The results of 78 resections of the head and neck of the femur (Girdlestone pseudarthrosis) in patients with infected hip replacements were studied. The mean follow-up was 5 years. At the time of the resection, gram-positive organisms were found in 53% of the cases, gram-negative in 33%, and in 12% there were mixed flora. The Girdlestone pseudarthrosis(More)
PURPOSE The relationship between pyogenic vertebral osteomyelitis and infectious endocarditis is uncertain. This study investigates the incidence and risk factors of infectious endocarditis in patients with pyogenic vertebral osteomyelitis, and the outcome of pyogenic vertebral osteomyelitis with and without associated infectious endocarditis. METHODS A(More)
Two-stage revision using aminoglycoside-cement spacers (A-CSs) is widely used to manage chronic periprosthetic joint infection (PJI). However, aminoglycoside-resistance in gram-positive cocci (GPC) seems to be increasing. Moreover, the contribution of these A-CSs to select resistant mutants is a matter of concern. We study the antibiotic susceptibility(More)
Arthroscopic revision of rotator cuff lesions is an increasingly popular procedure with a relatively safe profile. However, associated deep articular infection has been described, with potentially destructive joint sequelae. When occurring, it poses the double challenge of eradicating the infectious agent while preserving the articulation and its function.(More)
Facklamia spp. are gram-positive cocci first described in 1997. They are α-hemolytic, facultative anaerobes, catalase-negative cocci, resembling viridians streptococci on 5% sheep blood agar. Facklamia hominis is, by far, the most common species of the 6 so far described, and it is thought that its natural habitat is the female genital tract. Four previous(More)
Preoperative identification of the infecting micro-organism is of paramount importance in the treatment protocol for chronic periprosthetic joint infections, as it enables selection of the most appropriate antibiotic treatment. Preoperative joint aspiration, the most commonly used sampling technique, has proven to have a broad range of sensitivity values(More)
Tuberculous trochanteric bursitis (TTB) is a rare condition. Clinical management varies considerably and recurrence is common. This report presents 5 new cases of TTB and a review of the literature (1981-2003), with emphasis on clinical and radiological findings and treatment, in order to investigate the optimum therapeutic approach.
BACKGROUND Industrially preformed antibiotic-loaded cement spacers are useful to facilitate the second stage of two-stage exchange arthroplasty for infected THAs and TKAs. However, whether gentamicin alone or a combination of antibiotics (such as vancomycin and gentamicin) is more effective is not known. QUESTIONS/PURPOSES We therefore sought to compare(More)
In this work, last results of the research project “Development of an Intelligent Data Analysis System for Knowledge Management in Environmental Data Bases (DB)” are presented. The project is focussed on the design and development of a prototype for Knowledge Discovery (KD) and intelligent data analysis, and specially oriented to environmental DB. It is(More)
