In vivo reduction of biofilm seeded on orthopaedic implants.

Aims: Electromagnetic induction heating has demonstrated in vitro antibacterial efficacy over biofilms on metallic biomaterials, although no in vivo studies have been published. Assessment of side effects, including thermal necrosis of adjacent tissue, would determine transferability into clinical practice. Our goal was to assess bone necrosis and antibacterial efficacy of induction heating on biofilm-infected implants in an in vivo setting.

Mycobacterium fortuitum : A Rare Cause of Surgical Site Infection.

Mycobacterium fortuitum is a rapidly growing nontuberculous mycobacterium mainly associated with skin, soft tissue and surgical site infections. We report an unusual outbreak of 6 cases of surgical site infection following spinal surgery. Patients received combined intravenous antibiotics, including amikacin, followed by an extended period of oral therapy with favorable clinical outcomes.

Impact of antibiotic prophylaxis in second-stage surgery in joint prosthesis infection treated with two-stage exchange. A multicenter case-control study.

Introduction: After two-stage exchange due to prosthetic joint infection (PJI), the new prosthesis carries a high risk of reinfection (RePJI). There isn`t solid evidence regarding the antibiotic prophylaxis in 2nd-stage surgery. The objective of this study is to describe what antibiotic prophylaxis is used in this surgery and evaluate its impact on the risk of developing RePJI.

Increase of healthcare-onset Clostridioides difficile infection in adult population since SARS-CoV-2 pandemic: A retrospective cohort study in a tertiary care hospital from 2019 to 2022.

Objectives: The aim was to assess the impact of the SARS-CoV-2 pandemic on the prevalence, relative incidence (RI), incidence density (ID), ratio of rate incidence (RRI), rate of incidence density (RID), and relative risks (RR) of healthcare-onset Clostridioides difficile infection (HO-CDI) as well as its correlation with the antibiotic consumption.

Methods: Demographic and analytical data of adult patients exhibiting diarrhoea and testing positive for C. difficile were systematically collected from a tertiary care hospital in Madrid (Spain).

[Translated article] Descriptive study of spinal instrumentation-related infections in a tertiary hospital.

Introduction: Spinal instrumentation-related infections (SIRI) are one of the main causes of post-surgical complication and comorbidity. Our objective was to describe the clinical and microbiological characteristics, treatment and prognosis of these infections.

Material And Methods: We conducted a retrospective study in our institution (2011-2018) including adult patients undergoing spinal instrumentation who met the diagnostic criteria for confirmed infection.

Description of reinfection of joint prosthesis after 2-stage replacement (infection of the 2nd stage prosthesis): A multicenter study.

Introduction: Two-stage exchange is the gold standard in the surgical management of prosthetic joint infection (PJI). However, perioperative reinfections (RePJI) can occur to newly inserted prosthesis, which highlights the importance of an adequate antibiotic prophylaxis, although there is scarce evidence in this field. Our objective was to evaluate the characteristics of RePJI, its prognosis and the antibiotic prophylaxis that is commonly used in second-stage surgery.

Processing of osteoarticular samples for microbiological diagnosis: Results of a national multi-center survey.

Introduction: Our aim was to evaluate the variability in the processing of osteoarticular samples for microbiological diagnosis between different national centers.

Methods: An online survey with 13 questions was designed and it was sent through SEIMC to the Microbiology Departments of the different centers.

Results: We obtained 72 answers.

Prognosis of unexpected positive intraoperative cultures in arthroplasty revision: A large multicenter cohort.

Background: The positive-intraoperative-cultures-type prosthetic joint infection (PIOC-PJI) is considered when surgical cultures yield microorganisms in presumed aseptic arthroplasty revisions. Herein we assess the risk factors for failure in the largest cohort of PIOC-PJI patients reported to date.

Methods: A retrospective, observational, multicenter study was performed during 2007-2017.

Safety and Efficacy of Prolonged Use of Dalbavancin in Bone and Joint Infections.

Dalbavancin is a lipoglycopeptide with potent activity against Gram-positive microorganisms, a long half-life, a favorable safety profile, and a high concentration in bone, which makes it an interesting alternative for treatment of osteoarticular infections. We performed a multicentric retrospective study of all patients with an osteoarticular infection (septic arthritis, spondylodiscitis, osteomyelitis, or orthopedic implant-related infection) treated with at least one dose of dalbavancin between 2016 and 2017 in 30 institutions in Spain. In order to evaluate the response, patients with or without an orthopedic implant were separated.
