Nosocomially-acquired multi-, extensively-, and pandrug resistant (MDR, XDR, and PDR) strains of microorganisms such as Acinetobacter baumannii remain a serious cause of infection and septic mortality in burn patients. Treatment of patients with nosocomial burn wound infections is often complicated by drug-resistant strains of A. baumannii. Today, many researchers are focusing on the investigation of novel non-antibiotic strategies such as photodynamic therapy (PDT). We report a new PDT strategy that suppresses colistin resistance in PDR A...

Although single-drug therapy may prove insufficient in treating bacterial infections or inflammation after orthopaedic surgeries, complex therapy (using both an antibiotic and an anti-inflammatory drug) is thought to address the problem. Among drug delivery systems (DDSs) with prolonged drug release profiles, nanoporous anodic titanium dioxide (ATO) layers on Ti foil are very promising. In the discussed research, ATO samples were synthesized via a three-step anodization process in an ethylene glycol-based electrolyte with fluoride ions...

BACKGROUND: Cystic fibrosis lung disease is generally a diffuse process however rarely one lung may become particularly damaged through chronic collapse and consolidation resulting in end-stage bronchiectasis with relative sparing of the contralateral lung. This clinical situation is sometimes referred to as "destroyed lung". Lung resection surgery is seldom indicated in cystic fibrosis and the associated medical literature is relatively sparse. CASE PRESENTATION: A 14 year old boy was referred to our centre for lung transplantation assessment...

Background Treatment of musculoskeletal infections principally consists of radical surgical debridement and systemic administration of antibiotics. Additional local antibiotic therapy is not yet generally established, and lacks evidence-based proof of efficacy. Nonetheless, there are a variety of practical approaches, as most specialised departments are unwilling to forego this option. The established polymethylmetacrylate (PMMA) carrier system has a number of practical disadvantages. This has led to the increased use of absorbable carrier systems, and those based on calcium sulphate have given particularly encouraging results...

Sinusitis is a common finding in avian species; however, it presents unique treatment challenges in ratites. A 6-yr-old male greater rhea ( Rhea americana ) presented acutely with right infraorbital sinus swelling and chemosis. Oral antibiotics were prescribed based on bacterial culture results with incomplete resolution of clinical signs. A computed tomography scan of the skull demonstrated a mixed-density soft tissue mass with extensive destruction of the right nasal bone, hard palate, maxilla, and frontal bone...

INTRODUCTION: Febuxostat, a nonpurine xanthine oxidase inhibitor, is approved as the first-line urate-lowering therapy in gout patients with normal renal function or mild to moderate renal impairment. The most common adverse effects of febuxostat are liver function test abnormalities, diarrhea, and skin rash. However, there is insufficient data in patients with severe renal impairment and end-stage renal disease (ESRD). We report the first case, to our knowledge, in which agranulocytosis developed after febuxostat treatment in an ESRD patient...

PURPOSE OF REVIEW: Increasing antimicrobial resistance is a worldwide phenomenon that is threatening public health. Lower respiratory infections are one of the leading causes of morbidity that contribute to antibiotic consumption and thus the emergence of multidrug-resistant microbial strains. The goal of shortening antibiotic regimens' duration in common bacterial infections has been prioritized by antimicrobial stewardship programs as an action against this problem. RECENT FINDINGS: Data coming from randomized controlled trials, meta-analyses, and systematic reviews support the shortening of antimicrobial regimens in community-acquired, hospital-acquired, and ventilator-associated pneumonia...

Periodontal disease is an inflammatory disorder affecting the supporting teeth structures, including gingiva, periodontal ligament and alveolar bone, causing loss of connective tissue, reabsorption of alveolar bone and formation of periodontal pockets. The aim of this study is to find a correlation between bacterial growth and periodontal disease. Fifty-seven patients aged between 21 and 65 years, median age 46 years, were enrolled. According to gingival pocket depth, ranging from 3 to 7 mm, patients were divided into two groups: the first (30 patients, 53%) with deep pockets ³ 5 mm and the second (27 patients, 47%) less than 5 mm...

INTRODUCTION: Cost-containment strategies are shifting the treatment of acute bacterial skin and skin structure infections (ABSSSI) from inpatient to outpatient settings. Current standard of care (SoC) requires multiple-dose regimens, which are associated with high hospitalization rates and high costs. Oritavancin, a new single-dose antibiotic for ABSSSI, may be suitable for outpatient therapy. This analysis evaluates the effectiveness, costs, and resource utilization of oritavancin vs...

Medication-related osteonecrosis of the jaw (MRONJ) has been associated with medications that include bisphosphonates (BPs), denosumab, bevacizumab and sunitinib. Ziv-aflibercept is a recombinant human vascular endothelial growth factor (VEGF) receptor which has been used to treat patients with various advanced solid tumors. We report three patients without a history of the use of medications known to cause MRONJ presenting with jaw osteonecrosis typical for MRONJ following therapy with ziv-aflibercept. All patients had metastatic gastrointestinal cancer treated with ziv-aflibercept and were evaluated for MRONJ because of exposed bone in the oral cavity...

OBJECTIVES: Healthcare facilities internationally have grown outpatient parenteral antibiotic administration services for the last few decades. The literature contains publications from dozens of countries describing systematized processes with specialist oversight and their levels of service provision and outcomes. Such descriptions are absent in the majority of Asian countries. We sought to elucidate the extent and nature of outpatient parenteral antibiotic therapy (OPAT) in Asia and to consider the ramifications and opportunities for improvement METHODS: Utilizing colleagues and their personal networks, we surveyed healthcare facilities across 17 countries in Asia to ascertain the current means (if any) of providing OPAT...

Innovative approaches to the use of existing antibiotics is an important strategy in efforts to address the escalating antimicrobial resistance crisis. We report a new approach to the treatment of methicillin-resistant Staphylococcus aureus (MRSA) infections by demonstrating that oxacillin can be used to significantly attenuate the virulence of MRSA despite the pathogen being resistant to this drug. Using mechanistic in vitro assays and in vivo models of invasive pneumonia and sepsis, we show that oxacillin-treated MRSA strains are significantly attenuated in virulence...

BACKGROUND: The number of viral pathogens associated with pediatric acute respiratory tract infection (ARI) has grown since the introduction of reverse transcription real-time polymerase chain reaction (RT-PCR) assays. Multiple viruses are detected during a single ARI episode in approximately a quarter of all cases. The clinical relevance of these multiple detections is unclear, as is the role of the individual virus. We therefore investigated the correlation between clinical data and RT-PCR results in children with single- and multiple viral ARI...

OBJECTIVE: Lyme arthritis (LA) is caused by infection with Borrelia burgdorferi and usually resolves following spirochetal killing with antibiotics. However, in some patients, arthritis persists after antibiotic therapy. To provide insights into underlying pathogenic processes associated with post-infectious LA, we analyzed differences in microRNA expression between LA patients with active infection compared with those with post-infectious LA. METHODS: MicroRNA expression was assayed in synovial fluid (SF) from LA patients before and after oral and IV antibiotic therapy, and from synovial tissue from post-infectious LA patients obtained months after antibiotic therapy...
