ranking = 1keywords = fever (Clic here for more details about this article) |
