1/26. Perfusionist-transmitted bacterial mediastinitis in a heart transplant recipient.We report the case of a 56-year-old man who developed bacterial mediastinitis with methicillin-resistant staphylococcus aureus after undergoing heart transplantation. He had a history of insulin-dependent diabetes mellitus and prior cardiac surgery. To find the source of nosocomial infection, we cultured nasal swab specimens from all hospital personnel involved in this operation. We used antibiotic sensitivity profiling and pulsed-field gel electrophoresis to subtype the involved microorganism. The S. aureus isolates from the patient and the perfusionist were identical to each other and were different from the strains previously found in our hospital. It is almost certain that the S. aureus mediastinitis in this patient was transmitted from the perfusionist. We recommend obtaining cultures from hospital staff members when there is an outbreak of staphylococcal infection.- - - - - - - - - - ranking = 1keywords = nosocomial infection, nosocomial (Clic here for more details about this article) |
2/26. Nosocomial submandibular infections with dipterous fly larvae.In September 1998, a case of nosocomial cutaneous myiasis caused by Lucilia sericata (Meigen, 1826) in a 77-year-old male was found. The patient had been receiving partial maxillectomy due to the presence of malignant tumor on premaxilla. This is the first verified case involving Lucilia sericata in Taegu, korea. In the present paper, the salient morphological features of the third instar larvae involved have been studied.- - - - - - - - - - ranking = 0.064504785629456keywords = nosocomial (Clic here for more details about this article) |
3/26. Polymicrobial ventriculitis and evaluation of an outbreak in a surgical intensive care unit due to inadequate sterilization.At the end of 1999, a case of polymicrobial ventriculitis in the Department of neurosurgery followed by an outbreak of serratia marcescens mediastinitis in the intensive care unit of cardiovascular surgery occurred. These nosocomial surgical infections were considered to be the result of contamination of surgical sites with inadequately sterilized instruments or theatre linen. An epidemiological survey was focused on the central sterilization unit of the hospital. The microbiological results of this survey proved that the cause of the outbreak was the use of inadequately decontaminated theatre linen. This study indicates that strict infection control measures including the control of sterilization procedures and a well-organized infection control team are necessary to prevent nosocomial surgical infections.- - - - - - - - - - ranking = 0.12900957125891keywords = nosocomial (Clic here for more details about this article) |
4/26. corneal ulcer of the side port after phacoemulsification induced by acinetobacter baumannii.A 75-year-old man had clear corneal phacoemulsification using a temporal approach in the left eye. Two months after surgery, a focal corneal epithelial defect developed with infiltration near the lower limbus on the site of the side-port incision. The culture of corneal scrapping grew acinetobacter baumannii, which is resistant to most ordinary antibiotics in sensitivity tests. After appropriate antibiotic treatment, the ulcer healed gradually with vessel ingrowth. acinetobacter baumannii is usually found in nosocomial infection of immune-compromised patients in the intensive care unit. It is a rare pathogen of infectious keratitis. Our case, with its unusual infection site, may point to potential risk factors for this pathogen.- - - - - - - - - - ranking = 1keywords = nosocomial infection, nosocomial (Clic here for more details about this article) |
5/26. surgical wound infection associated with Staphylococcus sciuri.We describe a case of surgical wound infection due to Staphylococcus sciuri. The isolated strain was susceptible to trimethoprim-sulfamethoxazole, erythromycin, chloramphenicol, ciprofloxacin and vancomycin and resistant to gentamicin, clindamycin, rifampicin, methicillin, ampicillin and ceftriaxone. The multiresistance of the strain had a serious impact on the prolonged course of the infection. Although this bacterium is principally found in animals, our strain was probably of nosocomial origin.- - - - - - - - - - ranking = 0.064504785629456keywords = nosocomial (Clic here for more details about this article) |
6/26. Postoperative pneumococcal cellulitis in systemic lupus erythematosus.This paper reports a case of nosocomial pneumococcal cellulitis that developed following a lymph-node biopsy in a woman being treated with high-dose intravenous corticosteroids for systemic lupus erythematosis (SLE). Her rapid and severe clinical deterioration was similar to that caused by group A streptococcus. The risk factors for the development of nosocomial pneumococcal cellulitis as a complication of SLE are reviewed and preventive measures discussed.- - - - - - - - - - ranking = 0.12900957125891keywords = nosocomial (Clic here for more details about this article) |
