Staphylococcus aureus infections of the skin and soft tissue pose a major concern to public health, largely owing to the steadily increasing prevalence of drug resistant isolates. As an alternative mode of treatment both bacteriophage endolysins and bacteriocins have been shown to possess antimicrobial efficacy against multiple species of bacteria including otherwise drug resistant strains. Despite this, the administration and exposure of such antimicrobials should be restricted until required in order to discourage the continued evolution of bacterial resistance, whilst maintaining the activity and stability of such proteinaceous structures...

BACKGROUND: Complex immunophenotypic repertoires defining discrete adipose-derived stem cell (ASC) subpopulations may hold a key toward identifying predictors of clinical utility. To this end, we sorted out of the freshly established ASCs four subpopulations (SPs) according to a specific pattern of co-expression of six surface markers, the CD34, CD73, CD90, CD105, CD146, and CD271, using polychromatic flow cytometry. METHOD: Using flow cytometry-associated cell sorting and analysis, gating parameters were set to select for a CD73(+)CD90(+)CD105(+) phenotype plus one of the four following combinations, CD34(-)CD146(-)CD271(-) (SP1), CD34(-)CD146(+)CD271(-) (SP2), CD34(+)CD146(+)CD271(-) (SP3), and CD34(-)CD146(+)CD271(+) (SP4)...

International guidelines in peritoneal dialysis (PD) advocate for regular application of topical mupirocin in chronic PD exit-site care. A strong evidence base links this treatment to reduced rates of exit-site infections and peritonitis. However, emerging reports of increasing mupirocin resistance and gram-negative infections are threatening the long-term viability of topical antibiotic ointments as a prophylactic treatment. Medical grade honey has multiple proven antibacterial and wound healing properties...

OBJECTIVE: Seasonal variations in temperature exert strong selective pressure on microorganism population dynamics and should be taken into account in epidemiological studies. The objective of current study was to characterize the seasonal variation of Staphylococcal infections in respect to patient location, specimen source, month of year, and temperature variation. METHOD: A retrospective longitudinal time series analysis of methicillin-resistant and sensitive S...

Childhood burns are a profoundly traumatic and painful experience. Despite recognition of the prevalence of burn injuries in children and the severity of the associated pain, burn pain remains undertreated. At the same time, more evidence is emerging to suggest that undertreated pain has serious long-term medical and psychiatric consequences, many of which can be ameliorated with improved pain control. Pain in burn patients is, however, notoriously difficult to treat, perhaps because there is a chronic pain aspect underlying the acute pain that accompanies wound care and procedures...

Acinetobacter baumannii is a leading pathogen responsible for nosocomial infections. The emergence of carbapenem-resistant A. baumannii (CRAB) has left few effective antibiotics for clinicians to use. To investigate the temporal evolutionary relationships among CRAB strains, we collected 248 CRAB isolates from a Chinese burns institute over 3 years. The prevalence of the OXA-23 gene was detected by polymerase chain reaction. Multilocus sequence typing was used to type the CRAB strains and eBURST was used to analyze their evolutionary relationships...

BACKGROUND: Propionibacterium acnes is a common pathogen identified in postoperative shoulder infection. It has been shown to be present in culture specimens during primary shoulder arthroplasty; however, recent work has suggested that it is most likely to be a contaminant. Our aim was to identify the potential sources of contamination in shoulder arthroplasty. METHODS: Tissue swabs were obtained for microbiological analysis from consecutive patients undergoing primary shoulder arthroplasty...

Previous research has demonstrated that veterans with posttraumatic stress disorder (PTSD) are at higher risk for aggression, hostility, and anger, potentially leading to problems with the law or disciplinary action while in the military. There have been calls for increased consideration of the unique aspects of the judicial system in legal matters with veterans involved. The bulk of the research so far has considered the link between PTSD, traumatic brain injury (TBI), and combat exposure, but little is known about the potential role of chronic pain and Military Sexual Trauma (MST) in a veteran's experience of anger, aggression, and discipline while in the military and legal concerns...

Chronic hyperglycemia is associated with impaired wound healing and higher susceptibility to infections. It is unclear whether patients with diabetes mellitus (DM) present more oral mucosal disorders compared to control groups. The objectives were to compare (a) the prevalence rates of oral mucosal disorders in the DM and non-DM population and (b) the prevalence rates of specific disorders in the DM and non-DM population. Full-text articles were included if they met the following inclusion criteria: (a) they must be original articles from scientific journals, (b) they must be only cross-sectional studies in English, (c) the prevalence of oral mucosal disorders in DM patients must be evaluated, (d) results must be compared with a healthy control group, and (e) oral mucosal disorders must be specified in DM and non-DM group...

OBJECTIVES: The aim of the present study was to evaluate the effectiveness of platelet-rich fibrin (PRF) as a wound-healing accelerator in patients undergoing oral bisphosphonate therapy and requiring tooth extractions. MATERIALS AND METHODS: A total of 102 patients were divided into a PRF group and control group. The patients received oral bisphosphonate therapy for osteoporosis for an average of 32 months. Blood was collected and PRF was introduced into the socket of the PRF group only...

BACKGROUND: Urethral stricture disease is prevalent, and many surgical techniques have been developed to treat it. Currently, urethroplasty for bulbar strictures implies ventral or dorsal stricturotomy and a buccal mucosa graft (BMG) patch. OBJECTIVE: To describe the surgical approach of the ventral patch BMG urethroplasty for proximal bulbar urethral stricture and to analyze 11 consecutive cases for whom the technique was used. PATIENTS AND METHODS: The diagnosis of urethral stricture was confirmed with a combined retrograde urethrography and micturating cystourethrography...

BACKGROUND: The emergence and prevalence of multidrug resistant (MDR) pathogenic bacteria poses a serious threat to human and animal health globally. Nosocomial infections and common ailments such as pneumonia, wound, urinary tract, and bloodstream infections are becoming more challenging to treat due to the rapid spread of MDR pathogenic bacteria. According to recent reports by the World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC), there is an unprecedented increase in the occurrence of MDR infections worldwide...

PURPOSE: To determine the prevalence of postkeratoplasty fungal infection when corneal tissue from donors with a recent medical history of oral thrush or respiratory, urine, wound, sputum, bronchial, tracheal, or throat culture positive for fungus is identified before recovery and after decontamination of the corneal tissue with 5% povidone-iodine flush to the donors' eyes during recovery. METHODS: This is a prospective analysis of corneas from 42 donors with a documented medical history of fungus or positive fungal culture, which were recovered between January 2010 and November 2010...

INTRODUCTION: Given the high prevalence of diabetes and burning injury worldwide, it is essential to dissect the underlying mechanism of delayed burn wound healing in diabetic subjects, especially the high glucose induced HIF-1-mediated transcription defects. MATERIALS AND METHODS: Human umbilical vein endothelial cells (HUVECs) were cultured with low or high concentrations of glucose. HIF-1α induced VEGF transcription was measured via luciferase assay. Immunofluorescence staining was performed to visualize CREB localization...
