Filter by:The aim of this study is to adescription of mandibular osteomylitis in patients having had a treatment by DENOSUMAB. Indeed, one of the adverse effect ot this molecule is to induce mandibular infection.
The goal of this study is to figure out the best doses for two antibiotics (called cefadroxil and cephalexin) when they are used to treat bone, joint, or muscle infections in children. In order to do this, the study will collect data about children admitted to Children's Hospital Colorado who have these types of infections. During the study, these patients will receive doses by mouth of each of these antibiotics, in addition to an IV antibiotic (given through a vein) used to treat their infection. After the dose of the first antibiotic, blood samples will be drawn every few hours to measure how much of the drug is still in their body, until it is all gone. After the first antibiotic is out of the patient's body, the same will be done for the second antibiotic. Measurements, in the lab, of how much of these antibiotics are needed to kill the most common bacteria causing these infections, which is a type of "Staph" bacteria called "MSSA", will be taken. Finally, the blood levels of the antibiotics and the information from the lab tests about the Staph bacteria will be used to calculate how much and how often of the antibiotic should be given to children with bone, joint, or muscle infections. Currently, these types of infections are treated with an antibiotic that children have to take four times every day. The goal of this study is to find an antibiotic that children can take only two or three times per day.
Acinetobacter baumannii is an opportunist pathogen that has become increasingly important over recent years as a cause of nosocomial infections. Ventilator-associated pneumonia, central line-associated bloodstream infection and bone and soft tissue infections secondary to open fractures are among the conditions most associated with this agent . Attention is drawn not only to the increasing incidence of this agent over the last few years but also to the rapid worsening of its susceptibility to antimicrobial agents, including carbapenems. Few therapeutic options are available for treating pan-resistant strains: colistin and tigecycline has been used, but resistance to these options frequently emerges in clinical practice. Taking into account the fact that fewer new antimicrobial agents are being validated and introduced into clinical practice, the growing prevalence of isolates with these high levels of resistance is becoming a matter of increasing concern. Certain risk factors have also been correlated with infection related to A. baumannii. The most important are prolonged hospitalization in intensive care units and use of invasive devices. Another important risk factor is severe trauma: A. baumannii is associated with invasive infections, including osteomyelitis following open fracture reduction. Studies that included military personnel and civilians involved in the recent conflicts in Iraq and Afghanistan have shown high prevalence of A. baumannii as causative agent in cases of osteomyelitis secondary to traumatic injuries. Also, in Brazil, a retrospective study that analyzed 101 cases of osteomyelitis due to Gram-negative bacilli showed that A. baumannii was the second most prevalent agent and that it had a high degree of antimicrobial resistance, particularly to carbapenems. The objectives of this retrospective study are: 1. clinically and epidemiologically characterize 241 patients with osteomyelitis related to A. baumannii who were admitted at the Institute of Orthopedics and Traumatology, Hospital das Clínicas, University of São Paulo; 2. to describe the antimicrobial susceptibility profile of A. baumannii strains isolated; 3. to evaluate the patients' outcomes (remission, recurrence, limb amputation or death) according to the antimicrobial treatment used, including tigecycline; 4. to compare efficacy and safety profiles of tigecycline, colistin and ampicillin-sulbactan among patients with carbapenem-resistant A. baumannii related osteomyelitis.
The present trial was aimed to identify which biomarkers could be associated in perioperative period after surgical treatment of tibial fracture to the development of POM.
Bone samples from infected diabetic feet will be collected and tests will be performed for the diagnosis of causative bacteria. Samples will be processed by PCR multiplex tests and usual cultures for identification of causative bacteria and sensitivity to antibiotics. Results obtained by the two methods will be compared in terms of quickness and similarity of germ identification. Usual care strategy will not be modified since results of PCR multiplex tests will not be transmitted to the physicians before the results of usual cultures.
Because of its prolonged terminal half-life, dalbavancin is an extremely attractive option in treating Gram-positive infections caused by S. aureus including MRSA, and streptococcal species. Systemic bacterial infections due to Staphylococci such as osteomyelitis and septic arthritis, are conditions which require prolonged IV therapy, typically for at least 3-6 weeks, though sometimes more. Due to dalbavancin's prolonged terminal half-life, it may offer the opportunity to substantially reduce costs and morbidity in native joint and prosthetic joint infections with one infusion every fourteen days until completion of therapy.
The feet of diabetic patients continue to be an important problem in medicine. In general, patients with diabetic foot have some sort of amputation, especially in underserved populations. It is clearly necessary to develop novel treatment strategies for this worldwide health problem. Photodynamic therapy (PDT) , is a low cost and highly effective alternative treatment concerning infections avoiding amputations in the diabetic foot.
Pressure ulcer represents a frequent clinical condition in patient with spinal cord injury or after prolonged Intensive Care Unit (ICU) stay. Osteomyelitis constitutes a severe complication with a poorly known management, and is associated with a high rate of relapse, leading to a high-burden in hospital bed-days, financial cost, surgical intervention, antibiotic use, morbidity and mortality, and nursing care. In our reference center for bone and joint infection management, the medical and surgical strategies are systematically discussed during pluridisciplinary meetings. Most patients benefit from a two-stage surgical strategy (debridement with initiation of vacuum-assisted closure therapy until reconstruction using muscular flap) with prolonged antimicrobial therapy. In this context, our study aims to evaluate this complex approach and to determine risk factors of treatment failure in order to improve patient management, focusing on optimization of empirical antimicrobial therapy after each surgical stage, delay between the two surgical stage, and duration of antimicrobial therapy.
This was a prospective study performed between November 2011 and September 2013. Patients with a confirmed S. aureus infection after fracture fixation or prosthetic joint infection were included. Exclusion criteria included infections involving external fixation pins, infections without any implanted hardware and culture positive patients not displaying any clinical sign of infection. The following surgical parameters were documented: affected bone or joint; type of implant; time between implantation of the device and onset of symptoms. Personal characteristics and patients`health status were also documented. Any revision surgeries involving the site of interest and all isolated pathogens were recorded throughout the course of treatment and follow-up. A follow up examination was performed an average of 23 months after discharge. Primary outcome at follow up was cure. Cure was defined by the authors as: missing local (at site of interest) or systemic signs of infection, terminated surgical and systemic therapy and restoration of joint or limb function. At the first surgical procedure after enrolment, at least four deep bone biopsies were taken from the interface between implant and affected bone. Identification and antibiotic susceptibility testing of all growth was performed. Multi-drug-resistance (MDR) was defined according to the definitions of the European Committee of Antimicrobial Susceptibility Testing (EUCAST). Biofilm formation was analysed and quantified in microtitre plate assays according to protocol of Stepanovic et al.(see references).
Fifty-one patients suffering from chronic post-traumatic or postoperative osteomyelitis of the lower extremities were included in the retrospective investigation. The patients were assigned to the study group of the combination therapy with antibiotic-loaded calcium sulfate and antibiotic-loaded PMMA or the control group of the antibiotic-loaded PMMA. Hematological parameters, eradication of infection, rate of infection recurrence and reoperation rate were evaluated during the follow-up.