7/26. surgical wound infection by aspergillus fumigatus in liver transplant recipients.Cutaneous aspergillosis is generally associated with immunosuppression, burns, and major trauma. Most cases are acquired by direct inoculation, although cutaneous involvement does occasionally occur with disseminated disease. Surgical wound infections caused by Aspergillus species are very unusual and to our knowledge have not been described in the setting of organ transplantation. We describe two liver transplant recipients who developed wound aspergillosis during a nosocomial outbreak of Aspergillus infection. Infection developed in the second and fourth postoperative week respectively, and in both cases wound appearance mimicked necrotizing fasciitis. Both patients died despite local debridement and antifungal therapy with amphotericin b. Aspergillus must be added to the list of potential pathogens of surgical wounds, especially in the setting of organ transplantation.- - - - - - - - - - ranking = 0.064504785629456keywords = nosocomial (Clic here for more details about this article) |
8/26. enterocolitis due to methicillin-resistant staphylococcus aureus--report of two cases.Two cases of postoperative enterocolitis due to methicillin-resistant staphylococcus aureus (MRSA) after gastrectomy were experienced. Case 1: A 59-year-old male underwent subtotal gastrectomy for advanced gastric cancer. Diffuse peritonitis progressed after the first operation, so reoperation for drainage was required. Two days after the second operation, a profuse watery diarrhea developed. Case 2: A 46-year-old male underwent total gastrectomy for early gastric cancer. On the fourth postoperative day, frequent vomiting and cholera-like diarrhea started, followed by profound shock several hours later. Both cases were treated successfully by the administration of vancomycin. Stool cultures of both cases revealed MRSA and it had the same minimal inhibitory concentration, coagulase type and enterotoxin type, so that nosocomial infection was indicated.- - - - - - - - - - ranking = 1keywords = nosocomial infection, nosocomial (Clic here for more details about this article) |
9/26. Cell index--a new parameter for the early diagnosis of ventriculostomy (external ventricular drainage)-related ventriculitis in patients with intraventricular hemorrhage?Temporary intraventricular catheters for managing acute obstructive hydrocephalus caused by intraventricular haemorrhage carry a high risk of developing ventriculostomy-related ventriculitis (VRV). The aim of this prospective study was to validate a new parameter for the early detection of an intraventricular infection. methods: patients with external ventricular drainage due to intraventricular haemorrhage were enrolled in this prospective study. Leucocytes and erythrocytes in cerebrospinal fluid (CSF) and peripheral blood as well as bacteriological and chemical analysis of both were examined daily. The ratio of leucocytes to erythrocytes in CSF and leucocytes to erythrocytes in peripheral blood was calculated (so called cell index (CI)) and these values were compared with the "conventionally diagnosed" drain-associated ventriculitis. Furthermore, the CI values of the non-ventriculitis and ventriculitis group were compared using the t-test with adjustment for unequal variances (Welch test). RESULTS: Thirteen patients with an external ventricular drainage (EVD) expected to be in place for more than seven days were enrolled. Seven patients developed a bacteriologically proven VRV (time 0) within 12 days (mean 8.57). Diagnosis of VRV by CI was possible up to 3 days (mean 2.28) prior to conventional diagnosis. P values (Welch test) showed a significant difference on days -3 (P = 0.03), -2 (P = 0.03) and -1 (P = 0.012) - i.e. 3, 2 or 1 day, respectively, prior to the time point when the CSF culture grew staphylococci -, when compared with the mean cell indices of the controls, and a highly significant difference on time 0 (P < 0.001). CONCLUSION: The calculated CI allows the diagnosis of nosocomial VRV in patients with intraventricular haemorrhage at a very early point of time.- - - - - - - - - - ranking = 0.064504785629456keywords = nosocomial (Clic here for more details about this article) |
10/26. mycobacterium goodii infections associated with surgical implants at colorado hospital.From February to October 2003, mycobacterium goodii wound infections were identified among three patients who received surgical implants at a colorado hospital. This report summarizes the investigation of the first reported nosocomial outbreak of M. goodii. Increased awareness is needed about the potential for nontuberculous mycobacteria to cause postoperative wound infections.- - - - - - - - - - ranking = 0.064504785629456keywords = nosocomial (Clic here for more details about this article) |
