Etiology and antimicrobial resistance patterns in chronic osteomyelitis of the tibia: an 11-year clinical experience.

Purpose: To analyze changes in tendency of etiology and of antimicrobial resistance patterns to most common local and systemic antibiotics in chronic osteomyelitis of the tibia (COM-T) in a Level I trauma center over an 11-year period.

Methods: A retrospective review including all patients with COM-T who were surgically treated from January 2009 to December 2019. Patients were divided into two period groups: 2009-2014 and 2015-2019.

Impact of Prophylactic Norfloxacin in Multidrug Resistant Bacterial Infections in the Early Liver Posttransplant Period.

Objectives: Norfloxacin is indicated as primary or secondary prophylaxis for spontaneous bacterial peritonitis in patients with cirrhosis. A history of spontaneous bacterial peritonitis favors colonization by multidrug-resistant bacteria. Infections caused by these bacteria increase morbidity and mortality after transplant.

Infectious complications of non-surgical biliary tract manipulation in paediatric patients. Role of antibiotic prophylaxis.

Background: Infections related to non-surgical manipulation of the biliary tract (NSMBT) are common events despite periprocedural antibiotic prophylaxis (PAP). Since June 2017, our local protocol has indicated a 24-h regimen of intravenous piperacillin-tazobactam for this purpose.

Objective: We aimed to describe the incidence and characteristics of NSMBT-related paediatric infections, define risk factors for their development, and analyse adherence to our PAP protocol.

Mycotic Aneurysm of Internal Carotid Artery Secondary to Livestock-associated Methicillin-resistant Staphylococcus Aureus Clonal Complex CC398.

The aim of this article is to present a case of mycotic aneurysm of internal carotid artery secondary to livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) treated with resection and common-to-internal carotid artery bypass with autologous vein graft in a male pig farmer. A 69-year-old man, pig farmer, with recent dental extraction was admitted with a right cervical pulsatile mass, dysphonia, pain, leukocytosis and elevated C-reactive protein (CRP). Ultrasonography (US) and computed tomography angiography (CTA) showed a 3.

Role of asymptomatic bacteriuria on early periprosthetic joint infection after hip hemiarthroplasty. BARIFER randomized clinical trial.

Purpose: To evaluate preoperative asymptomatic bacteriuria (ASB) treatment to reduce early-periprosthetic joint infections (early-PJIs) after hip hemiarthroplasty (HHA) for fracture.

Methods: Open-label, multicenter RCT comparing fosfomycin-trometamol versus no intervention with a parallel follow-up cohort without ASB.

Primary Outcome: early-PJI after HHA.

Infectious complications of non-surgical biliary tract manipulation in paediatric patients. Role of antibiotic prophylaxis.

Background: Infections related to non-surgical manipulation of the biliary tract (NSMBT) are common events despite periprocedural antibiotic prophylaxis (PAP). Since June 2017, our local protocol has indicated a 24-h regimen of intravenous piperacillin-tazobactam for this purpose.

Objective: We aimed to describe the incidence and characteristics of NSMBT-related paediatric infections, define risk factors for their development, and analyse adherence to our PAP protocol.

[Serogroup C invasive meningococcal disease in the post-vaccine era and vaccine failures].

Introduction: The incidence of serogroup C invasive meningococcal disease (IMD) has decreased since the introduction of systematic vaccination in 2000. The aim of this study is to determine the number of serogroup C IMD cases diagnosed since then and the vaccine failures.

Patients And Methods: A retrospective analysis was performed on patients diagnosed with IMD by culture or polymerase chain reaction (PCR) in a maternity and childhood hospital in Barcelona between 2001 and 2018.

Does Routine Abdominal Drain Tip Culture Anticipate Post-Operative Infection in Liver Transplantation?

Bacterial infections are a common complication after liver transplantation. Usually, abdominal drains are placed at the end of the surgical procedure. The usefulness of routine drain tip culture has not been investigated.

Routine Bile Culture From Liver Donors as Screening of Donor-Transmitted Infections in Liver Transplantation.

Bacterial infections are an important threat in the early post-liver transplantation period. Donor-transmitted infections, although rare, can have high mortality. The utility of routine culture from the donor bile duct as screening of donor-transmitted infection has not been evaluated.

Donor-derived bacterial infections in lung transplant recipients in the era of multidrug resistance.

Objectives: Our aim was to analyze the prevalence of multidrug-resistant bacterial infections in lung transplant donors and to evaluate its influence on donor-derived bacterial infections.

Methods: We conducted a retrospective study of adult patients who underwent lung transplantation (2013-2016) at our hospital. Donor-derived bacterial infection was defined as the isolation of the same bacteria with identical antibiotic susceptibility patterns in the recipient and the perioperative cultures from the donor during the first month posttransplantation.

Vancomycin-Gentamicin Prefabricated Spacers in 2-Stage Revision Arthroplasty for Chronic Hip and Knee Periprosthetic Joint Infection: Insights Into Reimplantation Microbiology and Outcomes.

Background: Second-stage positive cultures in 2-stage revision arthroplasty are a matter of concern, as their influence in outcomes is not clearly defined. We sought to study reimplantation microbiology when using vancomycin-gentamicin prefabricated cement spacers in hip and knee periprosthetic joint infection. The associations of second-stage positive cultures with treatment failures and patient-associated factors were analyzed.

Septic Nonunion Caused by Mycobacterium canariasense: A Case Report.

Case: A 43-year-old former drug user presented with a mycobacterium-caused septic nonunion of the humeral shaft. The patient had undergone 2 previous surgeries for a hematogenous fracture-related infection due to Staphylococcus aureus. The procedures had included debridement, double-plate osteosynthesis, and placement of a gentamicin-loaded bone substitute.

Native vertebral osteomyelitis in aged patients: distinctive features. An observational cohort study.

Purpose: To describe the demographic, clinical, and microbiological profile of native vertebral osteomyelitis (NVO) in aged patients as compared to that of younger patients, to identify differences that could motivate changes in clinical management.

Methods: Retrospective, observational cohort study (1990-2015) including all adult patients with microbiologically confirmed NVO divided into 2 groups: aged (≥ 65 years) vs younger (18-64 years).

Results: 247 patients included, 138 aged and 109 younger.

Successful liver transplantation despite donor-transmitted ESBL-producing Klebsiella pneumoniae infection: Case report and review of the literature.

Donor-derived bacterial infection is a recognized complication of solid organ transplantation. Patients admitted to the intensive care unit are increasingly exposed to infection with multidrug-resistant microorganisms. However, no specific recommendations are available about their suitability as donors.

Periprosthetic joint infection by Propionibacterium acnes: Clinical differences between monomicrobial versus polymicrobial infection.

Objective: To compare a series of monomicrobial Propionibacterium acnes (P. acnes) knee and hip periprosthetic joint infection (PJI) cases with cases of polymicrobial PJI which included P. acnes.

Molecular diagnosis in HAP/VAP.

Purpose Of Review: This review describes recent findings related to molecular-based methods of potential application in the diagnosis of bacterial hospital-acquired pneumonia (HAP)/ventilator-associated pneumonia (VAP). It focuses on methods capable of providing organism identification and keys of bacterial resistance necessary in clinical and epidemiological management of patients and on their ability to provide quantitative results.

Recent Findings: Significant advances have been made in recent years in the field of molecular diagnosis of bacterial pathogens.
