INTRODUCTION Health care workers have an increased risk of infection due to occupational Mycobacterium tuberculosis exposure, including multidrug-resistant strains. Health care workers' risk of developing tuberculosis is greater than that of the general population, whether in low-, intermediate- or high-incidence countries. Adherence to infection control measures (administrative controls, environmental controls, and personal respiratory protection) is essential to reduce risk of disease transmission between suspected tuberculosis patients and health care workers, but for different reasons, both objective and subjective, adherence is low...

Methicillin-resistant Staphylococcus aureus (MRSA) have developed resistance to antibiotics of last resort such as vancomycin, linezolid and daptomycin. Additionally, their biofilm forming capability has set an alarming situation in the treatment of bacterial infections. Herein we report the potency of fatty acid comprising lysine conjugates as novel anti-MRSA agents, which were not only capable of killing growing planktonic MRSA at low concentration (MIC = 3.1-6.3 µg/mL), but also displayed potent activity against non-dividing stationary phase cells...

BACKGROUND: Surgical site infections (SSI) are one of the most frequent postoperative complications worldwide and preventive measures are still an important research topic. High infection rates are not uncommon, especially in visceral surgery. At the same time, frequently not all evidence-based measures are carried out in a standardized manner. The aim of this article is to summarize the relevant literature on evidence-based measures for prevention of SSI. Although evidence-based medicine has already become well-established in surgery, the opinion of experts often still prevails...

Scope and Significance: The topical use of antiseptics for wound care has a role in an antimicrobial stewardship strategy. However, the details of this role need clarification. Further clinical research into the use of topical antiseptics in wound care would lower the risk of furthering antibiotic resistance and contribute to more effective antibiotic use. As part of this research, experimental and surveillance data are needed on the resistance and tolerance patterns associated with topical antiseptic use in wound infections...

Reactive oxygen species (ROS), when combined with various delivery mechanisms, has the potential to become a powerful novel therapeutic agent against difficult-to-treat infections, especially those involving biofilm. It is important in the context of the global antibiotic resistance crisis. ROS is rapidly active in vitro against all Gram-positive and Gram-negative bacteria tested. ROS also has antifungal and antiviral properties. ROS prevents the formation of biofilms caused by a range of bacterial species in wounds and respiratory epithelium...

Atopic dermatitis (AD) is a biphasic inflammatory skin disease that is provoked by epidermal barrier defects, immune dysregulation, and increased skin infections. Previously, we have demonstrated that bvPLA2 evoked immune tolerance by inducing regulatory T cells (Treg), and thus alleviated Th2 dominant allergic asthma in mice. Here, we would like to determine whether treatment with bvPLA2 exacerbates the AD-like allergic inflammations induced by house dust mite extract (DFE) in a murine model. Epidermal thickness, immune cell infiltration, serum immunoglobulin, and cytokines were measured...

From May 2008 to December 2013, 320 cases of otitis externa were diagnosed among 2012 dogs undergoing routine physical examinations at Celtic Creatures Veterinary Clinic, Sydney River, Nova Scotia for a diagnosis frequency of 15.9% [95% confidence interval (CI): 14.3% to 17.6%]. Twenty-four percent of these dogs exhibited 1 or multiple recurrences despite initial treatment with topical antimicrobial/anti-inflammatory solutions. The frequency of diagnosis was significantly higher in breeds with pendulous ears, but was not affected by ear hairiness...

BACKGROUND: Cryptococcus neoformans is an encapsulated yeast causing mainly opportunistic infections. The virulence factors involved in cryptococcosis pathogenesis include the presence and the size of the polysaccharide capsule, the production of melanin by phenoloxidase, the growth at 37°C and the enzyme secretion like proteinase, phospholipase and urease. Many other enzymes are secreted by C. neoformans but their role in the fungus virulence is not yet known. AIMS: In order to investigate this topic, we compared the phospholipase production between strains from patients and from bird droppings, and we examined its relationship to phenoloxidase production...

Since the initial design of surgical theaters, the thermal environment of the operating suite itself has been an area of concern and robust discussion. In the 1950s, correspondence in the British Medical Journal discussed the most suitable design for a surgeon's cap to prevent sweat from dripping onto the surgical field. These deliberations stimulated questions about the effects of sweat-provoking environments on the efficiency of the surgical team, not to mention the effects on the patient. Although these benefits translate to implant-based orthopedic surgery, they remain poorly understood and, at times, ignored...

Vaccination in immunocompetent adult mainly concerns booster vaccination against diphtheria, tetanus, polio and pertussis. Some chronic diseases may also require the achievement of pneumococcal and influenza vaccines. In addition, from the age of 65, annual influenza vaccination as well as one dose of a live attenuated shingles vaccine between 64 and 75 years are recommended. Immunocompromised adults, due to the increased risk of serious infections responsible of significant morbidity and mortality, are particularly concerned by vaccination...

Reactive oxygen species (ROS) is a novel therapeutic strategy for topical or local application to wounds, mucosa or internal structures where there may be heavy bacterial bioburden with biofilm and chronic inflammation. Bacterial biofilms are a significant problem in clinical settings owing to their increased tolerance towards conventionally prescribed antibiotics and their propensity for selection of further antibacterial resistance. There is therefore a pressing need for the development of alternative therapeutic strategies that can improve antibiotic efficacy towards biofilms...
