Prevalence of surgical site infections before and after the implementation of a multimodal infection control programme

2012

Objectives: In order to assess the prevalence of surgical site infections (SSIs) before and after the implementation of a multimodal infection control programme including the realization of a campaign to increase compliance with guidelines for antimicrobial prophylaxis, we designed and conducted the present study involving all 20 of the surgical departments of a large teaching hospital in Catania, Italy. Patients and methods: SSI definitions of the Hospital in Europe Link for Infection Control through Surveillance (HELICS) protocol were used in four 1 day point-prevalence surveys. After the first survey, an infection control programme was implemented involving the active commitment of surge…

Presentation and outcome of infective endocarditis in Spain: a retrospective study

2007

Summary Objective To analyze cases of infective endocarditis in patients who attended the Hospital General de Castellon, Spain, between 1999 and 2004. Methods This was a retrospective study. Demographic and clinical characteristics were assessed, variation in presentation over time was analyzed, and factors influencing outcome were determined. Results A total of 54 cases in 48 patients were included; 33 (61%) were in men. The median patient age was 62 years. Infective endocarditis occurred on a native valve in 36 cases (67%), a mechanical prosthetic valve in 12 (22%), and a pacemaker in six (11%). The mitral valve was the most commonly affected site. Transthoracic and/or transesophageal ech…

Mycobacterial Infection: A Difficult and Late Diagnosis in Stem Cell Transplant Recipients

2004

The Infectious Diseases Working Party of the European Blood and Marrow Transplant Group conducted a survey to obtain information about the frequency, presentation, and treatment of mycobacterial infection (MBI) in stem cell transplant (SCT) recipients. Among 29 centers, MBI was diagnosed in 0.79% of 1513 allogeneic and 0.23% of 3012 autologous SCT recipients during 1994-1998 a median of 160 days after transplantation. The mean interval between first symptoms and diagnosis was 29 days and was still longer for patients with atypical MBI or recipients of corticosteroid therapy. The prevalence of MBI was highest among those who received matched unrelated or mismatched STCs from related donors. …

What are the risk factors for postoperative infections of third molar extraction surgery: A retrospective clinical study-?

2018

Background This study aimed to identify (1) the predilection site of postoperative infection after third molar extraction surgery, (2) risk factors associated with postoperative infection, and (3) the cause of the difference between delayed- and early-onset infections. Material and Methods This retrospective study included 1010 patients (396 male, 614 female) who had ≥1 third molars extracted (2407; 812 maxilla, 1595 mandible). The risk factors were classified as attributes, general health, anatomic, and operative. Outcome variables were delayed- and early-onset infections. Results Postoperative infection was completely absent in the maxilla, and all infections occurred in the mandible, wit…

Fatal sepsis due to mycobacterium tuberculosis after allogeneic bone marrow transplantation.

2001

Mycobacterium tuberculosis is a serious, but rare infectious complication after allogeneic bone marrow transplantation. We describe a case of fatal sepsis due to Mycobacterium tuberculosis after allogeneic bone marrow transplantation for Philadelphia chromosome-positive ALL. The diagnosis was made after BAL. Although broad-spectrum antituberculous therapy was started immediately after diagnosis, blood cultures became positive for Mycobacterium tuberculosis. The patient developed severe pyrexias and finally died of multi-organ failure. Rapid progression of mycobacterial infection should be considered in patients post BMT with unexplained fever, particularly in patients from endemic areas.

Once-Daily Oral Levofloxacin Monotherapy versus Piperacillin/Tazobactam Three Times a Day: A Randomized Controlled Multicenter Trial in Patients with…

2004

A prospective, randomized, controlled multicenter trial was performed to evaluate the efficacy and safety of once-daily oral monotherapy with 500 mg levofloxacin in comparison with 4.5 g piperacillin/tazobactam 3 times a day in patients with low-risk febrile neutropenia. Low risk was defined by oral temperatureor = 38.5 degrees C on one occasion oror = 38.0 degrees C twice within 24 hours and granulocytopeniaor = 500/microL for less than 10 days. The primary end point was defined as defervescence after 72 hours followed by at least 7 afebrile days. Secondary end points were overall response, time to defervescence, survival on day 30, and toxicity. Thirty-four episodes were included. Fever o…

Phenotypic and genetic analysis of biofilm formation by Staphylococcus epidermidis.

2012

Objective. The most important virulence factor of Staphylococcus epidermidis is their capability to form a biofilm on the surfaces of implanted medical devices. The accumulative phase of biofilm formation is linked to the production of intercellular adhesin encoded by the icaADBC operon and accumulation-associated protein by the aap gene. The aim of the study was to investigate biofilm formation phenotypically and genetically in clinical strains of S. epidermidis in comparison with commensal strains. Material and Methods. The study was carried out in 4 hospitals in Riga, Latvia. In total, 105 clinical strains of Staphylococcus epidermidis isolated from patients’ blood (n=67) and intravenous…

Knowledge and attitudes towards the use of antibiotics in the paediatric age group: a multicenter survey in Italy

2017

Background : The misuse of antibiotics is one of the leading causes of antibiotic resistance. Paediatric patients are highly involved in this issue, as they are those who receive the largest amount of prescriptions of these drugs. Therefore, this study aimed to investigate the general knowledge regarding the use of antibiotics, as well as the attitudes related to the administration of these drugs to children, amongst parents of children in the paediatric age-group. Methods : In 2014, a multicentre cross-sectional study was conducted amongst parents of children aged 0–14. A questionnaire made up of 33 items was administered in waiting rooms of outpatient departments. Multivariable logistic r…

Microvascular injury and repair in acute human bacterial pyelonephritis.

1987

Acute inflammatory cell-capillary endothelial cell interactions, related to injury and repair, were investigated light and electron microscopically in acute human bacterial pyelonephritis. In inflammatory infiltrate-adjacent microvessels, the small capillaries were completely occluded by leukocyte plugs and the large capillaries were densely filled with acute inflammatory cells adhering to the endothelium. Severe damage to small and large capillaries was observed around endothelium adherent, degranulated neutrophil granulocytes containing phagocytosed bacteria. There were spaces in the endothelium, degradation of the vascular basement membrane, of the perivascular interstitial matrix and of…
