BACKGROUND As a novel biomarker of inflammation, procalcitonin (PCT) has proven useful to guide antibiotic therapy in intensive care unit (ICU). However, there are controversial on mortality. The aim of this study was to evaluate the utility of PCT-guided antibiotic therapy in critically ill adults and determine whether studies are sufficient. METHODS A systematic search in PubMed, Embase and...

background: biofilm infections are a major challenge in medical practice. bacteria that live in a biofilm phenotype are more resistant to both antimicrobial therapy and host immune responses compared to their planktonic counterparts. so, there is need for new therapeutic strategies to combat these infections. a promising approach [known as photodynamic inactivation (pdi)] to kill bacteria growi...

Clindamycin is a lincosamide antibiotic which is approved for the treatment of anaerobic, streptococcal and staphylococcal infections. There has been an increased interest in the use of clindamycin since it achieves high intracellular levels in phagocytic cells, high levels in bone and appears to have an antitoxin effect against the toxin elaborating strains of streptococci and staphylococci. C...

Antibiotic overuse contributes to antibiotic resistance, which is a threat public health. stewardship practice dedicated prescribing antibiotics only when necessary and, are considered necessary, promoting use of the appropriate agent(s), dose, duration, and route therapy optimize clinical outcomes while minimizing unintended consequences use. Because there differences in common infectious cond...

This article discusses the key clinical aspects of empiric therapy of community-acquired pneumonia (CAP). Antibiotic selection, severity of CAP, single vs multiple pathogens, pharmacokinetic considerations, antibiotic resistance, i.v. vs oral antibiotic therapy for CAP, oral therapy for non-ICU hospitalized patients with CAP, beta-lactams, macrolides, ketolides, doxycycline, respiratory quinolo...

conclusions due to the increasing resistance of pathogens to usual empirical antibiotics, it is reasonable to stress upon preventive measures, so that a minimum number of neonates develop sepsis. results coagulase-negative staphylococci (cons) were the most prevalent pathogens isolated from blood specimens in early and late-onset disease. escherichia coli and klebsiella were the most causative ...

PURPOSE To understand if clinicians can tell apart patients with healthcare-associated infections (HCAI) from those with community-acquired infections (CAI) and to determine the impact of HCAI in the adequacy of initial antibiotic therapy and hospital mortality. METHODS One-year prospective cohort study including all consecutive infected patients admitted to a large university tertiary care h...

Ventilator-associated pneumonia (VAP) is the most common nosocomial infection in the ICU. Patients who acquire VAP have higher mortality rates and longer ICU and hospital stays. Because there are other potential causes of fever, leukocytosis, and pulmonary infiltrates, clinical diagnostic criteria are overly sensitive in the diagnosis of VAP. Employing quantitative cultures of bronchopulmonary ...
